He doubles all of the module braces to 1" thick so that he can come in with a Forstner bit and make a nice little pocket for the screw. A really nice idea I might have followed had I the patience to cut out another 16 module braces. But for my first DR I decided to go with the Nacelles as Bill spells out in the plans.

It also requires a large drill press, you can't do the job freehand with a drill. That's why this method isn't in the plans, as very few members would have a drill press with the required capacity.

That's astounding, both time wise and result wise

Thanks Grant... I'm really having fun with this.. With about 20-30 more cab to be built I gotta make this faster and easier for me but its great practice just in case I make this hobby a business

This progression onto Club #2 is mind blowing Bob, you've certainly got some kit, a bloody industrious mind and the skills to get results.
With your ruthless efficiency and impressive resources put together with Bill's world class designs and knowledge I could envisage BF Loudspeakers becoming the next PK or Funktion One
However, Bill is just as likely to be happy selling world-class designs for a handsome reward to the machine that is Pro Audio consumerisim, which enables him to sell us mere mortals superior designs for the price of a weeks worth of Espresso's!
I imagine Bill as 'The Pro Audio Philanthropist' for the everyday man.
Bob' I vote you change your user name to IKEABOB! You've got the Designer's intent on song, whilst developing the strategies for repeated, efficient construction with IKEA like implementation.

So do you have a bit changer or are cutting the angles by hand? I gotta tell you this is killing me.

Beautiful as usual...I'm so jealous.
I'm sure i don't want to know, but that CNC rig had to be 15/20k?
Oh well, even if it was 5k my wife would kill me.
Keep up the great work, and thread!

Thank u Titanium for the kind words.. love the IKEA reference lol.. Ive been building speakers for 20+ years but nothing to push me to get overly creative until I started building Bill's designs.. Horns are just so much fun to build and allows me to do what I love most. I've always been that guy to figure out easier ways to speed up and perfect production.. Although I give props to Bill with his ingenious assembly procedures as there is really no better way if you are assembling 2-4 cabs..

No Leland I cut with straight up or down cut bits only.. The cnc parts are cut to exact size then I just run the part against a sacrificial fence with the blade buried into it at the appropriate angle. That way I still keep the edge the cnc has already cut and dont have to do any measurements..
You can see in this pic how I put the cnc cut edge against the sacrificial fence and the blade on applies the angle to the edge without changing the actual dimensions of the part..The larger pieces I do on my slider for ease..

Thanks howiez.. you are pretty close, I figured all the money I save building my own cabs it was a great investment.. I actually ordered another one since my work load is drastically growing, and Im seriously considering making it a business.
