Lead weights for plants
I have a lead melter/burner device that melts about a US pound of lead at a
time. I'd like to find out how to make a mold to shape it in. My current ideas are, using 1"x1" wood, and fastening it to make a series of steps, X's or triangular shaped ridges /\/\/\/\/\ in some fashion, cap on both ends, and pour the lead into the valleys, and cool, extract, lay on sheet of "_____________" to resist sticking, and heat in oven till a temp that allows the metal to be mallable. Use rolling pin to flatten, and orient them to the same size, cut off the ends, and shape as needed... As you can see, I've got the idea worked out but need the blank filled in.. Also, if you can help make the mold, or improve upon it, I'll make some strips for you too... btw, I've got 40lbs of lead... -- RedForeman ©® future fabricator and creator of a ratbike streetfighter!!! ========================== 2003 TRX450ES 1992 TRX-350 XX (For Sale) '98 Tacoma Ext Cab 4X4 Lifted.... ========================== ø¤°`°¤ø,¸¸¸,ø¤°`°¤ø,¸¸¸,ø¤°`°¤ø,¸¸,ø¤°`°¤ø,¸¸¸,ø¤° `°¤ø,¸¸,ø¤°`°¤ø is that better?? |

I used to do this long long ago for wishing weights - lead strips, just like we use for plants... I used sand, although all I did was pour it flat and cut the strips out using a razor knife and a T-square. hope that inspires something useful. --Tony |

I am just guessing but I would use a cast iron pot to
melt the lead in. And I would try: First!!!!!!! Plaster of Paris. First make a master of what you want in wax. Then make a copy using plaster of Paris. Then pour lead into your plaster mold. Note: If your end product has and odd shape you won't feel bad about breaking the plaster mold away. Although, I have used plastic dividers in the making of the mold and when it dries I remove the plastic dividers and use rubber (inner tube for bike tires, cut in strips) I use plaster of Paris in this manner to make plaster sand castles... Second!!!!!!!! I worked in a foundry,,, making large electrical brass equipment found in high voltage boxes. First we would use a sand that was mixed with (I would guess, oil) until it would clump together when squeezed in your hand under pressure. Not unlike checking the soil in your garden. The sand was put into these buckets and made level with the top edge by dragging a stick across the top. Then you would take your master and press it into the sand mix and remove it, making a mold. And later pouring the lead, or brass. A more complex mold was made by using dividers and straws were added to the master as pouring spouts. If you need more information I would be more than happy to converse with you. If you don't mind my spelling..

That is true, some added information on lead.

If you want thin flat strips then pour the lead onto a marble surface, as
it's cooling run a roller over it, once set then use a guillotine to cut it. Otherwise you use aluminium. Making sinkers for fishing is done with aluminium molds. "RedForeman ©®" wrote in message ...

references? i work in the stained glass industry. it's pretty commonly known
that almost all lead is ingested or inhaled. osha doesn't require gloves when working with lead, although they do require, in certain cases, respirators. in actuality, the only reference to skin in the osha regulation is because of possible skin irritation and not absorption. http://www.osha.gov/pls/oshaweb/owad...RDS&p_id=10030 "Sir Douglas Cook" wrote in message . ..

bubbled forth the following: references? i work in the stained glass industry. it's pretty commonly known that almost all lead is ingested or inhaled. osha doesn't require gloves when working with lead, although they do require, in certain cases, respirators. in actuality, the only reference to skin in the osha regulation is because of possible skin irritation and not absorption. http://www.osha.gov/pls/oshaweb/owad...RDS&p_id=10030 From http://www.osha.gov/SLTC/lead/ "Most exposures occur with inorganic lead. Organic (tetraethyl and tetramethyl) lead, which was added to gasoline up until the late 1970s, is not commonly encountered. Organic forms may be absorbed through the skin, while inorganic forms cannot." However the ERP says recent research indicates that inorganic lead may be absorbed thru the skin. They do not list references though. See this page under Dermal Absorption: http://www.epa.nsw.gov.au/leadsafe/leadinf3.htm Further, this article from the "Journal of the Australasian College of Nutritional & Environmental Medicine, Vol. 15, No. 2, December 1996, pages 11-12." shows that inorganic lead can be absorbed through the skin, and even worse, lead absorbed this way may not show up in the blood: "By applying solutions of the stable lead isotope Pb-204 to the skin of volunteers and measuring the increase in Pb-204 in blood, we were able to show that skin-absorbed lead has a very short residence time in blood3. The ability of lead salts to enter the body through the skin without significantly raising blood lead has important implications for occupational health control, because measurement of lead in blood is the prime technique for monitoring lead exposure. Surveys of workers in lead industries such as lead battery manufacture showed that many of them had very high levels of lead in sweat, even those who had retired or who had been away on leave for several weeks1. Workers in lead industries often wear masks to avoid inhalation of lead, but rarely have skin protection. Some lead battery workers have their skin covered with a layer of finely powdered lead/metal oxide1. Both lead metal and lead oxide were found to dissolve in sweat and pass through the skin1-3." The full article is he http://www.acnem.org/journal/15-2_de...on_of_lead.htm I always thought the main danger from handling lead is that particles that adhere to the skin may be ingested or inhaled by touching the mouth or nose, or via transfer to a cigarette, then inhaled. Looks like we may have to re-think that. HTH Jerry |

I think he has a supply of lead-tin alloy and an interest in utilizing
it. If all he really needed was lead weight for plants, I'd send him some. I buy it in 10 lb spools and give it away at work.
