Is there anything that keeps molten lead from sticking to metal?

Need to pour lead into a pendulum bob that has a dummy pendulum rod going
through it. I'd like to be able to remove the rod after the lead hardens.
Is there some sort of release compound I can use?
Thanks

Use an oiled aluminum dummy pendulum rod. The molten lead won't stick to
it. And if you heat the rod well before the pour it will come out easier.

You might try a number of things, but lead doesn't usually stick to
aluminum, the oxide coating prevents it. I'd do a trial first with
something like a tin can for a container that you could sacrifice
easily if things became stuck. I've used soapstone to keep solder from
spreading but try bare nekkid aluminum first, might be all you need.

If he can get plain old lead to stick to plain
old aluminum, I believe he could be a millionare. (:

Pffbbt, just get some plain old sodium fluoride. <g>

*Googles*

Hmm, actually that stuff melts pretty hot. Then unless it has a real low
melting eutectic with aluminum oxide, what DO they use...? Hmm, looks like
bromides might have low enough melting points to work...

When I was melting down bullet heads - 45 ACP IIRC - U.S. Army Rifle and Pistol range -
I Smoked the forms with a waxy smoke - think of the oily candles 5 or so in a box
that are used to heat food and such....

A long wick is smoky and I think the smoke (carbon black ) does the trick.

I have successfully used a light dusting of flour for large scuba weights and fishing jigs. I don't use it for bullets or anything with precision tolerances though

Graphite spray if you just need a mold release, but typically lead
doesn't stick to most common mold alloys anyway. Tin, pewter, and some
other common casting alloys can stick.

Flour is a new one for me, but it could work as well as talcum powder.
The advantage these are used for is not as a mold release, but because
the fine particles break up the surface tension of the molten metal and
allow it to flow out better. Talcum powder often works so well that a
mold that was experience incomplete pours starts to flash a little if
the tolerances aren't good. I guess flower shouldn't a surprise. I
have had one customer tell me they use corn starch for the same purpose.

Now, if you mean for soldering applications, I think I would mask, spray
with graphite, and then remove masking before carefully applying flux,
but that's a little beyond my skill/knowledge set.

Yes, I am aware this is a twenty year old ZOMBIE THREAD.

I use correction fluid to prevent the flow of silver solder into areas
where I don't want it - ie the threaded ring of a female hose
connection - just paint it on and work it into joint.

A company I worked at discovered that silicone from candy bar wrappers keeps
solder from sticking. It's applied to help them slide out of vending
machines more easily. The problem appeared after vapor degreasers were
banned.

You've got to be kidding! There are plenty of "Bullet Heads" that post here
regularly, though I don't know how easily they will melt and how much
skimming of spooge you might have to do to cast them into something useful.

That is what we called them - the shell casing holds the primer. The powder is placed
within. A bullet (head) is then inserted. A metal jacket - with a lead open rear end.

These were 45's not 0-.50 boat tails.

I was smart enough back then not to melt down full bullets! Had to walk pulling
my wagon about 6 or so miles down hill with a loaded wagon. UP hill was empty.

I lived down in the flood zone - and the range was somewhat up hill of HWY 54.

Chuckle..Id not heard that usage before from somone who does know
something about firearms as you obviously do.

So I was pulling your chain.

Cartridge= complete unit
Round = complete unit

Cartridge Case = Brass unit
Case = brass unit

Bullet = projectile (no matter the style)

This also applies to self consuming cartridges, just leave out the
word brass and subsitute self consuming.

I think the molds on the A.C. Gilbert lead soldier casting set (the one
with the electricly heated ladle) I had as a kid were aluminum.

Too damn bad the lawyers made them stop selling those, and the chemistry
sets too!

I have no credentials to tell anyone anything on this ng, but intrigued
as I am by your problem (I cast lead bullets), what about making a mold
for the bob, then inserting it. The mold should be relatively easy to
fabricate. I assume you want the lead just for weight.

Those sound like what I had - I think maybe aluminum or white metal of sorts.
Still have some of the small ingots I made. It was dirty work as the
heads were only copper plated. The steel was rusting away.
I saw chem sets last year in a science store. Not near as complete.
