My lathe had pretty poor mesh between the handwheel gear and the rack.
To address the problem I slid the rack about 1/2 inch to one side and moved the
rack down. Everything worked out pretty well. However, one hole is a bit too
high. I am thinking of a couple of ways to fix the problem.
1. Start over and drill/tap all of the holes again. Hoping not to do this, as its not
clear I will succeed the second time.
2. Elongate the through hole in the rack so that the screw will go in without distorting the
rack. The hole is off by about .030" and I believe there is probably enough metal
above the hole in the rack to fit. I am not sure what the rack is made of. It seems like
steel which I don't think is hardened. But I don't really like the idea of changing the
rack this way.
3. Fill the hole with JB Weld or some other sort of epoxy-like filler and then re-drill and
tap. I assume this wouldn't be as strong as drilling the holes in new locations (i.e., #1 above)
but I don't think this will be a concern. I haven't tried moving holes this way before so I am
not sure it will be easy to move the holes a small amount like this.
I would like to get some advice on what is the best way to correct this. Thanks.
