Greetings folks,
I'd like to have a go at building an extension cab or two and wondered if anyone could point me in the direction of useful info/tutorials? Really looking for internal dimensions/structure, wall thickness to aim for (will be using hardwood), how to cut the speaker 'hole'. Tolexing not so important as will prob be oiled finish, but still handy to know.
Any suggestions much appreciated,
Adam

Thanks for the info so far. Initially it would be a 2x12" cab, but if I feel luike experimenting further, so be it.
I will do the joinery myself, and am quite familiar with the dust a router produces, having built a couple of guitars amongst other items.
Regarding cab vibration - I don't currently have any ply (well, not strictly true, but I'm not sure 4mm would be any good), but have a good stock of afromosia, rippled ash and laburnum I could use.
I am sure that there is a lot of info online, but the reason I didn't go straight to google is I find it difficult to assess the 'quality' of random internet wisdom. Whereas asking on a forum, that wisdom can be prodded a little
Cheers,
Adam
That's actually very useful, thanks Winny_Pooh. I think I was perhaps getting a little caught up in whether specific sizes (for instance, say, a guitars' scale length, but for cabs) and dimensions are important or not.
Cheers,
Adam

I'd use 15mm for the baffle , preferably birch ply, and definitely drill all 8 holes for the speaker mounts even though you only need 4, you never know if you might chew up a tee-nut. 12mm for the rear, can be ordinary ply. If you have a router and are intent on having a lacquered wood finish definitely consider getting yourself a dovetail jig. Dovetails look the dogs bollocks when stained and lacquered and are very strong, no need for internal bracing.
My Thornton amp has a nearly-dovetail joint which does indeed look the whippets wedding tackle -

Not sure I could match that though!
