Question Advice wanted on glue down

So I woke up yesterday and decided I'd try making my first speaker cabinets (for a pair of Flex-12s), so I went down to home depot and told em to cut a 4x8 sheet of MDF so I could take it home as a single person. Luckily I told them to cut an inch over what I had in mind because their saw doesn't cut straight.

I was confident a circular saw, sheetrock square and other tools would do, later to find out I had to get out a square to straighten out my circular saws cuts (my table saw can't cut at 0 degrees, no sled either), bar clamps to hold down the sheetrock square on both sides (as a guide), not to invite a friend over to chat while making cuts [on the wrong side of the line], and to use material thats laying around as a weight or raised cutting surface.. after returning a 2x4 sheet for another 4x8 I had all the faces cut for the cabinets.

Take a guess how well the fit went. I'm not sure how much gap is too much so I'd like some advice going forward from this point. I've got PL Premium for the adhesive.

For tools I've got:
Circular Saw, Chop Saw, Jig Saw (all with fine blades)
(4 of each) 12" & 24" bar clamps, (2) 90 degree clamps
Finishing&Brad Nailers
Caulk gun, Caulk joint wiper (tired of throwing away rolls of paper towels)
Sanding blocks, sanding paper of various grit
measuring tapes, squares, marking utensils

Edit.. I've got drills, their bits and spades too but I forgot to mention I haven't yet ordered the speaker kit (which includes baffle) so I haven't made any cutouts for the front yet either. I figured I'd have the 5 faces done, do some bracing, then finish with the double baffle but I'm not confident that my cuts will allow me to do that.

Looks fine to me. I'd bet a clamp will close up that gap in the bottom/back of your picture. If not PL Premium should fill it.

Keep it up. You're doing well.

Oh...measure twice, cut once.


On second thought, one piece of advice I may offer...I'd wait to glue up until you have all the baffles. That way you can assemble off of them to make sure everything fits together.

I figured I can't glue front/back to top/bottom because of the spacing (everything goes around the top/bottom) so if I were to..
glue Back to Right (90 degree clamps)
then Top and Bottom onto those (bar clamps) and wait for it to cure
make braces with the Left face resting on top
possibly glue the braces in place, to secured faces
adjust if need be and glue down Left, Front to the sides and braces?

I see PL premium is unforgiving for removal so I don't want to make costly mistakes.

A 4x8 sheet weighs about as much as a dead 12 year old. What kind of weak sloppy serial-killer are you?

So dry placing more pieces today in anticipation of tomorrows delivery, what advice could you give me on evening these sides out? I think that gap, ~1/8, is too big.

When glued up to that point, 5 of 6 faces (front missing), should I just run each side through a table saw to even out the front face? clamp down the t-square and try to match each side with the circular saw?

I'd probably do the lowest point on the box, that side I showed was the worst side, through the table saw since the back face can't be crooked.

I think I got the size of the bead right when I applied the bar clamps. After letting it sit an hour I was able to scrape the excess PL Premium off as it was in a paste-like consistency and came off the tool cleanly.

Decided not to throw the box through the table saw and just shim it, the second box came out better.. I clamped them and trimmed excesses off with a jigsaw versus a circular saw that time.

But my main concern is bracing, I've got the side-to-sides in there held in place by friction and was wondering.. do I glue around them? smear PL Premium around? etc, and if I should glue down the baffle now before doing the front-to-backs?
