end holes





These parts are too long to CNC drill the end holes, so I had to make a drilling guide first.
I used a 3mm milling cutter to pocket and profile the shape in the Delrin, then I used the pillar drill and put the aluminium part in the portable vice and held the Delrin guide onto the end of the part to do the drilling. I only used the guide to drill a small depth, then I drilled them through later.
