Thanks Rick Got the drain tubs and knees in and tabbed up this weekend



Started making a couple bulkheads And positioned them. Looking to tab to stringer and knees. Any thoughts ?

10 gallons of 4 pnd foam

Bulkheads look good.  Yeah those tall stringers take a lot of foam.

Added a couple gussets to bin to help support battery storage

Looking to add 1/2 " material to stringer tops and over tank casket lip . The casket will be held up by that and wrap glass over stringer sides into tank casket.  Tank and fuel will be 500 pounds . Is pvc ok or ply be stronger? What would be material of choice?

[RickK]

Looking good.  The 1/2" will get you up flush with the lip around edge? Do plan to support the bottom of the casket? I think that would be wise. Do you have plans for anything that will secure to the stringers, like some kind of table, etc? The tank casket will be attached to the topping on the stringers by glass run from the outboard side of the stringers, up and over the 1/2" stringer topper and then down into the casket? What type of decking are you going to use?  Maybe you'll have scraps to do the top of the stringers?

[Fishhead]

thanks Rick, I need to end up about 3/4” after the wrapping up of glass over the top I may be able to start with 5/8”  Yes your correct a strip running along top of stringer overhanging casket that will screw up to it and wrap like you explained. The bottom of casket never sat on bottom hull was always suspended. I have 3/4” ply for deck. I’m not reusing the old tank deck cover, its getting decked over this time solid with new tank.

Have you guys that have done some rebuilds found stringer tops that are not on the same plane as the deck is?

That’s not unusual.  The stringers were designed level, but there could be a range of heights when they were bonded in with the putty and tabbing compensating for any variation.  This wasn’t an issue, because the liner/deck were suspended from the hull/deck joint with bonding putty taking up any variance in height.

As for suspending the tank, I’d be inclined to use ply, since that’s what you’re using for the deck.  PVC    can get brittle over time.  Whichever way you go, it would be wise to encapsulate the ply in glass.

[Fishhead]

Thanks , yes I stuck ply down. Been spotty getting good temp days to get work done.

Check out the cuddy bulkhead on port stringer. I backfilled the gap between bulkhead and stringer with thickened epoxy and fibers so it’s supported. Today finished wrapping most of the ply. There is some cracking of the lower left  corner of cuddy door frame you can see. I have exact same thing on my 19.6 also same side. Seems like something wrong with cap on that side to not sit the bulkhead on stringer when they dropped it in?

[RickK]

Nice clean work.  What are you using to wrap the plywood? Looks thick.

[Fishhead]

Thanks Rick I used 3 layers of 1708 got a little more floating material in to go but again bumping into rain next week and field work getting in the way.

[RickK]

I figured you'd be working in that big warehouse you built.

I’m outside but under a cover, one thing I’ve never heard anyone say is “ I built to big of shop”
