There's certainly something to be said for a database organized by prototype roadname and number, but I would also like to see a database where I could look up a model (say, the Atlas N-scale offset

If you use Dow Corning J RTV and let it set for 72 hours after curing before cutting it open there is NO shrinkage. Thank you Larry Jackman ljack70117@...

Gene, Yes, there is mold shrinkage in addition to resin shrinkage. Both shrinkages depend on the materials used and the age of the mold. Molds continue to shrink for a while after you've removed

Whoops! Thank you, Tom. I was looking at the picture of SFRD 4100. The reefer book says that all of the members of Rr-19 had Dreadnaught ends except the first two. The photos of Rr-19s that I have

yes. somewhat. I find its how you lay the pattern in the mold. If from the center out the shrinkage is greatest. As the mold shrinks in diameter. around 2-3 %. But will grow as it

For those of you who use rubber molds to make castings, is there shrinkage? Is it predictable? Does one build oversize by some percent to create a master? Does anyone ever imbed other materials in
