Well I tried cutting a 8tpi and it doesn't marry in with the gauge . I bought the gauges off eBay , I check my purchase history and the description says BSW & metric . . I'll try a 7tpi tomorrow and see . I only have a cheap calliper set but they seem to be ok ,I've check them against a Brown & Sharp micrometer .

I'm not sure,calipers are out in the shed and it's pissing down ,I've just downloaded a measuring app lol . Od of boss is 55mm or just over 2" ,thickness Id to od is about 10mm .

I'll take another reading in the morning of the thread . The back plate does have a boss of about 10-12mm .

Sean

I was thinking of getting a friend to do it . How would the part be held . Mark i think it's about 45 mm .

Sean

I wonder if the back plate can be made to suit the 1 3/4 8 thread

Sean

Thanks all

Sean

I was looking at the 200 mm version ,I'm unsure if it will be to big or not . My lathe 3 jaw measures 6.2 " Lathe has a 12" swing .

I shouldn't need a back plate with this should I ? I know nothing about chucks . I bought a set of thread gauges and measured the spindle threads , the gauges tell me that the threads are 7G 1/8-1/4 .

Anyone have/use one of these . I'm looking at one just and was wondering what the quality will be like .
