New Build of Old-style T39s

[miked]

As far as Informative Answers go: That was the most informative of an informative answer that has ever informed the not formerly mentioned, but yet until now, uninformed poser of the informative question.

I like the idea of jacks on the back, as well as having them slightly hidden and hard to get to for the uninformed yahoo trying to poke at your gear. Yet I do not like the idea of having to drill 2-4 holes in the horn panels to get the wire from jack to driver. I am strongly considering putting the jacks on the access cover, for reasons that I'm sure you're aware of, so I won't detail them. Problem is that it looks like crap. But a 12-inch run of wire, with no need to glue it down or drill holes, is oh-so-appealing.

Please do post pics of the access panel before/after. Thanks much and again, congrats on your two new babies!

You only have to drill through one panel. Putting them on the access panel does limit your setup possibilities. Even when you just want to RTA 'em out in the yard, it's a lot easier to set your tops on the sub....can't do that with wires sticking up.

I'll post pics of the access cover later today. Ran into roadblocks yesterday and couldn't get back out to the garage.

By request.....

I made the one-piece flange instead of using strips. I really liked this better. It kept the flange perfectly flat, which it tough when trying to marry up four strips.

I put a band of weatherstripping around the outside, then put one to the inside with cutouts for the screws. Also predrilled the pilot holes for the screws.



Next up was installing the drivers.....Last time I did this standing up over the top of the box....Must have grown a brain cell or two since then - laid 'em down on their fronts...much easier while battling those hurricane nuts.



The gasket on the 3012lf is thick and pretty stiff, but it will compress all the way down with the bolts and hurricane nuts. Not sure if you can get it down this far down with screws without 'em tearing out.



Then it's time to slap on the lid.....it stood a little proud - probably due to having two widths of weatherstripping.

After 24 days of gestation, I'm proud to announce the arrival of twin Titans. 30 inches tall and 25 inches wide. They weighed in around 90 pounds each. Upon being fed 60hz intravenously, they both began to hum.....

The sunlight makes 'em look dusty and washed out, but their color is fine and neither show signs of expelling air other than through the approved outlet..



As with most children, their activities will be limited (and strongly enforced) - as too much power can corrupt. As per their culture, they will be housed packed tightly in a dark trailer....only to be released occasionally to kick butt on unsuspecting gear snobs.

Very nice Bruce,

When looking at the picture of the driver through the access cover it looks like you had to nibble a little bit of the flange to get it in there. Is it really that tight a fit to in there? Must be hard getting a non neo driver in there. Or maybe its just the picture.

Good eyes

I made the flange wider all the way around, so yes - I had to nibble about 1/8" for 'em to fit. I don't know that the non-neos are any taller (not counting the Lab - it wasn't one of the original drivers and it won't fit).

Bruce,
Congratulations on the arrival of your newest twins!

Great work!

Having built the newer version, that flat expanse sans access cover above the mouth looks, well, virginal

Looking forward to seeing what you think of 4 cabs instead of two.
I felt the jump from 1 cab to 2 didn't make the impression on me that going from 2 cabs to 4 did...

As a warning with any aging offspring they will indeed cause all sorts of trouble when they get near there siblings leaving you to pick up the pieces once the cops show up. You will only notice this behavior when all 4 of them are allowed to run together. To keep you out of any future trouble I suggest that you keep a tight reign on them when they are running as a pack. As you already know they tend to multiply when together for any amount of time so you should keep a close eye on that as well.

Due to your well documented build and professional final product. You Sir are the first recipient of the USA version of the Australian Harley award.
I present to you the first annual Biggerrigger Hat Award.
Ladies and Gentleman lets get a warm round of applause for our builder Bruce Weldy for his ongoing support to the BFM community and his great well documented builds and professional final products.
Drum roll please........ !!!!! That's right folks not only is it the first award ever given but its a perfect 5 hat award.
This folks is how its done. Great job Bruce enjoy your hats!

[miked]

Very, very nice! They look fantastic...and a 5-hat award to go with it? Sa-weeeet! I can really appreciate how tight your builds are; I hope to be that good one day.

