This guy clearly did all this "because he could" ... and had fun doing it! He probably spent 10 times the cost of the drill press pimping it out. A good presentation.
One thing he didn't do (or didn't show) was cleaning out the tapping chips in the casting after threading to mount the lift motor. Also, I'd go for vacuuming up the chips and sawdust rather than blowing them all over the shop. (A friend made a "swarf slurper" from plumbing parts that attached a shop vac hose to his mill to do that:
)
I don't have 3D printing or CNC. In fact, having just moved I don't even have a working lathe until I rewire my new shop, which likely won't be done before late spring. I did do something like all this ("because I could") but much simpler:
Variable speed & reversible using a tread mill motor and RPM read out.
Table lift/lower using a motor from a paper shredder and chain drive to the lift crank. (His way was much better, but mine cost $0 of scavenged parts).
Still lock the table manually, but with cam-activated micro switches so that I can't run both the drill motor and the lift motor at the same time.
I like the mag base vise idea, but the variable speed is the most useful.
