    Schaublin 135 cross slide has gone bananas

    Yes, that's true. But as said, I was able to verify the top measurements with the sliding surface ones .. A 0.05 mm feeler gauge was going under the cross slide very close to where it was 0.05 high measured from the top. I might do a bluing to see where the current contact is.. but based on how...

    Schaublin 135 cross slide has gone bananas

    Thanks for the input. In its original shape, it would've required grinding both the top and bottom, probably milling deeper dovetails, grinding the cross slide nut for fit (it's already very close to the cross slide bottom), making or buying a new gib and scrape everything into final fit ...

    Schaublin 135 cross slide has gone bananas

    Tables with t-slots for workholding and vises can indeed deform the table when tightened, introducing stress.

    Schaublin 135 cross slide has gone bananas

    The inability to directly measure internal stress in a workshop is a concern. Without concrete measurements, determining when stress is fully relieved is guesswork. Heat treatment stands out as a method offering some predictability in stress relief, contrasting with other techniques that seem...

    Schaublin 135 cross slide has gone bananas

    Seeing the effort needed to tweak this part, I'm convinced that regular use wouldn't bend it out of shape. There's no sign of any big knocks or damage on the machine either. Grinding it down to flatness would mean shaving off a lot, and who's to say it wouldn't just warp again due to material...

    Schaublin 135 cross slide has gone bananas

    Yes, it had a bow. It's back closer to its initial shape now.

    Schaublin 135 cross slide has gone bananas

    Thanks for the responses. Initially, I was pretty skeptical about taking "???"'s suggestion seriously, given we're talking about cast iron here. But curiosity got the better of me, and after a deep dive online, I stumbled upon methods used for straightening warped engine blocks. The idea of...

    Schaublin 135 cross slide has gone bananas

    Hello fellow machinists, I've encountered an issue with my Schaublin 135 lathe where the cross slide appears to be bowed/warped. The warp is approximately 0.08 mm high in the middle. This is measured on a surface table, not while on machine with the gib and nut installed. This is not due to...

    Cold Saw Blade vibrations.

    A couple old threads are on this forum with cold saws vibrating horrendously. I've read them all and not a single one provided any good outcome. BTW. I too hate reading threads that leaves the reader hanging. I had two saws which vibrated, a larger Thomas 350 and a smaller 250. The smaller was...

    Deckel FP4 manual mill / newbie with simple questions

    Thanks Ross for the thorough answer. I will check your project next. Good news is I've got pretty much figured out what you mention. What I immediately understood I need to have is: - Good known straight edge; I acquired a 1000 mm (pretty close to 36") triangular straightedge DIN 0 (I guess...

    Deckel FP4 manual mill / newbie with simple questions

    I'd like to share my future plans on this machine. Old thread but will probably open a project thread if people are interested. Please let me know. The machine has pretty much been idle since I acquired it. I've found out since then that spindle taper was worn after all these years of using...

    Why scrape when you can grind?

    I was about to write this. Richard King has written about this problem earlier.

    Vice Riser or long Endmill / Collet holder for milling

    Haven't been on PM for a while, but this thread just pushed the right buttons. When someone considers being a professional among professionals who don't have time to answer questions but still spend their "valuable" time on forums, it just makes me wonder what they actually do for a living...

    Deckel FP4 manual mill / newbie with simple questions

    Hello all, I used to read and attend other forum discussion earlier in my life. However, it soon became too much of a pain with cocky persons and other people just ruining a perfectly good thread. So, here we go again. This is my first post here and might be a long one. For those who want to...
