Can this stuff be used if there are slight gaps between where the 2 pieces of mdf join? I just glued the back bottom and sides together and im letting them cure. Once its hardened up im gonna use some brad nails to hold them securely and then I'll drill the pilot holes and use proper wood screws.

For the gaps, can i use this fibreglas filler? Is that ok?

Yeah if its just for flushing up a visual imperfection, dont use it for anything strength bearing.

why would you add screws AFTER the glue has dried?????

I normally mix sawdust and glue if I have to fill a gap or chipped corner...

yes you can its fine, and if you have some to spare it will work great.

Im doing the screws after the glue becuase i dont have anything to hold the 2 pieces together so i can line them up and drill the pilot holes.

The screws are to hold the pieces together while the glue dries if you don't have clamps. Is that what you're doing?

i was thiknign to use screws so the box is stronger and more re-inforced rather than just gluing it together.

you have some learning to do my friend.

just line the pieces up and drill a pilot hole

then glue

then screw.

and i think a bead of liquid nails would work better than that stuff.

shouldn't need liquid nail or fiberglass to fill if you can cut a straight line ...

so i shouldnt use screws now? This is the first box ive ever made. I used wood glue and i used LOTS of it. the only pieces remaining now are the front, which i still need to make the cutouts for and the top. ill take pix and post.

screws add NO strength, that's what the glue is for. Lay a thick bead and it should come out both side of the joint when clamped/screwed together.

Liquid nails ***** *** do NOT use it. If you have a cut that's a little off mix some sawdust and glue and put it on instead of straight glue and it'll fill the gap.

lol. use plenty of wood glue and use only a couple of screws to hold the mdf together, dont make it out to be all complicated.

the enclosure I have in my sig, has a wood frame with a couple screws holding it together, glued, and fiberglassed. solid.

I don't think so, bondoglass is strong. PL premium would work good for gap filling as well.

Heres some pix of the box so far. I test fitted the sub and theres a bit of play, i think i may have cut the hole slightly larger than it should be. Im not sure if it will work or if its gonna let air out.
