Hi there Dan, it'll be interesting to see which way you go regarding the hull coatings inside and out. Hope it all goes well for you, whichever way you choose - following along...  :-))

Thank you Dave, glad you think so!


And thank you too Ray! I'll obviously posting updates when the time comes.


Should anyone be interested here's a timelapse video Ive done. It's not the best, it took me practically until the end to find the right camera settings. It didn't like my garage lighting

Hi Dan


Last but not least, everyone will give you information on what to do and how to do it - and that my friend is one of the worst things of a forum - because, you will have so much information - you don't know what to do for the best.


As an old guy once said to me years ago, when the West system first came into the UK and we were on about trying to spray the West system through spray guns and we were on about thinning the stuff down and the rep said if it was meant to be thinner they would make it thinner - so, if you work with what you have you will master it.    So, my advice to you is, if you are not 100% happy with Zpoxy don't try and thin it down - because all sorts of things can go wrong - even with the best advice.


There is a link here to when I built my tug and I used resin which I purchased from Halfords (they sell it for car repairs as you know) and also I also used 2 tins of this stuff to cover the hull of HMS Exeter - which - if you are interested my build is on this Forum.   (The WW2 Exeter)

Thanks John! I always find it interesting to hear the different techniques people will use which ultimately leads to the  same outcome. Gives food for thought.


When I get a few minutes I'll definitely have a read over your thread!


Thanks again!

I enjoyed your build video! I remain impressed with your manipulating those sheets of ply to form the plates and cannot wait to see other parts starting to grow on your workbench.


She looks nice and even with no warping or twisting, Nice.

Glad to hear you liked the video! Very few of the sheets of ply were cut 'square'. Each sheet was cut to match the curvature of the hull frames where it would sit. Once in place it sits over half the frame, allowing the next sheet to butt up to it nice and tightly.  It was then pinned as the glue set.


Attached is a photo of one of the ply sheets cut to match the curvature of the frames on which it sat.

Hi all,  I have a problem. I've fiberglassed the hull with limited success. The hull had a coat of resin and was left to dry for a few days before a quick sanding down, all seemed fine. I then applied a fiberglass cloth with resin, mixed exactly as instructed. After a few days you could tell it had set but it was very slightly tacky. So I did some research and it suggested it might be the mixing ratio was wrong or I hadn't mixed the two for long enough. I was confident it wasn't this, but incase I went and purchased a new digital scales as I read I could simply apply a second coat of resin to rectify the issue. Over a week has past since the second coat has been applied to the cloth and again it's very so slightly tacky to touch. There's no residue on my hands after touching it, but it's clogging my sanding pads pretty quick.
So do I try a 3rd coat, but apply it to the hull in the house where it's warmer than the garage?
The cloth that over hangs the hull that I'll be cutting off has gone off solid. So I'm not sure what the issue is. Has anyone got any advice they could offer please?

Are you using a laminating resin or a surfacing resin?

Have you tried washing the hull? Many epoxies produce amine blush - a waxy coating on the surface - especially in cool or damp conditions.  This coating feels sticky to the touch even though the resin has fully cured.  The amine blush washes off with soap and water.  Try that, and see if things get better.  (Strictly speaking, you should wash this off before applying another coat, although in my limited experience it is not fatal if you fail to do this.)

Hope that helps.

Greg

Hi Greg, thanks for the info, I wasn't aware of that. I have given it a wash down and it does feel slightly better, but I think I'm going to try sanding it down and applying one more coat and see where that leaves me.


Cheers,


Dan

AN hi again Dan loved lookin at your ocean hull but this is just my opinion but if i was you id fit a bow thruster in her even if the real ship hasnt got one as you can do it now easy but onece built it wont be as remember  thats a big hull an will be high out of the water an the wind blowin the hull about will play havoc with how you want her to stay in the water as thats the reason i fitted one in my tiger but up to you on that

Hi Chris,


Glad you liked the video and how the hulls looking. If I could work that fast I'd have completed it by now  {-)
The drawings show a bow thruster so I do plan on installing one. This will be installed next when I do the running gear which I have recently ordered.




Hi Bob,


Thanks for sharing these photos! Woods hard enough to work with, I can't imagine the headaches of working with metal! I didn't realise that museum existed, it's not to far from me so can definitely see a visit in the not to distant future!


Cheers,


Dan

its well worth a visit, I was blown away by it, they have virtually no restriction on aircraft access, so you can touch and walk around and under, amazing and friendly staff.

Hi Chris,
I'm still filling and sanding but I don't think I'm too far away from finishing it. I now have my props and shafts to fit so I'm keen to get the hull don't so I can get these in!

Dan,



I know itís a pain when the resining does not do what you need, but just take your time with the filling an sanding it will be worth it in the end  :-))

Progress has finally been made after hours and hours of mind numbing sanding. It's now somewhat close to where I want it.


Next will be cutting out any openings needed, fitting the prop shafts and rudders and fitting the main deck.

Hi Chris, thanks very much! There's a few bits that didn't turn out exactly how I was hoping but im still happy regardless. I'll find a way. I will more than likely carry it into the water with my waders on. However that's a long way off so have plenty of time to find a way  :-))
Your only as young as you feel but the 15 years have gone quick and alot has changed. We welcomed our second child late last week so progress will be slow for a few months I expect. But I'm in no rush  :-))
