Build the first DR200 stage by stage and try and figure out the inverse of what you have built. That realisation will produce the necessary jig you need to have for the next 7 DRs.

The jigs I have are ( shared ) IP and my construction methods vary from the plans so sorry I cannot post them here. Suffice to say, if you follow what I've mentioned above, you'll figure it out.

All the best

Search old posts. Several useful jigs have been posted openly.

I am currently building 6 DR200's and 2 DR250's. What has worked for me in these builds is to make multiple parts at the same time. Once you have stops/fences set cut all the parts at the same time. Doing this saves a lot of work and ensures that all the speakers turn out exactly the same. Just really think about what you are doing and double check your setups because an error would be multiplied. For parts like the horn sheaths that have to be fit I made the first one, checked the fit on the other speakers and traced it. This saved a lot of time fitting the panels. If you take time to think about what you are doing instead of rushing ahead full speed things will go smoother and actually faster. I did not make any special jigs other then for the tweeters but I also use a cutting table that so flexible with setting stops and holding/positioning materials that it basically makes its own jigs.

I am doing T39s with the 1 piece brace for the first 3 folds of the horn. Once I got the first brace properly measured and cut, I traced the shape out on a few pieces of ply, stacked a few more pieces underneath each of those, screwed them together where the saw wasn't going to cut and went to town on them with a 1" ship auger (inside corners) and a circular saw (very slowly, using a sled). I kept them screwed together while I drilled out the throat braces and the corners of the cutouts on the other 3 sides.

I hope some day to make another batch of 4, so I'll keep that brace template. I'm also making a 2' long saw sled for each angle cut in the T39. I make it out of a 1' x 2' chunk of 1/4" BB, and glue a 1" strip of 1/4" ply down the middle for a fence. That gives me room to clamp down the sled without interfering with the saw.

Pretty much the same thought process will be at work when I start DR200s. Set up a sled for the angles, measure and cut a template, then duplicate the template as needed.

However, for smaller cabs, it's possible to create assembly jigs. For DRs, I think that being able to glue up an entire baffle/throat/throat support assembly would save a lot of time.
