Anyone here who has made a post and rung chair, (or anyone with some knowledge of strength of joints) I have a quick question about tenon cutters. I'm consider a powered tenon cutter for rounding the ends of the rungs. LV sells 2 I think will fill the bill. One is The mini tenon cutter

Which makes a 9/16" tenon, the other is the Power tenon cutter

Which makes a 5/8" tenon.
my question is this. Do you think a 9/16" tenon will be strong enough? Each chair or stool will have 8 rungs, 1 for the middle of the leg, the other for the seat, on all 4 sides. I think if I use nice, rived, straight grain wood, 9/16" should be sufficient. I am willing (reluctantly, as cash is tight, and this is being funded by a generous friend in exchange for computer help) to use a 5/8" tenon if it will be significantly stronger.
any ideas? Am I worried about nothing? It is only 1/16" difference after all.
thanks in advance, as always.
