Mylo,
Very interesting question WRT the magnets.

You are a little off on the first point though. I try really hard to mess it up more than once so I can "increase the learning".

Ron,
Now thats a good point. When smoke starts to rise from the wood under the aluminum I am pouring water onto the wood and it does not touch the molten lead.

What does the waterglass do? Prevent air from reaching the wood so it cannot combust?

In case you are getting a little cautious of all this lead smelting!

Don't forget lead shot. Obtainable at fishing shops, gun shops ( not many of these in the UK - but that's where I got mine!)

You can put it in a plastic bag where it will nestle into tight spaces or you can mix it with resin and cast it into shapes.

Quite handy.

This seems like a very good point to me David.
I use fine lead shot (~2 mm diameter) held with epoxy for static modeling, it is unbeatable for ease of use and goes into small nooks and crannies. Typical application is weight in the noses of aircraft (or if these are glass, other parts in the forward area, often difficult to reach) to prevent them from tail-sitting.

Ballast

Mylo - Just somthing to think about. Keep in mind at some point in time your going to have to move this in and out of the water, truck or some other means of transport. You may find that building a tank that would fill with water by means of a pump, just under your WTC or else where, Might be away to have the necssary weight of a keel while at the same time making it easier to remove the water prior to lifting the boat, out of the water... Either that or maybe some weights that are removable. prior to trying to lifting your boat. Bud Lederer did this on his 10 ft Gato Sub. In my own expirence, I failed to consider this when I was building my 1/32 scale Type 21, Now I find that of all my boats it's the one I run the least. just because it's so dam heavy to move around. Your boat is starting out large but you can make it not quite so heavy as it may need to be to run well. Just Something to keep in mind. Your boat is just to nice to be sitting around, I can't wait to see it on the water. My Very Best Wishes.... Mike Dory

Mike,

Believe me, I do

Mike,

Believe me, I do take into account what my boat is going to weigh and what that means in terms of launching / retrieving it. Haven't worked out all the design yet, but I'll be making some sort of "launch dolly" for it to minimize the lower back work. The thing is going to weigh about 40lbs. Regardless, it'll be the sub I play with most since.....it'll be my only sub.
