Time for some upgrades. I got sick of being stuck with 1/4" tooling (lots of fun cutters- dovetail, keyseat, etc.- seem to start at 3/8" shank), so I got a spindle that takes ER16 collets. Now I can go up to 3/8" tooling! Same RPM and power specs, though.
There's also the new coolant system- more on that later. Basically a pressure regulator, reservoir, mixing block, and a nozzle. A quick test indicates it works really well. I'll be more excited once it's actually installed.
Maybe eventually I'll actually get back to building stuff instead of building stuff to build stuff...
