• steel for rollers in a small benchtop rolling mill?

    From pyotr filipivich@21:1/5 to All on Wed Mar 16 15:48:50 2022
    Greetings

    I have a small bench top rolling mill. Works fin as long as I
    don't over do it.
    But, the rollers are flat. I'd like to put a custom pattern (or
    two) on thin brass / copper stock which will require something.
    Option A is to punch the pattern into a piece of flat steel and
    roll it through. Not a bad idea, but kind of limited to lengths of
    out put. (Some of this will be for decorating wooden boxes).
    Plan B would be to put the pattern into a roller so I can just
    crank out as many feet as I have material. "It will all get used
    sometime."
    The issue for custom rollers is of course, what is the best grade
    of steel for the rollers, and heat treating it after engraving. (Hmmm
    'I just had an idea forming in my brain...')

    The rollers are going to be about 2 to 3 inches long and about
    "this" diameter. (I really should unpack it and see what the actual
    sizes are...)

    Now, where I'm going to find the machine to do this is a complete second question.

    Realistically you have two choices.  A CNC 4th axis mill, or hand
    engrave it.  You might be able to do simple knurl patterns with a lathe,
    but I don't think that's really what you are looking for.

    I am sure somebody has better options, but my hammer is a CNC mill with
    a 4th axis rotab and center.  Your job looks like a nail to me.

    I expect OD need not be exact since your machine has to be adjustable.
    You would just need to get it in the right range.

    As to metal choice.  The best option would be a good tough tool steel
    for longest life.  S7 maybe, but 4140 HT (RC30(+/-)ish) would last a
    while for softer metal rolling, and it can be hardened and tempered in
    the RC50+ range.  It would last a modestly long while, and its easier to work with in my opinion than some of the really tough tool steels.

    Of course if you are trying to roll form a hard metal all bets are off.

    I could have sworn I saw nearly this same question somewhere else very recently.

    4140 HT is easy enough to machine with HSS. Do you have hands-on experience hardening and tempering it?

    One night in TIG class I got frustrated with burn-through and took to piling
    up beads as sculpture and text. It worked better than I expected and with a little practice I could make smooth rounded raised lines. Someone with more artistic skill might be able to create raised rolling dies that way. I think the edges could be refined with a curved riffling file with a safe edge
    ground on the bottom.

    4140 HT is easy enough to machine with HSS.

    I quit using HSS except when I need a tool I can't buy or make out of
    carbide. I recently made a flexure out of 4140HT tool (I have a lot of
    it left over from a job) to hold a insert type parting blade. I fought
    with it for a while with some HSS tooling, and then I said screw this
    SHIT (yes I said SHIT in all caps, picked up an Altin Coated carbide
    mill and just ripped through it with a great finish. I was almost
    maxing out the power feed and still getting a great finish. Same thing
    on the lathe. If I don't have a carbide tool the right geometry I make
    one. Everything cuts better.

    Do you have hands-on
    experience hardening and tempering it?

    Nothing that required a high precision final dimension. Most folks will
    tell you to quench in oil, but thick heavy pieces can quench in water.
    Then I just toss it in the toaster over I use for powder coating small
    parts and let it bake for a while. I don't recall the temperature or
    time. I always look it up. One thing I did find s that its hard (for
    me anyway) to surface grind 4140 that has any level or not annealed
    hardness and not have it warp and twist. I really need to setup coolant
    on my surface grinder and see if that helps.

    Now that's an interesting thought. Most of your ER70S wire is harder
    than mild steel, and if you wanted to get crazy maybe you could use hard
    facing wire.


    Your customer Keith Snyder says hi.


    Mine? I just took a quick look and I see several Keiths, but no
    Snyders. Back when I was contracting I had a few Snyder's as customers,
    but I quit contracting December 31st 2016. I'd have to go fire up the
    old computer up front to look anybody up from back then. Haven't turned
    that computer on in nearly five years. Not since I filed my last income
    taxes on that business.
    Now there is a thing that sometimes (often) happens. I get people who
    have gotten frustrated trying to contact a mold maker by the name of
    Shawn Collins. They want him to do a custom job or modify a stock
    design, and it turns out for some stupid reason they think Bob La Londe
    sounds just like Shawn Collins. They will swear they have a bunch of
    molds I made. One guy on Facebook the other day showed me pictures. I
    didn't make a single one of the molds he showed me. It happens at least
    once or twice a week. I've had it happen several times in a day. One
    day I was out fishing with a buddy of mine telling him about it and my
    cell phone rang. It took me five minutes to get the guy on the phone to
    stop talking long enough for me to tell him I didn't make the mold he
    was asking about. Back in the 80s Rick Springfield wrote the song
    "Bruce." I understand completely.

