They are all rectangular. I will trim them. Thanks!
Yes, they're the ones. I actually use Fat Max - rather more expensive, but hold an edge for quite a while.
Thanks. Breaking down the glue was also my concern. If there is a time limit you can apply the heat without affecting the bonds then that would give more confidence. But it is unknown territory and therefore risky as you said. It's probably better to sell the guitar and buy another one.
The edge of the iron will likely be poorly dressed, so you might need to spend some time on that. Set it to take thin shavings. Practice on dummy braces on scrap wood . . in the dark!SteveL123 wrote: ↑Fri May 25, 2018 2:42 amThanks for the tip about the modified Zona Spokeshave Pat Foster! I was going to get some violin brass thumb planes from China but this looks like it will work just as well if not better. Cheaper too! Just ordered one for $7.80 with free shipping from a Walmart affiliate Blackstone Industries.
Thanks for the advice Mr.Rain! I do have 2 Hacklinger gauges that I made to measure top thickness but that probably is not the tricky part.Mr.Rain wrote: ↑Wed May 23, 2018 2:18 pmMy 2 cents I would go for a different approach, as altering the top thickness sounds super tricky to me.
Actually I did it before, I shaved the braces of a studio guitar from the soundhole (using a "finger plane", a spruce piece and sandpaper ) the original braces were very tall (5mm), shaved them down. 1st to 4mm, then 3.5mm and then to 3mm (finally rounded the bars!). The guitar was becoming louder on each "reduction", warmer and more open. At the end the result was an instrument you could play and that sounded like a guitar (not the trebly, 0 bass instrument it was when new)..
Removing the thick lacquer will improve the sound as it is a poly-coffin, making the guitar even tighter...
Watchout for RH, no finish means the changes will affect it even more (what you can perceive as a warmer tone, can be dimmed trebles in a wetter day...)
Will do thanks! I always take a few dry runs when doing something for the first time till I feel proficient.
