Love Bills' designs - what driver are you planning on using?[/quote] It's just starting to come together. I found a local supplier of Baltic Birch plywood who's prices are very reasonable, so I'll pick up a sheet and maybe start cutting tomorrow. I'm going for the Eminence Kappalite 3012 driver, not sure if it'll be the LF or HO version [url="http://www.bluearan.co.uk/index.php?id=EMIKLIT3012HO&browsemode=manufacturer"]http://www.bluearan.co.uk/index.php?id=EMI...de=manufacturer[/url] [url="http://www.bluearan.co.uk/index.php?id=EMIKLIT3012LF&browsemode=manufacturer"]http://www.bluearan.co.uk/index.php?id=EMI...de=manufacturer[/url] both are the same price from Blue Aran. Bill used to recommend the LF version but my plans say the HO is the one to go for. As soon as my registration on the BFM forum is confirmed I'll ask why! I intend to build one 1x12 without tweeter array first and see how that goes (I don't really play slap bass so the tweeters are not necessary). If it's a success then I'll do a second one with tweeters to stack together. I was thinking of an OMNI15 TB, but cost is a major factor and it seems from reading the forums that 2 Jack 1x12's are perfectly adequate for my needs, that and the fact that the TB is the size of a wheelie bin!!!!

gilmour Posted November 23, 2010 Share Posted November 23, 2010 I'm going to sell my Jack 210's soon - because they're to loud for what I need! I really like Bill's designs for bass. Always sound good, and surprisingly loud. Quote Link to comment Share on other sites More sharing options...

[url="http://www.pbplywood.co.uk/"]http://www.pbplywood.co.uk/[/url] £29 for a 8x4 sheet. I ended up going to Howarths Timber in Bury and got a sheet of decent looking stuff for £17, it's not birch but it looks ok. If I was going with a wood finish I would've lashed out on the better stuff. Wickes and B+Q want £30ish for tatty looking stuff and B+Q only had 18mm Birch ply @ £56!!!!!!!!! Cutting and pics. tomorrow! Cheers, Mick. Edited November 23, 2010 by Big Mick Quote Link to comment Share on other sites More sharing options...

Not particularly cheap but it's good quality and incredibly light. Wasn't really sold on the J10s though, at least for PA. Quote Link to comment Share on other sites More sharing options...

JTUK Posted November 24, 2010 Share Posted November 24, 2010 I love these build threads..the end product always look at though you would buy one on cosmetic quality alone. The effort might be amateur.. ( I don't mean that in a harsh way ) but the finish isn't, normally. Some of the better DIY cabs I've seen Quote Link to comment Share on other sites More sharing options...
Big Mick Posted November 24, 2010 Author Share Posted November 24, 2010 The bits! Some more cutting will be done after tea, pics. later. Cheers, Mick. Quote Link to comment Share on other sites More sharing options...

Cheers, Jon[/quote] Well you can start right here! got some cutting done tonight, most of the big panels are rough cut (it's been a while). Cunning use of V-drums monitor. Note extra floodlight on workbench (also doubles as a heater). Some panels! Baffle plate marked out ready for tomorrow. I intend to cut as many panels as I can at the start to avoid having large bits of plywood everywhere. Cheers, Mick.

Big Mick Posted November 26, 2010 Author Share Posted November 26, 2010 Got the baffle plate cut out. Note to self........ freehand routing is a bad idea! Next time I'll think things through beforehand. Nevermind, once it's behind a grille and painted black it'll be fine!!!! On a more positive note, I'm making a circle cutter for my router to help with the driver spacer and phase plug pieces. Cheers, Mick.

ShergoldSnickers Posted November 26, 2010 Share Posted November 26, 2010 Hope that sign on the wall says 'empty' and not 'numpty' Looking forward to this - Bills designs are just so different to everything else out there. At one stage I was thinking of a Omni 15TB, but tools and talent in short supply. I'm quite happy to sit back now and watch other people build things. Hope it turns out really well.

Big Mick Posted December 4, 2010 Author Share Posted December 4, 2010 Feeling much better today thanks. So, I measured the inside diameter of the driver gasket, 11 1/16" then marked out the holes to mount the driver using a 1/8 - 1/4 jack adaptor to push through the holes in the driver frame. Phase plug. Found a proper block plane at the Mother in Law's. Quick sharpen of the blade and it works really well. The throat under construction, I screwed and glued these bits together. Throat assembly glued and ready for fitting to the baffle. No screws this time, just a bag full of loose change! Cheers, Mick. Quote Link to comment Share on other sites More sharing options...
