My 72 x 2 Belt Sander

**garage nut** · Mar 30, 2018, 09:22 AM

Started my 72 x 2 Belt sander. I am not going to make knives, but I think it can be usefull for all the notching I have to do. The better the fit the easier and stronger the weld. I TIG all my suspension linkages.

I did not use square tubing because the fit of one tube into the other is too loose, so I machined down some 50 x 50 x 5 angle iron to give me a nice snug fit for the 38 x 38 x 4 square tubing I use to slide into the other manufactured tube. I inserted some 0.5mm spacers before welding up the angles to form the tube.

A friend of mine suggested I add some hinges so it is easy to flip it 90 Deg so the belt will run horizontally.

Ps I did have to rotate the footage through 90 Deg that meant 2 eddits as the software only allowed 45Deg at a time.

I took out all the horrible sound.. to make the file a small as possible.

And I added its name

Noe for some guards, paint and a proper switch

Unfortunately nothing in the design is my own, Copied basically 100% from a knife making site.

A lot is published on the wheels. I looked at AliExpress as well, sometimes I get stuff there for cheaper than what the material would cost me.

But I ended up with buying some 50Dia x 65 Ali for the rollers and 32 OD x 12 ID x 10 Wide bearings. Not going to bother turning shafts, just going to use capscrews with shanks long enough so the bearings will not sit on thread.

I also opted for an extra roller on the front plate. This will allow me to have both a back supported and unsupported section for immediate use. Remember I am not into knife making, so need to grind off burs and make rebates for welding. sharp edges on a solidly backed belt can rip it to shreds in no time.

Have you any drawing I’m thinking of making one & looking at a few different types. Will build it on my YouTube channel.

Finished....

Used the lawnmower's motor cover with a coat of paint designed for plastic.

Showed it to a friend of mine and he immediately commented that it does not have a "work area/table", fortunately he came up with a solution as well. He scrapped a commercial sanding disc machine, but kept the "working area/table" so....will be fitting this.
