Hi,
working on a VN22LU saddle. The lower sub-saddle of the universal rides on the
knee top surface dovetail.
The casting itself has worn due to chips and lack of lubrication, and is about .005"
out across a diagonal, relative to the reference surface (original scraping of the
universal saddle's pivot joint).
Here's a picture of the underside face. Some scores which are an additional .004" low
as well.
Since I need to remove .030" or more from the knee anyway due to scoring there, I'll
have to build up the underside of the sub-saddle.
My question is: with turcite type products, should I mill out the .005" unevenness of
the saddle, then apply turcite?
Or, is it no problem to have turcite to .030" in some places, .035" in other places?
I suspect the answer is: turcite might compress by a very small amount, but this
level of unevenness is irrelevant, particularly on an old mill. But I wanted to check
while I am setup to mill the surface if I should. I will have to prep it for turcite
adhesion regardless...
Thanks!
