I keep telling my wife our next vacation needs to be to your other night club, so one day I WILL BE THERE! or not... if the department of war and finance shoots me down. But still, I think I can speak for us all when I say: "I am in awe of your system(s) and build(s). Keep up the pics!"

Thanks Baja, if you happen to make it my way just let me know bud.

Today I did the part I hate the most... Cut PVC! Gets all over the place.. I did however modify my table saw jig to work on my band saw instead.. So much faster since you can cut the PVC in half in one pass, but more importantly dont have to worry about blade pinch on the table saw.



and plenty of extras..

I'll have to give that a go. I just acquired a band saw. Did you use a re saw blade?

It works great Leland. Give it a go you won't turn back.. Also no need for a re-saw blade, it cut perfectly straight with out it.

One day I hope to be good enough at woodworking just to understand what you guys are talking about

haha Its never ending for sure.. I even have to use google now and then to clarify lol..
Today I made the backs and added some brownie points

I got all the parts cut up for the compression driver module today..


I also cut up these helpful little jigs to hold the little parts while cutting the angles.



Unfortunately I have to look over my measurement since the horn parts seem to long.. Maybe the was intended and you just sand the rest off??

+1. Read the plans!
The ends of the top and bottom reflectors will overhang ends of the sides, while the
middle reflectors will come to a point past the middle of the sides. Sand the point
of the middle reflectors down to flush with the leading edges of the sides; do the
same with the ends of the top and bottom reflectors.

Bob's not going to like that. For us it's a quick 5 mins with the sander. For him (and his squillion cabs) it's a major roadblock!

I guess, like many others, Bob should have read the plans more thoroughly and he would have foreseen this issue. You can lead a horse to water, eh??

Anyone seen my coat?

Ah, but with that machine he can make a test assembly, measure precisely how much smaller it should be, and build a precisely fitting part for the next (dozen) cabs. When you can cut wood with 0.001" accuracy and repeatability there's no need for "sand to fit" like there is for the rest of us

With Bob's track record, he won't sand....

He'll make a trick table saw jig and carry on as though nothing happened.

Hahaha thanks guys.. although I can be guilty of not reading instructions but this time I did, unfortunately I did neglect to refer to sketchup to get proper assembly All good now I just had the horn sides upside down..

hahaha Bob! after I JUST told you I made that exact same mistake on my ot212 build.

You guys know me to well lol.. Ive since re-cut these parts with some modification to expedite these.. I basically dado all the mating surfaces and increased the size of the cleats to help hold the little pieces straight and square while tacking together with brad nailer. Now I can get the brad nails plenty far enough out the way when it comes time to mill out the pocket holes for the module mounts.


I will however keep this one for my go to reference module while assembling them..

Woah! those braces are massive!
