    fitting the tower hard top

    photo 1 shows the way we notched the top to slip thro the front tower tubes, if you look close you can see the center is filled with what was removed ll the pieces will be glassed in for final install. the 2 photo gives you an idea where the radar will end up and the 3'rd photo you can see the way the mounting style will allow the hard top to over hang the tubing with out having a two piece tower....

    Time for the yacht surveyor

    well I need to put some new photos up... I had the bertram bottom and seacocks and pluming checked by a yacht surveyor, kinda a 50% survey so I can finish up dock side.. All he rely had to say was there were no voids in the hull :cool: and to make a sticker for the factory fuel tank listing a build date. We chatted a little about how I was going to run the ac/dc system and he was on his way... I stressed it for a week but turns out my friends have been harder on me about how to build this boat then the surveyor, my friends do work on mega yachts and are well payed so there is no real surprise.

    I will be splashing in soon... I'll post some finished bilge pluming photos and pic's of the ac/dc system being installed. happy thanks giving every one:D

    While that is true, you can use a pneumatic bubbler type gauge which measures the head pressure of the water. You basically pump a little pump, manual or electric until bubbles blow iout the end which is at the bottom. Then the watter level rises back up into the tube creating pressure which is measured by a sensitive pressure gauge and calibrated to your installation. There are several of these systems around, we have a Heart setup on all out tanks feeding the data to an FT monitoring system. The other good thing about this system for fuel is that it takes all electrical components out of the fuel.

    BTW, nice job, what resin did you use for the layup?

    Thank you & Thanks for the info.. I'll have to look into that, I do need a float for my main fuel tank as well as the fresh water...

    I used a fire retardant epoxy resin on the aluminum auxiliary/bio diesel fuel tanks. I don't think it needed to be fire retardant seeing as it was a uscg approved fuel tank to start with but a friend hooked me up with the resin so I used it..... I've hear bad things about polyester resin tanks with gas/bio/svo but have been told its fine for diesel, vinyl ester or epoxy should be fine for almost any fuel.

    That's if you were talking about the tank lay up... I have pored 200 or so gallons on the boat & parts, I have used all kinds of resin they all have there place. As you may know as long as you never put polyester or vinyl ester over epoxy you'll be ok and if you need to fill more than 1/4 inch use an epoxy fairing compound.....

    one of the biggest trick I have found is, SUPER STICKY PAST made by ebond!!!!!!!!!!!!!
    this is a thickened 2 part epoxy that will hold epoxy soaked 50oz tri axil carbon fiber upside down.... it also gives you fill and can help flatten tricky lay ups and by the time you roll out all the air the slime will be raping the fibers giving you a crazy epoxy bond.

    There is also faststone after you put this epoxy stuff on you can spray it with water and rub it flat with you bare hand un cured & drys wet!!!!!

    Most of my fill I make using micro spheres or micro balloons and epoxy..... it will not crack or shrink like polyester fillers.. You can add a lot of dust for ultra light fill or keep it wet and strong.. I have a 3 inch thick piece of light fill that dryed in the mixing cup it is very hard to brake with a hammer. but its not cheep and you can't go back to polyester once you use it......

    more photos

    I try and post some new photos every night till were up to date on the project.....

    This is when we hinged and cut the hard top... I started by taking wood blocks with the hinges foot print.. the one inch mahogany blocks were glassed into the top and bottom of the hardtop then they were cut in two a 1/2 slit thro the center all the way thro the hardtop... I welded two pieces of stainless angle to the bottom of the hinge so the angle sat flat on each side of the hinge mounting aria this way the two pieces of angle act as a door jam and two 1/4 angel welded to each side of the hinge to keep it a one way deal. it adds up to 1/2 inch of stainless between you and the cockpit deck if you walk out on the end of the hardtop...photo one shows the hardtop down the othe two show it up for the firs time.... a happy moment...:)
