I was watching am epoxying of a parking lot once and the hardener was in a 55ish gallon drum. The epoxy was in the tank on the truck.

All so they could make pretty designs with sand in a parking lot.

Big difference having an extra set of hands mixing the epoxy!!! My buddy Andrew N came over and gave me a hand today. Start to finish took 6 hrs. I was able to spend more time fairing out the tape seams which helped a lot. There's virtually no bubbles in this side.



The differences this time were:
1. Extra hands mixing so I didn't have to sprint up and down the ladder to mix my own
2. Warmer. About 70 degs F which is ideal for this type of work
3. Spent more time on details and was able to bust bubbles as I went
4. Wasn't rushing to get it done before I collapsed



I'll have to check but I think we used the same amount of epoxy. I stuck with the smaller roller this time. It worked fine and allowed me to get those nasty little bubbles as I went. So that's layer 1 on the bottom. I've got 3 more to put on the keel then the 10 oz on the bottom. I'll likely do a little fairing on this layer before I put down the 10 oz. There's also some more carbon fiber to go on the chines.

Shower time!

Last night I looked, in vain, in this thread for your early posts which stated how many layers you would put on the hull bottom. I am likely wrong about this but it seems you had previously stated less layers than that what you propose now.

Even if I am not correct, I am curious if you had 2nd thoughts about the numbers of layers or the type of cloth to use for the hull whether bottom or sides.

Hi Richard

The specs from the designer are for 1 layer of 1708 (45/45) and 1 layer of 1208 (0/90) and one layer of 8 oz plain weave.

I've used 1 layer of 33 oz Quad (45/45/90/90) and will add one layer of 10 oz satin wave after fairing.

Just a little more weight than specified. There's also layers of carbon fiber in strategic places.

12+ hrs of sanding the last two days. Tomorrow I'll finish that up and prepare to hang the glass on the sides and transom. My buddy Peter is coming on Wednesday to help with the glassathon. You might recall Peter launched his Bolger Windemere last year.

[knottybuoyz]

Spent a good chunk of the weekend with the sanders preparing the sides for glass. We'll be hanging and gluing down the glass on the sides and transom tomorrow.

The heavy fabric leaves such a large hard edge they have to be faired to prevent bridging when the next layers are put down.



This fairing will get a quick sanding before the glass goes on. Hopefully it'll prevent a lot of bubbles in the layup.

The old boat shed will be a flurry of activity tomorrow!

[knottybuoyz]

I'd have to say that Peter is a much better conversationalist than the cats who usually hang out with me in the boat shed!



Here's the Lenihan in his native environment. I really think he's missed sanding since completing his own boat. He didn't even bother to change out of his street clothes before he went right to work!

Enamored with my air sander he pointed out all the oversights in my own sanding. Aye, Master I am still but a grasshopper!

I had ordered 25 yds of 1808 biaxial fabric for the sides and transom. Well, as you can likely guess the roll was 1 1/2 yds short so after cutting the two sides off the roll there wasn't enough for the transom. Plan B called for some 22 oz Basalt fabric I had on hand. It looks a lot like carbon fiber but is more like glass. Lighter and stronger and workable just like fiberglass.



Peter was a little unsure of this new material, the dark color doesn't show you when it's wetted out properly. Call in the Peel Ply.



For those of you not familiar with peel ply it's a nylon (or other synthetic fabric) that is laid over top of the fiberglass (Basalt) and squeegeed out. It will reveal areas where more epoxy is required. When cured the fabric is pulled off (peeled) which leaves a sharp textured surface that's ready for painting or whatever without sanding.

So it was a good day in the boat shed. Didn't get all done that I would have liked but it's quality work and there was some good conversation. Doesn't get much better than that!

[knottybuoyz]

The sanding continues along the surfaces where the new cloth will meet the bottom older glass. It's hard getting rid of the shiny stuff, the 33 oz fabric leaves a very course texture.



Got along fine till the monsoons hit. Something caught my eye and it was a paint bucket floating around in circles in a puddle under the boat!

Way too cold and damp for my ole' bones in the shed today. But tinkered with some stuff in the basement. Too pooped to write much so check our our Blog for an update.

M/V She:Kon: Freakin' Brrrrrrrrrr!

That should put you to sleep perdy quick!

[knottybuoyz]

Port side fiberglass hung and ready for epoxy. It's 33' 8" long including 4" overlap on each end.

Looking forward



Looking aft



Looking forward from the transom



Gonna be a sticky ole' time in the boat shed tomorrow!

This mornings task was to build a carrier for my vacuum generator.



This will allow me to fix the small bubbles in the laminate. I'll drill two holes into each bubble and apply vacuum to one and pour some epoxy into the other. The vacuum will pull the epoxy through the bubble filling it up. I'll give it a try this afternoon.

Yesterday I hung the glass on the starboard side.

Bow looking aft.



and aft looking forward.



It's a lot tighter on that side of the shed so it's hard to get a good pic. I wish I had another foot on that side. It'd make life a lot easier.

6 1/2 hours
33' 8" of 1808 biaxial fiberglass
3.5 gallons of epoxy
36' of peel ply

Blood sugar down to 4.1 (skipped lunch)

One very pooped ole' fart!



Still have to standby looking for bubbles etc. especially along the seam near the bottom which I knew was going to be troublesome.

Gotta do it all again tomorrow!
