Dimensions: 16” tall x 16” deep x 62” long.
Wood: Walnut
Finish: 4 coats Oil/Varnish blend (per FWW article this month)

Yep, I dominoed and glued the bench panel cross grain to the legs. It’s an experiment to see if it fails. If it does, lesson learned. If not, I’ll have a better sense of cross grain limitations. There are 2 (3/4”x3/4” aluminum angles set in grooves and screwed to the underside to help support the span.

Looks great. Is there any bow in the middle when you sit on it ?

Fritz,

This piece is simply beautiful! This looks like it belongs in the De La Spada catalog! Is that top a two piece long grain glue up? Man this is nice. Do you have a shot of the underside showing the alum.? Seems like a great idea.

thanks all.

bfd: Here is a shot of the bottom. it’s probably bad form, but i typically don’t pay as much attention to the bottom as I do the visible surfaces…... so, i’m a little ashamed to show the “undercarriage” but I hope it helps. I routed an 1/8” groove (angle thickness) x 48” (angle length) deep enough to accept one leg of the angle. drilled and countersunk for #6×1/2” skrews and installed wih no adhesives. The top is 4 pieces, two wider in the center (with the sap wood) and two narrower on the outside.

jjohn: I weight about 200lbs and it flexes about 1/2” at the center. The addition of the angles made quite a difference. Before they were installed, it flexed about an inch and a half and the legs splayed out about 1/2”.

FRITZ! I love this piece!

Thanks for the technical info on the flex. It sagged more under load than I would have guessed.

Great Modern Design And Great Work!

Hi Fritz,

Thanks for the visual and further explanation. I think your solution of the alum L bracket is a good one and very clean the way you routed the wood so that it sits flush with the bottom. I really like the fact that you made the decision to use and highlight the sap wood. I think it adds to the natural beauty of the piece.

This is a great piece.

If this is a prototype and you decide to do a second version, I have a question.

Rather than screwing the 1/2” metal strips across the bottom, could you run two grooves 1/8” wide and 1/2” deep lengthwise in underside and then epoxy the metal strips vertically into the grooves? Vertically, the metal offers more strength against bowing. (stealing the idea from Wally Kunkle – Mr SawDust)

I am curious if you think that it would work. I have always used plywood for large surfaces and don’t know as much about how to compensate for wood movement. One possible hang up might be the wood movement in the walnut plank causing cracks/warping when restrained by the metal bar.

I too like the sap center on this piece and the finger joints look nice and tight…

I’ll keep my fingers crossed on the cross grain construction…I know you don’t want it to crack, but that still wouldn’t ruin the great aesthetic you have there!

I love the bench. I have an old slab of walnut my father acquired from an old workshop and has set arounf in his workshop for years. Its about that size but about 2 inches thick. I now know what to do with it. Great work!
