Wayne,
There isn'y a point. There are any number of points!
Nothwithstanding the expertise of Myford, stiffness( I don't like the expression) can be because of
1. A worn bed. A classical situation some 6" or so from the chuck.
a, this can be worn not on the top as well as No1 shear.
b. it gives a rounded edge.
2. the saddle might be worn- using the inner guide principle.
a. it might have to convert to using the rear and probably unused No4 shear
b if the rear shear is worn- Cleeve was first to remark on this.
3. the leadscrew can be worn,
4 the feed screws can be worn.
5. the clasp nuts themselves might need re=scraping to p[revent binding. They are only Chinese metal
6. the bearings at each end of the leadscrew might be worn.
7.the gibs might be worn or bound with chips.
I think that 7 possible faults is enough. Otherwise, I might have to come out of 23 years retirement- but my charges will be a bloody sight more than a Myford fitter's. They always were.
Verb sab?
