I did a bit of an upgrade so I can drill and tap straight holes in the masts I build.
First I had to build an elevated, super-flat table for the entire machine.
Then I cut a hole in the waste board.Screwed some clamps into
place to hole the top of the mast.
Then underneath I added another board with a similar hole and clamps.
Now I can use my CNC machine to drill holes. The router bit I use isn't quite long enough, but its good enough for pilot holes I finish by hand.
And I can use a laser to align everything just right with the
clamps.