    -----------------------
    I can mill with carbide but it chips too easily on my worn 1965 lathe, and I can't resharpen it on my surface grinder as easily as HSS. HSS is still practical for one-off jobs on small manual machine tools, i.e home hobby
    shops. When I suggest HSS I imply that I've found it an acceptable minimum
    to cut steel of some hardness, not that it's better than carbide. I make cutters from hardened tool steel too, but the difficulty of correctly
    tempering it and low allowable cutting rate mean I don't usually suggest it. -----------------------

    -----------------------
    That's what the blacksmith/knife maker told me to do. I had acquired a small industrial tube oven so I set it up with exhaust pipe tube and a
    thermocouple heat controller to temper with better control, at the 350-375F
    he recommended for 5160 car spring steel. The color is a very faint yellow. -----------------------

    -----------------------
    I inherited a splitting maul that had been used to smooth an uneven granite step and rebuilt the missing cutting edge with either ER70S or 7014 (?). As-welded it was a good fileable hardness for a wood cutting impact tool. Damaging the maul was preferable to refusing grandmother's demands. -----------------------

    Sorry , that was a bit harsh, but I get really tired of the number of
    people telling folks to use HSS or that HSS is better. About the only
    thing I really found HSS was better at was harsh interrupted turning.
    It will hammer away without shattering. HSS is relatively cheap and
    comes in convenient blanks for making tools, but I can touch up a piece
    of carbide on the diamond wheel, and touch up the edge on diamond bench
    stone. I can make good HSS tools, but even back when I was still using
    the mini lathe I found I liked carbide inserts better. I just had to
    use the smallest ones. Sure you can't really use their full capability,
    but they do work. I did spend a lot of time chasing parts with HSS,
    because everybody said so...

    As to grinding. I kind of wished I had not wasted my money on the
    surface grinder. Sure I use it occasionally, but the D-Bit style Tool &
    Cutter has proven to be a far more useful piece of machinery and it cost
    less. I should have bought it first. Mine came with a white Aluminum
    oxide cup wheel and a diamond cup wheel. It uses 5C collets and has a
    couple other attachments. It didn't come with a tracer for sharpening
    helix tools, but I could make one. Its not like a wire finger is a big
    deal. Since I do mostly CNC work day to day I don't want a bunch of
    normal looking resharpened end mills of unknown size laying around
    anyway. The one thing I picked up to go with it was a couple thin
    diamond wheels for slicing off end mills. It serves two purposes. I
    can turn a mill with broken tips into a usable side mill very quickly.
    Just lop off the end (at a slight angle to relieve the bottom). No more
    end cutting capability, but its still useful. The other is simply
    cutting off the flutes quickly to make a blank. Some guys leave the
    flutes on and just make their tool on the other end, but I am paranoid
    about damaging tool holders and collets with those flutes still on the
    tool. One tip I picked up from Steffan Gottswinter's videos was that
    while it is a semi precision grinding tool you can free hand tiny little features with it too. Recently when making a ten degree dovetail cutter
    I put a very slight radius on the tip free hand.

    I did recently (few months ago) make a wrench for a guy who owns a
    hardware store. I don't recall his name. Of course I don't remember
    the name (off hand) of everybody who ever bought a mold, but usually
    they sound familiar. It takes seconds to do an email search back to as
    far as mid 2017.

    -----------------------

    My surface grinder was intended to double as a cutter grinder. The head
    swivels for cup and saucer wheels. As a machine with too many joints it's
    more adaptable than precise. https://www.sterlingmachinery.com/used-delta-milwaukee-toolmaker-surface-grinder.html
    I found the swivel table with dead centers for it, made the missing base,
    and have sharpened some large taps. I have fixtures to grind the ends and
    sides of end mills and circular horizontal milling cutters, and compound
    angles on lathe bits. I think they were available second-hand because they aren't good enough for CNC, but they are OK for a hobby shop.

    Once I fit the taper attachment to the lathe and finish some spindle taper adapters (like Sopko 00815) for the grinder I'll be able to mount the
    diamond wheels I have on it and grind carbide. That'll likely be after we achieve permanent world peace.

