Default Pouring Lead For Deep Drop Sinkers

I have 50-60 pounds of lead, and make deep drop sinkers...I have used cut off soda cans, with an old key stuck in and that works fine, but I'd like to make a sash weight shaped sinker I can put in a rod holder....Am I an idiot for wondering if PVC pipe would work as a mold? Would the lead melt it?

Probably will catch fire.

Do a small test.......outside with a fire extinguisher nearby...just in case.

Don't forget to video it so we can "Learn" from your testing.

Doing a quick search, I ran across this.
Just a reminder to be safe and have a VERY well ventilated area....like outside.

http://www.anvilfire.com/FAQs/lead_plumbum.php

"I used to make fishing lures (Pro-Line if any of you have used them). When the Lead was at the correct temperature there was no problem as the OSHA approved ventilation was more then adequate.

The guys that did the pouring and molding wanted to get their numbers up. They turned up the heat on the Lead allowing them to pour an extra mold per casting cycle. This caused a heavy gas that OSHA simply called Lead Vapor. This resulted in four of our workers ending up in the hospital being treated for heavy metal poisoning. All but one fully recovered. My friend Alex Mendoza now suffers extreme daily headaches, joint pain, and memory problems. He also has had a major change in his overall demeanor and is now easily irritated at/by people, objects and situations. He is now disabled and has not been able to hold even a part time job to help make ends meet.


This same issue happened to another friend but not as severe. He works on high performance wheels. He was heating a specialy made wheel to change the bead angle when he "suddenly smelt something funny, got dizzy and dropped to the ground." The hospital stated that it was heavy metal poisoning caused by Lead. After hearing this his boss inspected the wheels and found that Lead was used to fill and weight the bead. He had massive headaches for almost six months afterwards.


Please be careful around Lead especially when melting or casting. OSHA approved ventilation is not sufficient if lead vaporizes. This can cause serious and permanent health problems."

Be careful!

1. Melt lead in a well ventilated area and exhaust fumes to the outside. Air movement that is sufficient to carry away the wisp of smoke from an extinguished match is generally considered sufficient ventilation. Lead melts at 621 degrees (F). When lead is molten, it releases minute amounts of vapors at a progressive rate as temperatures are increased. Harmful levels of lead vaporization are believed to occur at elevated temperatures above 1800 degrees (F). Only lower temperatures between 700-800 degrees are normally needed to cast lead hobby parts. Most melting equipment sold to hobbyists will not raise temperatures much above 900 degrees. Minimize vaporization by operating melters at the lowest temperature that gives good results.

Try a couple using the pvc.
Worse case is it will either melt the pvc enough that the lead runs out and/or catch on fire.
Just make sure there is no moisture in the pvc.

You already know that soda cans work.
What if you used those 6 or 8 oz soda cans that are smaller in diameter than the 12oz cans ?


you can use a dense grain hardwood as a mold numerous times.
You can use high temp RTV silicone as a mold numerous times also.

We had some machined out of alum a while back, friend of mine made them for us.

I could probably cut an aluminum pipe in half lengthwise, then hold it together with hose clamps........

How many once weights do you need.

I made a bunch of 40 oz deep drop weights with a bucket of sand, aluminum pipe, old bluefish hooks, and a pair of vice grips.
Cut the pipe, attach vice grips, bury in sand, pour lead and add eye of galvanized Bluefish hook.

Instead of making them find a person who installs replacement windows, ask him to save you the window weights they remove. In my carear as an installer must have junked thousands of those cast iron weights. they weight between 5 to 12 lbs.and they have holes already in them. Don't breathe the lead fumes deadly.
