Great to hear of progress Harry, that was pretty fast! 
How much trouble is it to adjust the size of the castings.
I am looking forward to getting my hangar queens on the high rail. Great work Harry!
I take it you tried the non-shrinking mold material? You still get a half percent shrink,but that is way better than 4 1/2%.
Great news, we may all be back in business again.
Any news on this project?
Patience Grasshopper, Harry's working on it.
Looking forward to a solution. Mine frames shattered as I worked to reinforce them with epoxy.
I will not be working on the repro truck frames now until after the holidays. One of my sons has a medical issue that has slowed me down, and we just lost our zinc caster for the wheels. My injection molder has also moved. The GG-1 part is taking a back seat for now. Sorry. Harry 
Sorry to hear that Harry. Best to your family and especially your son for improved health. After reading this thread I really need to get my JLC GG1 out of the box as it's been boxed for the last 3 years.
We of course patiently await your return to this project. No hurry on our part.
Prayers sent for your son, Harry...
Harry III is doing much better, he still has one thing they have to "fix" early next year. He got very lucky, it didn't sound good when I first heard about his issue!
Any progress on getting these replacements made? Thanks in advance for any replies!
It's still being worked, the second set of castings were close, but not perfect. As Harry stated, lots of things have conspired to slow down progress. The project hasn't been abandoned, we're still hoping to see a finished frame sometime soon.

Soon?
Well, "soon" is a flexible term. 
The GG-1 truck frames:
We have re-visited the truck frame production logistics. 1st. I do have a set cast in plastic , in a resin mold by my 'science' worker. We have trimmed out and mounted on a GG-1 and lo & behold it appears to be working smoothly. The trucks are mounted , but have NOT pulled a string of cars yet. I expect to put thru that job this weekend. My problem is, and I want your in-put on this, good or bad!! Would you guys accept a plastic type frame? What would be $ practical. I already have over $1K into this w/ the original Pewter castings & mold. Now we have another new mold, vacumn chamber, pump etc. tied up into the plastic production. I am thinking realistically about $100.00 a pair. 
My 'science' employee works part time, 1 day a week, & we are able to pour and trim only one pr. in the course of a day. That is only 4 pair a month. 
Your thoughts please. Harry
I wouldn't mind plastic. Cast metal for a $100 is a great price or is this the plastic cost?
This is a 'state of the art ' plastic, very tough type. Harry
I'd be willing to pay as much as $200 for replacement frames.
Harry the price for plastic would be about $100?
