Couple of recent projects

[Pacer]

Have wanted a tool post grinder for some time but wanted something small and easily mounted, but never saw anything I liked. Over time I had printed out articles and photos of various creations of home shoppers, but again, nothing 'hit' me. One problem was a small motor that would have the 'oomph' to do this. Had tried a couple (sewing machine motor) and they were way wimpy. I also wanted it to be mountable on the QCTP, so when I built the precision drill press, the motor I found at Surplus Center was such a winner that I decided it was time to move on this project. https://www.surpluscenter.com/item.asp?item=10-2519&catname=electric This little motor is a real jewel, runs on 110v and is easily made variable speed with a common dimmer switch - one minor draw back is it isnt easily reversible. On the little grinder is an old ceiling fan/light switch that I had in the junk drawer.
This is what I came up with...



Next, I have been working off and on rebuilding an Emco compact 10 lathe (another Katrina victim) for some time and the micrometer dials were unreadable - plus the round hand cranks were pitiful. So, I decided to make up completely new controls - new dials and some nice ball cranks (I've always had a weak spot for balanced cranks..)

After getting that done and turning out pretty well and still having the dividing head set up, I decided to finally convert the dials on my SB lathes cross slide and compound to read in "real time" - .001 instead of the factory reading of .002

Nice work, that TP grinder looks sweet.

I really like the grinder, One question why the drill chuck? A compression chuck would be smaller.

Your projects are a little out of my league for now. What is the trick to cutting such uniform balls in your crank handles?

Really a simple answer, Paul --- It was already in my extra parts drawer !! The spindle shaft is threaded so I have options.

Agarret, I'll try to gather up some pics of making up the handles/balls and the tool I use in another post.

Is there any issue with hanging that much weight on the QCTP? How much is steel, and how much is aluminum?

Very nice looking, though!

I seriously doubt it, it probably weighs only 4-5 lbs and since there is such small loads used in grinding - you can only take a thou or less - it shouldnt be a factor. Except for the two Al motor mount rings, the rest is out of scrap yard "unknonium" steel. The piece with the dovetail and the hole for the spindle is a solid 'hunk' The spindle started out as a piece of DOM tubing.

Thanks for the answer I ordered one of the motors. Going to try my hand at building one.

I ordered a couple of the motors as well, looks like a great project.

Thanks for posting it.
