Plinth to armboard interface Garrard 301 plinth


I’m re-doing some things on my Garrard 301, adding another arm board and redoing the current one. was wondering what people are using if anything for interface between the arm board wood and plinth wood. I could also use a metal for the arm board if that’s better.

I was using a small bead of blue tack (ok the stuff i got is white but the same idea) between the arm board and plinth for a more even connection and maybe some isolation, then screws. Some one mentioned its better to have a more solid connection. I have though about a hard rubber maybe as a gasket type of idea, or should I just screw it down wood on wood. metal on wood etc.

Has anyone experimented with this?

The best thing by far to use under a nice massive stiff table like yours is a set of Black Diamond Racing Cones screwed into Those Things screwed into the base.

I believe you tried everything to say the simple cones are the best? 
But this is what everyone has by default, normally

Do you understand what is preumatic insulators such as AT616
I don't know about any similar product on the market

Even Raul has been using them under his subwoofers (good idea) where the cones are most common solution. 

Actually the cones are what we would like to replace with a better things such as Pneumatic AT616 or something different like Stillpoints for improvement. 


  





What do you mean, "the simple cones are the best?"
Where did you get that?
my temporary footer set up is a steal cone sitting in a brass disc with a dimple with some very thin (1/16") sorbothane pads under each brass disc. this has been good but not the best as it floats and may not be that stable specially if bumped. 

I've tried a  softer footer and I found the sound lost some focus, the cones seem best so far but i'd like a little more isolation if I can.

 thanks for the suggestions. I will look into the links. 

My footers sit on a 160lb, 4" thick granite slab. that sits on a three legged Lovan stand.  I have about all the mass I can take with out it going through the floor (ok exaggeration). 

I can not wall mount in my current condo-loft unfortunately but I'm in a steel and concrete building that's also diagonally braced for earth quake resistance so surprisingly stable.

I know that cones are not the best for turntable, but what you have posted in this link is cones ?

Exactly. Simply search audiogon for feedbacks about those AT616 pneumatic insulators for tables up to 130 lbs (on 4 of them) or heavier table if you can add more AT616.
