    i would have done cpes if it wasnt so high and if i could get it local. Sanding the wood without a mask was a mistake i will try and take some pics later.

    damn still more sanding. i got the outer stringer where i want it but i still gotta sand the bildge so i can put the inner in too. Bad part it i roasted the 7" sander now i gotta get another this small one isnt cutting it...

    Did you guys cut/sand the bottom of your stringer to fallow the slant in the hull or did ya'll leave them mainly straight and use the cabosil/epoxy to build the platform between the hull and stringer?

    cabosil is a nightmare. Im glad i did the outter stringer first, didnt have much luck. I have a .350-.420 gap that the cabosil filled. I dont know what i want to do about the main. I dont know if i want to try cabosil again or use the PL stuff. I bought some PL stuff the other day but decided to try the cabosil again. At this point in not in a very good mood.....

    Ben- Sounds like you need to get a pencil and paper and start drawing a plan .. my thoughts are always scattered when i take on big projects ... lol trust me it sucks ...

    But on the HULL ANGLE i got 21 degress on the main stringer from the front to the start of the motor area , and i used a 7" resin pad 24 grit to shape the rest ..

    Now on the cabosil .. where did you get yours from ? ARE you using epoxy ? how much are you mixing up in one batch ?

    Go get you some 1/4" foam blocks to set the stringers on and then bed from there .. Keep on truckin bub .. the fun part just begun !:L)

    It was a bad weekend lively i had a situation that came up saturday that took alot of my time and my thoughts and when i finanlly got back to working on the boat i was so scattered in my own thoughts it wasnt even funny. But oh well. I did put the main one in also and i used PL on it. I am going to have to go back and do some sanding/filling before i can glass it. I had to have more gap between the hull/stringer than i wanted but i guess thats what heppens when you got your mind someplace else and try to cut lol. It should be ok cant be anyworse than what i have seen from the factory so far. I will attack the other side alot different now that i know whats going on. I just had so much on my mind this weekend i prob should have just left the boat alone but i drove the 2 hours home to work on it so i couldnt justify not getting anything done.

    Btw will 3/8 gap between hull/stringer in some spots be ok? i know its a bit more than 1/4" but what can i say im not a wood worker lol

    i am using opoxy. I mixed up 32 oz of resin with 16 oz of hardener and what every amount of cabosil it took to get a peanut butter texture. I bought it all from uscomposites

    well from my understanding on the epoxy cabosil is not what u need to use ... it works better with poly than epoxy ... and if you got a 3/8" gap just fill that void in with PL and put some sand bags or at-least 100 lbs of weight overnight and let it set up ... don't worry to much on making an absolute perfect cut ... lol cause it wont happen lol trust me ... i had some areas i wasn't happy with and what i did to correct the issue was fill and pack with PL . .... Also on the peanut butter mix up ... they say epoxy takes more to thicken the resin , cut some chopped strand mat with some good scissors into some small almost powder strands and throw those in there also ... if you got questions text me 817 996 3051 ... that PL is some tough stuff so don't underestimate it i checked my boat 2 days ago and with PL as the bed and two layers of fiberglass .. they are solid as a rock !! use that acetone ! good luck man

    Once you start to tab and wrap the wood stinger in you will feel the strength of the epoxy and fiberglass cloth. Enough layers of epoxy and cloth makes the doug fir just a good form for your rock solid fiberglass stringer! Look on the sites of tabbing in a stringers, fiberglass can be angled and overlapped for no worry ever amount of strength.
