I made 3 ER25 chucks, one for the 1 1/2 8 TPI spindle, one with a hex shaft, one with a straight shaft for the rotab. Best to make it right on YOUR lathe, which will provide the greatest accuracy since you will be turning the taper while it's mounted on your spindle. If you buy the nut, you'll need to cut a 1.5mm thread. I did not have metric transposing gears on my 9A , so I substituted a 26 tooth stud gear for the 20 and set the QCGB to B4 which gives 1.50091 mm. I also made my own nut, without the eccentric, not as convenient but works ok. I chose ER25 because I had a full set from my mill and the full collet set was only $36 vs $130+ for ER40. Good idea to cut a male 1 1/2 x 8 TPI to test fit your chuck - wood works!
