Looking for 8mm Carbon Rod

[Meniscus]

On mine, I laminate a piece of aluminum tubing inside the carbon, and use a piece of brass tubing around the outside where it installs into the sponsons and into the tub...

You can see some examples here: http://www.offshoreelectrics.com/for...ead.php?t=6977

Thanks Darin, this is very helpful.

Pretty close. 8mm = 0.3149597". 5/6" = .3125"

8mm ~= 5/16"
