Tailstock arbor for Warco Mini Lathe

I've recently bought a Warco mini lathe after having used a Unimat 3 for many years. I ordered a B16-MT2 tang arbor for the tailstock chuck without realising that the tailstock screw will interfere with the tang and the arbor really needs to be hollow – currently the only way to use the chuck is to wind the tailstock about 2 inches out before inserting the chuck, which makes the tailstock screw action almost completely redundant.

So, what sort of arbor should I have ordered? I've seen hollow arbors threaded for a drawbar but that isn't necessary in this case although I guess one might work if the tapped hole is oversize by a large enough amount. I haven't seen anything that looks like it's specifically designed for this purpose – or have I just not been looking hard enough?

Thanks in advance,

Chris

The problem with going for a hollow taper is that when you want to eject the arbor there will be nothing for the tailstock screw to push against. You can either use a threaded one and put a short length of studding in the thread or take an angle grinder and thinn cutting disk to the one you have and cut the tang off, thats what I did with the one for my Warco 280.

Thanks for that, Jason – sounds like a reasonable plan. Presumably you mean the short bit of studding is to give the screw something to push the arbor off with when it's fully retracted?

Yep, If you put a shallow saw cut in the end you can screw it out at a later date
