Todays Project - What did you do today?
The lathe is imported by Summit Machine Tools from Poland as far as I know Ken. Its all metric except for the lead screws to give imperial dials. The fine thread to adjust the preload on the thrust bearings is 1 mm pitch.
Will give straightening it a try Steve but it would have to be real close as the bearing that supports the shaft is a couple of inches long as is the block that holds the two halves of the nut, not much wiggle room.
Free advice is worth exactly what you payed for it.

Gee, that's a rough thing to happen, but as others said, glad it wasn't you that was hit. I know it's a pain to make or fix parts for something you need "right now" but it's an education to see your builds. Just too bad it isn't what you want to be doing right now.

Whittled out the housing for the nuts. Still need to locate a couple of holes for the ratchet system on the adjustable half and dowel pins to lock the fixed half of the nut.

That was fast!

Now what would it take to get that 1960's technology 2-flute 1" milling cutter (and I use the term loosely) with the TPG inserts out of your machine and get you into something that doesn't hammer your spindle?

Cost Ken Cost. Would be nice to have newer technology but it comes with a hefty price tag. The inserts for these are dirt cheap (even in Canada) and do what I need, mostly rough work. Actually this cutter got put in when one of the screws twisted off in my 1 1/4 - R8 shank Polish cutter. Doubt if its worth tracking down the odd headed left hand thread screws it uses, will probably get another tool, that one owes me nothing.

I understand that. I keep my eyes on eBay (have "saved search") and get killer deals on quality tools. What I've found is that the newer insert milling cutters have such better grades and geometry that you don't need "dirt cheap" inserts because they just last so much longer. I have indexed the 8-corner hexagonal inserts in my 2" & 3" face mills ONCE in the past year. Got six edges left.

Whatever works for you is best, and I do recognize that things are much different in Canuckistan.

Greg,

Ditto on the nice work.  I have run exactly one Polish lathe that was re-badged by a Miami machine tool dealer.  It was a very good machine and at the time costing much less than one from China that did not have near the capacity or ability to hold tolerances.

Most especially glad you were not injured.

installed the parts that Ken (aka Pixman) made for me.

heres a shot of them on the rifle that I've been tinkering with for the last couple of months. Still got a ways to go before I can prove it works.
