More DIY - Cab this time

[JohnH]

ha ha ha, yeah that's happened to me so many times when I'm drilling pedal enclosures. It's so frustrating

Nice project.
I have a Vox 1x12 with a vintage 30 in it - nice compact cab

I also have two unused vintage 30’s in boxes ready to become a 2x12, so watching with interest

Managed to get stuck in at the weekend, with my limited tools and woodworking skills.

A start, the 4 main pieces and batons cut to size. And yes I do have serious workshop envy looking at the post of a lot of your sheds. My workbench, the top of the chest freezer in the garage :-)



I don't have the tools to do finger joints so basic butt joints with glued and screwed batons for support



I used a router for the first time to round over the edges, wanted to get a 20mm bit so as I could do a full radius cut on the 19mm pine, but the Big Green Shed didn't have any, and I was too impatient to wait and order one, so a 10mm would have to do. The routing wasn't great, but nothing a bit of sanding and tidying up could fix.





To be continued

Being continued....

a first sand and the corners cleaned up.



Took 2 attempts to get the baffle cut, first time tried the dremel with the circle cutter, was a disaster. Second time with the jig saw a bit better, again a bit of a sand will tidy it up.



And after all my judicious measuring and using a guide block I cut, seems its still a bit out on the fit of the back panels, will need to sort that out. planning on cutting a 3rd section that can go in or out so I can try both open and closed back.



A bit more timbermating and sanding to do, and in the meantime will order some Tolex and other bits an pieces to finish it off. Probably a while till I can get hold of a speaker, unless something pops up on ebay cheap.

Are you planning to front or rear mount the speaker? If rear, then remember that those rear panels need to be removable if you ever want to swap the speaker, or get to it for some bolt tightening. So screw them. but don;t glue them. If front mounting, then whatever grille you fit needs to be removable as well.

A friend is making me a small bass cab for a 10" speaker I provided for the build (300W Celestion with a neo magnet) as I gave him some speakers and bits. He's bringing it over tomorrow. for some testing and tuning.



That speaker is front mounted using 5mm barrel headed hex bolts and T-nuts for a fixed nut installation. As it's a sealed tuned port design, it had to be front mounted. I'll be making a metal grille for the front

It may depend on the speaker as to what bolt size fits best, but Celestion seem to use 5mm in all their suggested cab construction details, and although 6mm can be made to fit with a very small amount of filing, 6mm T-nuts then get very close to the edge of the circular cut-out.

The bass amp I have is a small TC BH250 Mk 1. The speaker is a 4 ohm one so I can get the full 250W from the amp if I ever want to. It's only really designed for home use and it won't have a huge amount of bass end, and above around 60W the ports are probably going to chuff quite loudly.

You may notice that the top-mounted handle has had the corners cut away, so the TC's feet sit in the cut-outs. The handle is around 6mm thick in the centre of the cut-outs and this is enough to stop the lightweight amp from moving under vibration, the weight of the speaker cable and the instrument cable. There were various other methods in the pipeline to stop the amp moving but still leave it easily removable, such as adding an extra plywood surround on the top of the cab that the amp sat in, but in the end this was the simplest method.

Hi Simon, I'll be rear mounting the speaker and the baffle will also be attached from the rear to avoid seeing any screws on the front so yes, the rear panels will be removable. I'll need to re cut them as there currently isn't enough space for them to fit once I've wrapped them and the cab.

Cheers

[Simon Barden]

Good thing you remembered to adjust for the covering before you wrapped it!

For reference, here's the back of my old Marshall 1x12" cab.



Hole cut in the top panel for a handle, jack connection in the bottom panel. The rear panels are just painted black with no covering on them.

When I started looking into a basic cab build, I often found known brand speakers popping up on ebay and gumtree, eventualy found a Vox 1x12 also, which had a celestion GB 25 - 8ohm and couldnt resist given price.
Still like to have a crack at building one after seeing Dedmans and now yours. best of luck with an interesting project !



EDIT: interested in any pics Stan of your cab

Celestion Creamback - $130 - still available at time of post

Its worth having a go, Think this is going pretty well considering I have no particular skills in this area, I think you have to start this by acknowledging you could probably just go and buy something pretty reasonable for the $'s you end up spending on building it, but at the end of the day don't think that comes into it, more about having something you know you made yourself. Same with the kits, of the 3 I've built/started sure none of them have come in under $600 - $700 bucks, Just don't let the wife you that :-)
