Thread: Reconditioning a Relmac lathe
Also a 1.25" reamer is about £70 which is way more than its going to cost to have the spindle reground...
I had a quote from a 'mobile line-boring' company who normally do much bigger jobs but it was silly money. If I had another working lathe and a milling machine I suppose I could make up a line-boring jig using 2 bearings supported on the cross-slide to hold a boring spindle with a small pulley to be driven from my 3phase VFD'd motor and using the tailstock centre to align it... but then if I had another lathe I could take a fine cut off the spindle, although getting an accuracy of 4 - 5thou over a 12" length would probably be tricky.

The spindle is going in to be reground tomorrow AM early and I hope to get it back next week. They reckon it'll be 2h work inc setup as they'll need to make a MT3 arbour to hold the nose end and chamber the inside of the tail end to hold it on the grinder centres - they do all precision grinding between centres.
So this weekend I'll turn my attention to the Gamages lathe and get that set up on a board so I can try it out. At least the motor is running!

Got my spindle back :)
Cost much less than expected cos they did it as a 'homer' for cash as a favour and not through the books. All nice and shiney and smooooooooth :) and good within .0002 thou (well much tighter than I can measure anyway)
So weather permitting its 'pouring time' again this weekend!
BTW, anyone got a mill I could get access to, as I'm not likely to get a milling setip working any time soon (apart from the lack of space!)

What about one of these:
B'n'Q sell one like it for around £50, this one i use and it seems to be the best i have seen for that price range, or do you need a proper "Mill" ?
The spindle looks sweet mate, cant wait to see what this weekend has to offer !
A proper mill - something that'll take a couple of cubic inches out of a casting in a relatively short space of time...
It could wait till I get the 'big' lathe running...
Didnt think B&Q sold milling machines, nothing on their website and cant say I've ever seen them. I've got a cheap pillar drill from B&Q - bought in the sale a couple of years back, reduced from £75 to £15 last one and with a damaged box but its not exactly a solid bit of engineering, struggles with 6mm into cast iron or 8mm into steel.... but hey, the drill bits cost more than the drill!
Any advancments ?
