Looking to replace the tailstock (Proxxon PD400), need something more rigid

Hi Diagnosticated
Your friends might have been thinking more of the Proxxon PD 230/240, which has similarities to the Toyo. The PD400 is something of a different animal, with a headstock, gearing, and cross slide that is competitive with, say, the Myford ML7 which my friend has. But the tailstock of the PD400 is where Proxxon cut their costs... Photos attached, showing that it is a simple casting. It clamps to the bed well enough, but has no other adjustments to align with the headstock... I would like to hear if anyone knows of an after-market replacement! I understand that I can ream it, sleeve it, or make my own (!), but I really just want to hear about the possibilities of replacing it. Thanks!

Lester, you just aren't going to find a drop in replacement. The odds are these things are machined with the headstock on the same setting. A replacement from Proxxon won't be inline if they supplied them, and that probably accounts for them not being a replacement item. The centre height of your machine is going to be unique. Fabricating your own tailstock and machining it using your headstock is the only way to guarantee it will line up correctly. You do have some adjustment screws on the side, however you really need a between centres bar (accurately machined) that you can put between centres on your machine and clock it at each end and along its length.
:palm: The side screws will be the anti rotation for the tailstock.... Oh well...

That tailstock looks identical to the Toyo tailstock. Except toyo/manix use plastic handles which are not nice. I bet the toyo tailstock will fit your lathe. The toyo is now made by manix in Korea but it doesn't help you as spares are almost impossible to source. I just bought a boxford lathe because my Toyo small lathe struggles too much with bigger drilling, larger diameter turning.
