A few pictures of the small mill drill that I made for working on shall stuff rather that using the big mill drill. The drill was basically cobbled together using odd bits of metal and then a purchased surplus 9v dc motor and three dial gauges. The very first iteration evolved over a few weeks as I determined what needed improving as I used it. it began as just a drill press.
I realized that it would be better with an X Y table so set about putting one together with material I had to hand. as you can see i also changed the quill to a square sliding one, with a collet that will hold either 3/32 shank drills or 1/8th shank drills or mills.
I used the dremel collets in my own holder.
once the milling operation became an evident possibility the quill needed to be able to be adjusted in the same way as the table, so some additional work was done to allow for this. by modifying the feed screw length adding a gear and a worm, also a way to lock it in place.
Next another dial indicator to measure the feed.
This pretty much sums it up, I did not work from drawings but just basically made quick scribbles on scraps of paper as needed to make the nexr bit depending on what material I had to work with.
Its a handy little tool.