    I have a small bench top rolling mill. Works fin as long as I

    But, the rollers are flat. I'd like to put a custom pattern (or

    Option A is to punch the pattern into a piece of flat steel and
    roll it through. Not a bad idea, but kind of limited to lengths of
    out put. (Some of this will be for decorating wooden boxes).
    Plan B would be to put the pattern into a roller so I can just
    crank out as many feet as I have material. "It will all get used

    The issue for custom rollers is of course, what is the best grade
    of steel for the rollers, and heat treating it after engraving. (Hmmm

    The rollers are going to be about 2 to 3 inches long and about
    "this" diameter. (I really should unpack it and see what the actual
    sizes are...)

    Now, where I'm going to find the machine to do this is a complete

    Realistically you have two choices. A CNC 4th axis mill, or hand
    engrave it. You might be able to do simple knurl patterns with a lathe,
    but I don't think that's really what you are looking for.

    I am sure somebody has better options, but my hammer is a CNC mill with
    a 4th axis rotab and center. Your job looks like a nail to me.

    I expect OD need not be exact since your machine has to be adjustable.
    You would just need to get it in the right range.

    As to metal choice. The best option would be a good tough tool steel
    for longest life. S7 maybe, but 4140 HT (RC30(+/-)ish) would last a
    while for softer metal rolling, and it can be hardened and tempered in
    the RC50+ range. It would last a modestly long while, and its easier to
    work with in my opinion than some of the really tough tool steels.

    Of course if you are trying to roll form a hard metal all bets are off.

    My first untutored silversmithing project, in an Army craft shop in
    Heidelberg, was a hollow silver ball pierced with filed patterns. I had
    enough general metalworking experience that it wasn't difficult to figure
    out how.

    http://www.thehomesteadcraftsman.com/2017/02/hammer-and-chisel-engraving-traditional.html

    The ball that the vise mounts on isn't hard to turn on a lathe if you don't need it perfectly smooth. I made some from cast iron dumbbells by writing a spreadsheet that calculated the sphere's X and Y coordinates (X^2 + Y^2 =
    R^2) and having it print tables of them with decreasing radius and step
    sizes, which I followed on the lathe, repeating until the steps were small enough to file. Decreasing the radius fixes undercutting errors. I worked quickly and rather crudely on the large roughing steps and took more care as they approached a smooth sphere. They are ball and socket pivots for a
    hoist frame that helped move a 2100 Lb log onto my sawmill last year.

    I used the same method this afternoon to make a tapered bushing.

    Now, where I'm going to find the machine to do this is a complete

    Realistically you have two choices. A CNC 4th axis mill, or hand
    engrave it. You might be able to do simple knurl patterns with a lathe,
    but I don't think that's really what you are looking for.

    I am sure somebody has better options, but my hammer is a CNC mill with
    a 4th axis rotab and center. Your job looks like a nail to me.

    I expect OD need not be exact since your machine has to be adjustable.
    You would just need to get it in the right range.

    As to metal choice. The best option would be a good tough tool steel
    for longest life. S7 maybe, but 4140 HT (RC30(+/-)ish) would last a
    while for softer metal rolling, and it can be hardened and tempered in
    the RC50+ range. It would last a modestly long while, and its easier to
    work with in my opinion than some of the really tough tool steels.

    Of course if you are trying to roll form a hard metal all bets are off.

    Brass, copper, aluminum

    if the pieces are not large it might also be practical to use a straight
    press with flat embossing die as opposed to a roller.

    Did you ask this in another group? Facebook? Home Shop Machinist?

    I could have sworn I saw nearly this same question somewhere else very
    recently.

    Nope, but I wouldn't be surprise.

    I have talked with a friend who would like a custom roller for
    silver work.


    The first thing I might do is ask the manufacturer of the roller if they
    have any embossing die rollers available. I might search for groups
    where others might have the same or similar roller.

    I think there are two approaches I might consider.

    One is a single roller for embossing your detail, and a second roller
    made of a hard rubber or foam that gives just enough to allow your
    pattern to be imprinted.

    My other thought would certainly be more expensive and have design and
    material thickness limitations so I'll dismiss it for now.

    Hmmm ... "But I have a Roller!"

    I have considered 'engraving' a flat plate and using that. Which
    still leaves me with the issue of making the pattern on the flat
    plate. I've also thought about using a flat plate in a "tracer" set
    up, but that is way more complicated. Than what? dunno, but I'm sure
    it is.
    I am reminded of a computer program I wrote decades ago. Took
    about 3 weeks (and a quarter's computer time). It probably would have
    taken me less time to run the calculations by hand, but I now have
    (had) a program to run those numbers anytime I wanted.
    Same here: making the pattern, how ever I do it, will probably
    take longer than if I just do it by hand. OTOH, I can literally crank
    out feet of the fancy banding once done.

