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

I must admit I’m quite jealous you found the granite slab in the dumpster.
You must be a master dumpster diver.
Very nice looking machine.
Well done.

really nice, good dumpster diving, I make everything out of bed frame. I recently found a dual shaft 1 1/2HP motor with a 15in disk sander on it, really heavy and I was on my bike, so I stashed in the weeds. Runs strong, maybe a good project for the other shaft.

Impressive work good luck

Hi, well with the granite I went to a counter granite shop but have to go after hours cause they dont want you in dumpster cause might get hurt??? they dont want the granite just dont want injury, I can understand cause how alot of people are these days its sad sorta.

You be surprize how much I get from dumpsters, alot of wood from housing projects all the time, and get this, the factory close to me gets steel coils on skids, there 4×4 and two 2×4 all oak, [But lately I been getting them made out of Black walnut,YEP you red this correct black walnut, good not many nots at all I use these for my segment bowels, I put a hardwood floor in my hall and bedroom with this just some work cutting and router edges, I have a 12inch table saw helps ALOT!

Here a photo of my last vase made ALL out of scrap wood,Well have to start new post if you want can look at it there, Thanks

I too have been diving in a counter fabricator’s trash for several years now. Not only do I score granite or marble slabs (sink cut-outs mostly) but also Corian and Formica pieces too. The Corian or a derivative is great for making jigs and routing templates. I even made 6’8” and 7’ door butt templates for hanging doors from scraps out of the Corian. The stone and Formica pieces are good for when you need a flat surface to work on.

any chance to make one video using it ans showing more details?

a few months ago I try to make one like that using wood but the result are not good (maybe my fault)

Thanks for all the good comments, I must say there were a few cuss words during this but all in all was worth it.

tblank, sounds like you have a good thing going also, its something what some of these places throw away, if you can use your head one can come up with alot of good uses for them, thanks.

I forgot to take photo of a bearing I mounted on the back side of the disk so when one push hard the disk wont bend in much.[dont seem to anyways but insurence is best] I welded a 5/8 nut on a adjustable piece metal and put a bolt threw a bearing and tighen it down is all, seem to work .

I know when I first started to get idea of making this I looked alot on line of guys who have made them and got alot ideas, could not done it without that info.

I will get the boss [Cora] to help me make a video and I can explane more, she the expert on these computers I just turn them on use them about all.this week sometime.?

Hi, Heres some photo I just took for you, I used old rubber roller from boat trailer and put a bearing on the handle end cause it pulls on it there, works good very accurate when setting height Hope this helps?
