Today I turned my attention to the crankcase bottom. Since the crankcase is split I need some method of screwing the two halves together and I would prefer if I could hide the screws, the original engine has a one piece crankcase.
One possible idea is to hid them behind the side crankcase breather covers. I need to make sure: 1. I can insert the screw, 2. There is access for the tool to tighten it. 3. the slots don’t interfere with the side cover mounting screws.
I worked on the internal features. I want to have a baffle under the crankshaft, I need to think about adding features for it to mount to. I am thinking two pieces of thin aluminum sheet mounted in a “V” with the slot open between them. Simple. The baffle is intended to help keep the oil from frothing up so it can be pumped out of the dry sump.
I added some features to the front timing gear cover. I am thinking the housing for the magneto bevel gears will be a separate piece.
Spent the day helping the wife un-decorating the house, so not much time was spent on the engine model.
