securing inner port walls?

[Beatkeeper1 10+ year member]

A question on how to steady the inner port wall attached to the front face while the glue is drying. A bar clamp will not reach that far into the box. Should I drill pilot holes and use screws through base up into the port wall?

I always use screws anyway. I learned my lesson about "glue only" at around 3000watts and 30hz.

true should 1.5" screws be enough when using 3/4"?

you did a bad job glueing then. Screws offer virtually zero extra support when a box is properly glued

1.5 - 2 should be fine. I agree on using screws all around. glue alone can be fine...but it cost like...50 cents to put screws in too.

Yeah, plenty. You using coarse of fine thread? The coarse thread work better for me. Its a matter of opinion though.

I've done glue only on builds far exceeding 3kw with no issues.

coarse 5/8" after asking pioneer saturn. Should I let the glue completely dry before dropping those screws in?

Have to respectfully disagree. Test it for yourself. Glue two pieces together at a 90 degree joint and put a strain gauge on it until the joint breaks. Then do the same test with glue and 1.5" screws at 5" intervals and see which scores higher.

For those of you who glue only how do you allow pieces that you can't reach with a clamp to dry? Make them do a balancing act with no pressure on them until they dry?

Depends on your glue too. I've had more problems with titebond than I have polyurethane construction adhesive. the titebond is a lot easier to use though because it's not as thick.

Me too, but the one failure taught me a lesson........screws are easy to use and cheap.

use screws for that bish, you can even pull them out and seal the holes up afterwards if you want

good question.. i've always wondered this myself... which is partially why I started to do aero ports....

there really is no way to clamp it... for the port piece you pretty much have to just glue it and screw it..... that specific piece isnt AS important to clamp like the rest... clamps arent going to apply much more pressure than the screws anyways since people say you arent supposed to tighten the clamps to much

would a #6 drywall screw be appropriate?
