Dual Loaded Table Tuba by a Teenager

[Titanium Hand]

Sheesh; those little JBL's look bloody nasty as all get out from the underside! Bummer reading about your mistake, you documented it exceptionally well though - for the greater good of BFM Kind.

I got held up on my build by Epoxy migrating into the thread of the hurricanes; requiring tapping, just when I was certain it was perfect. Everybody swears by tapping every hurricane, I thought I had been super careful and wouldn't need to... dun dun.

Prior to that, after meticulous cutting out of the baffle backer hole, sanding it for a perfect fit, I proceeded to use the wrong side of my circular saw on the sled and cut straight through the hole aargh! Understandably it too was around 11pm, so I was destined for disaster.

Hope the rest of your build goes smoothly BM

Don't give them the chance, when you get to that point fasten it the vehicle.

+1 To that, I used 4 M10 bolts through the base of my last box and the boot floor. Used a grinder to grind off the rest of the thread and welded the nut to the bolt. Had to drill it out after writing off the car in a smash. I definitely advise you to remove the fuel tank before you start drilling through the boot floor though and especially welding. As you're a teenager, its likely your car will be so low you won't need to weld the nuts. I had airbags so it was only low sometimes!

That hasn't happened to me yet, I've been extremely careful to not let any epoxy get into the threads.

As you're a teenager, its likely your car will be so low you won't need to weld the nuts.

Actually my car isn't lowered at all, it's a Subaru Forester, more geared towards off-road than Hellaflush kinda deal. I don't plan to lower it, I find those Honda Civic bumper scraper rice burners absolutely repulsive.

Here's where the TT will eventually make its home.



I took out all the carpet and storage compartments where the tire tools are to take this pic, so the 24" wide TT doesn't impede my rear view vision. I'm not going to weld the sub in there with bolts, mainly because the spare tire still needs to be available to me if I have a blowout or something. Plus, the sub is so heavy that the thieves would have to work pretty hard to get it out of there. In that time, I would already be at my car (I can hear its distress signal as well as a mother hears its baby's cries) and either calling the cops or doing something violent.

I plan to devise something where I can reuse this stock hatch cover. As of now, in its stock position, the TT will be taller than the bottom of the bar. If I can make some sort of cover that would look completely stock, that would be A+. Plus when the sub is on that cover will be flapping in the breeze, which is kinda cool.

Since I didn't have much time to work on it last night, I just cut some more wood. This afternoon I'll cut some more, and if I have time, attach the other driver.

Sorry for the slow, drawn-out build, but I'm a sophomore in high school and do a bunch of extracurricular activities, time can be scarce.
Plus I don't want to make another mistake so I take my time.

EDIT, no time for cutting today. Tomorrow and the day after tomorrow I should have a few hours to work on it.

Don't worry about the long build thread, it is your thread afterall. I am sure mine won't be a whole lot faster as I work 40 hours, have a 22 month old daughter, a wife, and DJ two nights a week. Time is definitely hard to come by, but being I should have use of a FULL woodshop, hoping to have fast progress (as far as cutting anyways).

can't wait to see more progress, and eventually the final product.

[bassmonster]

Of course, whenever you have a plan to get something done, school or work always edges in the build schedule somehow. Seems like the only time I'll have to work on it from now on is on weekends and school holidays. A snow day would be A plus, but for some reason it doesn't want to get cold in the south this winter.

Checked on the dried epoxy and hurricane nuts too. Wow. It seems there is nothing short of a car wreck that would wrench those hurricane nuts out of the wood. They're in there strong as a rock. Now the only thing I'm worried about is the seal of the driver gasket. I filled in the damaged wood with wood filler, I think it should give a good seal. Thoughts?

[bossman]

If you do all of the cutting on the weekend, you should be able to install 1 panel a day. They only take 15 minutes to install and clamp. I built mine a little at a time and I think its better to do it this way to give the rest of the panels time to dry.

[88h88]

The super PL stuff starts to dry in about 5 minutes and by half an hour is pretty bloody solid. Awesome but could be iffy unless you're on top form.

As for the seal just make sure you use the gasket tape well and you'll be all good. Double up if you need to as it'll get compressed down anyway.

Nothing done this weekend, too much schoolwork...

I hope to get some progress after school this week, but I can't predict my schoolwork load. We'll see.

Drop school and start building cabs, damnit!

[bassmonster]

So after school today I had about 20 minutes to work on it, so I drilled the holes for the other driver. Hurricane nut installation will probably proceed tomorrow after school. The build should go a bit quicker after this, no? (Assuming one panel and its braces per work session)

[Tom Smit]

Yup. Dry-fit, clamp, etc etc, ....make sure....make corrections if needed..... then PL. Slow and steady wins the race.

First off, yet another warning to be careful with the table saw. Went to cut a small piece of wood, thinking "Oh another easy cut". Went fine, then near the end a tooth randomly caught the edge of the wood, it hopped up and shot backwards at unfathomable speed. It only hit the stomach, luckily. I'm sure if a finger was there it would have been broken. Here's what it did to the wood.



Again, there are many many worse stories out there but it doesn't make it any less scary.

/end warning.

Got lots of progress done tonight (for me), I got a good couple hours in. First, I set the other set of hurricane nuts in. No problems at all, they went in quickly and nicely, and the driver was bolted up and the epoxy drying within 30 minutes.




Since I couldn't attach Panel 3 while the epoxy was setting and the driver bolted in, I set to making a box for my Bash 300. It was a quick set of cuts. I made my box 8 inches deep, for space for a fan mount, the depth is your preference, but a minimum of about 4 inches to comfortably fit. Here are the measurements for those interested. Top and bottom panels: 11" wide by 8" deep. Side panels: 6" tall by 8" deep. Back panel: 7" tall x 11" wide. Cut vents with a jigsaw or drill vent holes in any of the panels, most likely top and bottom.

I got all the panels for it cut, but I haven't screwed it all together yet. I will cut vents in the top and bottom panels; in the side of the amp I will drill a 3" diameter hole for the binding post unit, and tonight I also cut a 5 and 5/8" hole in the back panel for a "cooling fan". It's an "O2 Cool" desk fan, and it's LOUD, but I only plan to turn the fan on when I'm really running the amp hard. Why such a big fan you ask? 1) I couldn't wire up an old computer fan. 2) The fan will be blowing out a considerable amount of air out the back. It will end up incidentally sucking some heat out of the rest of my amp rack as well.

It will be wired to it's own circuit, the little board out of the desk fan's case (shown in the picture). I plan to hot glue this board on the back of the amp so I can switch the fan on and off as needed/wanted. I cut the hole for the fan and PL'd it in there. Soldering those little wires should be an interesting learning experience.

First off, yet another warning to be careful with the table saw.

Welcome to the club. Funny how things go fast things go from fine to bad when you have spinning blades in your proxy.

I don't think that "epoxy in place" method for the T nuts is such a hot plan. If you get epoxy on the bolt/nut they will tear the nuts out of the timber before letting go. I'm sure you're planning on taking the driver off before installing the panel, but you never know.

Thanks, thankfully it didn't happen. I made sure that there was no epoxy that migrated into the threads of the nuts, and they came out fine.
