Looking at the illustration in post #37, I can see that the sprue puddle of each individual cavity is perhaps too small to remain fluid long enough to feed molten alloy into the cavity as the alloy...

This is probably the sticky that is being suggested.

I process a fair amount of range brass with a range of dirt and oxide formation. I use both corn cob and walnut media. I notice the dull look when the media needs to be changed due to build up of...

Hmm, most of the references I see say that lead melts at 621 F. Typo?

It was mentioned that the "linotype" the OP had was in letter form so it is not lino but perhaps monotype. When you are spinning your wheels testing unknown blends and alloys, you would do well to...

Are you using the powder measure mounted in a stand, or moving it from case to case by hand. Free handing will often result in some jostling and that will shift the powder around and can result in...

The most common way to deal with zinc contaminated alloy is to let it stand quietly while at casting temp and skim the dross about every 15 minutes until most of the dross is minimal. Then cast into...

Walnut hull will Scrub where the cob might be too soft.

When I use the dry media in the vibrating tumbler, I dampen several small cloth patches with mineral spirits and toss them in with the brass. The spirits seems to help attract the black debris. ...

Maybe this will help establish your value?

Lee has two different types of two cavity molds and have different alignment systems for the mold halves. Also the alignment areas require a little lube from time to time. Clean the molds if they...

Just skim and scoop off the dry material as you would with the dross left after fluxing. I use a cheap spoon with a small hole drilled in the bowl to allow the hot lead to drain out while retaining...

This is a heads up that at times some organ pipes contain metals such as zinc. You may want to do the acid test on the pipes before tossing them in the...

Please do NOT use a wood dowel to drive a slug through the rifle barrel. If it breaks or gets jammed you will visit a gun smith to have it removed. The bore diameter is the minor measurement of the...

Very interesting evaluation of the barrel. Too bad the really rough area is at the breech and not the muzzle. A shorter barrel would not be that big a problem. It will be interesting to see if ...

This is the link you are looking for to determine if you have an isotope container or not. And it is not one of these.

I guess we should agree to disagree. I have never found any written reference to support the theory that one can increase the lead alloy hardness by repeated heat and quench, UNLESS you change the...

I have been fortunate through the years to get an extra pot for the various alloys. If you do decide to drain a bottom pour pot, do not drain it empty as that will result in dross being drawn into...

I understand the quenching from the mold or oven heat treating and quenching. But the double chilling is the question. Once you heat the item up again, you destroy the original HT/Q and end up...

Perhaps some do not understand that once the thread is started, it goes where it goes as long as there is some benefit to the forum in general. Participation is encouraged.

Perhaps he is thinking that lead does work harden, but then returns to the normal condition after a time has passed. Dead soft lead by hardness testing, or by source that might have some antimony in...

Thank you for looking, please close thread.

Price it out and offer it in the S&S. There is usually a market for clean bees wax.

There is not a thing wrong with melting them down into something you can use. But if you do not need the alloy, you might prepare a dust free container and put them on a shelf. You have a thousand...
