Hi John thanks for the comments.  I had completely overlooked the thought of being able to see the water pressure gauge.  I can see it clearly without the superstructure being on but its something I will need to think about so thanks for that  :-))   Fortunately though the gas tank is removable and thats what I intend to do when it requires filling and also I can get quite a lot of ballast actually underneath the boiler/motor plate.  If I cant get enough there I'll probably fix it outside in the keel but here's hoping

Hi Mark.
Lead shot from a gunshop is incredibly heavy if expensive but can poor into shapes and add resin to bind it. Using with clingfilm or similar to prevent it sticking to the hull. If it then turns out to be over weight you can pull it out and cut some off. Alternatively just us individual bags and it still fits better than blocks of lead

Hi Andy  - yep this is what I used on my last build and it worked great.  I like the way it moulds to the hull and doesn't move when underway  :-))

I wouldn’t worry about removing the gas tank each time to fill it. I don’t.  If there’s a bit of gas lying around it just goes pop when you light the burner. You’ll have the tophamper off for filling anyway, keeps your eyebrows short!

One needs a good sturdy bag for the lead shot nothing worse than the little black buggers rolling around in the hull and difficult to remove,
Cheers

Hi John on my last build I found the places that I wanted to place the lead shot and then placed cling film into that area.  I then poured the lead shot onto the cling film and pulled it around to make a bag.  Next I poured epoxy resin into the bag of shot and then pushed the bag exactly into place.  Once the epoxy had hardened the shot was like a solid block and was going no where.  It was like a solid piece of lead that fitted exactly into the hull but was also removable because the cling film stopped it from sticking to the hull.  It is possible to remove the cling film but I've just left mine on.

Bonjour,
In France, we can find 2mm thick sheets of lead. I cut it with scissors to put in in the frame without any glue because, I have to finish the boat and remove some weight, nothing moves : https://www.youtube.com/watch?v=Y6q4yYpVcA8

I use lead sheet for ballast too, it is very good as it is easy to cut and  fit on the bottom of the hull even under the steam plant and other tight spots.

Sorry about the lack of updates on this build but I've had a bit of a set back.


I was using some 20 minute epoxy resin on the inside to fill up some of the weaker parts of the hull.  I did this on my last build and it worked well.  Unfortunately I poured a bit to much in one area and wow - the heat build up was so hot that I couldn't even touch the hull with my bare fingers.  I cooled it all down using wet cloths on the outside for about 30 minutes which worked well.


The good news was that the wood work did not move one bit under such heat so the planking has proven to be solid.  The bad news was that it blistered the epoxy finish on the outside of the hull in a few small places.  It really did look bad but after a few days of sanding back and repair work its all looking good again.


Such a silly mistake by me that has caused days of work.  Anyway I'm now back to where I was weeks ago so hopefully I'll have something more positive soon

That was a swift rescue with the wet cloths Mark, you definitely avoided a total disaster there.


Hopefully, that will be your last setback on this build  :-)

Very lucky Mark its called exotherm we used to have lots of problems in telephone cable joints as it would melt the tiny plastic insulation.
 I updated my Joffre build post but so far no replies oh well tugs and towing.

Lads I was lucky - if this had been a plastic or resin hull it would have definitely ruined the complete thing.  I knew that epoxy could get warm but I never realised it could get as hot as it did.  I think its important to put our errors on our build logs so that others can see that nothing quite goes to plan  {-)


I can now get on with getting the inside of the hull coated as I've finished sanding it out which quite frankly is a thankless task.  Oh and I need to get the prop tube glued in too.
