A couple of months ago I came to own a very nice, almost completely rebuilt Smart and Brown 1024 lathe. I've heard that they are regarded as highly as a Monarch 10EE, by those who know.
When I say "almost completely rebuilt" I mean that mechanically this machine is excellent. everything works as described and it has been converted to a VFD drive.
The work that has not been completed is the bed. The front slideway is worn about .005" and the carriage is also worn. It looks to me that the oiler may have stopped working at some point.
for reference here is the shape of the bed
The wear on the front slide about 10 inches to the left of the indicator in the first photo
The next two pictures show the markings on the bed. As usual it's hard to get good pictures...
I have tried to measure the areas where the marking is missing and I can't get a measurement on the .0005" indicator I'm using.
Now the question...
How to procede with the repair??
I thought I would;
1) scrape the flat ways, flat and straight ( very little scraping needed)
2) scrape the front way (the worn one) using the flats, and the tailstock V as reference
3) scrape the tailstock V straight and parallel with the front way.
4) scrape the carriage and align with Turcite.
5) I figure that there will be at least 012" of wear to make up for and I could scrape the turcite to allow the carriage to sit back in the correct alignment for gear and feed rod fit.
Any comments?
Is there a better way?
Thanks
Pete
