Thread: another Yellowtail begins

gee willikers

it's even starting to look like a boat now, i have been able to do much this week have only managed four hours, but this was enough time to get the middle section of the keel cut and all parts glued to the hull, and a bit of filleting with the left over epoxy

all i need to do now is plane the keel so it runs in a nice pleasing line, i really must get some power to my work area all this cutting and planing of the oak keel is killing me

noooooooooooooooooooooo you can give up on her your nearly there

as for the centre board could you not just make it out of 12mm ply and insert a slab of lead low down then epoxy glass over it? that way it will be easy to shape it.

well she's nearly ready to have the hull coated in epoxy, i've spent the last two weeks filleting and sanding (by hand) filling any thing that needed filling sanding and yet more sanding (i'll be glad when this bit is over, and can't wiat to do the same to the interia)

that's all for now my fingers are worn down to the bone

Don't forget, epoxy isn't UV resistant so you'll have to paint her as well. Don't do anything like your final coat though because believe me, it'll get knocked around and you'll have to put another coat on top anyway.

Looking good.

my plan is to use three coats of epoxy wet on wet, then a coat of primer, fill any thing that needs it then another primer coat (if any filling was required) also whilst upside down as she will spend six months a year in the water i'm going to mark the water line (600mm from the strong back all around) and apply one coat of anti fouling. Flip her over fit her out then do the final painting.

She's actually so easy to turn, you could consider leaving her as is, turning her, fitting her out and then turning her to paint her bottom, then upright again for interior paint.

Glen and I turned Sixpence between us - it was so easy we looked at each other in amazement, and she'd have to be heavier than yours. After the damage I've done to my paintwork I'm reluctant to paint anything before I have to now. A siimple but un-noticed epoxy run/drip from fitting a rubbing strip could easily see you damage the paint right down to the primer trying to get it off (don't ask how I &^%$# know )

well managed to get three coats of poxy (wet on wet) on the yellowtail today, she will be left now for around a month before i get around to rubbing her down ready to be primed. i am only leaving it this long as i will be away for a fishing festival.

How long should the epoxy be left to fully cure before priming ?

you may have also noticed that i have only epoxied down/up to and over the rubbing strake which is glued to the shear strake.

i have done it like this after seeing Daddles little mishap with his rubbing strake which was glued over the epoxied hull and unfortunatly one had let go at the stern.
i also had the same thing happen to me when building my first boat. (probably my fault not mixing the poxy correctly or not cleaning and roughning up the hull enough to make a good bond) but it happened so i'm weary of this happening again.
so now when the boat is upright and i have fitted the gunwals to the bare ply i can complete the epoxying useing the lower rubbing strake as the overlap for the epoxy.

Whilst waiting for the epoxy to cure i started to fit some of the internal structure,
My thinking behind doing this is whilst the hull is till upside down and on it's frames i know all the bulkheads for the seating is 407mm up from the bottom of the formers she is sitting on, so this way every bulkhead will be in the exactly the right position, and level. Plus when it comes to turning her over she will be more rigid with all the structure in place.

am i right or wrong to do this?

You won't have to worry about her being too flexible when you lift her off the frames - I doubt you'll notice a thing actually.

Interesting putting the insides in before turning her. Must be fun working under there.

At TAFE, we assembled the interior framing outside of the boat and then just dropped it in as a unit. I certainly worked well enough though I was never too sure how much of this was 'the best way to do it' and how much was 'let's teach them something' and how much was efficient use of bodies. Because there were about ten bods working on each of the two boats, and not everyone was working on planking at any one time, we had the interior framing in the day after she was popped off the strong back.

i finally got back to my yellowtail after leaving her for nearly a month, only to spend another 7 hours giving her the final rub down with 280 wet-dry paper ready for her fist coat of epoxy primmer next weekend.

unfortunately this time of year (xmas) it gets busy at work so plenty of overtime and only weekends to work on her so progress is going to slow for a bit but i guess this will be good as it will give the primmer time to cure fully for the turn over

Richard

Wooo Hooo

last weekend i got the second coat of epoxy primmer on and fitted the rubbing strips to the keel

today with a bit of help from my sister and her husband we managed to turn her over

i was surprised at how solid she felt when turning her over, and i am very pleased to see her the right way up and ready to be fitted out with the internal structure (seating). now it actually looks like all the hard work is turning into somthing that resembles a boat

Richard

-it's great to get to this stage of the build.I have a fun day ahead with the sander on my Yellowtail- the deck,gunwhales and coaming are all getting the treatment before final filling in readiness for the epoxy sealing-although I'm considering using Deks on the gunwhales for ease of maintenance.The rest will be painted,I had extensive brightwork on a previous boat and the Aussie UV had a ball with it ,especially on the horizontal surfaces.Only gunwhales,seat trims,centreboard cover and transom this time.
Cheers,
Dave.

Nice shed HKP!

Hi Dave Thanks

it's great to see her the right way up for a change

had another great day working on her, just gave the inside of the hull a quick sand over to remove some of the larger runs of epoxy, also managed to fit the breast hook, bulkhead no's 1 and attach the Sampson post to it, just to finish of a bit of left over epoxy did a bit of filleting too
so all in all a good productive day for me

She's looking good mate. Exciting times.

There's a rumour that I've got something similar in the shed. I might check that out one day.
