Re: Stress Fractures
When I did my stress cracks I used a die grinder (small one) and a disc so that I had a ratio of about 7-10 to 1.width to depth.
Then instead of micro balloon I used milled fiber. I got this stuff for some high power rockets. It went on real smooth and I used the very slow hardener.
My buddy said that I overkilled it and said the groving out the cracks to stable material was fine and takes flexing well.It won't take long either way.I have a feeling the milled fiber is better then the west filler. West may even have a milled fiber, I don't know.
