As I have said Dave T has warned against low temp melt metals before and has cautioned me yet again. Even though I don’t mind experimenting and going against the grain on some things, I also believe it is an easier path to learn from the wisdom of experience instead of making the same mistakes as other to arrive at conclusions they have already made. I have the pewter so I will cast the final trucks in pewter. I will use the low melt to cast my experiments until I get a pattern I like. The regular RTV is way cheaper than the high temp so the two are a good combination until I come up with a final product I like. The beauty of the low temp metal for this is that I don’t waste resin with each attempt or waste expensive high temp mold material . I can simply recycle the unwanted truck frames.
Randy,
I have been and am still very tempted to tackle fully functional trucks. For one they look better in my opinion. I know there is ton of debate out there about the necessity of it, but that aside I think it provides for finer detail. At one point I wanted to make real arch bar trucks from brass bar stock and real bolts ect. This is still in the back of my mind.
However, I don’t believe a fully equalized truck is needed. And for making a bunch of trucks for freight equipment I am content with casting nice looking solid trucks. I believe i can make them better looking than the first attempt. Hollowing out the entire center isn’t possible at this point in the design because of how the bolsters will be attached. Also a key factor in all of this is to make the truck heavy. So I am inclined to add metl not remove it.
Thanks for the input and rest assured a much more detailed truck is still in the works for the tender.
