The Boxford 260VMC as you probably never seen it before!

is the original steel.??

Nope... It is a kind of aluminium alloy...

This is probably a bit far fetched, but I wonder if it would be possible to machine a thread on one of the cheap ballnuts from china? The grade of steel is clearly hard, but it does file so it may be possible to machine.

Hi Jonathan,
You would do that on a Lathe I guess. So would you first remove all the balls ?

Thanks for the link RNR, mine are steel and i would have opted for the repair but to be fair it really was fooked, i couldnt understand what was happening untill i had stripped everything down and by that time i had moved the Head up and down at least 20 times just to get it to go to the top so i could get the thing off... it was toast... i will replace all three with the threaded type like for like as i just dont have the time to mess around doing the other type with the machining..... I will let you know how i got on when its done but dont hold your breath as im building a gantry machine at the moment so it could be a while...
