Re: Having trouble with target plate thickness calculations

My recommendation is to have one cell with the measurement you want to use and another cell that converts your measurement into SI. You can quickly check the conversion is ok as you create them with easy numbers e.g. 1000g coverts 1kg. And then have your formulas draw the data from SI cells. units t...

Re: Frets causing back bow

My fret saw is 0.5mm, my fret tangs are 0.5mm wide so why when I install the Frets do I get a back bow on my fretboard I wonder? I'm guessing that the 0.5mm measurement doesn't include the barbs (or the frets would just fall out). The barbs will force a bit of back bow, especially if you're frettin...

Re: Shines hardened shellac - ratios

Hi Bob, The ratio of alcohol to shellac isn't significant. A 1:4 ratio just gives you a two-pound cut which is a good practical bench cut. After I mix a bench cut I will then cut it down further with additional alcohol depending on what I am doing. I french polish with something more akin to a 1/3 t...

You could also try Pete Curly. I think I saw on IG he was prepping for a yard sale so may have stock handy.

Re: How to finish a white lute?

I'm with Martin, FP is not that hard just a bit of a learning curve and the real pain is the pore filling. It's basically just wiping on shellac, levelling and buffing. If you're going to go with satin oil finish both tru-oil and osmo easy to apply. I much prefer osmo feel under the hand.

Re: Curious about a mode at 146-ish Hz

Interesting that it is centred just to the right of the bridge with nothing else going on. Is it possible you have a loose brace in that area?

Re: Epoxy, brushes, CF tow, oh my!

Hey Joel, we've used Westsystem and Botecote. I'd say the lower the ratio the easier it is to deal with in small batches so Botecote's 2:1 is a bit easier to measure out than the westsystem's 5:1. Botecote also has a longer open time about 30mins and if you need more you can add some TPRD. We use ch...

Re: Indian Rosewood Bridges coming off Cedar and Pine tops

But Martin is known to sometimes tend towards overkill............. You're one of those guys who puts up photos of a freshly clamped up top...with gaps between the clamps big enough to drive a car through!!! If you can see what's being clamped up then you don't have enough clamps!!! I only worry it...
