Can some one help identify the tapers on this spindle adapter[?]. I am most interested in the short taper on the right. This is for chuck on a Chinese drill press. The small end measures .760 and the larger .810 this is with a harbor freight caliper. I want to replace chuck with one that has a jt33 taper. Want make sure of what I got. The other end i assume is a morse taper not sure which one. Thanks
