Ian.... I've, um, buggered your boat...

[The Bigfella]

Yep.

That's the phone call I got yesterday evening.

Someone, who shall remain nameless, took my boat out of his shed, covered it and left it in the sun yesterday. It was 42C yesterday... 108F.

"The glue in the keel has let go....."

Um, yep - so would you if you climbed under a cover in that sun. I can't blame the epoxy for that.

Barry hasn't bothered to go and look either. I might go over later today....

I was going to glass the keel this coming week.

It looks like this boat will get a third keel before it ever touches the water.

[C. Ross]

Oh bugger. I've been watching your thread avidly. A discouraging setback...

[Tinman]

Is the phone caller still alive??

[The Bigfella]

Is the phone caller still alive??

I decided not to visit for a look for a while......

[Paul Pless]

ouch

[JimD]

I would be quite annoyed. Does the boat have a name?

[The Bigfella]

Jim - we had some discussion about that on another thread. There's two possible names - a decision to be made before launching.

It is a David Payne design, the Yellowtail, and it will spend some time behind my cruiser Grantala. Grantala was in active service during WW2 as HMAS Halcyon and then HMAS Kimra. My daughter thinks Kimra would be appropriate. Tony H thought Shashimi would be appropriate - with a link to Yellowtail Tuna, and Grantala's role chasing Japanese subs...

[JimD]

How about Thrice Keeled Over? :o

[The Bigfella]

Nice one Jim. Nice one.

[The Bigfella]

I've just been over for a quick look. It doesn't seem too bad to me. I'm inclined to spline it. I might just run a router down at about 1/2" depth and see if the cracks in the glue line stop. If not, try again at 1". Then make a decision.

I didn't take a camera over - I didn't want to to pressure him. Sh!t happens, after all.....

[Captain Blight]

Seems to me a long #10 screw through the whole works, every eight inches or so, would be cheap insurance against this sort of thing happening again. That spline idea of yours sounds like a good one, too.

[Tinman]

How about Thrice Keeled Over? :o

So that is what TKO means!!

[The Bigfella]

I've been over again with Barry for a look. Poor old "nameless" still looked worried... "I'll fix it"..... Get stuffed, it isn't a worry, WE will fix it.....

We ran a feeler guage down the cracks - which are in the centreboard cheeks and where we had to laminate a bit on to make the keel wider. They only go down about 3/4" - so we grabbed a couple of 3mm thick Spotted Gum strips I have to do the internals of the boat. We will rout or plunge cut a slot and glue them in... and Bob's yer Uncle.

Bazza was OK, but wanted to say something..... "You do a good job and......." He's got over it fortunately

[Duncan Gibbs]

Glad to hear it all turned out well mate! Only just caught this thread... I've been a busy boy!

So mate will she be sea-bourne by September?

AND.... (now for the sixty four thousand dollar question).... Will you have a working galley and head?? :D;):p

[Wooden Boat Fittings]

That was bad luck, Ian. I'm glad it's fixable okay. Given that we've been having our hottest weather on record the last few days, I suppose some could think it was a good thing it wasn't worse....

(I assume our weather is already being discussed on The Bilge by now? I've just heard that there are 76 confirmed dead and over 700 houses lost in Victoria. So far.)

[The Bigfella]

Yeah Mike, I put a thread up on that, I think in the Bilge - it should have been upstairs I guess.

I haven't been in the slightest worried about the damage to the Yellowtail - it just doesn't rate, does it? I know my friend was really concerned about it, but my attitude is somewhat different to these things.

[Wooden Boat Fittings]

.
Yep, I rather guessed that.

[BarnacleGrim]

Damn, I thought a through-hull had been violated when I first read the title :eek:

[coelacanth2]

How about "Charm", as in "Third time's the charm"? Glad to hear it's reasonably do-able.

[Paul Pless]

I haven't been in the slightest worried about the damage to the Yellowtail - it just doesn't rate, does it? I know my friend was really concerned about it, but my attitude is somewhat different to these things.Pretty good and proper way to approach it I think.


But... Shouldn't this be an addendum to the 'Epoxy is Crap' thread?;)

[Lew Barrett]

Seared Ahi could be a good name for a Yellowtail kept out in the Australian sun.

[Lew Barrett]

Funny! I bet it was a blue tarp and not a white one. Epoxy and blue tarps are crap:D

[The Bigfella]

Seared Ahi could be a good name for a Yellowtail kept out in the Australian sun.

Nice one Lew - but I really like Tony's suggestion.... Shashimi.

btw - I'm not blaming this one on epoxy. It was 42C, direct sun, under a blue tarp. Yes, the epoxy let go on the centreboard doublers and the cheek pieces on the shoe - to a depth of 3/4". It must have been at least 90C under that tarp.... There's not the slightest bit of damage to the rest of the boat that was under the tarp - the fibreglassed hull - which is also epoxy.

[Lew Barrett]

All the really original thought was Terry's in the first place. Sashimi is clearly more appropriate!

[py]

I'd have thought epoxy should hold up in 40 odd degrees, even 90. Aren't there lots of threads on here about people boiling their glue samples for a week to test them? Surely masts and decks and deck fittings and topsides and all sorts of bits of boats left on a trailer or in the water in the sun get up to those temps here in oz on a regular basis? I just wonder if there was problem with your gluing was and its just lucky it popped off before you covered it up with something?? Or was the keel timber still green? Nothing going to hold that still as it dries out.

[The Bigfella]

py - I just had a quick look to see what temps the epoxy is supposed to take.

Barry used some Botecote that I supplied - with the UV resistant hardener. The filler was West microfibre. The timber that let go was kiln-dried Spotted Gum. Interesting to see that the gap has closed slightly today (it was only 1mm or less - just enough to slide a thin feeler gauge in to check how far down we need to go. It is raining today, so the humidity must be enough to close it up a bit.

There's a reference on the Boatcraft Pacific site to a "Heat Distortion Temperature" of 50C. I don't know what temp it got to under the blue tarp - but it would have been over 50C. The ambient temp was 42C. Car safety lectures talk about temps inside cars in summer getting over 140C.

I've got a digital thermometer or two floating around. I might do some comparative tests between the Botecote and the West. I've used a fair bit of both. I'm particularly interested given I need to do more teak on Grantala soon and I'd like to use the more heat resistant glue.

The Botecote reference is at the bottom of this page....

Speaking of "how far down we need to go" I will be splining it with some of the Spotted Gum that is 3.7mm thick, probably by just running a circular saw along the glue joint to a depth of about 25mm - the gap only going in about 20mm. I could go deeper - the Spottie is about 42mm wide.
