I got this drill press last summer and cleaned it up, put in new bearings, and added a DC motor and controller setup. I've been real happy with it except for the way the table is adjusted. There is no rack or crank, just a column lock and "armstrong" adjuster.
Anyway, with the vise I've been using and any substantial part on the table, things get a little heavy for the one arm (the second works the lock.) So, in my best Rube Goldbergesque vision, this is what I've come up with.
I got this linear actuator off ebay pretty cheaply. It runs off 110v and has 13" of travel and around 200# capacity. I made a bottom mount which clamps off the column.
This is the top mount from the actuator to the bottom of the table. The setup can be disengaged by pulling the one pin.
Please tilt your monitor for the next 2 pics.
Here we are at the bottom of the travel range (there are limit switches top and bottom.)
This is at the top of travel.
I just have to finish up the wiring/switch mounting and splash on some paint. It works really great and I think my arms will appreciate it. Now if only I could get my kids to stop playing with it! Have fun! Sidegrinder.
I was working on putting up a short video but the lighting made it look like the innards of a coal mine somewhere.
