I purchased a dozen tops from the last of Shane's logs, and they weigh in at a very low S.G., down about 0.32.
I know they were popular, and wondering how people got on with them?
And I would be interested in the final thickness people have used for medium sized guitars.
I'll be testing them using deflection testing and Gore's plate frequency methods anyway, but judging from density, they may be 0.12"+

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Hi Colin,

I am finishing up 3 guitars from Shane's "Swan Song" batch, Was just remarking to a friend what beautiful rays these perfectly quartered tops exhibit.
This was the first batch that I "cooked" in a 200 deg oven in a frame for an hour.
After cooking, using Gore's plate frequency method the target thickness ended up at an average of about 0.105"

The last top from that batch I used for a 00 had a density of 375 Kg/M^3 and I ended up with .107" for target thickness.

I do have Trevor's books but haven't gotten thought them yet.

Does the target thickness take into account the width of the guitar?

How wide was .105 top guitar for you Robbie?

Cheers,
Danny

Yes. Both body length and width (a and b in Robbie's chart).
