CNC newbie here. I am finally taking the plunge to make a gantry style CNC router, and having only typical home owner's tools, it needs to be simple and easy. I've come up with a concept that should work well, but it hinges on one little obstacle that I need to overcome:
I'll need to drill/bore 1/2" diameter holes through 6" of material, being 4" Delrin and 2 1" thick aluminum bar, all clamped together. If I can pull this off, final alignment with assembly will be easier.
Unfortunately my Delta bench drill press only has about 2" worth of stroke, so that won't work.
I have visons of taking the head off the drill press, or use my plunge router motor, clamping it sideways in a jig, and making a rube goldberg guide to advance the material onto the drill bit.
Any suggestions will be much appreciated
