Hello All, Hope I posted this correct its for wood working I made most of it from steel channel I got from dumpster. I hope this info can help some of you like me to build a drum-disk sander, I cant efford to buy one. I got most all material from dumpsters and only bought pillow bearings,sandpaper[hook&loop,used motor 2HP-220,and pully and belt, Totel $160.00 This all took me 3 weeks and some hit and miss with making things. It is 20 inch wide with 5inch drum and the disk ended up being 19 inch round. made drum from 5inch mdf with a pin drilled threw the 1 1/2inch shaft[dumpster] I used my wood lathe for a metal lathe to check shaft for true and drilled both ends for 5/8 tap and threaded them one for pully other for disk. I use one 10inch and one 12inch saw blade weld together and a 4inch by1/8 plate to mount the 3/4 birch plywood disk on and made a 5/16 coller with bolt to lock disk on shaft. I got a 20×36inch piece of granite is 1 1/4 thick glued to 3/4 plywood for the table. If you can see the mechanism under the table to raise and lower the heavy table its from a boat trailor rubber wheels with a 5/8 threaded shaft with a bearing on the handle end it works great and stays where i put it. The motor is Balder 2Hp got it for $40 guy thought it was no good, He had it wired for 220 but was running it on 110 so only has 25% of rated HP,I hooked up to 220 has all power to run the drums. It turns 3400RPm I put a 4inch on top and 2inch pully on motor came up with 1360RPM which seems to be working good. The table for disk can tilt to 45 degrees but I messed up, I put the pivet center with disk which is good but had it 1 1/2inch down from top so when tilted it comes out from the disk???? So instead of redoing all this I made the table so I can slide it up when tilted[alot easier to do] I also put 5/8 bolts on the legs to level it cause it is heavy and I new I could not cut up and weld them all straight. Also it good idea to make up different pieces of wood for pushers to when you put round or smaller things in drum they dont come back at you, I am very happy with this so far.
Hope this can help someone and I be happy to answer anything you may want to know about this, Thanks for looking
