So I left High Point with the Scott and JP seminar on mind and how I could incorporate that into my current foam core endeavors...

I took a spin off from Scott and the gram scale method he uses and turned that in to a syringe cc method. I aslo liked the idea of a threded rod tie/clamp version with a sleeve that he had going on at his table.

So, here is what I can report on what I have produced to be my best do far.

using a 1 1/4 diameter pvc with a length of 12" I have worked my way up to 33 ml's of each part a & b. I whipped it with a drill wide open using a paint stir attachment for 45 seconds. (it's been said that a good stir is key and today I will agree whole heartedly)

Poured the mold and 25 minutes later - woala! no flakes, no air voids, no nothing. A good, stiff mold. For those of you who are not getting ideal pours - trapping the pressure might be something to experiment with...

buying this stuff from a vendor might certainly be the most economical option.... but for those of you who have made it a quest, I suggest to start experimenting using a syringe. I bought 60 ml syringes for $1.25 each at my local drug store. Surely at some point too much of the a/b mixture will produce a failure. I'll wait to take that science lab outside once the weather warms!!! For now 33ml of each is the ticket.

please remember this is only one guys .02

For you science techies : room temp was 64.9 (f) and humidity was 22%

Hi Terry, I had also tried the large syringe CC method. I found that since I bought a gallon of the foam that the syringes would not go deep enough after a while without having to tip the can. I went and bought some quart plastic bottles with yorker caps and a small plastic funnel. I fill the bottles and use the little mixing cups. I think the yorker caps work pretty well. I use a ounce of each and get a inch and a half by twelve inch core at seventy five degrees. Great to hear your cores turned out well. I think the stirring with a drill made most of the difference for me also. Have a great day, Rich.

I'm working on a mold made of copper 1 1/2 x14" that will have a removable cap. The rod will extend through the cap and the cap will have a 1/4 inch hole on top to release pressure. I'll see how it goes I'm still in the building part of it and have to get my foam. I hope it's not a bomb!
