Looking VERY goo.I used my CNC router to cut out the Con-rods from a sheet of aluminum plate. A few months ago I upgraded my CNC router table with a R-8 spindle head from Little machine shop. This was my first try at cutting aluminum. My old router spindle was way to fast to cut aluminum and it would melt the material. This new setup works great and I am looking forward to using it on future engine projects. I was a little worried that the slower spindle speeds would not work very well cutting wood. I was pleasantly surprised as it actually works better with no burning of the wood and a lot less mess.
All assembled without a hitch and everything turns nice and smooth. So on to the piston and rod assembles.

Amazon, see link below. It comes with 3 pads, I used my belt sander to make one smaller and another one with tapered sides. You can make your own sandpaper disks with a gasket hole punch.Where did you purchase the little pad sander?
I think you are referring to the brass bit in the top of the upper head. It provides a bushing for the rod and it holds the o-ring packing in place. Post 20 shows some detail.What is the brass circular piece over the main bearing with 3 holes in it?
Damn! that's nice. If I begged, lickt your boots and howled at the moon, would you give that to me?Bluing went well. The cast iron doesn't blue as nicely as the steel parts but It is passable. To age the cast iron fly wheel I immersed it in vinegar for a couple of hours. All aluminum parts are now anodized. All brass parts left natural.
So its time to assemble what I have made so far. I cut two sets of gaskets using my computer operated “Silhouette Portrait” paper cutter. I just love this machine, it makes perfect gaskets.
And the cherry on top, a 1.626” ball bearing.
Next step is to make the eccentric and all the linkages for operating the valves. The eccentric and rods will be made of steel and everything else will be brass.
Thanks for watching

Har har. That's a goo one. The farmer plants the corn, the processor harvests it. I do peas first then corn.No. And shouldn't you be planting corn.
LOL, and this was very relevant to whatever topic it is. (But I don't mind nor do I care.)That is what I like about this site. You never know what you might learn
