Q&A | Resonating vs Reflecting Backs, Top Thickness, Scrapwood uses, and more! 

thank you Eric. You do a great job in explaining things . it is not easy to talk to a crowd . even it its recorded .

Waxed wood strips can be used like Teflon strips. Stacking veneer strips that have been well waxed aren’t too difficult to manipulate. I use paste wax as a release agent and wipe off excess to avoid contamination of adjacent surfaces.

Building some speakers and taking in a lot of info here 👍 Ive had a plan in my head regarding the back of those speakers.. Which was to use a - granite slab I have laying around. My thought was that the speaker while resonating would be perhaps enhanced by having a very dense high mass object to push away from, I'm thinking during the back and forth movement a lot of energy must be lost to that fore-aft flexing of the cabinet as a whole given the tiny movements of the speaker driver. Now granite not being practical for guitars and low weight I see is a perk. I'm not sure what material could give the same effect, but I'm sure it could have some effect on the cleanliness of the waves. Maybe there's an optimal weight for that back panel. And it could be used not as a resonator or reflector but as a sort of launch pad.

Hi, Eric. Thanks for the video. Wanna to share my experience of thicknessing the top/back and sides. Firstly, I started with 3mm for the spruce tops, and 2.5 for the sapele back and sides. Than went to the 2.8 for the tops and 2mm for the back and sides (still using spruce for the tops and maple or sapele for the back and sides) . Everything is fine. (12 guitars are made) Now I'm going to make 2.5mm sitka spruce tops and 1.8- 2mm sapele/maple back and sides. Hope, it'll be okay. But I should say, that I make the V-bracing, not X. That's very important, because on X-bracing it's quite dangerous to use such thin tops.

❤❤ very nice video.❤❤

Question about the teflon strips? Where are they now available since LMI has closed. Also, are LMI used to have different sizes as well.
