I can make any weight, I am currently limited to the standard diameters for the presses. 1.25" is as large as they go. I believe that the presses can do larger but I would have to spend some serious dollars for the molds.

Well, I got my 3.25 oz. disc today and my sticks for melting. This stuff looks awesome! I was able to cut into it very easily with a sharp x-acto blade. I won't have time to get it into a car for the WIPR race, but I should be able to build 3 more cars for the BGN using this stuff. So far it looks very promising. ;D I will eat a few ounces of it today for lunch and try out the toxicity of it and hopefully I will get back to you............Boy do I feel sorry for the toilet ;D Warren, get moving on those 4+ ounce discs. I am gonna need some and I'd like to get the Pre-BGN price if I could.

So how is your tummy? The polymer/resin in the composite probably didn't even add any flavor. To get a 4oz I would have to go thicker then the 5/16" for the 3.25oz. For the 1.25" diameter rounds: 3.25oz is the 5/16" (1/3", or .31 inches) $12.50 = 4oz would be about 5/13" inch (3/8", or .38 inches) $14.50 = 4.5oz would be about 29/67" (3/7", or .43 inches) 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:
www.pwdracing.com/heavyweightsYou may notice that the price isn't quite linear per ounce for the larger disks due to "defective disks" when going thicker. . . . more polymer/resin research I suppose. . . . that or better production techniques, maybe 25 tons of pressure . . . the problem with the higher pressures would be finding the presses and also potentially the loss of some workability - I'm thinking it would become brittle and harder. I'm willing to make some of the larger ones if someone wants to buy them. ;D

I'm willing to make what ever has been ordered.
I leave for Boy Scout Summer Camp for a week on Sunday. I then have 36 hours in town before leaving on the Boy Scout High Adventure trip to Philmont on July 6th.
We get back from Philmont and I believe I'll have another 36 hours or so until we head out for the BGN-2009.
Any orders I get before or during BGN I will honor the introductory prices.
I updated the order page to have the 4 and the 4.5 ounce 1.25" diameter discs.

I got my "Heavy Weights" today and they are AWESOME !! I got a couple disks and some of the sticks for melting. I'm not sure how this stuff is made, but it looks and feels like a regular tungsten disk. I'll be making a trip to the store today to pick up a high temp glue gun so I can give the sticks a try. Great job Warren...I am definitely impressed.

Remember to get the 20 watt mini and to let the gun heat fully - at least 10 minutes. . . You are heating a lot of mass to get it to "flow" - some have found that it really needs to be pushed with the thumb rather then using the trigger. In the mean time - I have been experimenting with a new format. The "Adjustment Line" is thin "strings" of the 10.5 composite. It is some interesting stuff. I was asked if it could be used in a normal Pb melting pot. . . I don't have one so I did what seemed reasonable - put 2 oz. in some aluminum foil in a pan on the stove - medium high - 10 minutes - softened it up to where it could be compressed into a single "chunk". The "Adjustment Line" can be broken into small sections for even better weight control. I found that using the micrometer to measure the length desired I could push against the tips to "cut" the proper length.... with 1/4" being 1/100th of an ounce it is quick to fine tune a car. Imagine check-in with a bunch of this at the pre-weigh-in scale. Just set up the pre-weigh-in table with the "Adjustment Line" to add weight and a small drill on a pin vise to remove weight from the pre-installed material. MUCH SAFER and EASIER then ANY of the other alternatives. Here are some weights and lengths: OZ | Inches | 0.01 | 0.25 | 0.02 | 0.5 | 0.05 | 1.25 | 0.1 | 2.5 | 0.3 | 7.5 |
I'm thinking that if I supply the Adjustment Line in random lengths, that it could be made into what ever lengths are wanted. The Adjustment Line will be added to the HEAVY WEIGHT order form. . . . How does $2.95 per ounce sound? ;D There is very little work on my part to reform this into the thin strands for Adjustment Line so there will be no price adjustment after BGN. I'm also working on a method of mass producing the glue sticks so they can stay the same price too! A quick page for ordering:

Starting messing around with the "Heavy Weights" a few night ago. These things are nice !! For all you guys who like using tungsten rounds, the "Heavy Weight" rounds are the way to go. The thing I liked was there is no more having to shorten your axles to be able to move the round back farther. The "Heavy Weights" drill very easy and you can drill an axle hole right onto them. I thought that was neat !!
For you guys who were asking if the "Heavy Weights" sticks can be melted in a lead pot...the answer is no !! They work fine in the glue gun, but didn't fair to well in the melting pot.

Has anyone tried using a soldering gun to melt this stuff to help it flow where you want instead of the glue gun?
The tip should get hot enough to cause the stuff to melt and flow - I think.
Just curious.

I spent a few hours between Philmont and heading out to BGN in the lab talking with the scientists. . . . made some suggestions and observations and ran some experiments. . .
I will be doing a couple of demonstrations at BGN on how to "FORM YOUR OWN" weights! The method so far is achieving densities higher then lead - straight from the kitchen with tools and methods that the kids can be involved with!
I head out in 11 hours so I am going to get some sleep. .

Recieved me weight in the mail. I am looking forward to making new cars with these weights and Lester's bodies. I think they are going to turn out great and I plan on running it at Lima.

finally got around to updating the order page. . . .
added the 1.5" square 4 ounce weight to the items.
now to get the video for Extreme Pro-Mod! that hard drive has to be some where in the van. . .

Warren,
I received my heavy weights earlier this week and found them to be AWESOME!! I am making a brand new bearing car and already have the 4oz weight added. I am using a 1 piece axle in the rear so the axle will go right through the weight. There is no way I could do that with tungsten unless I felt like paying bucks to have it EDM burnt. So thanks for making these available to us.

What are going to be the favorites? Shapes: - Round 1" or 1.25"
- Square 1", 1.25", or 1.5"
And once you select a form factor what weights? - 2.5 ounce
- 3.25 ounce
- 4 ounce
- 4.5 ounce
And the following shapes . . . weight TBD (same density as the others!) - Square Rod 3/8" x 3/8" x 1.5"
- Round Rod 5/16" x 1.5"
or the "Adjustment Line" that can be also "Mold-Your-Own" . . . What mix do I bring to Lima too?

Warren, could you fashion something such as 1/4" thick x 1.5" wide x 1" long (rectangular)? Any idea of how much this would weight? Or a 1/4" thick 1.5" square would be great... excess could easily be trimmed off. I'm not so concerned with latitudinal concentration as I am longitudinal, and ideally I'd like to stick with no more than 1/4" thick since that's the size pine board I use to fashion bodies.
Let me know if you can do something like this. Thanks!
Since this can be drilled into... wow... the possibilities are endless! Holy concentrated COM Batman!
