Brian, that material looks like copper? Is that suitable for a bearing?

Hi Steve

Thanks for the heads up, it was ordered and delivered as PB 102 phosphor bronze,  it looks red but is very hard. not sticky to cut like copper.

Here are the photo's of the finished article .

Trying to get some time in on the project because I am going to Scotland for Christmas and new year to see the kids

To lube the big end a drip feed oiler will supply oil to the outside of the crank flange centrifugal force will spin it out into the collector ring and then pass it into the bearing,

Hopefully good lube with less mess.

Fiddly jobs today,  balance the crank, and fit the pins to the connecting rod, Only the threads to retain the flywheels and the keyways to do and the crank can be assembled and pinned,

 Boy will that ever be a relief !!!!

   

Leaving for Scotland for the holidays to see the grand children.

Nice work Brian.

How are you planning to pin the crank? Axial dowel pins on the mating diameters?

Hi All
 Back from windy Scotland  to a freezing cold Sicily, now that just ain't right.
however I returned with two 1/2 X 20 nuts for the flywheels so it's time to threads the crank ends.

   

Then cut the keyways for the flywheels
