Hey, Im building yet another engine in my class, It is called the Micro Hosc. It is a TINY air powered model engine
We dont have the tooling small enough to make this model so I had to go out and buy all the tooling for this model on my own
I got most of the tools in the mail today but I am waiting on some other drill bits to arrive which should be here tomorrow or saturday
Here are two #80 drill bits, they make a whole that is .013 and 5/10s of an inch in diameter
