Amazing work. Do you have a pic showing the setup for turning the rod journals. I know the part has to be offset from center line but I have had a hard time trying to figure out how much you know to offset it. The camshaft seems to be the hardest part to make but probably is one of the easiest if you get the degrees figured out.

So each of the four outside holes are used to hold the workpiece and turn the corresponding journals. I guess it seems like a very simple concept. How did you figure out how far to offset each journal?

I'd guess about half the stroke,eh?

Ladies and gentlemen, we have a winner. Half the stroke from center. Just need to pay attention to cut the correct one.

The crankshaft is safe in it's new home. I made the main bearings and installed the shaft. It is a bit snug but it will seat itself in no time. There's going to be a party tonight.

Awesome day in the garage today. I made the flywheel which is nothing more than a big slug of steel. It is bolted onto the crankshaft with a 10-32 nut or i chose to make the optional output shaft. Never know but I might want to power a pencil sharpener or a blender to make margeritas at the next NAMES show.

Or maybe turn a fan to drive a wind turbine to generate electricity to make hydrogen from water to use as fuel for the engine??? (Sorry, I couldn't help it after reading some of those water fuel things.)LOL

Made a few more parts. I couldn't find a cool looking oil drain screw so i made one. I didn't want just a plain hex head screw.

　
I also made a PCV valve. I'm not to sure it will do anything but what the heck. It is a stem with a cap. In the stem is a 1/8 inch ball and a spring to help seal when the crank case goes negitive.

Did some CNC work today.
Started making my water neck that will bolt to the intake and connect a hose to the radiator.

　
Finished the flanges on my distributor.

　
Cleaned out the bottom of my pistons.

　
Made the fixture to cross drill the pistons. Simple thing to keep the slot in the bottom and the wrist pin hole square to each other.

[stevehuckss396]

Finished making a timing pointer so I can keep tabs on where and when the ignition is sparking.


　
Also made the disk that will hold the magnets to trip the hall sensor.

　
　
Finished the water neck. It's hard to tell but I milled a flat and then drilled thru to the center.

Machined up the fitting that the hose will connect to.

Soldered them up from the inside.

Then cleaned out the bottom again with an endmill.

Finished making ...

All very impressive Steve! Thanks for sharing.

Thanks Dyno

Heres some more for ya!!

SNOW DAY!!!!!!!!!!!!!!!!!!!!!!!

Finished my pistons on this fine day off. Finished the fixture by drilling the wrist pin hole. Drilled .032 larger for clearance.


Then it was spot, drill, ream, repeat.


Then the piston was parted off the little boss. Then VERY lightly they were reversed and finished to height.




I made a few spares in case I made a boo boo. All are useable. They were made from 7075 if anybody is wondering. I had a piece so I used it but 6061 would have been fine also.


I also had time to make the motor mount posts. They are the same as the Peewee mounts. I think I detailed how they were made in that thread.

That's nice.

Continues to inspire Steve. Well done.
Please keep posting your work.

just read through the whole thing. nice work. i would like to do something like this some day.

ill be waiting for a video of it running.

[stevehuckss396]

I decided to have some fun today and make a pattern for some thing I have been thinking of casting.
I used some lexan that was given to me. I pinned two pieces together so I can cast in sand.
Started roughing it out with a 1/4 inch cutter.



　
Then I made some horizontal passes with a 1/8 inch ball nose. Can see more detail coming out.


　
Then vertical passes .006 on center for a few hours.


　
Then to the manual mill to remove the extra off the bottom

　

[Zygoat]

Will it be functional?

[Perfect Circle]

NICE WORK!

[stevehuckss396]

Will it be functional?

Yes, 100%
