yeah it was no fun ! and im still looking at wedge designs trying to figure it all out and if i can design a sturdy enough transom to hold that amount of downward force ... but thats just farts in the wind for now lol ...
This hull got quite flimsy when it was all de foamed and ribs were taken out , I put 4x4s and 1x4s on top of them to support it better while im working on the stringers ..
Question : when grinding , what is enough ? and what did you use for the motor and trans mounts ? i see salty put 4x4s but i was thinking of a 4x6 and cutting to shape , cause mine are 4x5 in the boat now ... , i plan to get one side out this weekend and start grinding , I took as many measurements that i could , but with a boat nothing is plum , level or straight lol , so Im just hoping for the best ...

Congrats on the foam removal - that's a big milestone.
Grinding - I went ~6" either side of each stringer. I left a lip of the old glass for reference while cutting new stringers & then ground it down just prior to bedding each stringer.
Mounts - I used layers of plywood on end with glass between each layer, but most others I've seen are a combination of cut 4x, 2x, and ply. Take lots of measurements, make lots of marks, etc. I made some cardboard templates spanning the bilge and mounts, but even then I ended up with my floor 1/2" high? While it's best to get it right the first time, "modifications" with wood and glass aren't too big a deal.

I am thinking of dropping snap lines to help with the deck height or at least give me point of reference ... But im also doing one side at a time so i can make cut's one time and one time only ... The only thing i am sketchy about are the front angles ... how hard were those for you ?

one of the nice things, if you can call it nice, about rotted stringers is that the wood falls away from the fiberglass skin. keep the skins. cut everything as close to the hull as you can. do the same for the engine area.
strings make good reference points but they get old stepping over them. i spray painted some reference points in the middle bilge channel. it was all eventually ground away by the time it was painted...front of engine area, rear, cutouts at front of dog house.
grinding 6" on both sides of whatever you're glassing is good. don't skimp down to 4" ;)
i like that there are no right angles, level lines, or anything plumb. just slather some more glass and resin in there and it should be fine.

Salt - thanks for that write up , the stringers I'n boat are still pretty much I'n tact , so will see lol ,
What kind of wood did you use for your stringers ? Oh and check out somebodys nice wanna be repairing

Grinding...as has been said 6" is good. If you're wondering how deep you should get through whatever is there on top of the hull to the hull itself. You'll be able to tell...get's smoother and somewhat pink/orange color.
Engine mount area...I built it up using two 2x4' stacked together plus a layer of plywood then put the outer layer of plywood on after that.

OB- thanks man i was bout to ask how deep lol , I went and got some resin pads 26 grit , flapper disc 40 grit , sawzaw blades for the stringer removal this weekend .. Im only doing one side at a time .. .. Man they really did a crappy job glassing those stringers , i found all kinds of exposed wood with no glass what so ever ... so if my plan works out like i have it .. ill be working on this thing every weekend till its summer time lol ..
-
Yeah, I think everyone that has done a rebuild has realized that the glassing Supra did could be better. I'm wondering if it was a decision to be able to produce these boats at a more reasonable price, a decision based on cost / benefit, or an ignorance of better methods that might be more well understood now.
-
well i got one side cut out tonight , that wood was all rotten !! man im so glad im gutting this boat now , the outer little stringer basically fell apart after i cut it lol
I bought this cool scraper for my sawzaw so ill try that out in the morning , post pics tomorrow .. Thanks for all the help guys !!!!
Ok so here are some pics of the cutting http://i1189.photobucket.com/albums/...6/572b34d3.jpghttp://i1189.photobucket.com/albums/...6/d39d9f38.jpghttp://i1189.photobucket.com/albums/...6/dfbd6418.jpg I got into it a little too deep I'n some areas but nothin that poly and mat can't fix ...
Question : around the driveline hump , I wAs grinding 6 " from stringer and ran into looks a grinds like bondo or pudy , did one of y'all reglass this area ? If so how did you go about it ?
