Need just a few comments from loose tenon guys.

Making some decorative (not big, load-bearing) entry-way tables for Christmas.

Only have bits and tenons for 1/4” (and don’t particularly want to buy 3/8 stuff right now)

Working with 6/4 stock for the top (prior to planeing ) and 4/4 stock (prior to planeing) for the rest.

Will my 1/4” bit and the 1/4 inch tenons work OK for the build, considering both the 6/4 and the 4/4 will be planed down.

Here is my concern:

If I use a 3/8 mortise into 4/4 (which get’s real close after planeing to 3/4….....or 6/8) then that leaves only about 3/8’s of wood around the entire mortise. Kinda scares me.

Using Cherry.

Using MortisePal.

Not asking about the table top glue-up, just the joinery.

Thanks, folks.

Bruce.

Edit: Rereading this made me realize that I am really only asking about the 4/4 cherry, cuz no mortise/tenons will even touch the 6/4 top. Now I am not so concerned about the 1/4” bit and tenons.

But, I am certainly still asking…....(if and when I get the 3/8 stuff) .......would 3/8 m/t be too much for 4/4 ?

Sometimes my greatest fear is not being smart enough to even ask the right question.

Just finished helping with a quartersawn white oak kitchen, did the stile mortises for all the doors and
drawers with 1/4” mortise chisel. That left 1/4” on each side of the mortises to match the 1/4” tenon.
A 3/8” tenon would have left 3/16” on each side which is way unbalanced to my way of thinking. The
cabinetmaker I was working for would not even consider it, so I would say my opinion is to stay with
balanced joinery, of course I have occasionally had to admit to be in error, also can not understand
loose tenon, all of mine have to be snug fit.

Bruce my rule of thumb is to make the tenons and matching mortises about one third thie size of the finished material . I’m Pretty much repeeting what Gus said.

Hey my friend…....Don’t worry….be happy….....You’ll be fine making 1/4” tenons….These size tenons and mortises are pretty well the “standard” for this size of material…..If you plane down to 3/4” (S4S) from 4/4 stock, you have a 1/4” material left on each side of the tenon and mortise….Plenty of glue space for the shoulders of the tenon to fit into the mortise…..I have a Delta Mortiser to make the mortises, and I make my tenons one of two ways…...Either with a Delta Tenoning jig, or a set of dado blades on the table saw…...Nearly all my firniture is made with 1/4” m & t….........

Darn Right I remember.
