6v6 Posted January 14, 2017 Share Posted January 14, 2017 Interesting build! I think covering the cavities and making them airtight will be enough to fight feedback (thinking of an acoustic guitar soundhole bung which works by sealing the cavity not filling it) but I doubt foam inside would do any harm Quote Link to comment Share on other sites More sharing options...
HowieBass Posted January 14, 2017 Share Posted January 14, 2017 Maybe you can put a little 'time capsule' inside one of the cavities? Quote Link to comment Share on other sites More sharing options...

Andyjr1515 Posted January 16, 2017 Author Share Posted January 16, 2017 (edited) Thanks, folks Loads more sanding to do but the finish is basically off. Decent bit of wood Just gluing on the covers Edited January 16, 2017 by Andyjr1515 Quote Link to comment Share on other sites More sharing options...
Low End Bee Posted January 16, 2017 Share Posted January 16, 2017 [quote name='JPJ' timestamp='1484416880' post='3215361'] I have also heard of filling chambers in musical instruments to fight resonance and feedback. [/quote] I briefly owned an early 60s Epiphone Rivoli that was stuffed with old newspaper in the cavitiy. Took forever to get it all out of the f-holes with a bent coat hanger. I believe this was fairly common practice on semis. Quote Link to comment Share on other sites More sharing options...

Harryburke14 Posted January 16, 2017 Share Posted January 16, 2017 Its strange to see how different and pale it looks without the varnish. Cant wait to see it with the veneer on now though... Quote Link to comment Share on other sites More sharing options...

pete.young Posted January 16, 2017 Share Posted January 16, 2017 I've seen Kapok used to achieve the same effect. Quote Link to comment Share on other sites More sharing options...
Andyjr1515 Posted January 17, 2017 Author Share Posted January 17, 2017 Covers on and sanded, a little more off the back and we are down to 4lb 12oz If all goes to plan, I should be able to get the top veneered tomorrow. Quote Link to comment Share on other sites More sharing options...
Si600 Posted January 17, 2017 Share Posted January 17, 2017 Is it tomorrow yet? Quote Link to comment Share on other sites More sharing options...
Andyjr1515 Posted January 18, 2017 Author Share Posted January 18, 2017 It's tomorrow, Si600 Many of you will have seen me do this before, but basically, this is my veneering kit: I actually use an old R/C modelling heatshrink iron but a standard domestic iron will do just as well I always take an impression of the screw holes, etc, so I can find them again once it's veneered: The PVA is applied to both the body and the veneer and allowed to dry. The little spritzer is to give the back a light mist of water to counteract the bending. Here is one of the halves drying: ...and then it's ironed on, starting with the centre-line and making sure it doesn't drift: I cut some of the chambers before I add the second half. Makes it easier to find them. I iron round the edges to make sure, when it's trimmed that they are well glued. Note that, as long as the bend is in one axis only (like the arm-relief), the veneer bends quite readily: And here it is, rough trimmed and waiting sanding and smoothing out of the join-line, etc: Quote Link to comment Share on other sites More sharing options...

Andyjr1515 Posted January 19, 2017 Author Share Posted January 19, 2017 I know this is a bit of a Marmite issue, but I LOVE this... I'm putting a subtle burst into it, but this is the base stain: 2 Quote Link to comment Share on other sites More sharing options...

scrumpymike Posted January 19, 2017 Share Posted January 19, 2017 Good grief Andy - anybody would think that you actually ENJOY doing all this!! Seriously though, I've been following each posting like some addicted 'soap' fan - can't wait for the next episode! The chambering question is an interesting one and I guess the key is 'control'; you can obviously engineer cavities to enhance the final sound but on an unknown, one-off project like this the safe bet is probably to in-fill them.

Andyjr1515 Posted January 19, 2017 Author Share Posted January 19, 2017 Thanks, folks! This is the burst shading - aimed at emphasising the starburst within the figuring. Forgive the poor light...: The figuring will enhance as the varnish coats go on, but I think it is enhanced by the stain also: Quote Link to comment Share on other sites More sharing options...
