6.5" Dyna-Sonic strainer mount hole placement, size?


Greetings,

I'm restoring a 6.5" COB Dyna-Sonic (script badge).

The previous owner had enlarged the strainer mounting holes to fit a different strainer with similar, but not identical, mounting hole pattern... So I'm going to have those holes patched and re-drilled for the proper strainer by a professional brass musical instrument repairman.

I'm trying to arrange that right now, getting a quote, but I don't have a throw yet to measure the bolt size, or distance between the bolts. And I have no way of knowing where vertically the holes should be from the bottom. Are there diagrams of Dyna-Sonic mounting hole placements and sizes somewhere?

Or would a kind soul with good measuring skills kindly measure a 6.5 Dyna so that I can place the throw exactly where it needs to be?

Hoping to do this right emoticon

Cheers!

I have seen a blueprint style drawing of a COB Dyna, with all the parts "exploded". I believe there is one somewhere on this site, but I spend about 1/2 an hour looking around and didn't find it. I think I've also seen them for sale on Ebay. That might be a good place to start. I'd like to assist but I don't want to take mine apart to get some measurements for you. If you can't find the blueprint your next step would be to get a strainer, which you'll need anyway, and place it in the proper position and get the placement that way. Good Luck.

Thank you very much for the time spent looking for the diagram!

I was hoping to line up the appointment with the brass doctor while the strainer was on it's way, but the strainer is almost here now. It'll be much easier with the real item on hand. I can get a vertical alignment of the top screw in relation to the lines from online photos, and with the strainer in hand it should be no problem.

Fingers crosse the operation will go smoothly...

Cheers!
