Planning to turn bowls for the first time but confused over the choices for chucks.
Any guidance on what I should purchase? 12” diameter and smaller bowls turned on a Jet 1236 lathe with a Morse #2 taper.
I'm Nova. Since I gleefully retired my first "Masterchuck" from all jaw duties. Scroll chucks of all brands are somewhat equal, so quality of hold can't be determined by cost. Get the one that has a good selection of options for holding your work. I like the pin jaws (1"), the standard 2" and the so-called 75mm (which ain't) "bowl" jaws. All of which have internal wedged mortise holding capability. An internal hold made possible by the single holdover from that Masterchuck - the pin chuck.
Not only does it start almost every rough operation MUCH more safely than a spur center, it's much less fidgety than a thread and requires less prep than a faceplate. Mine now from
https://bestwoodtools.stores.yahoo.net/ , because my original from the Masterchuck was 1"8 only. When used as I do, between centers until relative circularity is achieved, it can then allow me to make the mortise I will reverse to the scroll chuck, saving depth in the most typical bowl configuration. Possible with the others, but much more risky.
I reverse and hollow, leaving a pillar with my pin chuck mount for remounting after a wet piece cures. After cure, a 1" bit reams the original hole, and the piece is remounted and turned. It's possible, but not as convenient, or to this coward, safe, to do the same with the pin jaws. I do on shallow pieces all the time, but with the Nova 3000's capacity at 15 3/4 over the ways, I prefer the pin chuck for pieces over 2-3 inches deep.
Not sure of current pricing, but for 90% of my current work, I would purchase the pin chuck over the "bowl" jaws. I use them for lidded boxes and such, not bowls.
Don't forget a live center for the tailstock. Get one that has a cup center option as well as a threaded self-made add-on capability. Mine's also a Nova.
Better to follow the leader than the pack. Less to step in.
