Bob,

Tuf-Gel would certainly help... did you lap the wheels to the shafts when initially installed? If not, do so this time.

CaptPatrick

Mark, Virtually any grainy substance will be water proof when thoroughly mixed with epoxy, even saw dust... One of my favorite materials is vermiculite, available from garden centers & sold as a soil amendment. Thicken your epoxy first with Cabosil to the consistency of mayonnaise and then add your ...

Bill,

Interlux 2000e would be my choice...

CaptPatrick

Bill,

Epoxy barrier coat is a necessary item to keep water being absorbed into the fiberglass. Lack of a good barrier coat is just asking for osmotic blisters...

CaptPatrick

Bill,

You should be adding a couple or more coats of epoxy barrier coat, and if so, you can skip the gelcoat, and add a little extra barrier coat on that spot...

CaptPatrick

On cored items such as decks, the best strength comes from more glass applied to the under (or tension) side. See: Tips Section.

Remember that plywood will eventually go bad once water gets to it, Coosa is pretty much forever... And lighter.

CaptPatrick

OK, now with the added picture, it looks as though your deck is already removable as a one piece construction.

The size of the Coosa pieces are fine. Bedding them in with thickened resin & without capturing air pockets will be trickier with the larger pieces...

CaptPatrick

Kevin, Again, welcome aboard! It may seem as, by choice of non-rotting materials, you can create a deck that will never have to be removed once installed. Good theory, but not always the case... Remember that are several serviceable items below the deck; exhaust tubing, clamps, mufflers, fuel tank, ...

1/4" is 6.35mm

The 24" cutter have a jaw opening of 5/16" (~8 mm)

CaptPatrick

The little one, however, that the Capt. is proposing, is a good idea for those stubborn rotten bolts that simple cutters or pliers are ineffective with (ineffective in that you end up with the bolt intact and your palm bruised by the effort). Yannis, Notice the jaw capacity and order 1 size greater...

TEKTON makes multiple size bolt cutter from 8" to 36"...

CaptPatrick

Bob,

I presume you'll also be carrying a large cal side arm. The long gun is fine for that 50 yard and over shot, but up close and personal, I'd want some backup in the range of .357 mag - .44 mag.

Have fun & be safe!

If anyone knows any info about the location of the Merritt pic...I sure would like to know. In 1968, Roy Merritt took the jig for the 42 and refined the deckhouse to make it more attractive. The result: the first 43-footer, the Caliban, which helped Allen Merritt win seven out of 11 Cat Cay Tuna To...

Russ,

I'd likely shop with CPR Savers and First Aid Supply and get the best kit I could afford... First aid isn't something you want to skimp on.

CaptPatrick

Mike,

Yup, that's all that's needed on small blisters...

CaptPatrick

Mike, Awlfair will work and is easy, albeit a bit pricey. Really more of a fairing compound... To fill small blister holes I prefer the 3M Premium Filler , any hole larger than 2" diameter use epoxy and fiberglass http://images.jamestowndistributors.com/woeimages/fairing_filler/250_250/3m-46006.jpg

Be highly leery of any program that is fee. Most freeware or shareware can damage your computer or hijack functions and easily cause more problems than what you thought might get fixed.

Highly recommend a maleware program called Malewarebytes that will all but eliminate this type of problem...

That's a lot of twist... 3/8" is going to be heavy. Call me...

CaptPatrick

Dug,

Tempered glass is more flexible and you can overcome some twist with the thickness of the Sikaflex glazing. What are you calling a "mild twist"?

CaptPatrick

Big question for all today is tempered glass or laminated for the side windows. Seems to be strong and valid opinions on both sides of the debate. Tempered glass is 5 - 6 times the strength of ordinary glass. Tempered glass cannot be cut after it has been tempered. Laminated glass is very difficult...

CaptPatrick

Yes. The original struts are bored to 1 7/8" for a standard 1 3/8" bearing. You'll need to have them over-bored to 2" for 1 1/2" thin wall bearing by a qualified under water gear machinist and him install the bearings. If installing Duramax™ the I.D. is 1 1/2" and the O.D. 2" & the Buck Algonquin de...

But you know, until you are married, you just don't realize how easy it is to get in trouble, even when you try and do something nice.

Took three times around to learn that the hard way... Ain't been in that sorta' trouble since!

Mark, Getting wet glass to behave upside down is a real trick... It would be best to carefully fit the Coosa Board as precisely as possible before epoxying into place and glassing it over while you can lay it up on a table upside down. After the underside sets up, then mud it into place with the epo...

Mark, Sorry, but I'm not familiar enough with the construction of the 35 or other Napier designs to be of much use to you... However, as a general rule, wet balsa core is a major problem that never has an inexpensive or easy solution. Once balsa core is wet there's no way to fix the problem other th...

Bolting is pretty much the only solution for HDPE, (Starboard)... But other materials would be better done with epoxy and tabbing. Be sure that any bulkhead that runs up to the hull is tabbed both sides and has a 1/4" of space between the bulkhead edge and the hull. Without that space, you'll have a...

Almost, if not, all were Uniflits Charlie... In 1965, the Navy awarded Uniflite with a contract to build 120 - 31' River Patrol Boats (PBR's).
