I graduated from Texas A & M in 1979. I took two Engineering Technology classes my senior year that resulted in this:

Another class did all the sand castings, which I did not take. The first class I took we machined all the rough castings to spec. The second class we machined all the rest of the parts, the rack, cut the teeth, made the gear, handle, everything. Only off the shelf parts are the Jacobs Chuck, a locking set collar and a flat needle bearing set.
Here are close ups off the head casting:


I first had an old washing machine motor on it but then around 1982 I acquired this variable speed DC motor which still works great:

Then I added an air powered cylinder (the black tube) which will move a cable up and down. The cable is attached to the drill table and is flexible enough I can move the table left or right easily. I can open the small up and down valves and control the air with the black actuator on the stand to raise or lower the table without having to fight it.

So needless to say I have been using it all my life reliably and proudly. I could not find any examples here at the Garage Journal so I thought I would document it in case anyone is interested or ever goes looking for one. I found a few examples on Google but they were different with a weird double pulley at the top and a long belt to the motor mounted at the bottom, and no names on the head casting, just an attached badge. Sadly I could find no reference to the classes I took in the current course catalog at TAMU.
