Wow! You used an expensive shop to do the machine work. I talked to Lloyd Creed, who had Case castings, and he gave me a contact to a guy who'd had one built using his castings. I talked to the customer and he said they had about 100 hours of professional work into it. Their cost, including a code boiler, was just over $30k. This was about 4-5 years ago. I talked to a local machine shop here in AZ after that, and got about the same answer. I do know that, at that time, some of the parts that needed to be made from scratch, were to have castings available shortly after our conversation, so several hours of the build time would probably be eliminated.I had my bull gears made for my 1/2 scale 65 hp Case that was operating by 2009. I say operating because it still needs painted and a lot of detail work like "Frivits", the back step, bunker doors, etc. I bought the last set of castings from the company that bought the patterns and castings from Ternings. The man made a pattern and had them cast and then machined the teeth on them to mate to a Boston Gear. I had to have it made because the company that bought Ternings stuff used all of the sets that Ternings had. The man that made them has since passed and everything has been sold off including the machines he made them with.
I would like to let you know that if you have your own shop you are looking at about $30K to build a new engine yourself with a code boiler. If you have to pay for items to be machined you are looking at around $65-85K with a code boiler. Please don't ask my wife how I know....
I was just providing a reference point for what a new engine can cost if a person does not have the skills or a shop to perform the work.I talked to the customer and he said they had about 100 hours of professional work into it.
They are out there, and the people that know about them usually don't say anything because they usually want to buy it themself.I think that finding a used engine is hard. if you know of one hit me up!
