The PwdRacing HEAVY Weights made from advanced composites from Tundra(tm) are ready to start rolling down the tracks! The 1" disks are 3/8" high and weigh 2.5 oz . The 1.25" disk is 5/16" high and weighs 3.25 oz. The glue sticks are 1/4" diameter and 4" long and 3 weigh 4.1 oz. These are NON-TOXIC! The nice part is that all of them are "workable" with normal tools! This means that you can sand, drill, carve, and cut the material. They can be cut with a good quality scissors or a Cub Scout pocket knife! This makes the sticks very nice for use in their current form. Drill the holes in the side of the car and slip them in! The sticks do have some air in them that can be removed by melting them. The 1/4" sticks are used either in their current shape, or they can be melted to any shape with a $5 high-temp mini 20W glue gun from Wal-Mart. The introductory prices(through the end of BGN-09) I have come up with based on my material costs: Type | Weight | Intro Price | Sticks(3) | 4 oz | $11.95 | Round 1" | 2.5 oz | $7.50 | Round 1.25" | 3.25 oz | $9.95 | Round 1.25" | 4.0 oz | $12.50 | Round 1.25" | 4.5 oz | $14.50 |
After BGN I will raise the prices to take into account the labor/time to make them. The prices will all be going up roughly $5. A quick page for ordering:

Mr. Slick,
Hows does desity compare to lead or tungsten?
Thanks,
Kevin

Thanks for the question.
PURE Lead has a relative gravity of 11.35 g·cm−3 PURE Tungsten is 19.25 g·cm−3 (not very common since most have some "additives")
The specific gravity of the sticks is almost the same as lead. The composite used in making the glue sticks is either 10.5 or 12.5, I'll double check and see which it is.
The disks are made with a different composite and process and are coming out at 14.1 g·cm−3
Thinking of how many cars have extra height due to the tungsten, I went to the 1.25" disk that is 1/16" shorter and .25" wider then the "normal" tungsten disc to get the same weight of 3.25 oz.
The nice part is that you can put axle holes right into the composite which allows for placement where desired -- independent of the axles.
I can make disks of different masses if desired.

are you able to heat and reform to the shape that you need. like you were saying you can shave and cut with a boyscout knife. so it is more like lead than tungston. i am definately interested. i have used steel washers and also nuts and bolts for weight along with the other popular precious metals available to us for weight. jamie

Another common set of questions. . .
Question: Can I get this stuff and melt it like lead?
Answer: Sure, but it melts at a MUCH lower temperature. I use the 20Watt High-Temp Mini Glue gun from Wal-Mart.
Question: I'd like to make a 4 oz. odd shaped slug, but I want it all in one piece.
Answer: That is what the sticks are all about! I have even used a wood burning tool to shape the different "globs" that I have made during testing.
Question: If so, which one do I purchase,
Answer: I would suggest getting TWO set fo the sticks. This will give you some extra material since there is some left over in the glue gun for the first use. . . .
Question: how do I purchase it,
Answer: I'll be putting up a page for the orders soon, but in the mean time sending a PM or an e-mail to PwdRacing@yahoo.com works well.
Question: do you take paypal,
Answer: Yes, the same as the on-line registration. . .
Question: and how soon can I get some to try?
Answer: I have the small flat rate boxes ready to be used and I have a nice supply of product!
I plan on shipping via Priority Mail so shipping will be $7.50 per order to cover postage and packaging. . . . tha is unless you are getting more then USPS allows in the small flat rate box. ;-) I believe that they have a 70 pound limit for the 48 contiguous states and a 4 pound limit on international shipping.

quick page for ordering:
www.pwdracing.com/heavyweightsKeep it simple was the rule when I made the page. . . . Pick the items and remember to add one shipping. :-) hopefully photos will be uploaded tomorrow. . . oh, later today.

I'm sure that there is some sort of limit to the number of times though. I've played with the same material for several days. . . . needs some testing. . . . After using the 20Watt High-Temp Glue gun(<$5 at Wal-Mart) to melt it down I used a wood burning tool with a wide flat blade to smooth/carve the material to several shapes. You could just use another heat source if desired. The High-Temp gun is rated at 193 degrees C -- the package says to have adult supervision and lots of other things. PLEASE read the material with the Glue gun - while this melts lots cooler then Pb, it is still hot enough to cause serious burns.

Yes. The answer is either one. . . the current sticks are the non-toxic 10.5 based on my calculations. I'm going to see about getting the 12.5 and see how the sticks come out. www.pwdracing.com/heavyweightsWarren 612-801-7827

The problem(delay) with the 12.5 sticks is that they do not "flow" very well(at all) at pressures used for our applications.
The 12.5 is only an option at the 1" diameter chunks that work with the commercial injection guns and those have to be modified. . .
I'm working with them to see what can be done to improve the viscosity of the 12.5 at the lower temperatures/pressures so it could be used in the mini high-temp glue guns.
So, for the time being, there will not be 12.5 available for the 1/4" sticks.
The 14.1 is also only a limited supply so far -- I have access to the most in the entire world. . . . but they are going to cook up another batch sometime. Did I mention that this is high tech stuff that you won't find anywhere else? ;D

Can you put the 14.5 in a lead melting machine and pour it like lead? Or would the extreme heat cause a problem?

Never been tried. . . I will ask about the temperature range for the polymers involved. The 14.1 material is very "pre-production small batch" when it was made. The initial scale up from the lab bench. I have been granted access to material that is unavailable anywhere else. I form the discs using a temperature that goes from room temp to 220 degrees C, waits for a while, and then slowly cool to back to room temperature. . . all of this at around 8 tons of pressure. It takes just over 30 minutes to produce a single disc. . . hence the price increase after BGN since I will have to start making a living or find a real job. If you want to have me run the experiment I need to know what you are using to melt your lead. . . or I could see if I am allowed to ship some of the composite that is ready for molding.

I would really like to see some 4oz and 4.5oz disks and they could be 1/4" or 5/16" thick.......Even going to a 1.5" diameter would not be too shabby either... Anyone else?
