Months ago when MKSJ alerted me of such a deal on the Bison combination chuck, I managed to snag one, but it sat for months still in its shipping wood box. Last week reading and following Paco's thread on his ACRA lathe, he posted that he transferred his Bison Combo to the D1-6 backplate for the ACRA. Since he freed the D1-4 backplate he used with 1440 lathe, I asked if he were willing to part with it. My SBL 13 has a D1-4 spindle, I thought the combination chuck would be a perfect fit for it. Paco offered up his backplate for a very reasonable price, so we struck a deal.
It took 2 business days for the priority box to get to Austin from Tucson. Mounted and tested the backplate for runout, near perfect, bolted the chuck to it, runout just the same. Set up the jaws and dialed a 1 inch precision rod from Pacific Tool and Gauge to near zero.
Finished turning down an AR15 barrel from a 1.25 blank, no follow or steady rest, using the combo chuck.
The combination chuck is right at home in the SBL 13.
