Straight 6 Cylinder Engine

[rdean]

Started on the other side of the cylinder block for the cylinder liners. After drilling 1/2" holes I next went with a 1" drill Bit.


Then with the boring bar out to 1.250 and a 0.100 larger lip on top for the liner to rest against.


I could see the connecting rods were going to hit the insides of the block so just cut out the sides.
That fixed that.


Thanks for looking

I have decided to make the engine block water cooled. I have one other model I had built that uses a radiator and water pump so active water cooling is not entirely new to me but will be another challenge.

Milling out a 2" deep section for the water jacket.


When I started with this aluminum block it weighed in at 8lbs and 4 oz.
After the diet it now weighs 4 lbs 11.5ozs.


I also made a good start on the cast iron cylinder liners.
These will be cut in half to make the 6 liners.

Working on the cast iron liners today.
I cut to the OD to size leaving a center section larger for the lip in the block. Then I cut them in half and drilled the center out to 7/8".


Bored the inside out to 1".


All six in a row.


I glued the liners into the block using high temp gasket maker and clamped them in place.

I decked the cylinder block to get everything nice and level again.


It looked so pretty I couldn't help my self but had to paint it.
Used Allis Chalmers orange.
What do you think?


Also cut out 6 rods on the RF31 clone CNC.


All in a row.


Thanks for looking

Thanks Chris

Working on the connecting rods today.
Milled out slots for the 4-40 rod cap bolts.


Drilled the holes for the 4-40 screws.


Always trying something different I ran across these from McMaster Carr and will give them a try.
"863iron-copper bearings are also known as Super Oilite® bearings"

I cut them to length on the lathe and loc-tite them into the rod end.



I will let the loc-tite setup over night before sawing the rod caps off.

Thanks for looking

Looks like you used 1/4" material for the rods. Am I right?

Very interesting!
