4 Cylinder Inline Engine

[rdean]

I machined 4 connecting rods on the CNC today but it took me twice as long as it should. There was a power glitch that spoiled one of the rods and I had a couple of senior moments.


Made some slots for the rod bolts to set in and then halted machining for the day.


One last thing I wanted to get some paint on the crankshaft before it started to rust.
Looks pretty nice.


Thanks for looking

Great looking work. I will definitely come see/ hear it run.

Thank you Tom you are always welcome.

Spent the day working on the connecting rods.
First was drill the holes for the rod bolts.


Then cut the ends off and tap the threads.


The needle bearings I am using have a rather thin shell so not to squeeze them too tightly with the rod caps I used an expandable reamer and an extra bearing for fit.
Once I had the first rod cap size set the other three were a piece of cake.



Thanks for looking

Looking good Ray!

Looks good

Thanks Boswell and Chris for the kind words.

The crank looked so nice and shiny that I decided to paint the engine block.



I have this triangular piece of aluminum left over from my 5 cyl rotary build. It is too good for the scrap bin but it never seems to work for what I am making at the time.
So nothing ventured nothing gained.


In there somewhere are four motor mounts
I just need to get rid of the other bits.
This is fairly close to what I imagined.


Thanks for looking

Looking forward to seeing the mounts.

I did a little more machining to thin the web, cut off 4 pieces and milled to equal width.
Did a polish job and installed on the engine block.





This engine has a solid foundation.

Thanks for looking.

Looks great even if it is Ford blue. Lol
I personally would have gone with Chevy orange.

I was going to use Allis Chalmers orange but I already have two engines painted that color
This is Royal Blue from Ace hardware but it is close to a Ford color.
