I curious. Are there any formal scientific considerations for how the sound will behave in committing to the design of these coverplates or are those trial and error type decisions? And what kind of protective gear is standard for that kind of work?
My approach is fairly random, most of the considerations are 50% cosmetic, 25% ease of construction and 25% trying to copy old National proportions. I have been trying out various ideas for some years but have not discovered something that makes my guitars sound ‘better’ than I would expect. Michael M believes that National/ Dobro came up with perfect designs and there is no point in trying to better them. Some of us out here can’t help trying to improve on perfection.
As to protective equipment, I do most of my work with power tools outside and I feel only a light face mask is necessary, I ware glasses ( polycarbonate) for some cutting work. Inside I have an old vacuum cleaner that can be switched on when a dusty operation is happening. Pete
Because of that so-called perfection, Pete, Mr. Dopyera is now practically regarded and worshiped by some as God. And that is funny, ironic and unfortunate at the same time, because the man himself would never have achieved any results without his belief in curiosity, experiment and evolution.
I remembered that I have this unused fruit press. I think I might try the two bits of holding timber as linkous does, and make upper and lower moulds from silicone moulding material, then press it into shape. TT
