Topic tags/keywords: tip question lathe turning

I utilize the Teknatool SuperNova2 lathe chuck with a variety of jaws. The instructions for which and many of the YouTube instructional videos I’ve seen make note of the ‘dovetail’ configuration and how that grips the stock. My question is regarding when someone clamps square stock into the chuck where I don’t see a pre-cut dovetail profile.

Can anyone explain why you cut a dovetail tenon when gripping a bowl but it doesn’t seem to be required when gripping something like a square stock vessel? I’ve also seen this configuration without the support of the tailstock.

thanks…John

I’m not sure it’s “required” on a round tenon either, just a but more insurance and strength. I have not had any issues with clamping onto square stock, but if I have the extra wood available, I prefer to cut a round dovetailed tenon first.

Thanks for the feedback Marcus. I want to try my ‘first’ captive ring goblet and that seems like the right technique to utilize. Merry Christmas…

I guess I should add I always use the tailstock when I chuck square suck as well.

The Nova standard jaws are not a dovetail on compression but rather a bit of a ridge that bites into the wood. The manufacturer instructions say do not cut a groove. When you make your tenon, make sure you have a shoulder on it since that is where you get your gripping strength from.
