Bench grinder question

[michael_schaap]

Would anyone know this about a bench griner.... I want to use one side of it to power a home made grinder (that uses sandpaper), however the arbor is only 1/2 inch... can I extend this arbor to spin the driver wheel?

did you think of making a sleeve that can go over the arbor,secured by a set screw,then an extension out the other end,again secured by a set screw,thats just 1 idea,you didn't mention the make,or type of grinder your using.

Michael,

If you mean that the arbor only extends 1/2" out from the motor then I would be inclined to say no. 1/2" of shaft isn't much to hold much side torc. I would look for another motor just to be on the safe side. Used bench grinders are much cheaper than doctor's bills.

I did decide to try that grinder.... $15 is $15 and if I cant get it to work as a belt grinder I'm sure it will be a very good bench grinder Eigher way, the process of knifemaking should get a tad easier.

I'll keep you folks posted

Grainger has a bunch of shaft couplers. I saw some which were a flexible type which give some compensation for misalignment.

their website is www.grainger.com

check part no. 2X497 or do a procuct search. they also have a pretty good selection of industrial equipment and prices are reasonable.
