The little geared motor is unfortunately a non-goer, I wired it up this morning and ran it on the bench for 5 minutes and it was too hot to touch. Not going to risk it.
Following the wise advice from those on this forum, I swapped out the carbide end-mill for a HSS one of the same size, decreased DOC to .020" and cranked faster (in fact I cranked from the main shaft instead of from the reduction drive, cranking much slower but turning the RT much faster). Making progress, I've got .500" to go to reach depth, plus say .050 for some clearance under the T-slot cutter, not to mention the same number of passes again on each side of the slot to bring it out to full width. Good news is each lap is now taking six minutes.
Tomorrow is Monday for me, and my days off next week are not looking favourable for time on this. I'm going to be sweating on that T-slot until it's done.
