    I need to make a Slip Roll Machine.
    The kind that usually roll sheet metal, into circles.

    However, My material is (#9), 3/4"- Flat Expanded.... (3/4" carbon steel grate).
    I need to roll 16" circles, out of 9" wide pieces.

    All the retail machines are "20ga max".... Unless I spend $6k. :doah:


    Is it possible to make a Slip Roll Machine, that rolls #9 flat expanded?
    Can any of you machinists point me in the right direction? :dunno:
    I cant imagine that a 12" capacity roller, that rolls a 16" diameter circle, is too hard.



    Thanks in advance.

    Can't help with building one, but there is a huge one at my buddies shop that would laugh at that #9 grate.
    If you can't get it done locally I'm sure he could handle it for you. Not sure of the cost though.

    Yea... For my Fire Baskets.
    Ill need them done weekly.

    It'd be more cost-effective for me to build a Slip-Roll.
    The amount the Steel supplier wants, to roll grate, is ridiculous.

    Buy a used one.

    If you need measurements or some close up photos of the plate roll we have let me know.

    Thats the problem, tho....

    A used one that does 14ga is a couple grand, and usually 3-4 feet wide.
    I just need a 12" wide machine, with the same capability.

    Could you build a radius bender at the edge of a work bench and bend it a little at a time?
    It might not be a perfect circle but it would be cheap.

    Thats kinda what i'm doing, now.
    I have a homemade tool, that I use to make the bends.
    It does a damn good job, but a Slip Roll would make it much faster.

    Not to mention, safer.

    Agreed.... can you find a local place that can handle it yet still be cost affordable?
    I guess a lot of that would depend on the volume of parts you are getting made.

    I'd love to get my buddies shop to do it for you, but I think the shipping from San Diego would kill your profit margin.
    I can give you the e-mail address of the production manager if you can't get something done locally.

    I'll also keep an eye out for a used plate roll. Used machines from lathes, cnc mills to belt sanders roll through his shop every week and I get dibs on anything I want.

    I'd think a machine rated 20 gauge sheet would roll 9 gauge expanded with ease...

    Thanks. Appreciate it. :pimp:

    Shipping them from SD would prolly ruin it.
    But, a machine I can swing a trip for. :thumb:

    I think Ill just order a $200 Roller, and see if it explodes? :dunno: :haha:

    Ideally, Id like to own a machine.
    So, I can give my cousin-in-law a summer job.

    as the others mentioned, I don't think any machine will give you a prob.. as long as it's wide enough and you go in small increments......

    take a big sheet of expended, just as easy to bend that as sheetmetal, even if it is 1/8 thick...

    Lots of people have built their own, even some guys on Pirate, so how hard can it be...............

    This might give you some ideas.

    http://www.homemadetools.net/tag/slip-roller

    For production, you will want a fast way to adjust the rollers. Either a cam system or a hydraulic one. Such as a bottle jack.

    Screw down adjustments are fine for one-off, but not when you have to make a lot of pieces.

    Seems like you should be able to adapt some parts from a drivetrain.

    I'd just make a dedicated 12 1/2" wide rolling machine. I bet you could scab together a cheap rolling machine for that material.
