a US one cent piece (penny) is 0.750 inches in diameter, or 19.05 millimeters.

(ironically, the penny is the only common circulation US coin that works out to a standard even fraction for its size, in inches)

First off, thanks to all.


George_Race- Plans are here: http://www.john-tom.com/html/ElmersEngines.html Tiny is #23 on the page. For "Teeny Tiny" I cut all the dimensions in half.


Here's the YouTube video of it. That will help with the scale of it. The air is supplied from a tire inflator, hence the noise.

It's funny, I don't think of this one as that small. I actually started on a 1/4 scale version of it which is half the size of this one. Had most of it done when it came to a halt when the #80 drill broke in the column. The mishaps always happen on the most difficult part when you're almost finished with it! At that size (1/4 scale), it's just plain tedious to remake it. (No cnc or magnification, just the dials on the machine.)

ttrikalin can verify how fun this all is. He did Tiny in both full and half scales as well as starting 1/4 scale.

I have an idea. Let's put a ring on the top of the cylinder and put it on a key chain. It should fit in in the pocket without any trouble.

Nicely done for sure :bow:

Congratulation Bob,
I had not imagined the size until I saw the video.
Regards,
