My 72 x 2 Belt Sander

[garage nut]

So I finished off the small rollers. You can see by the amount of thread protruding that I used bolts long enough so to ensure the bearings are sitting on the solid shank.

The next was the drive roller. Before I could machine it I had to decide what motor I was going to use. I have an old 1hp motor that has been lying in the shelf for years, but as I connected it to power to see if it is still running...I was reminded why it is on the shelf...It has a power leak from one of its windings...so I got a good old shock...back onto the shelf with a note on a piece of masking tape to have it rewired.

The next was an old central fugal water pump, but the motor was only 0.25Kw so too small.

Then I remembered a post I red where the guy used a lawnmower engine. I has an old (very tired chassis and grass box) electric mower but the motor is still good.

Upon inspection it turned out to be a 2.2Kw motor and it runs at 2880 RPM. A added bonus was that the method to attach the blade(bolt into the center of the axis) would be perfect for my 4' x 60mm wide drive pulley. I had no idea how I was going to tap a M8 through the 4' pulley (the conventional way to attach a pulley with a grub screw to a shaft). I think my tap is about 1.25' long.
