I need to make an arch with a cross section of 3″×3″ for an outdoor table legs using bent lamination
I plan to experiment with 3/16 to 1/4 laminates.
The arch will have about 26" radius since the table will be about 30" high.
for 1/4 " thick laminates I would need 12 of them. Each laminate would be about 90" long.
That’s pi*radius for half a circle: 3.14*26 = 82.
Since I am going to have a stair effect on the ends during lamination I will add another 8" for the ends waste.
All these number are rough number but pretty close to final.
I need to know the best way to make the form so as to minimize the wood needed for the form itself and yet making sure it does not collapse during clamping.
I thought about using plywood or MDF, cut the arches on the bandsaw, stack them about 3.5" high and glue them. That is a lot of waste and probably heavy.
The other way would be out of 2×6 lumber like below. Staking them until I get the right height(3"+)
I need ideas/suggestion please.
