(Merged two topics on these spindles)
I’m looking forward to playing w/ it myself!
A test fit of the mounting plate went well save for the two M5 holes which I had to open up w/ a #8 index drill (hence the adjusted file above).
Decided that the best option for a finish would be spray paint, so swung by a big box store on the way home and picked up a can of
as the most expedient finishing option — eased the edges w/ a file, and deburred the holes w/ a countersink bit and scrubbed the plate down w/ a Scotch Brite pad, then wiped off w/ rubbing alcohol to degrease it, so hopefully it will take a couple of coats of paint well tomorrow.
EDIT: One further concern — the mounting plate I made is ~6.6mm thick (probably 6.35mm now that I think on it) — the next thickness up I have is ~13mm thick (probably 12.7mm, 1/2") — should I make one that thick? Trying to decide if I’d want the added overhang cutting depth… would the added rigidity merit the weight/increase of lever effects? The plate is ~121mm tall, and the distance from the center of the lowest of the upper bolt points to the center of the uppermost of the lower bolt points is 14mm — worried that I’m going to recreate the chatter effects of the initial Shapeoko 3 Z-axis spindle carriage plate.
