POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

This isn’t my best work, but I think it’s as good as I’ll do. I didn’t make this of course. But I did make it functional again. Ha!

Still messing with the tumbler. The worm drive gear motor I was going to use had a bad motor. I'm NOT rewinding that!

So, wanting to salvage the gear box, I pulled the motor and gearbox apart. Cleaned everything, and popped the rear cover of the motor open. Bored out that rear cover to take a bearing that I had on hand.

Then started working on the shaft. Had stripped the rotor off of it before the MN/WI trip, so started by turning it down where the rotor was (To true that up to the seal surface. Not sure why it wasn't true, but it was bent some. Then shortened the shaft, and turned to .600", and it part of it down to .5000". Next took a chunk of hot rolled, drilled and reamed to match the 1/2, Loctite 609, and a 1/8" cross pin pressed in. Reamed the cross pin about 3 tenths under, so needed the press and used some 609 also. That sucker isn't coming out!

Then threw the shaft back into the lathe, on the previously turned .600" diameter and trued it up. Then center drilled the extended shaft, cleaned up the hot rolled, and turned a stepped diameter 2-3 tenths over the bearing ID, with the lead in 5 tenths under.

And, I'm done for tonight. Will measure everything up again tomorrow sometime. Have to machine a flat on the extended 1/2" shaft and press the bearing in. Hopefully, if everything goes well, I'll have 1-1/4" of shaft extending past the end of the old motor housing. That can be coupled to a 1/3hp motor, and the gear box will be serviceable again.
 
Today, I continued with the band saw conversion. I don't have much on hand in the way of scrap that was going to be useful here. I had some scrap left over from some other thing long ago that was probably not 6061 (at least not T6) that amounted to some bits of 5mm sheet. So I squared and cut and layed out and drilled and tapped. It wasn't going perfect, but it was working out. I decided to just zap it with spray transfer MIG. It's a fast moving process that is easy once adapted to, but this was a one-shot, one kill with the settings. Worked out fantastically strong, but nicht so gut on the visuals. About what I expected. There was one problem, though. I was fumbling with my setup and getting the corner clamp set, and in the shuffle, I turned the base plate around and welded the wrong end. I'll start over tomorrow after I find another piece of material to use.

I'm guessing we have ALL done that kind of "learning process" over the years !

My personal favorite trick is to wire up a connector, with solder cup joints, beautifully soldered (like Michaelangelo quality), only to find I forget to put the cover or a grommet on the cable first...

One step back before taking 3 steps forward. I can't tell you how many times I've made a template, transferred the hole locations, drilled/machined, THEN realized I had the template back side up.

I'm really excited to see your conversion! I'm looking at the same motor kit for my Craftsman belt-drive drill press. I can't tell you how many 1/8" holes I've drilled in steel at 250 rpm's because I was too lazy to flip the belts for a speed change.
