It looks very nice from where you were standing, but surely your not going to tease with just the one pic and not give a few more details.
Yeah details, how did you make the rolls are they solid round, bearing size and some detail on the ways for the top roll!!!

Thanks,
Ron

Hey guys, thanks for the comments and keep the suggestions coming, we're still hacking at it. We didn't get a chance to play with it today(dang it, had to work) but maybe tomorrow....rmack,you were close on the r.p.m. We timed it at 36rpm and then figured a travel rate(f.p.s.) on the rolls and extrapolated our ratio from that. The rolls turn at about 25rpm and a 10' piece will go through in about 15 seconds.--cutter,we didnt try any circles and I'm not really sure if it would work.The first 6" is still straight after rolling and it wont engage the other side when it comes around.But we can roll two pcs at the same time and weld half circles together.---Shade Tree, the rolls are 4" double wall pipe with 1.5" cold rolled shaft very carefully centered on the end plate. Out of six the worst one had a runout of about 30 thou.The bearings have been around the shop for years, thats why we used them.We used the T.L.A.R. system to determine the stand off on the plates(you know,"that looks about right")and then added side plates to keep it centered.Thats 1" all thread with a couple of pinched nuts tacked on, sandwiching the bearing plate---Mr. Zachman, we are pretty primative sometimes and a little brutal other times. All we did to dump was to tilt the lift full foward and then ram the pile. Thats most of a sheet of 1/4" plate and its clamped to the back of the forks with some good clamps. Never came loose once but did drag the ground a little when scooping. It worked good.--Hey all, thanks for looking-----Tim

You will never get a roll without the flat ends witha three-roll machine. Even a four roll will make you work to get it perfect. Sometimes I think I am deprived in some weird way because youse guys are making all this wonderful stuff on your own and I get forced to use high-end cnc crap that has no character.

Cutter,

This roller is similar to mine except mine is powered by a 24" hand wheel and I use a bottle jack to apply pressure to the center roller from underneath the machine. This makes adjustments to your arch quick any easy.

To answer your question about rolling a complete circle, I have rolled several. It's kind of a PITA. You have to account for about three inches of flat spot on each side. As your circle becomes almost complete, you have to cut one of the flat spots off so it will roll under the center roller and complete the circle. Then release the pressure and manipulate it over the center roller. This will tweak it a bit, but it's easy to bend it back to a flat circle. Then cut the other flat spot off and weld it together.

Thanks, Matt.
That's about how I envisioned it. But IIRC, someone posted a smaller handwheel type that was
designed with a (fairly) easily removeable top roller.

TEK, I Have always heard that after you build something once the next one you build would be much better. My suggestion is go ahead and start on the new one and I will guarantee you that it will like it more. By the way, since you are not using the other one any more how about sending it my way

Think of the floor space that will free up?? You're so kind to take obsolete equipment out of people's way, Slim.
