John,
I’ve seen a number of pictures of torsion boxes under construction. They all seem to use a zillion little square pieces. I thought, well, I’ll build one, but use slotted boards that run the length and width of the box and just slot or interlock together.
Then I thought, maybe there’s a reason for using all the little pieces rather than the interlock method.
Is the zillion pieces method inherently better for some reason? Strength? Flexibility?

Pieces
Jonnie, when I build one. I used long strips for the length wise run and small pieces for the cross pieces. Important thing is that the gaps are minimal. I did not run my cross pieces directly in line, I staggered them, so I could glue and nail them easy. I wil be curious to hear from John as well.

Staggered Pieces
Azmo,
That's a good point about the staggered pieces. I hadn't thought of that one.

Azmo Method
I've always used Azmo's method.
It seems to me that a slotted frame would be much slower.
I anticipate building one sometime in the near future to use as a combination outfeet, assembly and etc. table. I would think that the slotted method would be the faster. Has anyone tried both so they can tell us?
Torsion
Tinkerer,
I'm thinking I'll build a bench/cabinet top using a torsion design. The top is for a beater bench, for which I'm in the middle of building cabinets.
I want to make the the honeycomb only about 3/4" thick, then cover it on both sides with skins at least that thick.
Given that objective I guess it isn't so critical whether I offset the crosspieces or not.
I'm sure it won't be the only one I build in my life and it would be nice to know.

I'm confused as to what you mean by "beater bench" unless it is something you pound on. If this is true, then you would get a lot more local rigidity by two solid sheets glued together rather than spacing them with the honeycomb core. Also the 3/4 " core would add very little over all rigidity.
Considering that the overall rigidity of the piece varys with the square of the thickness of the core, a three inch core would give sixteen times the rigidity of the 3/4" core.
Since I don't plan on hammering on mine, I'll probably make it with a 3/4" top, a 3" core and a half inch bottom
Beater Bench
Tinkerer,
The beater bench is shown here. The drawers are built since this picture.
Nothing against you, certainly, Tinkerer, but I'm done. This community stuff doesn't work for me. I tried real hard.
You're very good people. The best. Patient and kind. I wish you all the very best.

Thanks amigo
Jonnie, sorry to see you go. Enjoyed you around here, you need to know that. Best of luck to you as well. You are welcome to beat on my bench anytime!

Azmo and Tinkerer,
Sorry, I didn't get these messages until now. Thanks guys. I appreciate your kindness.
And too, I didn't mean to give the impression that Knots itself has anything to do with this decision. It's all on my side, my own issues.

As with the rest of the gang, I hate to see you go. I've slowed down a lot and with all the others gone, it doesn't generate much exitement. Have a good life and I hope to see you in the next life.
Tink
