Whelp, I Hate Particle Board (Major Cab Surgery Content)

Normally I have nothing against CBS era fender, but particle baffle boards? Really?

EDIT: I didn't even notice this until I posted, but look at that bottom bolt - that's terrible.

In addition to this wonderful development, some of the other bolts holding the speaker to the baffle board were coming loose. I would have loved for there to be a quick and easy fix to this problem, but my reality was replacing the baffle board.

Getting it out was pretty easy. Taking off the trim (it's a drip edge Bassman cab) and grillcloth took a while, but it was removed with no damage to the trim and next to no damage to the cloth.

I went out and got a piece of plywood large enough for the job. I measured the thickness where the speaker mounts to the baffle before I took it off. Wish I had known better - once the grillcloth was off, I found wood trim around the baffle. My guess is that it was put there so the cloth would be flush against the piece where the logo goes in the top left corner.

Here's a picture of the old baffle:

As the second picture shows, there was more damage than I knew - on the grill side, it appears that the particle board was corroding away. I'm really glad we decided to make a new board, as the cab needed it more than I thought.

You can see where the strips were removed - we reused those for the new baffle. The port confused me and my father to hell, so much so that I made a whole new thread on it. For the life of us we couldn't figure out why it was there. My best guess was that it was a prototype idea of some sort and made it onto the template, but they didn't like it nor could they change the template without stopping production and losing money, so they covered it up. This cab has always been the best cabinet I've ever used, so I put the port in and will most likely put the port covers back on.

Anyway, here's a picture of the mostly finished baffle:

The speaker holes aren't perfectly circular, but they're pretty good for a DIY job I think.

Fits perfectly! Well, once the grillcloth and trim are on, it will.

At this point, all that's left to do is drill the holes for speaker bolts, paint, cover up the port should I choose to do so, re-attach the grill and trim, and screw it back into the cab. All in all, I'm much happier with the result than I thought I would be. Shoutout to my pops, who did all of the woodwork while I was at work so I could have my cab ready for the next band practice. He's ****in' awesome.

It's funny - I only found out about this because one of my speakers crapped out on me. I bet if it hadn't, the baffle board would have eventually just collapsed under the weight of the speakers.

Anyway, I've already got a Cannabis Rex that sounds great in this cab, and I've got a Texas Heat that should be here sometime this week that should sound excellent on my new plywood baffle.

Good work man! the plywood might even give the cab a little bit more punch and clarity.

Re: Whelp, I Hate Particle Board (MAJOR Cab Surgery Content)

Thank you sir. That's actually what I'm hoping for.

Re: Whelp, I Hate Particle Board (MAJOR Cab Surgery Content)

I would have likely gone the lazy route, rotated the speaker 45 degrees, and remounted the bolts in previously undrilled areas of the particle board.

The solid ply looks way nicer and, as stated above, might actually add a bit of punch and clarity due to the more solid construction.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

if you want something done right...

(great job)
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

They actually were already drilled - I'm guessing that the original speakers (long gone when I got the cab) were 8 bolts, but some numbnuts decided to cut half of them off. Plus, even if I had just rotated it to be in between the holes, there was too much cracking and warping to make it worth while. And, in order to put bolts in the baffle, I would have had to take off the grill anyway, which is such a PITA I just figured I'd make a new one that will last for years and years.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

I would never argue the merits of MDF, Press-Board, or whatever. But keep in mind the cab is 40-45 years old. They simply did not look THAT far ahead.
Anyway.....
...yeah, great choice to do it right with ply. It will last another 60 years, or until the rest of the cab falls apart.;)
I have a real liking of Eminence speakers. The Texas Heat is one of my favorites. Do not think I have ever read a guy say he did not like the C-Rex.
Are you going to run them together.?
I have always had a soft spot for mixing speakers as well...:)
best
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Yep, I'm going to be running them together. I'm hoping that the three db sensitivity difference won't be an issue. It shouldn't be, as I was running a V30 and the C Rex without a bit problem.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

I run a swamp thang and a tone spotter together in a 2x12. Eminence makes some fine speakers. Good work btw!
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Just drilled the pilot holes for the speaker bolts and sprayed the grill side of the baffle black, so you don't see the color of plywood under the cloth. Once it dries, I'm going to drill the bolts for the speakers. I'm going to use a hot glue gun to attach the cloth instead of nails. Seems like a better idea to me considering the age and condition of the cloth.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Good save bro! You need to staple the cloth though.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

You could glue it, and maybe being sandwiched in there it will hold, but I'd be afraid of it pulling out when someone is moving it and puts their knee into the cloth a bit too much, etc.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Very cool!

Good work.

At least your cab is old enough to have a floating baffle...the later ones were still particle board but they were glued in so you couldn't even swap 'em out!

Hope it works for you my man.
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Looks good nice job...I've used 3M Super Spray Adhesive on tolex etc.in the past with great results..I agree about pulling the grille cloth tight and stapling(with an air stapler better)..

That's a good point - however, my cab is one of the drip edge silverface cabs, and the silver trim will get nailed over the cloth around the edges, which should be fine.

Yeah, good solid ply was clearly the necessary change then. It definitely looks like good work!
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

Always curious about this...
What size did you guys cut the holes to.?
What did you cut them with, jig saw.?
Thanks
Chip
 
Re: Whelp, I Hate Particle Board (Major Cab Surgery Content)

I've no idea what size the holes were cut to, as my dad and brother handled the woodworking while I was at work. I know they used a jig saw, though.
