MemberJuly 9, 2025 at 5:53 pm in reply to: Video: Measuring Long, Cross, and Transverse Modes + Thickness CalculatorIt really is a great reference and yeah, working through the math is a thing. I have an engineering and math background, and it still took very real time to get through it. I do hope that this video and the calculators that I put up Help make it more accessible though to folks.

MemberFebruary 12, 2025 at 12:13 pm in reply to: All-mahogany Martin-1 top thicknessJust a couple of comments on this. Robbie talks about using the ‘sheet metal sound’ to determine the stffness experientially rather than from measurements.
And another option for the top thicknessing is to use the web fft software I put together as an alternative to REW and the python packages and web calculator that implement gore’s formulas in his book.
These are located here:

I used this on an electric neck and did a couple of test pieces on spruce that I had laying around.
I used the grain filler, sanding sealer and indoor finish.
I haven’t bought the more expensive light yet – but will soon.
It worked as advertised – getting the cure was pretty hard with just the uv flashlight, I ended up taking the neck and pieces outside to cure but then it cured quickly.
Like folks said it takes very little product to apply the finish. I ended up using more than necessary a couple of times.
I’m planning on doing some electric bodies soon with it and will also try it on an acoustic if it seems like it’s working well.

I actually just got this and am testing it out on a couple of electric bodies and necks (first). so far it seems to do what it claims, cures fast and hard. I didn’t buy the expensive lights yet.
