My project today was stupid simple but the result will be a huge improvement in efficiency.
I needed to drill a 3/16" hole in the end of 4 pins 1.5" deep. Then drill 0.080" deep with 1/4", then drill #3 to 0.260" from the face. Then lightly debur the hole and tap 1/4-28.
My tiny headstock has to be locked down to loosen the chuck quickly. I had the center drill in its own 2mt, I chucked all three drills, the chamfer tool, and the spring tap guide.
The finish was to cut an external radial groove at 1.375" from the face and then drill a hole through the groove to the center hole.
What struck me is how much time I wasted on the drill chuck. On this lathe, popping out the mt2 is way faster than cranking the chuck on 5 different size tools.
I ordered a mt2 endmill holder in 1/4 and 3/8 for my chamfer tools, a 1/2" for my tap guides, and a mt2 to 3/8-24 drill arbor for an inexpensive USA made 1/2" Jacob's chuck.
I will have 3 drill chucks and my center drill, chamfer tools, and my tap guides will all be on their own tapers. This would have dramatically sped up my super easy job today. I blew around $100 on better efficiency.
Does anyone else find that changing tapers is faster than spinning the chuck, especially over large size differences?
