I couldn't find any 5 cylinder radial engine designs that were free, and also the lack of tools right now (4 jaw chuck for square bar cylinders) I decided to design my own from scratch. The proportions of my design just didnt look good, so i decided to try something out of the ordinary; an 8 cylinder radial engine.
There are some of these engines out there, but are not as common as the 3,5,6,7,9, or 15 cylinder radial engines, and that's what I like about it. Using some of my spare time at my university, and the machine shop that we've used for some of our classes, I can start making parts until the end of the semester, before i get my own mill.
Pictures so far:
The crank case is made out of 6061 B221 Aluminum.
Mounted in a rotary table, using a 1" carbide insert face mill i started the task of milling the octagonal shape.
I swapped out the 1" carbide insert face mill with a 1 1/4" face mill; just to give me some more leeway when parting. First side complete.
Second side complete.
Third side complete.
Some more views.
Will finish on Tuesday.
