I was thinking of a similar approach but hadn't thought about putting lead inside
the square tube. How did you do that?

Lead has a very low melting point. I recall as a kid melting some old lead
plumbing fittings on a Coleman stove. But I would try hard to avoid any
fumes.

Hi guys,
I used to make, and sell, lead bullets in days gone by . . .
Lead melts around 700 degrees F. This is easily done on any kitchen stove
using a cast iron pan. I don't think it creates any vapor at temperatures
you can make with normal equipment so the fumes are not a problem.
On the other hand, if you get your lead from the junk yard it is covered
with all sorts of stuff that will create an unpleasant aroma when heated to
700 degrees.
Don't use an aluminum pot for this - it will melt and damage your stove.
Aluminum melts under 1000 degrees F.
For comparison, steel melts around 2000 degrees, and iron around 5000.
I wouldn't worry about melting the aluminum tube when pouring lead into it
since you will do this at close to 700 degrees. If you already have a bolt
or pin going thru the middle of the tube the lead will be held in place when
it hardens.
On my first aileron I only needed 4 of the steel plates to balance the whole
thing. This might be equivalent to a very small amount of lead. The
problem I see with the lead weights is mostly figuring out how much lead to
use before pouring it.
Good luck,
Paul

The thing I do remember about lead is that it not only melts easily, it's easy
to spill. Boy, does it burn when it hits the skin!

do not archive
" The problem I see with the lead weights is mostly figuring out how much
lead to use before pouring it."
Maybe this will help:
Steel weighs .283 Lbs per cubic inch
Brass weighs .307 lbs. per cubic inch
Lead weighs .409 lbs. per cubic inch
Need a trick to remember this?
Note all weights are Chevy engine displacements!

How about buying some lead shot at the gunsmith's and moulding it in epoxy

Tire shops have used wheel weights that can be melted. It isn't pure lead and has
a few % of antimony in it to increase hardness.

I don't think lead and aluminum together directly corrode, but contaminants and
water could get between the lead and bare aluminum and cause a problem.
