Lathe Cross Feed Screw and Nut

Impeccable write up and pics Doug. Seen a lot of this being done on YT and various places and this is by far the best of them. Workin that tiny .125 bit and the broach is off the charts, on top of all the ops! Thanks Always for sharing your great work and thinking processes.

Thanks You Very Much Mr. PJs for your encouraging comments, I was wondering if I was going to be able to pull off the 1/8" broaching, but it only had to go through 3/8" of steal, with a .147" hole to start with before broaching which relieved a lot pressure on the little broach, worked great though

Thanks Buddy

Thanks for your compliments Frank
a lot of bronze nuts are easily repaired like you say and have done, but if you noticed how thin of a wall was on the old nut I had it would have been nearly impossible to split it and deform it, I really wasn't looking forward to all the extremities I went through to make the nut but it did come out well, hopefully I want have to ever make another one.
Thanks Again Frank

Yes I noticed that yours like so many lathes do not easily lend themselves to having a nut that can be adjusted .
Also some lathes came factory with an adjustable nut.
I've ran lathes that were so badly worn from age that even if they did have an adjustable cross feed nut it would not have done any good because like yours the screw was also badly worn that the only way to get any tightness at all would be to set the compound (top slide) to "0" then run it all the way to one extreme or the other in hopes of being out of the wear zone.
Badly worn half nuts and lead screws are another issue that is often difficult to work around. there are a lot of shops where their machine tools are not part of their main business so the older well worn equipment is just fine for what they occasionally need a lathe or mill for. sometimes I would do some work at their place and need to machine this or that, I have mounted the 3 jaw in the 4 jaw or vice versa at times. just to get out of a badly worn area

without tools where wood we bee?? kinda like the chicken witch came first the chicken or the egg?? so witch came first the tool or the tool... as for the chicken conundrum... it wasent the chicken or the egg,,,it was the rooster that came first and a tool was used to make a tool....or was it? but just think. it we never progressed past a set of vice scrips.... what good would they be if there were no rounded off nuts to use them on. keep up the great work guys!!!!and always remember, every thing you do and post it helps somebody else figure out the issue they may be pulling hair from.
