Shootr's 2 x 48 Belt Grinder Build

admin

Now that I have the shaft of the buffer prepped, I'm starting to think about the design for the grinder.  Since it's been done 1000 times by others, there are plenty of pics and guides to work from.  This is the first iteration/idea using some luan.There will be a base of 3/8" plate that the buffer will bolt to.  A vertical plate of 1/4" will be welded and gusseted to the base and bolted to the buffer face.


I'll be using a 5" drive pulley, a 3" guide/tension pulley, and 2 - 2" idler pulleys.  I'll also make my own "D" plate/platen.   Got some heavy wall telescoping tubing to help with that.


The pulleys will be here next week, probably work on the platen tomorrow.Should be a hoot!Last edited by Shootr; 8 Hours Ago at 07:19 PM.Yeswelder MIG-205DS(3) Angle Grinders at the ReadyJust a hobbyist trying to improve
Reply:What do mean by "plug weld mounting bolts?" Hopefully you mean welding the backside of the bolts (with head cut off) flush in the holes. You need to get some better steel that isn't a rusted mess.

Reply:Are you planning on any stiffners on the upright plate? 1/4" isn't much for that. On the 2"x 48" upright I used 3/8" plate and if I was to do it over I would have used 1/2". I used a face mount motor but you will get deflection with that 1/4" plate even with the  flat base mount.
