I have ordered a 4 jaw chuck (125mm) to use on my 102 so now I need to find a thread-on backing plate I can machine, fit and bolt the chuck to. This is schaublin so I know it isn't going to be simple:) The only option I can find online is from RC-machines in Luxemburg for around 90 Euro+shipping, taxes and fees to Norway which may be my best bet but the total cost stings a bit for a boring chunk of metal that probably isn't all that high quality and lacks a clamp to allow reverse operation. I probably have to buy one or have one made as I can't cut threads on my lathe yet (CNC is coming along but isn't there yet)

Am I missing anything out there?

There are a couple more options. I have some blank W20 arbors so I could shrink fit a plate onto one of those, true it up and use that, at least temperarily to work with the 4 jaw. I would like to have the spindle bore open so it isn't a good long term option.
I could also wait until I get my CNC lathe running and then make my own back plate.

thanks

Hi, caspaincmonster, I got in fact 2 backing plates from RC machines for my very old Schaublin 102VM. One for the 4 jaw chuck and one for the general purpose faceplate. They are for me good value for money. Fixing on the spindle nose is done with a M8 radial bolt. That is fine if you put a small brass prop at the spindle-end of the hole. I try to cut down on shipping by assembling a larger order from RC Machines. If you have for instance the older irregular Schaublin 2 degree center, RC Machines may be your only reliable source. Missing gears are a problem; I try to solve it by cutting them myself. To that end I bought a cheap set of Module 1,25 gear cutters for about 100 euro and I cut the gears from Delrin. I'm not sure what the stability of your CNC lathe will be, but I know from hard won experience that commands even be they numerical do not count for much if you don't have a sturdy structure to execute. So, all the best and let us know what you decided to do! Peter.
 
I have only just seen this, so excuses for my lateness. Purely by chance I have 2 genuine Schaublin 102 backing plates with locking rings that you are welcome to for a low price, say AU$50 for the 2, plus postage from Australia, that may be the killer!! Let me know if you are still looking!

Thanks Bill, that would have been great but I am going to probably sell the schaublin. I just took delivery of a 1984 Leinen MLZ with yet another spindle mount :) this one is at least just a taper without threads so it is much easier to make and can't unscrew. I ended up with a used schaublin plate for too much money from Switzerland and one that doesn't fit from a guy in the Czech republic.
