Epoxy bonding does not work.

Use SS tubes and tig weld them to the steel linear..

I already have the tubing welded by you a while ago but I want to
seal the cooling chamber

In order to get EPOXY to stick to aluminium you need to get inside
with a small die grinder burr and clean out all the aluminium oxide.
Then you need to treat it with this prep kit you get from West Marine
in Ft Lauderdale. Then it may still leak :-(

The sealing block is better and repairable with an O-ring.

Randy is making them on his NC mill.http://www.rotarpower.com/#!

Paul/
I do have the oring blocks

JEAN PRUDHOMME


Why do you want to use epoxy?
The old method of using epoxy cut the water flow through the block.
Not what one wants for good cooling.
