Well, I've made a decision! 
Seeing as how I have at least 7 engines and 2 locos that I've started and stalled/abandoned to start new ones..... ;D I've decided that I'm not going to start a new engine until I finish all, most, some, at least one that I've started. So....
Here's a couple of wobblers I started on several years ago. Not sure why I ended up making two, I started out with just one. Anyway, first pic is where I left off. I think I was scared of the ports. Well what better time to get unscared.
Todays progress: Layed out and drilled crank and pivot holes. Almost in the right place. :-\ Made up the obligatory port gauge and marked out the ports. The plans call for the inlet port to be .344 deep and the exhaust straight through the back. The round back!! I suddenly had visions of breaking drill bits. Well, no good way around it so into the mill and it went right through. Wow, I guess my fears were groundless. Drilled the intake port, one down. Mounted up the second, drilled intake first since it was close, moved over and started the exhaust. No problem, till 'snap'. :wall: Got cocky I suppose. Surprisingly it didn't break coming through the back, it never got that far. Pulled out a small piece of the bit but the end remained. ???
After some sitting and thinking I decided to try putting a side port in like the intake in hopes of maybe catching the broken bit and popping it out. (i know, i know) Well, set up and drilled the intakes, started the exhaust waiting for something to go crash... All I got was tick, tick, tick when the bits met. Hmmm. Pecked lightly a couple times, it's not coming out. Oh well, maybe I can pry it loose with a pick. Grabbed the magnifier and Holy C**p, the drill tip is past the hole! I broke into the port! It's saved! woohoo1 I can do anything!!!
It was at this point I decided I'd better call it a night before I tried something truly stupid.
As an aside I think it looks better with a tube on each side. If I'd known that before I drilled the first one... Maybe that why I'm making two?
Havin' a good ole time.
