Subject : Sizing Air Form Bladders
Posted : 2006-05-08 1:21 PM

I'm making some sculpture stands out of 3/4" baltic birch plywood that I'd like to veneer in a vacuum bag using airform bladders if possible. The boxes all have 45 degree mitred side joints with 1/8" plywood splines, 45 degree mitred tops, and open bottoms. Three are simple rectangles: 11" x 11" x 30" tall, 12" x 12" x 36" tall, and 12" x 14" by 42" tall. The fourth is a truncated pyramid, 22" x 16" at the base, 15" x 9" at the top, and 33" tall.

On the www.vacupress.com web site, air bladders are sized with only 2 dimensions: 2' x 5', 2' x 9', 3' x 7', 3' x 10', and 4.5' x 10'. How would I determine the appropriate size(s) of air bladders for this and other types of applications?

Thanks.

Don,

I look at air form bladders capacity like this. If you take a 2x5 air form it has a circumference of 4'x 10'. Basically take the air forms dimensions and double them.

Now take the internal circumference of space you want to fill, in two directions, and this should give you which air form you need. Realize that a larger air form than you need wont hurt anything. What isn't needed just doesn't inflate.

Hope this helps.

Sincerely
Darryl Keil
