When I made my X axis one I kept having a problem with the two bolts not holding the nut mount tight enough and it would work loose causing backlash. For the nut mount, I used a couple of alignment pins and haven't had a problem since.
Hi Art,
I was thinking that there was not much "meat" on the mounting flanges and wondered whether it would be a problem.
How did you align the nut onto the saddle since it can't be adjusted once the table in put on. Is it a matter of tightening it so that there is a little movement, fit the table, get it aligned then remove the table and fully tighten the nut?
Then once it is all aligned, drill and insert the pins?
I am also considering having clearance holes in the saddle for mounting and threading the nut holder. That way, I could tighten the bolts from underneath.
The saddle would be mounted to the upside down table on a bench.
Cheers,
Peter