    Long running computer programs - TANGENT ALERT. Some years back my
    geology instructor in college told me I had an A even if I bombed the
    final exam. So made a big show of it when I got up and walked out with
    a week of classes left. I was just being an ass and having a little fun
    of course. I stopped by his office later to make sure he took it in
    fun. While I was there he showed me a water saturation model he was
    running that took "only" a couple days to execute each time he changed a parameter running on his brand new state of the art 386 computer running
    a BASIC interpreter. I brought him a BASIC compiler from the computer
    lab, showed him how to clean up his code so it would compile, and let
    him have a go at it. His saturation models went from days to hours just
    by running compiled code instead of running it in an interpreter. After
    that I told him if he really wanted it to run fast learn to program in
    C+ and only include the math and display libraries.

    Back On Topic: Where (generally) are you located? If you can't make
    what you want yourself ultimately you will probably have to have
    somebody make it for you. Yes, unpack the darned thing all freaking
    ready. LOL.

    There are creative solutions as well. Maybe, find little doodads that
    are shapes you want that might hold up for a few runs. Screw them to a
    ring. Slide the ring over a drum. Lots of mechanical details there to
    work out, but there are tons of steel stamps out there used for various projects in leather,metal, etc you could just buy, and cut the pattern
    off the end to screw/solder/welder/glue to a roller.

    You might even be able to use hard wood patterns for short runs.

    An idea too. However ... both of us are looking for a pattern we

    Ya reckon maybe if I unpack it, that would help?

    I think there are two approaches I might consider.

    One is a single roller for embossing your detail, and a second roller
    made of a hard rubber or foam that gives just enough to allow your
    pattern to be imprinted.

    I realized that whatever pattern I come up with, I'm going to have
    to reverse it on what ever I use. Conceptually, I want to take a thin
    strip and "impress" a pattern of "raised" shapes (stars, half moons,
    squares, circles, etc). As I think about it, I could just roll the
    strip of brass thin, then hammer the patterns into the strip by hand, standard sheet metal kind of work.
    "But I'm a machinist ... "

    My other thought would certainly be more expensive and have design and
    material thickness limitations so I'll dismiss it for now.

    "It's a simple procedure involving lasers ..."


    Actually A local "maker" I know was showed off some sheet metal
    impressions he was doing when I visited his shop. He laid the sheet
    over over a pattern with foam block and a hard backer over the top. He
    was doing them on a simple hand operated hydraulic press. Impressions
    of coins, and various other hard patterns. More as proof of concept
    than anything else. H had some wrinkling around the impressions, but I
    think that was more a function of using patterns not designed to deal
    with that.

    Two matching rollers was my other thought, but you do have to plan for
    material thickness that way. Not just top and bottom, but also on the
    slopes and sides.... but lasers are good too.

    There's a long way to go from "this would be cool" to "and that's

    Further details on this project:

    I have it apart in a box for later "fixing". At a minimum, wire
    brush everything, and replace the bearing (needle rollers). It
    appears to be Uncle Bob's home built gizmo for rolling out stock, as
    it has a fitting to ratchet the gears. Could even have had an
    electric motor.

    This morning I realized a small issue: the gears are held on by
    set screws. Meaning that there is a missing tooth on both gears. As
    long as I go slow it won't be a great problem, but ... "it offends my professional standards." "Not set screws! Key ways!"
    But between putting in key ways and possibly making new gears (and attendant design, machine and shop time), and replacing the bearings,
    this is starting to look like more like "complete over haul" than a
    "quick" fix. It might be worth the money to get a second hand mill
    (is such a thing is possible?)

    Greetings

    I have a small bench top rolling mill. Works fine as long as I
    don't over do it.
    But, the rollers are flat. I'd like to put a custom pattern (or
    two) on thin brass / copper stock which will require something.
    Option A is to punch the pattern into a piece of flat steel and
    roll it through. Not a bad idea, but kind of limited to lengths of
    out put. (Some of this will be for decorating wooden boxes).
    Plan B would be to put the pattern into a roller so I can just
    crank out as many feet as I have material. "It will all get used
    sometime."
    The issue for custom rollers is of course, what is the best grade
    of steel for the rollers, and heat treating it after engraving. (Hmmm
    'I just had an idea forming in my brain...')

