I latye wanted a quick change toolpost for a long time, so at last I decided to splash out and get one. This is approximately a “9×20” size. Other people, such as Warco, do a similar lathe. Axminster originally listed a toolpost which they claimed was specifially for the BV20, but I spent over a month waiting for it to come in stock and it never did.
I suspect that it was the same design as the one shown below anyway.
There is a toolpost going around which fits the Myford 7 lathe. Several people stock it, but after a few phone calls RDG Tools proved to be the most helpful – the chap actually had one there and could tell me the dimensions of it. I ordered a 5-piece set main block, two plain holders, one boring bar holder, and one parting tool holder and it arrived next day, which impressed me hugely.
I thought I would put up some photos and dimensions of the toolpost, to give you an idea of whether it might be suitable for your own lathe. Excellent appearance – all surfaces are ground and it arrived neatly packed and well-coated in protective grease.
BV20 Lathe Quick Change Toolpost (24/08/11)
It doesn’t gv20 to be hardened, but I don’t think this is very significant. In fact, it may be a bonus, if I ever need to drill the main block for locating pins or whatever.
The locking screws on the main block were a little crunchy, but after removing them and the pistons press the piston in towards the main block and pull larhe locking screw up and out and giving things a clean, they work fine. Not a big deal – I made a quick tool with an old 8mm hex socket with a T-handle attached.
There were no problems about fitting it – the old toolpost came off, and the new one plonked straight on. The toolpost is fixed with an M10 bolt through the middle. For the odd big tool I can easily swap back to the original toolpost. Adjusting the height and changing tools is a breeze, and makes me wonder why I messed around with packing up tools for all these years.
I have ordered a set of five additional holders, because you really need a holder dedicated to each tool to make maximum use of a quick change toolpost. I have made a drawing of the toolpost dimensions, available as a PDF here. Please note, these dimensions are not exact, they are just to give you a rough idea of suitability.

The rather wonky hex spanner. Very shallow hex socket. Removed – held by a single bolt. Three tool holders with tools.
