Nice!

I love your use of "don't have the part so I will just make it instead"! The engine is turning out nicely. Awaiting the video  :clap:

Well, a little update for you all.

I started today with the air-hose adaptor that I started last post, I drilled the other end and tapped it M6, and then I milled a flat and then drilled and tapped M4 for the air-hose-barb-thingy.



Then back onto the lathe, I chucked a 6mm brass rod, and turned a 5mm to 3.5mm taper on the end. This is gonna be the inner tapered pin that will block or let a controlled amount of air through to the air outlet.



Then I threaded the rod M6, and then knurled the end

(notice the slight mess-up on the threading, I hadnt got enough of the rod sticking out and didnt match the thread up well enough during the 1st pass on the 2nd section  :doh:)


But when put together it fits and works ok. There is a little leak of air from around the knurled/threaded area when the home-brew valve is open, but not so much that would bother me at the moment.




I then made up a round base out of some ali bar I had, drilled it and counterbored for the mounting screws, and also drilled and tapped a center hole M6. The center tapped hole is for mounting the Ali base onto a wider turned wooden base that I plan to make. (if folk are interested I'll do a project log on that too)
Here's the little wobbler on its little base.





And then, (drumroll please)





It runs  :D :D :D :D :D :D

Here's a little video to feast your eyes on. (please ignore the stilted voice-over and the overly long presentation) (sorry bout the link, I can't seem to embed the video, I have the code for embedding into a webpage but it doesnt seem to work on the forum)
