For those that might care I have been working on a twin crankcase for the two 33cc engines that I have. The sketches are rough and not exact but the measurements are exact and in MM's there are still a few bugs to work out. The bolts on the crankcase shown on the sideview will not be in that location on the final design and the rear of the crankcase needs a little more meat for a mount. I can use 2 3 1/2" x 3 1/2" x 2" pieces of aluminum for the front and rear crankcase halves, that will give me plenty of work area and still need quite a bit machined off. It his hard to put ideas on paper but seems easier to visualize it as it is being made. I have my new HF 8X14 lathe but have not had a chance to set it up, it is still sitting in the crate on the floor, I also purchased from LMS a hand full of HSS bits and boring bars. I think I may be able to use a drillpress with an Y & Z vise to machine out the stock, any ideas? This is just a project in the makings, if it does not work out then I will just chalk it up as a learning experience. This project will be a long drawn out one for the simple fact that I only mess with it in my spare time. I still need to locate a set of reed valves and all needed pieces of it before final measurements can be made, it seems the old Homelite models will work and have located several good used ones that I need to go get.
