Typically, I rod ALL pieces that are to have cutouts.

I like to use 1/4" stainless steel round rod in 2CM stone
and 1/4" x 1/2" flat stock for 3CM stone

Rodding is an extra step, and it costs me more to do it
right, BUT - IT"S CHEAP INSURANCE!!!!

I'll have to check my MIA Design Manual to see if there
is anything documented...

Kevin,

Thanks for replying.

How do they attach the steel stock and does it have to be S/S also?

Glenn

here's apic of the process:

We cut a slot for a steel rod or flat bar to sit in..
in this case - it's 3CM stone that will receive a 1/8" x 1/2" flat bar stood up on it's side for more strength.

for 2CM - 1/4" round rod is used... I like stainless in case
the rod ever comes in contact with moisture - it WON'T rust...
better peace of mind for me and my customers....... ;-)

The rod is set down into the slot, then flowing epoxy is
poured into the void to "lock" the rod in place...excess
epoxy is ground off when it's dry, and the top is aprox
600% stonger (I saw a test that threw that figure out - It
may be more or less - but rodding works!!!)

hope that helps

Kevin,

Thanks for the nice photo of the process, but I have a few questions. If one is using 1/2" stock, does the groove have to be 5/8" deep, so that the S/S stock is slightly below the surface, then filled w/ epoxy resin and ground flush upon hardening? Does rod reinforcing go around all 4 sides of the sink cut-out or just the 2 narrowest sides and finally where could I purchase the stock and how long should the pieces be for a 31" long sink, 36" per side?

Kevin, I researched the 'rodding' of 2cm and found the above discussion oof 2008! Would you please tell me where to buy this rodding material and also do I put in on all four sides or just the front to back. If it goes front to back, then does it go behind the water faucet or in front between the sink and the faucet.
