I have to tuen a bottom for a salad bowl I’m making so i have to round a maple blank and cut into it a recess to hold my my nova chuck jaws since i cant use wood screws i was considering double sided tape which seems easy to use and the glue and paper trick which i am not familiar with, since i have to cut a 1/4 inch depth into maple im concerned that the whole thing will fly off and hit my wife car. Any suggestions would be appreciated.

I tried using the flat expanadble jaws for the nova chuck but the bottom is 11 1/2 inches wide and it does not open enough

I agree with John. Talk to the wife about parking her car in your woodshop.

I would not trust double sided tape for this purpose.
The glue method involves making a mounting plate, usually 3/4” plywood, screwed to a face plate. Then you apply wood glue to both the plywood surface and the bowl blank. With a piece of newspaper or brown paper bag between the two parts clamp them together, making sure they are as close to centered on the face plate center as possible. Wait 24 hours and do your turning. When finished take a broad chisel (1” or wider) and cleave them apart at the glue joint. The paper will give way before the wood and all you have to do is scrape and sand the glue and paper off the bowl.

Because this is a bowl you can always screw the face plate directly into the blank on the side that will eventually be the inside of the bowl. The holes will be removed when you turn that side. Completely turn the bottom (including sanding) and add either a mortise or a tenon for mounting the bowl on your chuck to finish the inside.

If you have a router you can try a method I use for mounting rough blanks on my chuck. I have a blog you can check out here: https://www.lumberjocks.com/LesB/blog

Did your chuck come with a “woodworm” screw?

Cheers,

I would not use plywood for a glue block. If it delaminates, which it can easily do, you could wind up with your bowl slamming into your faceshield. Use a solid wood block (preferably hard wood).

Here is a good video from Lyle Jamieson on glue block prep. He has another for bottom prep. Thick CA glue is my preference, particularly since I’m usually turning wet wood. I typically put a tenon on the glue block and use a chuck. I only use glue blocks if the wood is not thick enough for a tenon. Rarely use a mortice.
