It looks like the port faces on the Stanley could have been done with a shaper on the full size but the issue for the one off builder is the ports which would have been cored during casting and would be very hard to machine on a miniature let alone full size.If you do go with "Big Marion" My personal thoughts are that the crankshaft bearing supports look to be on the light side and compared to the cylinder/trunk guide part of the engine they look small, if doing it as a mill engine then I also think a larger flywheel would be more in keeping, what looks like a 4" flywheel is quite small for a 1.5x2 twin, possibly drop the whole engine down and have a slot in your display base or model a brick or stone base which would also reduce the need to have the engine raised on those legs. A lot of the RC truck and heavy plant model makers do use mini hydralic rams, it is a very popular hobby on mainland Europe particularly in Germany. Even some of the ready to run stuff is packed with functions that you could possibly transfer to yours rather than start from scratch
Wow that Ward! Great that you have the prints, and great work on the 3D model. That would be my choice but I understand it is a long term project!
Cutting the port faces on the full scale version. -Doug
Have you any other photos you can share ?
Doug, does the cutter mover back and forth, as on a shaper, or does it spin as well??
Hi Doug, Thanks for the info, those 2 photos of the sectioned engine are great!Now as to not posting more photos since this is a model site... oh yeah they would be for research for Chris’s build! Here’s the one Dads been working on....Cheers Kerrin
