Practical?

i dont mind using screws to keep the panels clamped(i have no clamps)

For the lab12 horn il have to buy silicon sealant to ensure its sealed,rather than squirt 500ml of PVA woodglue down a join ,half of it missing as the bottle cant actualy fit in the tight folds :P

Cheers!
At moment im modeling up 32hz basshorn ,but having trouble making the rear sealed chamber as small as it should be -while keeping the horn length what it should! :-S

It only takes me 1hr to CAD a horn,but its trial and error to get a horn that has no wastage :-S
