This could be the end
« on: November 09, 2007, 10:51:09 PM »

Ballast...I never thought i would have such a problem as i have with this...trying to get any lead where i live is virtually impossible..first tried all  of the local builders merchants...any lead they had was padlocked [lock and key].!!!!had a quote for the one decent roll that i thought i would need for 3 boats im building..only 160!!!! it was not much bigger than a can of beans...so off i went to the scrapyard...None .....tirefitters ..again .nothing as they are selling the wheel balance lead weights for the money...could this spell the end of my model boat sailing  :'(

As I mentioned on another thread, thefts of metal - scrap or otherwise - are currently rife in this area. Last week the parish church was hit. They are currently being re-roofed and three rolls of lead were taken off the scaffolding overnight. And no, I didn't get any!

It's the people who steal cast iron manhole covers from the middle of the road leaving a gaping hole which gets me - unbelievable!

If you ever see an old cast Iron radiator (from old schools and hospitals) get a hold of it.
most companies when renovating bin them but the scrap yards give on average 150 for one.

Local gun shop sells shot ......... Very easy to get weight just right as its in small balls, takes up small area again as it small balls, fix with apoxy either mixing in with the shot or just over the top to hold in place.

Tom, it's not the nonavailability of lead thats the problem, it's the current price. If you can still get lead shot at sensible prices, buy it now and stock up. But I thought we were supposed to be saving the planet by killing animals with non-toxic shot?

Get yourself a plastic bag, mix up some cement mix, pour into the bag and put it into the bottom of your boat and mould it to shape, let dry, remove from boat, take off plastic bag, varnish it and stick it back in the boat. Not as dense as lead but it is a way around the lead problem if you have the room to do it.

Use dry clean sand.  Pour it into your boat, distribute it where you want, leaving yourself a degree of a safety margin, and then pour resin over it to seal it in.  The resin will soak through and it will be there for the life of the model.

Lead just happens to be very dense so it doesn't take a lot to give you the weight you require but it is by no means the only medium suitable for ballasting.

Just a thought, but why not use batteries. Even dead ones have weight, and if you use "usable" ones you will have an extended sailing time!

Ideally, the ballast should be denser than water.  lead is ideal, steel nails can be used, as mentioned above with other materials, spread out and resined in.  Water ballasting should only be a trimming device as it will raise the centre of gravity and reduce stability.  On a large model, due attention must be paid to where the CoG ts before you add water, and after.

Have you seen the size and weight of those things, it would cost more than the boat was worth to use those things in a large model.
I think that is trying to exploit those who know no better.

Agreed - though in practical terms, iron/steel (~7500kg/m3) isn't much different to lead (11300kg/m3) and obviously much cheaper. The breadth and inherent stability of the ship I'm working on (a 1/72nd scale Dreadnought) is making me lean towards concrete (~2400 kg/m3) as I want a slow roll and a more realistic metacentric height than those narrower hulled models you see where the ballast is too low and too dense.

  Just bought some half-kilo bars of solder from my plumbing wholesaler. Forget the exact price, but in the order of 6.

There was lead shot on ebay recently - 10kg for 25 if you collected it yourself.  The chap seemed to deal in Subaqua stuff and sold the shot for making weight belts apparently.

I saw reference to the fact that many churches are marking their lead roofing to enable identification when stolen. So, look out you guys!

well I got a roll of lead flashing fro B&Q, however the weights that tyre places use are 60g steel, they are still suitable as lead.
