This is a great blend of 3D printing along with excellent machining. It appears seamlessin the photos.

 :hi: Clodey,

Maybe when you see some of the scale model motorcycle engines people are making on here it might inspire you to make one of your own  :)

Introduce Yourself / Introduction for Clodey.
« Last post by Clodey on Today at 11:47:35 AM »
Hi, I am a retired (68) Toolmaker/Machinist/Fitter & Turner, that started in GMH (General Motors Holden) in South Australia; pre-computer. I have many interests in all things in the engineering spectrum, but, Steam & aero engines are up the top. I am not into models myself (i'm a die-hard petrol head motorcyclist), but love looking at other peoples projects. especially when making things smaller that work!
Regards, Clodey. :)

Nice fuel tank you fabed up there, Ron.  And the base looks great too.  You're going to be done with this before we know it!  :ThumbsUp: :popcorn:

The handle is only inserted to move the pawls, then its removed before starting the engine. There are holes all the way around the light blue disc, so they can pick a convenient one when they want to change the pawls. There will be a brake band in the groove on the far side of the pink drum, to hold the drum from moving when changing the pawls.

Ah... THAT's what I was missing!  The handle doesn't stay in place, and you don't change the position of the pawls on the fly. They're either engaged or not, when you start things up.  OK, that makes sense.

Besides, changing the engagement of the pawls on the fly seemed a little iffy without some kind of clutch mechanism there.  Seems like the ends of the pawls would get chewed up - or the inside of the yellow wheel, or both.

Makes a lot more sense this way!  Thanks for the explanation, Chris!

The next projects have been a new and better engine stand, and a fuel tank along with its mounting columns.

The fuel tank started as a brass pipe nipple that has been in the junk drawer for years. I turned the threads off, and bored it out slightly to clean up the inside and increase the volume a bit.


The end caps and filler cap were basic turning jobs, while the filler neck and the tube nipple were recycled from parts made for other purposes but not used.




The carburetor I plan to use, at least initially, came off of an Irvine 20 “Black Head” model airplane engine I've had since ~1980. I tried running it on my V-twin some time ago with success, so I know it can work. A vintage carb for a vintage engine.




I didn't take any separate pics of the new engine stand, but it shows up in this last photo. It will be getting a coat of paint eventually.
