Well I am calling this one finished for the most part. There may be some more fiddling and tweaking, but it runs thankfully (I have enough paperweights already!!). Thanks to all of you who followed along on the build and offered your suggestions and support. Below are some photos of the finished engine. Most are self explanatory and a few have objects or my hand in the for size comparison. The only comments I will make are for photo 7, showing the two lights on the wooden base under the on/off switch. The left hand light is for power on, the one on the right if the timing light...when it comes on the hall effect sensor is turned on as the magnet comes closer to it. When it goes off, the high voltage is sent to the spark plug. Since the magnet holder is mounted to the crankshaft, this becomes a waste spark arrangement, firing again on the exhaust stroke but this causes no problems. The last picture shows the position of the crankpin when this happens. While I didn't measure it directly I would guess its somewhere around 15 degrees before TDC. This is where the engine seemed to be happiest. Video will follow in a separate post.

Great runner Bill and a good looker too

Very nice Bill !!

Good job!

b.lindsey · « **Reply #5 on:** May 29, 2017, 06:36:27 PM »

Thanks!! It does feel good to see them finally come to life...have to say though, this one put up a good fight these last few days. Sometimes I think there is a bit of black magic and luck to it, but I'm pretty happy at the moment. It's going to be even more relaxing to sit back and watch Bob and Dave finish up theirs now.

Outstanding job Bill! Myself I think being able to build something this small and have it run as well as yours is quite an accomplishment. You know there's always the drawings for the vertical!

Hi Bill, you have build a very nice little engine there. Following along the whole time and yes, the plans are downloaded at my hard disk.

Bravo Bill. A cute tiny engine.

Yes! Well done Bill; she really sings along. Congratulations on an outstanding build. It has been an absolute pleasure following your build as I crawl along with mine.

Another fine looking engine, with a nice write up and a good running manners from you Bill - thank you for the ride

Best wishes

Thanks everyone for the kind words. It was a fun project. One if these days I may make Arv's original water cooled version, or the vertical. Several other things on the build list first though, including finishing up the P&W. Like someone's signature line says...too many projects, too little time

Speaking of that Bob, I will be with you till yours is running too.

Bill

Nicely done, Bill. And well documented. I enjoyed following along.

The only thing we missed was you doing the happy dance!

Nice job, excellent runner. I like the hit miss. I enjoyed following the build.

Thanks Rudy and Kim. Kim, this is as close as I get to a happy dance these days...

...but needless to say, in my head I'm still dancing

Thanks Bob. We were typing at the same time.

Outstanding Professor. It's really a lively little feller. And, as your norm, the flywheels run as true as anything inside a Rolex

. Great job.

She's a runnah!

Congrats bud!

b.lindsey · « **Reply #22 on:** May 30, 2017, 12:42:02 AM »

Thanks Dave. Now I can sit back and watch you

Cletus, you know me well, flywheel runout drives me nuts. The one on the governor side is ever so slightly non-concentric but its not that noticeable and doesn't bother me nearly as much as side to side runout.

Excellent job Bill. I really enjoyed following along.

b.lindsey · « **Reply #24 on:** May 30, 2017, 12:48:42 AM »

Thanks GL. I wish I could get it to start by hand but will have to keep working on that. If you have any tips I am all ears on that count. Thanks much for following along.

Bill

Congratulations Bill, you've got yourself a nice little engine there.
Thanks for the work you put in to allow us to follow your progress.

Hi Bill,
The first Tiny I built I could never get to start by hand so I made a tiny ( no pun intended) V groove pulley and mounted onto the offside flywheel. I would wrap a short piece of string around it like the old pull start lawn mowers and give it a quick pull. It started every time and I didn't need the battery and airplane starter motor.

b.lindsey · « **Reply #27 on:** May 30, 2017, 01:02:14 AM »

Thanks for that info. George. I may just give that a try. The 12V lead acid battery and the airplane starter motor are about 5 times the size of the Tiny and about 10 times the weight. Even so it was just the trick during the process of getting Tiny running well, so thanks also for that earlier suggestion.

Steve, thanks for the kind words and for following along.

Bill

Thanks Pete and John. It's you guys and the members here that keep me motivated. It's nice to giveback some when I can.

Flyboy Jim · « **Reply #31 on:** May 30, 2017, 03:15:26 AM »

Fantastic Bill.

Runs great!

As usual....... I've really enjoyed your build thread and learned tons.

If you get a chance, and feel like it, I'd really enjoy hearing how your new Cowells worked into the project vs the Sherline lathe.

Yes, get back to work on your P & W! That might get me moving forward on mine again.

Thanks Jim....I think we both need to do that, kind of stalled out on it for a while.

Larry, thanks for following along, hope to see you again next year in Pendleton.

Thanks to you too Dave....how's that half scale radial coming along

Still hoping to see you at Cabin Fever.

The small ones seem to be more difficult to build. I keep making bigger ones.

Thanks Stan and Don! Much appreciated. Stan, I know what you mean, I do love the small projects but have to take a break in between and work on something a bit larger for a while too.

Something larger, hmmm.... A locomotive? Large traction engine? Steam powered lawnmower? Hey, that would be fun! Although the coal ash might set the clippings on fire in dry weather...

I know what you mean. My Tiny i.c. is a try at something larger.

I turn my back for a holiday weekend and poof you have the Tiny running. Sounds great, good job.

b.lindsey · « **Reply #42 on:** June 01, 2017, 03:37:36 AM »

Thanks Art. I ran it a bit more tonight a with a little more tweaking I am now optimistic I can get it to start by hand. It almost will now but not quite there yet.
