Got the prototype made for my latest project, a right angle attachment for the mill.
Yes the head tilts and I made a 5th axis but this is easier to deal with plus it can rotate around to the front also to use for slitting and especially for surface grinding like I did on my X2 back in the day.
Projects 4
I'll use rubber sheet to protect the mill from dust this time.
Waiting on stock to make it for real and do some testing.
Ground spiral bevel gears would be quieter but reusing the stock Z axis bevel gears appealed to the scrounger in me.
