PICTIM ignition module runs fine on 9v smoke alarm battery

PICTIM ignition module running on a standard 9v battery for the past two hours.  For this demo, the PIC chip has been programmed to simulate a 4-cycle running at 2000 RPM.  Visit www.model-engine-ignition.com for more details.

Note: BUZZCOIL ignition works great on 9v as well!

Bob Cooke's V4 Update

Bob just sent me these photos.  Just a little ignition work, and it'll be ready to run.  Looking great!

Steve Gould's V2

Here's an e-mail I received from Steve Gould on Oct 3, 2016:

Hi Allen,

My Howell V2 engine is nearing completion, it’s a handsome looking engine and a bit more difficult to produce than my original assumption. There is still a number of steps to go before completion, but all the main parts are working fine and the cam gear train works very well. Here is a picture, it looks the part when polished!

Regards

Steve

Got this e-mail from Dave King today. His engines look and run great. Thanks for sharing!

Hi Allen
Just a quick note to say I have finished my third engine 'Vickie' and what a stunning looking engine she is.
I had all my engines running together today and have included a picture and a link to a Video. What fun!

My next project is the Ringbom - Stirling Pump Engine to keep me busy for another year.
Many Thanks

Throttle hole dimension question

Malcolm from Great Britain had sent me an email question about the 2-Jet throttle plan pages included in the V-Twin plans:

Q: On sheet 27 left side view there are 2 holes .100. from top and .570 from top and .265 from right hand edge.
I can't work this as to size, depth, threaded etc.  Can you help me with this?



A: Hi Malcolm.  Page 27, looking at the "Left Side View", I'll call the top hole #1, and the bottom hole #2. These are the two holes you inquired about .

For hole#1, the dimension reference is shown to the left of the "Top View": Drill .070 thru and tap 2-56.  Looks like you drill until you "T" into the larger .140 hole at a 90 degree angle.

For hole#2, the dimension reference is shown to the left of the "Front View": Drill .043 dia into fuel inlet, then drill .070 dia x .200 deep and tap 2-56.

This may sound childish, but try cutting out the Top View, Left Side, Front View, and Right Side, then tape them together to form a basic 3-D model, then I think it will mentally come together much clearer.

Hope this helps...
