Stupid Question of the Day

[Joe McMahon]

Being a newbie, I came on to a Teknatool nova dovetail chisel. I do have a nova jaw set. I understand that the chisel will make a tenon that will perfectly fit into the Nova jaws.

Now for the dumb question: How does it work? Is the tenon tapered? If so, then the chisel would have to be used from the end of the turned cylinder with the edge of the cylinder facing you?

Sorry for the dumb question but I just can't wrap my pea brain around this one.

Most of the Nova jaws do take a tapered tenon. There are a few that are straight. I use a diamond point scraper to make mine and yes I make the tenon on the tailstock end. You can use the dovetail tool but it is not required. A skew will work as well.

This tool is for recess dovetail. Not for external tenon.

Thanks for the quick replies

I use a Dovetail gouge just because I have one. Mine is ground on a 90 beacuse my Baracuda jaws are 90, not tapered. A skew will work fine...layed flat of course!

"Make the spigot as parallel as possible to maximise the efficiency of the clamping action."

From the Nova SN2 manual. The dovetail is for expansion only.

Yup, to what some here have said, the dovetail is for expansion. Do a 90 on the tenon. Here's a case where you can probably put that money on another tool and create your cuts like you need them with existing tools.
