19 6 new gas tank install begins

[Skoot]

Its official name is the "DAM anti-siphon valve"  

As for the 5200, I lightly scuffed the areas with sand paper before applying the 5200, seem to work just fine.

It was a good day in the garage.

I started by abrading the tank where i will be adhering the FRP.



Then gave it a cleaning with xylene.



decided I didnt have the temp or time to work the 5200, so instead i decided to fill all the holes with six10.

I had a ton of screw holes in the coffin lid

I had a ton of old stripped holese where the mahogany rail was secured.


Other places with holes



I had a bunch of cheaply covered holes from an old transducer. I drill them out, sanded them, and filled them



i used some of the epoxy to seal around thu through hull fitting hole and screw holes where i will be re-installing the new one.


i decided, since i had all the equipment on hand, to remove a speed sensor on the port side.  if i decide to re-install it, i will add it to the transducer mounting board I am install on the starboard side.


the six10 says apply at temps over 50. i applied it at 60 degrees , but 6 hours later night hit and now its in the forties.  Anyone know what this will affect.  

I had a little time left so i decided to take out the cheap ground post bolt that was in place and replace it with a new bus bar for ground collection.  





I lubed everything with electrical contact grease on both bars.


Thats when I discovered that my "fuse holder" was wired.   I really thought it was a fuse holder, but on closer inspection it is a power source for something and a 20 amp fuse


Does anyone know what for

sunday its gonna be in the high sixties, so i will be breaking out the sandpaper then gelcoat for the epoxy holes; 5200, 4200, and maybe I'll get to the 4000UV.

[slvrlng]

Are you sure the gelcoat will stick to the 610 epoxy?

[imonna 19 6]

Crap. :x

Your reply got me to do a websearch and now i see the prob. West says it will take the gelcoat, but spectrum says the gelcoat wont take the epoxy.

great. :(

So i am really only worried about uv exposure  on the some  spots on the transom and deck.  All the other holes will be covered by the console or mahogany opr the transducer mounting plate.

I still have the package of spectrum gelcoat. TO Be CLEar, can i use this on all the nicks I have in the hull of my boat (was the boat originally gelcoated over polyester resin?    





and this one


so I need a small amount of paint (less than an ounce) that can go over epoxy and the surrounding gelcoat on this area for uv protection.  Note there is some antifouling paint in the area too.


What paint  do i buy for this?    

[slvrlng]

Bill, check your PMs!

Hello all,

So I just got some great help from Slvrlng.

He explained the process of removing  the epoxy from the transom holes and redo then with Bondo glass, which  can then be gelcoated with the spectrum gelcoat repair kit.  I did some quick research and it is probably going to cost me about as much to do that as it is to get some epoxy adhering paint, so I am left with a decision as to which way to go

So i guess the deciding factor is, which makes a structural more sound and watertight repair, Bondo or epoxy resin.  

I have easter plans at 3 today and a very long week of work, so unfortunately whatever i do wont be until next weekend now.  i figure I can decide what to do by midweek and get the supplies before the weekend.

Thanks in advance
Bill

Man that was a long week.  

So i finally have some solid time to move this along, got my (hopefully) last shipment of supplies in today and am moving forward.

I have two fittings going in.

The new vent and the replacement thru-hull drain for the middle fishbox.  I was uncertain about the material around the lower thru hull hole so i wetted it out last weekend with a little epoxy to seal any core.  Then I fabricated some backer plates and some matching plugs to hold them in place for the initial cure, then once I could  work with them without too much mess I installed the fittings with a light pressure to seal up.  They came out very solid and well sealed.


Vent fitting hole


Dowel for initial hold


4200 and backer plate


initial set



Tomorrow I 4000UV the fitting in and secure the vent hose


The Thru-Hull drain

Old thru hull drain


inside before sanding


The old backer plate, a piece of 1/4 plywood



The new backer plate with 4200 bedding



The thru hull hole after intiial cure and removal of plug


I also did the 5200 bedding for the FRP strips.  didnt go as smooth as i hoped, but got it done right eventually.  took 3 full tubes.  I followed the pascoe method first which was to cover the entire surface of the FRP with 5200 and then press it onto the tank, but the tank surface had a slight mild wave around the baffles, so I had small space in places.

I ended up putting a full covering on the tank as well, pressed the two together, then ran a bead of 5200 around the entire edge of each piece.  came back an hour later and touched up a few spots and its been curing since last Friday.  Lots of humidity, but its hard to the touch now.

Abrading the tank


taping off the sections


after 5200 applied, but before i cleaned up the splotches with solvent


Tomorrow i secure the deck fill, vent and thru hull, then pre-fit the tank so i can hoses cut to the right size.

Byu Saturday I should have the tank bedded in the coffin and starting on final install of the hoses.

Nice work  

[imonna 19 6]

Got out of work later than I thought so didnt get as much dont as I hoped, but was able to 3M 4000UV the vent, deck fill and fishbox drain thru hull in tonight.

I have each of them tighten down just to snug, so as to not squeeze out all the caulk.   Its takes 24 to surface cure to 3/8 inch, so tomorrow morn I will snug them up.

Deckfill taped up and ready to go



Vent in and caulked.  I am going to run the hose up first before running to the tank.  Seems a good way to keep splash from getting in tank.


Heres the thru hull






i also brought the tank in the boat to measure and pre-fit the lines.   Getting Excited

Today was a productive day.

i started by tightening down the previously 4000 uv'd  fittings and attached the hoses, double clamped.

I also crimped, shrink wrapped, and connected he ground for the deckfill



I did the same for the vent and the thruhull.

Having attached one side of the hoses, I cut the other ends to length.

I pulled out the tank and put down the 5200 for the tank strips


I dropped the tank in and connected the fill, vent, and ground to the tank


I connected the pick-up hose

I added some closed cell foam around the lines under the deck to give them some stability.  Not alot, just in a few spots.


Then i went to the movies with my wife.

When i got home I checked the foam, which had expanded nicely and i pulled off the vent hose to make sure the foam hadnt collapsed it..whjich it hadnt.  That was good news.  

So next i got the coffin lid on the table, busted out the UV silicone and bedded both access hatches.  I also drilled out some form fitting holes for the fuel pick-up line and the sending/ground wiring.



Off to bed and at 10:00 tomorrow, back at it.

Night

When I got home (10:00 pm) I went back out and

[imonna 19 6]

Got home today and dropped the console so i cut mark and pre-drill the holes in the mahogany base to match the console.  drilled them then installed them some silicone marine caulk.  

I then ran two beads of silicone, one arouund the mahogany/deck and one around the mahogany/console.  




She loks like a boat again and looks better than before.

I went from an old half rotted wooden frame that was held to the deck by 4 screws and a console attached the the wood frame with 14 screws; to a varnished mahogany frame held down by 13 1 inch SS screws, a console, held to that by 18 screws and the whole thing sealed with silicone.

and underneath is a 43 gallon tank, How cool is that   .



Almost done.  A few more days and she comes out of the garage for a cleaning and a waxing.

[RickK]

Nice job  

[Capt. Bob]

Lookin' good Bill.  
 
I was never good at the "aesthetics" of caulking though I'm fair at the functional end.
I guess it's all in the wrist.

good work
