That was a brilliant build to watch, guys. I thought they were bench top rolls till I saw the rollers on the floor, lol. I like the way you split one side to remove the workpiece. Great design to copy and scale down. Thanks for that. Tony
Exactly what I thought. I'm willing to bet off camera they said "oh fuck" when they slid the sprocket on first then the pillow block bearing and realized they should have made their base frame three inches wider lol 🤣🤣🤣🤣
What are the outside diameters of the rollers and the wall thickness of the rollers. ? Why did u decide to make very large rollers? I noticed that u were gringing down the rollers and measuring with a square for straightness. Did the rollers slighly warp or bend when u rolled that first piece of thick sheet? What is the maximum thickness of sheet that u can roll without warping the rollers?
Hey James, outside diameter is 11.5" the wall thickness is 1" the shaft size is 2.875" solid. We used these rollers off a old conveyor system because we got them from a local scrap yard for cheap, we then had to fix any dents of scratches on the surface of them and fill any low spots on them. We have only ran .375" material in the roller and it works great. Most of the time we use it for .125" stainless. This whole build was done for as cheap as possible. There is many things to improve in the future. We got in a hurry and need to finish it quick for a job at the time. I hope to revisit the build and improve in the future. We made many shortcuts with this project unfortunately lol....but its just metal easy to cut apart and glue back together.
Bigger is better right? Lol. We have plans on adding hydraulic cylinders to it still. The cylinders will help apply downward pressure to the top roller.
