That was great advice.. I am keeping the old tank. And that is that..thanks for all the pointers

Started the bracket ..waxed the mold and put three coats of no wax gelcoat...then i started with the glass I put an 2 oz choppy. Then 1708 in all corners .. then 3 layers of 1708 0/45 and on layer of 18oz biax. 0/90.. overlap all corners ...wwas wondering what laminate scheduleneeds to be

Okay i had problems with the gelcoat and resin.. After i put a layer of2oz i started to see the glass bubble a little in some place.. And another place it had pulled from the mold.. I used mold wax and then brushed 3 coats of gelcoat no wax.. I then started laying glass the next morniging.. I tilted the mold up in the back so that the front and back were 90degrees to the floor.. It was in the front that it stared to pull from mold. I braced it up and then started laying three layers of 1708 i let kick off and pulled braces... Have you guys had this happen with gel coats

post pics please. easier to help with visuals.

Hi strick i wish i could as i already layed the glass on.. It only did this when the matt was kicking.. I had already layer some 1708 tabing so i think that it was from the 1708 tabing and nothing else keeping the mat to the mold as the tabbing started to cure or shrink. It pulled on the mat. So i just put wedged sticks in the mold to hold the glass to the side and layed more glass in..we will see after we are done..
Strick how many layers are over your braces..did you put .as many layers as your sides .. Or less.. And also did the motor mount go in after the 3/8 thickness was attained on the outside.. How many layers on top of the foam/plywood. Motor mount
I will be laminating 25lbs foam core with reinforced glass kinda like coosa board but nida core, foamboard..
It is 1/2 inch so i will laminate three pieces to bring it over 1.50".. Probably vacuum bag it to back..or do you think that vacuum might pull it off the mold

glass pulling from mold
 

Okay CHECKED bracket and saw the glass is pulling from mold...got 4more layers to go .. I guess it was the heat and release wax ..bizarre

Alligators suck I had my share of them...many causes...

bracket mold
 

Eight layers of glass 7-17/08 biax 45 degree
1-18oz biax 90 degree
1-layer of 2oz mat
Will start glassing in Transom pad

have some air bubles on the last glass layer I think it was getting to hot the mold that is

I dont know anything about vacuum bagging as I have never done it so am not qualified to answer your question on that. Transom core goes in after the tub is layed up. There are 3 layers of 1808 over the transom core. What are you referring to as "layers over braces"?
