How I fitted a parallel acting split nut for the lathe #lathe


Thomas Janstrom
 

So first off a brief intro...

I first found Dave's books almost 30 years ago and started to build the lathe which took me near a year to finish but I got there. I built it out of bronze and stainless steel just because I could. However one thing that always annoyed me was the split nut. it's a fiddly wearing part that you end up replacing every now and again. For an extra two castings and some brazing you could have a nut that is much longer lived. So I finally bit the bullet and made it this year, almost 20 years to the day since finishing the project originally and at least 4 split nuts later lol.



Only made one tiny miscalculation which means until I file off the top a bit the tailstock wont advance as close to the carriage as it did previously.