    The rollers are going to be about 2 to 3 inches long and about
    "this" diameter. (I really should unpack it and see what the actual
    sizes are...)

    Now, where I'm going to find the machine to do this is a complete
    second question.

    when he built the thing, so he went with it.

    Is your rolling mill home made? Is uncle Bob a stand back and hold my
    beer kind of guy?

    The smaller one I have may be an early Durston and I can't find any
    labels on it but I have found the same units online labelled Durston and
    it appears very well made. It's built up rather than the current ones
    which all seem to be cast. Here's a link to one https://www.worthpoint.com/worthopedia/durston-rolling-mill-used-vintage-1934480468
    , I think the construction is fairly self explanatory but then I have
    one so know what I'm looking at.

    I've been following this thread to see what people do or would do with
    rollers. So far I've been able to make the functional (not artistic) U
    shapes I need with conduit benders or cutting at angles and welding. I
    hardly ever use my HF Compact Bender or the rollers on my 3-in-1 sheet metal machine. It only made one section of stainless stove pipe from some scrap.

    What would you make with a ring or tubing roller?

    as this is about 2 1/2 wide rollers, not sure.

    I can see having a tube roller for making spiral tubing, say for a condenser / cooler tube. But ...

    -------------------

    Thanks, that is a good idea if you already have a tube roller, but not much justification to buy one. I'd turn a wooden coil form from firewood or use brake line bending pliers, perhaps with a screw tapped in one handle as a
    stop.

    I copied a long and complex replacement brake line in NiCopp using brake
    line pliers and was impressed with how easy it was. I think NiCopp is easier
    to properly double-lap flare than steel too.

    I've bent this type a couple times now using just my hands. Lines that
    run along the rear axle. It seems to be very, very forgiving and is
    more like bending stiff copper wire than tubing. Well worth the
    extra price for it which isn't that much more really :)

    I've bent less intricate lines by hand, less neatly. This one runs from
    front to rear of my truck along a frame rail and dodges many attachments
    with sharp corners that might collapse if bent by hand, wasting the finished section of the line. The pliers bend over grooved rolls.

    For high pressure tubing other than automotive brakes, Parker has the
    Ferulok system which is less uncertain than double-lap flaring. I used it to add hydraulics to my tractor.

    That line needed to be replaced too ;-)

    Along with another rear wheel cylinder, both front calipers, their
    hoses and lines leading to them... Plus numerous other things. I just
    sold the truck and told the guy about all its woes. But for rust I
    would still be driving it. Got tired of working on it for almost 40
    years...

    -------------------------

    Once I retired and no longer had to drive in bad weather the rust problems almost stopped. Spraying LPS-3 underneath helped some but it didn't
    withstand the high speed blast of salty water or protect enclosed areas I couldn't reach well enough. So far the 1991 Ranger still passes state inspection (yesterday) and the body is all steel, just not all original
    steel. My MIG welder repaid its cost plus night school tuition on the first job. The body shop estimate to fix a dime sized rust hole was $800, before painting. The dealer wanted $3000, probably to replace the whole panel.

    The inspector told me he was flat out busy because people are fixing their
    old cars instead of replacing them. I think I see why after test driving several. The new ones look nicer and have many fancy features (to break) but are less functional, my Ranger has a 7' bed that holds 4'x8' plywood or sheetrock with the tailgate tied half way up via a convenient notch. It
    takes strong roof racks that clamp into the rain gutters and effectively
    extend my ladder rack over the cab to carry 12' corrugated panels and 16' lumber and steel. My neighbors' high-end full sized trucks can't do that.

    I signed up for two night school auto repair courses in April. Like the
    truck my knowledge is 30 years out of date.

    I signed up for two night school auto repair courses in April. Like the
    truck my knowledge is 30 years out of date.

    I can do the rust work, mechanical, electrical... but it needs to be
    +60 deg for my fingers to work. In the winter time I have the time and
    tools. I don't have an open garage that is warm enough to work in :(

    I replaced it with a 2013 Chevy Impala LS. Actually like it a whole lot
    better than I originally thought I would. Next model up has a fold down
    rear seat back... but a couple bolts and some wrestling gets the rear
    seat back out. Was able shove a 10 foot stick of 1-1/4" EMT through the
    trunk and up past the tranny shift and still close the lid ;-) Trunk is
    pretty roomy and so is the rear seat area.

    I drive less than 1000 miles now per year. Around three tanks of gas.
    This will likely be that last vehicle I own. They're just way too
    expensive to have around anymore...
