True. Should be a good test for rout planing and coolant systems.

Chain breakers put a substantial load on the threads. If using 6061, you may want to think about designing it for a Helicoil.

We've got some 7075 we're planning to use but if it's too tough to machine, helicoil is a good suggestion.

To run this on your Tormach, you will be using fairly small dia. end mills. To keep your chip load proper, this part will take a lot of time to process.

Very true.

This is a really good training exercize. It will teach you a lot about setting up and milling small parts.

That's good I hope they learn a lot.
