Little update after a couple of months... I've got the FT-1S all set up. Here are the things I've done so far:
1. Installed a Teco E510 VFD + swapped out on/off/on switch with a smaller one to add room for a potentiometer for speed control
2. Installed a 3-axis TouchDRO-based DRO. Fabbing up scale and read head mounts was fun
3. Made my own way covers (Lagun wanted $1,500+)
4. 3D printed a spacer for the spindle bearing above the pulley. I had pulled this apart to clean it, but when I put it back together, it seemed to be crushing that top bearing, causing noise. I removed the 2x copper washers and 3D printed a 0.070" spacer to replace it - worked great!
I still have a few things left to do - like set up the tach on the TouchDRO, install a collet holder, etc but so far, this mill is working great! The lube pump has been working fine too as long as I don't use full strokes of the lever - been doing 1/2 strokes or so and not a single problem.
I have videos of some of this stuff, if anyone cares (and it isn't against policy to post links)... just let me know.
Thanks again for all your help!
