Re: Y-axis gib...ugh
- I just wanted to follow up on this a bit.
As was suggested (thanks!), my gib was rising up as the screws were
turned in. I couldn't get good pictures to post, but I can tell you
that it was surprising to watch it happen from the edge of the saddle.
I wound up making a jig out of hollowed out gib screw (actually, I
threaded a piece of 12L14 and reamed for 5/32"). And using that, while
holding the saddle down and against the dovetail, I drilled new dimples
in the gib. I also rounded over the ends of the gib screws. This
works really well.
There's a barely detectable amount of gib lift when tightening the
screws and still a little bit of slop, but some lapping should take
care of it. I'll probably wind up making a new gib out of brass at some
