building a right side table saw extension support for an Excalibur dust collector hood.

Hello LJ members,

I purchased an Excalibur dust collector hood for my General Intn’l table contractors saw, and now need to change my right sided extension. The Excal is a very HEAVY item, and needs a real helfty support for it.
I am considering a torsion box system, but have not built one.
If anyone has built a support for this system, please send me a link or “how to” here, and I’ll build it.
Thanks to all !
