Another Internal Combustion Engine

[rdean]

I know the title is kind of vague but I really haven't made up my mind yet. I was thinking of a side shaft Hit Miss engine, or an overhead cam Hit miss engine , or a marriage of the two so I will just start and see what happens.

I haven't had a lot of shop time with 2 hurricanes and the cleanup afterwards. The tractor fan blade went through the radiator so I had to replace that and the wife keeps finding new projects for me to do but I'm going to start this anyway.
I have had these two weights around for some time and they are of no use like they are so why not make a couple of flywheels.



Now I have had good luck machining weights in the past to make flywheels but this time the outer part of the rim was very hard. Carbide inserts would just throw sparks and then give up. The sides machined OK but the rim was made from ???
I had to resort to the tool post grinder for a decent finish on the rim.



And the finished product. Two 5" flywheels with taper lock hubs.


It's a start.

Glad to see you back at it Ray.

Cool!
But I thought they were "infernal" combustion engines...

Thanks Boswell I am too.

Sometimes they certainly are.

I had started this crankshaft a couple of days ago. It has a 3" stroke.


It is assembled on a 12mm shaft with a loose fit and Loc-Tite 620. I used the lathe to hold everything in line over night.


This is after I installed tapered pins and cut out the middle section of the rod.
The shiny places are where I filed the pins smooth.


And painted and done.

This aluminum is what is left over from my 6 cyl build.


It was too large in all dims so over to the band saw.
First a 1 1/2" wide slice over the width.


Then two cuts to remove the angled piece.
The setup looks dodgy but it worked just fine.


Right off the band saw.


And after truing up all sides.

Your creativity in clamping things in the bandsaw never ceases to amaze me.

Thanks Chris it doesn't always work out.


I made a bunch of chips and I got rid of anything that didn't look like an engine base.
No end mills were harmed in this operation.


I really like the idea of a one piece engine base.
I may use this style more often.


I also cut out and installed the two main bearing caps.
