My greatest hope, for the moment, is that nothing is next. I hope to stay out of the machine shop for a couple of months and recharge my mental batteries.----Brian

Brian I can appreciate that - but I see this as a hobby "for relaxation and rejuvenation". At least that's how I see it. It keeps my aging Brain functioning. I really do enjoy your working methods and models, I have built one (maybe two) to date of your models.
It is a hobby, and I'm good at it. However, too many projects too close together without a complete break to rejuvenate a bit, and it just becomes work.--It isn't fun anymore. In the last 8 years I have built 29 engines and half a dozen things to power with my engines. I need a break for a while.
Enjoy your break - well deserved! Thank you for the real effort you have put out for the benefit of the rest of us. I personally truly appreciate it.

Being that I live in sunny, and extraordinarily hot Arizona, with no A/C in my workshop, I get to take a 3+ month sabbatical every year. But like Cymro says, I need that mental stretching and miss the hell out of my time watching the chips fly!
Anyway, I really enjoyed your build process Brian, and hope one day to have your level of skill!
Now, back to the sweating and dodging from one shady place to another!!!

Brian,
My question may be a very novice one but it has me scratching my head right now. I am in the process of turning a flywheel for this engine and my setup looks like yours in post #52. I have turned other flywheels on a rotary table to get a design like what you are working on but the "how to do it" question comes up with turning it in the lathe to be able to complete more of the work without changing the setup.
What tooling, and methods, do you use to end up with the nice straight contours that are shown in that picture? I am one of those "newbies" who only uses carbide inserts. I have never gotten proficient at grinding tools and I'm stumped by what you use to make what appears to be accurate plunge cuts to hollow out the mid section of than flywheel. When plunge cutting to the depth in your drawings (0.450") the tool holder contacts the radius of the outer rim. A boring bar will work to smooth out the edges (running the machine forward for the outer edge and in reverse for the inner edge) but what is the preferred method for hollowing out that section - and doing it cleanly and accurately.

Ikrestorer--Cutting away the recess in the sides of a flywheel is always a bit of a trick. I have a 0.120" wide HSS cut off tool. I have ground the heel away on a fairly sharp angle, leaving a long, very pointed finger of metal at the top side. I position the tool at 90 degrees to the face of the flywheel, near to the hub position I wish to maintain and plunge cut for about 0.100". Then back out, move the tool 0.100" and plunge it again. I repeat this until the plunge cut area is cut to full depth. then I can get a boring tool into the slot I have created and take cuts towards the outer limits of the recess.---Brian

Brian,
I tried using a carbide cutoff tool but the "heel" was what got in the way. I think I have a HSS cutoff blade somewhere in my stash. I'll look for it and see what I can make out of it.
I notice your Double Oscillator running a Crazy Joint. I built one of those from your drawings and it fascinates everyone who sees it (including me)! In an effort to make this thing as interesting as possible have you made drawings of the governor - and are they available?
I love building this stuff but people like you are my "shop teachers" - it proves that even at my advancing age it doesn't automatically come with wisdom.

Ikrestorer--yes, I have a twenty drawing set of the three ball governor. I sell it for $25 Canadian funds. If you go to Paypal and deposit $25 Canadian funds to [email protected], they will notify me and I will send you the .zip file. Be sure to specify that it is the three ball governor drawings that you want. Good Luck---Brian
