All I would say is: don't build it out of MDF like I did - heavy and dead!
Can you saw wood accurately and square? If not go to B&Q and have them saw the pieces for you. They keep 18mm birch ply but not much else unless your happy with cheap ply. If you want 15mm birch then you'll need to vist a woodyard and see if they'll cut to size for you. If you want pine, finding boards more than about 250mm wide is not easy. If at all possible look for 'unsorted red deal' which is usally a type of fir, very straight grain and very few knots If possible hand pick it. Dont be tempted to take knotty pine or you'll just be making work for yourself.
Are you able to cut dovetail or fingerjoints? If not youre going to need to dowel or screw the corners with come bracing. Use stout screws, not drywall screws. No12 or 14.
Do you want to cover it in tolex? If so you will need a hot air gun, trying to mould the corners neatly without is problematic, unless you are very very good with a stanley/moedlling knife. If you are going to fit metal corners you need to know the radius of the curve and you will need a router and appropriate rounding over cutter to shape the cabinet edges. Usually 12mm or 15mm radius. Using PVA glue will give you time when covering unlike contact adhesive which demands speed. PVA will respond well to a hot air gun, so if it is nearly dry , heat it and it will become tacky and stick just like contact adhesive.
Are you going for a cloth covered baffle? If yes you will need a staple gun (cheap manual one will do). You will need to decide before you start whether the grille cloth gets fixed to the speaker baffle or you will make a separate frame for it.
You will need M5 or M6 T-nuts for the speaker mountings. I would recommend always using 8 per speaker even though most speakers only have 4 holes. If you wreck one (with a baffle which has the grille cloth fixed to it) you just turn the speaker 45°. I think most eminence speakers have 8 holes though you only need to use 4.
I'm suer theres more to think about but I want to get this posted before the 11pm forum shutdown
Am definately getting the feeling that half way through this project I am going to re-read the posts here and think 'they were right, I should have just bought one...'
Thanks for the info.
Was going to go to a timber merchant so I could get a decent sheet of 18mm ply and probably 12mm for the baffle and back. Will try to rebate the baffle for extra strength. A bit confused on the bracing though. The cornford 2 x 12 cab I have is meant to have the baffle rebated but it also has bracing around the back of it. Is that for extra strength or some kind of clever internal volume reduction?
I have a router, nail gun and hot air gun so all set there. Think I will try and do lock joints as don't look too bad to do with a router.
Seperate frame for the grill cloth.
Still can't decide on dimensions. Think I need to go and try out a few more cabs.
I'd love it to read (like @octatonic guitar builder thread, which is still my favourite thread on here) and if you encounter any difficulties, there are folks on here who will happily step in.
