Keeping the head from turning on a cheap mill

<< < (5/5)

CrazyModder:
I fixed it, and it was dead simple: I just had to strip off the paint under the bolt head at the base. Obviously, the extremely thick layer of primer+paint would compress and thus loosen up ever so slightly under extreme circumstances. Since sanding the base completely clean there, I have not managed to turn the head during milling.

Arbalist:
 Pleased you've got it sorted!  :thumbup:

Hi.  I would give some consideration to filling the hollow column with epoxy and sand, then drilling the column for the cross pin.

CrazyModder:
Nah, the column is massive steel, I replaced the stock one before even starting it up once. ;)

Hi
Lots of ways to fix the problem posted here so I will add one more. Replace the clamp bolt for a one with a finer pitch thread this will give more closing pressure for the same amount of torque.
 The roller thrust bearing under the nut is a good addition.
 Keep the column clean
