I am brand new to foundry/casting work. I realize these will not be a very good "learning" project. Just wondering if anyone would be interested in making 3 of these for me. It is a chainsaw cylinder for a hybrid project. Basically 4" cubed. Very flexible with pretty much everything regarding this part. Would like at least the first 6-7fins from the top. Intake/exhaust port with enough material to machine to spec This is the transfer tunnel area, I need to add some material to make that wider than the base. Roughly 1/8" Intake port ^ can me made rectangular shaped all the way to the od if it is easier. Exhaust port. Same here just make a rectangular block all the way to the back. No need for the shapes etc. Cylinder bore, combustion chamber. That cylinder is currently 45mm bore, my plan is to bore it out for a 52mm bore iron sleeve. Need to make sure the diameter between the fins is at least 61mm or 2.4" if it is easier I can provide the iron sleeve to cast in. I don't need any of the ports cast through the jug. Same with the holes, a solid block with the fins and general profile will work fine. Not in any hurry, if you are interested let me know. This is the first hybrid I built, had to make all sorts of spacers/ modifications to the muffler. My goal is to just do the machine work to the cylinder and have a bolt on affair anyone could do. Thank you Joe I'm going to go back to reading/learning all the stuff here.
