3 piece back measurements?

This is my old D-35 back:

Hey thanks for that note. yeah, I agree, I didn't mean to lay it out that way, it was just a rough view of how all 3 look together. I plan to do it the same way you describe and how d35's are set with the neck heel end just like in your photo. That's a beauty by the way. I also plan to use black/white/black purfling like that.

the back wedges were 6 in wide at the bottom and aps 1 1/4 at the top. that varies a little but not too much. They did this to use up the narrower brw they had . by 69 BRW was pretty much done at Martin on production instruments. Every now and then one pops up but this allowed them to use the stockpile up.

Looking pretty good. My drum sander has only about 10" of workable area so glued on the maple/rosewood/maple binding to the middle piece then sanded 3 separate sections down about .117". These plates aren't even glued together yet. I'm considering replacing the strips as the outside maple piece got a little narrow at the bottom end but eh, it might be ok. Wouldn't be hard to re-do them however. Now that the plates are sanded, it might be easier, more accurate to just to glue them in then use a hand plane and sander to bring them flush. Ok, talked myself into it. That narrow maple strip is bugging me.

The back looks a lot better to me than just the 2 book-matched plates so I'm very happy with this start.

Ok. All glued up. Replaced strips. 4 7/8” at base. Houston, we have a back. Calling it good ready to move on. Thanks for letting me share and process thru the new trick.

Just wiped with naphtha.

That looks really good.

I plan on doing something similar after finishing my current guitars. I have a piece of rosewood that is only 7" wide and some Brazilian that is 3" wide. I might double the Braz to get these dimensions.

Thought I'd come back to this post and drop in the finished guitar. Just strung 'er up this morning. Looking and sounding fantastic. Thanks for the help as always.

Very nice. The back looks great!

Wow, that’s a nice looking instrument! A good friend of mine had a Martin D35 and I have always loved the 3 piece back. Great job!

Wow, that really turned out nicely!
