1970 d-18 patch

    Hey!

    I have been working on repairing a d-18 that had a large hole in the side. I glued in a backer, cleaned up the edges and after a few attempts got a patch glued in and leveled. I have been testing finish on some scrap but am getting lost in the woods. In my tests I am doing most of the color in the grain fill. Does anyone have tips on how to start touching this up? Thanks!

    Tell me about the grain filler you are using ?

    I have the stew Mac water base grain fill in neutral. So far I have only experimented w the stew Mac stuff. I mixed some up and used tobacco brown primarily and some vintage amber and a micro dot of red. I did buy the Nazareth stain as well, it seems like that is tobacco brown with some red?

    I also have 4f pumice that I have used tru oil with in the past for pore fill. I could bust that out and experiment with it.

    I did a repair on this Martin and had to sand the entire side and refinish. I found this was the best way for me to get a good result. I could have tried spot finishing but I’m sure I wouldn’t have been able to blend it that well.

    Corey, wanted to add. The degree of difficulty on this one is high for mahogany. Light color, looks pretty chatoyant. When you are making up your test boards, I would include adding some light dye to bare wood. I’m thinking vintage amber with maybe a micro skosh of medium brown. <transtint.

    In my experience, it’s much less effort to refinish the entire sides than the hours invested in blending this patch. The binding provides a clean edge between finishes to mask any subtle differences.

    btw – very nice work on this patch – looking great!

    The patch took three tries total, it sure was tedious! The touch up is something I hope to learn more about as my previous attempts in the past were pretty ugly. That being said if it gets out of control I will consider the whole side (I could use practice with that too).

    Luckily this is a guitar I bought for practice so I can work slowly on it.

    I really appreciate your insight! I hope my work will be as good as yours one day!

      Now that I look at it, try adding a micro skosh of blue. There seems to be a bit of a magenta quality.
