I think I will stick to locomotives!
I have a big intrest in the quartelscale merlin engine. But found out the castings are not avalible anymore.
I had contact with a danish builder who built on of this engines and got it running.
He told me that from what he have heard about 50 of those casting sets were sold. Only few of them completed them.
Is there or does somebody on this forum knows who has a set of castings and would like to sell them.
Hope i could get a set of this.
I have a complete un-touched set, plus valves, guides, seats, retainers, and keepers.

Hello, I really need this drawing very much. I love it. Do you have any plans to sell it?
I'm sorry but it's copyrighted material, and I can't supply it. Others have been down this path trying to purchase the drawings from the original author even though the castings are no longer available, but his position has been firm and he won't allow them to be distributed outside the casting set. Your best bet is to purchase the set of castings and drawings from Randy above. You're going to need the castings to build the engine, they are very rare, and if Randy is willing to sell his you may not have another opportunity.
I don't know what your skill set is, but if you decide to purchase the castings and go on with the project, you should get a few other engines under your belt before attempting the Merlin. It will take only a single slip up to ruin an irreplaceable casting, and many of them will require straightening. Best of luck to you and keep us advised of your progress. Everybody loves a Merlin. - Terry
Randy？Excuse me, who is it
He's the person you communicated with in post 843 above.
By the way, I happen to remember that there was a change to the crankcase casting that ended up making later versions of the crankcase slightly longer than earlier verdions. There was a warning about this issue on the Dynamotive website when it was still active a few years ago. This casting modification changed some rod locations from what was given in the drawings. Mine happened to be one of the ones that required these changes. In fact these changes rippled on up through the entire engine. So, before you start machining the crankshaft, make sure you have the actual crankcase casting that you'll be using in your hands. - Terry
