Brace Dimensions

Post by twenty2late »

I've searched the internet afar....and spent time scrolling though the forums, and haven't come to a conclusion yet:

What is a good dimension set for top/back braces for a 000 and a forward shifted drednaught?

I've seen a few good resources, but nothing definitive on them. I've got 6 pieces of brace material (4 came out perfectly quarter sawn, and 2 rift sawn) from stewmac that are ~3/4"x2"x20" and want to make sure I cut them right. Not too worried about the x-brace joint as I've found numerous ways to do it, but don't want to accidentally run out of wood for 2 sets of braces. Thanks!

That's awesome that you got your hands on those John! I'm assuming if I rip the strips into 1/4" strips than it'll produce enough braces out of the materials? Then...I can get them to the width shown in the pics with the thickness sander?

John...you're the best! I actually found a way to get measurements this morning too...based off of the templates you sent compared to blue prints from Kinkead. Question...your back template has 3/4" openings for the bottom 2 back braces, yet all of my guitars have the same width back braces, just different heights. Is that just in-case I do flat back braces for those 2?

Now...I just need to figure out how to cut them out of my bracing stock so I don't come up short on material!!!

If you come up shy, let me know. My # is in a tool for sale ad. I think I have a pre-made X brace set and perhaps a few others left over from my production days. maybe some adi brace stock too.

Ahhh...that makes perfect sense! After a considerable amount of digging in the forums, I think I found all the info I was looking for, and decided on my cuts. Looks like I actually have a little more than I need!
