If anyone is interested, I'm going to liquidate the 8" 4 jaw Kitagawa (made in Japan) from my Atlas, I have a 1 1/2 - 8 backing plate for it but I think it's too big for that spindle the chuck weighs in at just over 30 lbs I don't think it ever got used,(certainly not much) I disassembled it to clean and grease and there was virtually no swarf. I cannot find a reference to the model (9816) but the 8" plain back they make currently is almost 1800us so it should be of excellent quality It's tight and comes with a key (it can come with the backing plate if you're daring and unafraid : ). I'd rather trade for tooling than sell so if someone needs a good 4 jaw contact me and we'll see what we can put together. I'll send pics on request, there is a picture of it and the 5" three jaw in a thread on How much weight can a 1 1/2 - 8 spindle carry.
