His videos are fun to watch regardless.

Well, I discovered one reason to run the strip sander in reverse. I was happily sharpening every chisel in sight and found that the hot sparks were melting a blister in my strip sander cover. See the photo below.

I decided to look at mounting a hub on the belt side, as described by Bill Mayo awhile ago. My shaft sticks out 0.31” so, not much to work with. I succeeded in drilling a 1/8” diameter hole through it using a long drill just clearing the drive wheels rim.

I drilled it without removing anything. I intended to put in a roll pin but went with a cotter pin for now. I made a new brass hub and made it short enough to not rub the cover when it is closed. It happens to be 0.629" thick.

I found that the strip sander does not line up when reversed, by about 3/16”, but the coupling seems to still work ok. With the cover open and the belt throwing stuff upwards, eye protection is certainly needed.

I also made a few improvements to the sharpening attachment. The knob to set the angle is now on the right, and much easier to use. I changed the socket that accepts the butt end of a chisel to allow bigger ones.

Peter,

Looks like you have discovered reason #2 for the sharpening platen.

The brass hub and socket are great additions, I see in the last photo you do have access to a good sized metal lathe and must have a nice stash of brass stock.

I see a lot of 'original' 'adaptive' thinking that went into this 'project'.

Well done!(even if it ain't wood!:D)
