Good call chrisb, I'll work on getting the O.K. before proceeding.

Was just about to make the first cut.

That's prolly a misprint. I've never heard of 0.5", only 0.75" and up, from your local building supply stores.

I have the board at home now and the calipers read 19/32 consistently. Closer to 5/8 than 1/2".

This is a DIY for personal use with dimensions estimated from publicly available drawings provided by the designer - there is no limitation on whether or not you can do this. Cut away...

That's 15mm. Didn't know they made it.

Sounds good. If there is any problem I'm sure they will let me use them with my ACA in the Big House.

I don't think it is a misprint, I bet the nominal dimension is the thickness of the extrusion die. Once the wet foam is extruded it continues to expand before hardening at whatever thickness it happens to be based on local ambient conditions like temp, barometric pressure, humidity, etc. The only number they can quote is the extrusion die they use. As the 0.594 in thickness is neither here nor there - varies lot to lot probably... ???

Dunno,

I only deal with the thick stuff and it is dimensionally correct. (it has to be for design purposes) and I didn't think it came less than 3/4", that's all.

I think you'll find plywoods vary much more over their nominal dimensions than say, sanded MDF, or insulation panels

As I corrected in my earlier post, all I had to do was look at the Decware website to find that measured plans are available @ $20 - a reasonable figure

The design certainly looks less complex and practical than his corner horn design of over a decade ago. Those I acquired a set of, but never got around to building - as much due to the absence of a suitable room that could be dedicated to their use as their complexity. Well, OK, they're not the simplest design either, but the little DNA looks fairly straight forward.
