Thanks for your offer! I'd like to take you up on it. How can I get the jig? I get to Phoenix about once every 6 months. I'd be glad to pay for shipping priority mail both ways if that'll work for you.
It's probably best to use direct email or phone about this.
My bridge is on the way back from the maker so I'd like to borrow your fitting jig. If you'll send it priority mail, I'll reimburse you for the cost and send it back the same way as soon as I'm done. If you have any questions, please give me a call: 520-603-3498.
You can send it to: Larry Klose 1116 W. Camino Monte Cristo Green Valley, AZ 85614
If you could tell me again the URL for the band you're in, I'd appreciate it. I wrote it down but that note has been lost.
I just saw you message. Give me a couple of days and I'll post more about my caul making. I actually modify ones from stew mac that are close to the radius I need but there is no reason it wouldn't work to make them from scratch.
here is a link to a thread about the caul set that Andy Birko is now offering. There is a lot of info and some pictures in it.OLF thread
I'm not sure if your looking to make a whole set or a few to fill in gaps in the typical sets. I made some originally for filling in gaps as I needed. For example Stew mac has a 7.5" and a 9" caul and I needed one in between so I made an 8.5".
Making a whole set with my method would be very time consuming so I was thrilled when Andy came up with his set. I charge $350 for a re-fret so the cost was a no brainer for me.
Calculating a progression of radius's that have an even progression and pass through important factory standard radiuses would not be hard, but certainly time consuming for me. Dave Collins took it on and did the heavy lifting for the set.
Why don't you look over the thread and maybe I can answer specific questions you have.
Are you looking for information about my technique for making them or calculating the radius progression?
The idea is to change it to solve for the radius (r) and use an incremental increase in the sagitta and 1/2d (half the width of a brass caul) to calculate the next radius.
calculating for two in the set I have, (6.8" and 7.1"), I get an increase in sagitta of .005"
So, if you could slide a .005" gauge under a caul in the set, the next larger diameter you could slide a .010" under, the next .015" under and so on.
It gives you an idea of the large number of calculations Dave did to come up with a set.
Basically, you need a lot more cauls in the smaller radius' to minimize big jumps.
