Spider cracks around pole bracket

I don't get it. I just reinforced under my pole bracket (UMI) and now there are spider cracks around the base of my pole bracket close to the corners. The cracks are bad enough to feel rough when I run my fingernail across them. It looks like the gel coat will flake off if I don't do something.
Would it be from over tightening the nuts (which I don't think I did) or from using the stock backing plates? Or do they all crack there?

I lay a layer of glass overtop the bracket mounting area and run it into the hood channel. Only 1 layer of 12 oz. You also have to sand it smooth (take down the biax threads) once cured.

Although it may only be 1 layer, its purpose is to prevent the crack from going further. It also stiffens some, although not much. More if you do put it into the channel, be careful though as the hood seal will need to reinstall and you don't want a big buildup preventing flushness.
 
did you run the pole tight now that you swapped over to the umi bracket?
that may be a reason it would do that
there is a big load once the pole is tight

If Mike doesn't want or need it I'd be thrilled to get it. I got a 24-7 bracket and I need a backing plate for it. I don't want it if Mike needs it though.

I didn't torque it down real tight. Just real "snug"

Wait, what? So you aren't running a backing plate currently? If not, that's why it cracked. It doesn't take much flex to crack gelcoat.

Technically I was running backing plate. Those cheezy stock ones.
I installed a full backing plate along with the stock backing plates. It should be good to go now.

Mike..I have a NEW Xmetal backing plate....pay shipping and its yours...

its a dual breather style, so you'll just have to mod it a bit..

Thanks Scott but I made mine work already. Did you get my PM a couple weeks ago?

I reinforced with 5 layers of 1208 biaxial and one layer of 6.5 oz carbon fiber, and I have had no cracking whatsoever...

Did you run the reinforcments over the pole pad area and down the sides of the top deck?

This tends to lock the pole mounting area to the side of the top deck for added strength... If you do just the pole pounding area, the cracks just find the next weakest area to live...

FWIW
