Curt, it looks like at least one of the tooling sets is coming back, thanks to some help from a local bolter. I don't mind offering that kind of help, and I've had very good luck with the loan program until recently. I have learned that the deposit needs to be big enough to assure that the tools get returned, and a specific time limit needs to be understood, though!
I'm also working on some tooling for my own shop to do the full-circle rear oil seal for stovebolt engines, but that one is going to be a situation where someone would need to ship their bare engine block to my shop. With the right adapter plate bolted to the back of the block, a cylinder boring bar can be used to cut the counterbore for the seal.
