## Questions & Answers

**Q: does this fit your 3" chucks? and if so what model numbers are the chucks.**
A: YES, SEE OUR HHIP# 3900-0031

**Q: I bought this item and the boss where the chuck mounts is the wrong size. i bought steelex m1057 3 jaw chuck, 4-inch. the back of the chuck is 72.05?**
A: We show the boss to be 77.5 mm on the adapter. If your chuck is smaller then you will need to turn the adapter plate to fit. Please advise

**Q: can i get this chuck with a 1/38 inch by 10 backing plate**
A: Sorry, we do not offer that size. We do offer a blank you can machine See our # 3900-3305

**Q: I purchased hhip 3900-4131 (3", 4 jaw). my sanou k12-80g (3" 4 jaw, self-centering) requires a 3 hole backplate. will hhip 3900-3110 fit my chuck?**
A: I looked up the drawing of your chuck, and it shows a 66mm (2.598") bolt circle.  The 3900-3110 drawing shows a 2.60 bolt circle.  Since they're within 0.002" they ought to be compatible.
