Glue choices for making the Garrard 301 plinth


Hello Audiogoners,
Is there anyone who has experiences on making the plinth for the Garrard?. I am reading somewhere that the choice of glue could affect the sound of the turntable. I am also reading about the hide glue is one of the glue I should use. Please let me know of what you think about it and give me some advices please.

Thank you,

Calvin

I'm not sure what the builder of my plinth used for glue (I think it was a two part aircraft epoxy) but we went with bamboo ply instead of the birch. I have heard the same plinth design in birch and bamboo and the bamboo has somewhat more impact in percussion and a slightly better focus then the birch other then that its about the same. the bamboo makes for a beautiful looking plinth as well. I would say the bamboo is some what more sensitive to what footers you use then the birch. I found the birch likes cones the bamboo likes a little more isolation I use ISO Acoustics Orea feet as the bamboo is somewhat heavier then birch (my plinth-table is close to 100lbs). 

I have pictures of my plinth in my system pictures if your interested.
Bamboo is quite expensive but worth the effort. in building. .and cutting ( it will burn through your tools fyi). I went with honey bamboo Ply.  bamboo ply is quite a bit thicker then other types of Ply also. I think the sheet sizes were 4x6 and about $100 (Canadian$ but bought from Seattle) a sheet. 

One other thing to try if you have the space is to put a small void (mine was 2" by 6") in the middle of the plinth layers i put mine under the tone arm, it can not be where your going to machine out the area for the table or arm. I filled the void with clean dry sand then sealed it in the build up. this adds some damping. note you don't want too much or it deadens the sound but a little helps with resonance in the table - plinth.
never considered ball bearings to be honest. 

I thought of led pellet's, sand and a synthetic putty we use at work for similar things but that didn't have the longevity needed. remember what ever you put in there is in there for life. 

In the end sand seemed the easiest to fill the void (and wasn't toxic) as I didn't want any open spaces I figured they could cause resonance chambers.

 if you pick sand don't get it off a beach lol buy proper dried sterile sand. 

also there is nothing saying you need to put a chamber in at all most people don't I was experimenting. seems to work, but I didn't build one with out so hard to tell if its working beneficially or not. 

our thinking was to try to mimic the idea (not implementation) shindo used with out the expense.  

just relized my system photos are rather old.
