I love the offset turning, dont happen to have a vid of that thing spinning do you? It is impressive to see even that little of a part spinning on the offsets I'll bet it is slow going until things get roughed out!

It is fun. The failures are just practice.


Sorry but no video. I had a few go bad before this one so I was concentrating on what I was doing a little more than normal. It was slow but the whole piece from start to installed was only about 8 hours not counting making the main bearings.

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.

Pistons
rods
rod bearings
rings
distributor
cap
rotor
sparkplugs
flywheel
balancer
motor mounts

I think thats the bare minimum. Don't forget to include the 4 or 5 things I forgot. I figured one year but then I started 2 of them so 15 months is more realistic. I think I'm 9 months in now.

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.






Started on some pistons. Machined up the blanks and put the grooves in. Then the parts were rotated and the blank was faced to size. I also machined a boss to hold the piston until all the machine work is done. My bore is .6245 so all the blanks are between .6230 - .6235.

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.

I mounted my chuck on my rotory table and ended up with .0007 runout. I have never been that close before so im trying to get everything done that requires rotation before I take it back off to do some CNC work.


Started on the distributor body. The part started out as a 1-1/5 inch round bar. Made some cuts until I ended up with this.




Then I made the slot between the body and the hold down flange.




The end was drilled thru and the bearing pocked was bored.






Went over to the mill and cut away everything that wasn't hold down clamp. Then the slot was cut for adjustment.






The piece was then put back in the lathe where the top was finished to 1 inch. The recess was bored and the top bearing pocket was formed.




All that is left now is the largest diameter needs to be milled away to form 2 holding tabs to secure the cap onto the distributor.

I just looked at the pitchers & thought "That looks like it's about .0007" out!" before I even read your post: Not really. Chris

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.
