Steelnerve Posted July 30, 2009 Report Share Posted July 30, 2009 I am replacing the front beam of a Cobra and need to know what putty/resin (Stuff) that is used for packing between the beam and the hull for a snug fit. I cleaned/dug a brown/grey (Stuff)putty out to make for a new fitting. I heard that maybe resin and talc powder to make a paste would be ok, but I would of thought it would be too runny to mold and too hard/brittle when fitted to do this job. Any expertise help would be greatly appreciated. Evan Link to comment Share on other sites More sharing options...
mitchlb44 Posted July 30, 2009 Report Share Posted July 30, 2009 Hi http://www.cobracat.com/ Try calling one of the contacts - The only one I know personally is Rick Nixon (VIC) who has put together a lot of cobras! He should be able to help! Mitch Link to comment Share on other sites More sharing options...
Steelnerve Posted July 31, 2009 Author Report Share Posted July 31, 2009 Thanks for that Mitch, I must have a talk to Rick and see what he thinks. I was wondering what normal thing was for most cats.

knobblyoldjimbo Posted July 31, 2009 Report Share Posted July 31, 2009 just don't use sikaflex, one of the Mari boys did and had a devil of a job to remove it later. Link to comment Share on other sites More sharing options...
Pointed Reply Posted August 3, 2009 Report Share Posted August 3, 2009 Try this. Wrap your cross beam in contact or gladwrap, put resin on the cutout then bolt down tight. Resin will flow to all recesses. When dry remove beam and take contact off crossbeam and you have a perfect fit. No need for gooey filler !!

NixonJr Posted August 24, 2009 Report Share Posted August 24, 2009 Evan, The way "Pointed Reply" is how Rick Beams his boats - Mixing Resign with talc/q-cells to make a fiberglass bog. Once this is done and the beam has been removed he uses clear silicon (don't use No More Gap as this will shrink!) and tightens the beam to the boat. Giving the beam a watertight seal. On fiberglass cobras you may have to grind the decks around where the beam goes. The beam shape in the mold is not a perfect shape for the beam. However this has probably been done before.
