just found this group and have a question...

I'm building a jewelers bench for my wife. And I'm cutting dadoes for 1/4 walnut ply panels. And was wondering how deep should the dadoes be?

Use brad nails, then paint the walnut so the paint drips into the dado
and holds it firmly in place.

I've used magenta and SBB (what we used to call Shit Brindle Brown)
successfully as well.

I concur, FWIW.

Toe-nailed, of course, but if it will be load bearing then use screws too<g>

I'd probably go with about 1/2" myself. You'll get plenty of support, but
not be so deep you compromise the piece you're dadoing.

Seems then that the solution would be to go with 3/8" dadoes and just
make sure that you're not compromising the tenons. If you can't go 3/8"
without hitting the tenon, move the tenon.

Sound advice. Just a couple other points. For proper adhesion, the paint must
be bright yellow in color. Use some 80 grit sandpaper and sand while the paint
is still wet to fill the brad nail holes. Any leftover paint can be used as a
fine finish on your rifle or shotgun stocks.

These will be semi structural, like ply into sides of a desk(which is essentially what this project is).

I'm not sure the thickeness of the rails but the legs are like 1 5/8 thick . The rails are bigger than 3/4 for sure though. I'm afraid of cutting into my tenon on my rails.

1/2" deep is a good safe depth.

It all depends on the walnut and its use. If you are using 1/4" walnut to
divide pigeon holes, a quarter inch is plenty. If its structural, you will
need 3/8", assuming your cutting them in 3/4" inch stock.

From your descriptions thus far:

A 1/4" dadoe is quite sufficient for a plywood panel that is framed by
rails and stiles/legs.

That depends. Generally 1/2 the thickness is acceptable. but in
situations like dividers for drawers 1/3 of the thickness is preferable.

For side and back panels? Are space balls being used?

A general rule I have been told and do is dado 1/3 the thickness of the
piece of wood you're dadoing.

Yes, but only lightly scuffing. I'm sure you meant to say that...

Let's see now...

One said: 1/3 of the thickness the dado is in.
One said: 1/4" or 1/2 of the thickness the dado is in.
One said: 1/2".
One asked something personal about your balls.

For me, I'd go with the 1/4" depth unless the dado is going in 1/4"
material. If so, 1/8" is adequate.

I wonder what the next four or five answers will bring.