Thanks for the pics of the access cover. I wanted to use t-nuts/bolts for mine, but there's no way to recess the bolt heads with only 1/2" of material to work with...bolts would go right through the wood. What type of screws did you use? Are they the 1-inch, coarse thread screws? BTW: Do your cabs have feet?

I laughed at this:

Four, 25" T39s loaded with 3012LFs will certainly remove any doubt about "DIY gear" from anyone's mind. Will you v-plate the stack of four, or are you making another v-plate and then plating 2 pairs? Just thought I'd ask. Again, congrats; they are a fine looking pair of Titans!

Thanks Grant. I'm looking forward to it too. Unfortunately, I don't think I'm going to get to really witness the maiden voyage. I probably won't get to run sound on 'em until my band plays in June.....and I'll be on stage. But, I'll have 'em out at least 3 more times during the summer - so I'll get to check 'em out then.

Thank you.....and I'd like to thank the Academy and all the little people that made this award possible.

Hey! I like the hats....being an old Texas Redneck and all....

[Bruce Weldy]

I appreciate that - they aren't as perfect as I'd like 'em, but I try to balance my "anal" side against my "get the damn thing done" side.

Thanks for the pics of the access cover. I wanted to use t-nuts/bolts for mine, but there's no way to recess the bolt heads with only 1/2" of material to work with...bolts would go right through the wood. What type of screws did you use? Are they the 1-inch, coarse thread screws?

My first ones have T-nuts and a phillips head screws that are countersunk. That's how Leland's kits used to come. Now, he's using a #10 screw that's 1.25" long (I think...may be #8 and 1"....didn't measure 'em, just used 'em).

Believe me the screws are much easier. I used 12 on each cover. Probably wouldn't hurt to use a couple more, but with a double layer of weatherstripping, I don't think they are going to leak. And hey, if Leland says they are ok, who am I to argue? He's built a hell of a lot more of these than I have.

BTW: Do your cabs have feet?

Yep - all my cabs have feet. That way, they can walk themselves into the trailer. At least that's how I'm trying to train 'em....ain't working to good yet.

Will you v-plate the stack of four, or are you making another v-plate and then plating 2 pairs? Just thought I'd ask.

I hope some day to v-plate the whole stack - just because... But, for the Concerts in the Park series this year, I'll be v-plating two on each side of the stage. It's a wide stage and most of the crowd sits to the left and right. I can get 'em split about 40 feet, and with a high pass of 50, I don't think I'll have too much of an issue.

And speaking of V-plates......

[Bruce Weldy]

Had some time, so I started the other v-plate today.

I've had a 4x8 sheet of 1/4" Luann plywood hanging around the garage getting in the way for over a year now....don't even remember why I bought it.

So, I sandwiched a piece of that on each side of a leftover piece of BB (had to scarf in a piece on one corner because it wasn't quite big enough.

Kinda' looks like a single piece of ply, don't it?


Got it cut to size as per the plans and rounded over all the edges.



Looking good, right? Decided to get out the old one to use as a template for handholds, alignment stops, hole for clamps, etc..... oops....



I forgot that if you use the chevron corners, the plate won't sit down properly unless you lop off the corners some. Anyway, that will be done tomorrow.

I also finished my v-plate clamps that I designed the last time. I'll post some pics of those tomorrow.

Here's the build thread from the first time I built 'em. Only difference is that I didn't weld the bolt to the plate this time....just put on a nut.

[Bruce Weldy]

Ok, got cracking this morning and knocked off the offending corners. Then is was time to cut the handhold - this thing is rather unwieldy to carry without one.

Once again, the mighty jig saves tons of time. I didn't have a router the first time I built Titans. The time saved on the handholds alone by using a router and a jig has got to be at least a couple of hours when you figure in having to cut two holes, saw two (hopefully) straight lines, then rounding them over with sandpaper - with my extra handhold on the front brace - that's 5 handhold for each one....plus one for the v-plate.

So, making a jig is well worth the time.



Then I put on the stop blocks. These make it easy to align the plate. Just shove it until it stops - no having to line up holes......next was putting on the hardaware (clamps).





And now for a test fit...



It all fit fine. Headed back out to sand, paint, duratex, and apply the weatherstripping. Think of this as diapering the twins...

I made the one-piece flange instead of using strips.
