Good progress - shouln't be long before you have a working Crank and Conrod assembly - they already look good in their almost finished state

Do you know chaps, even though nothing is soldered/joined together yet, there is a more than even chance that I am getting somewhere!

I like those odds!

Main Bearings

The supplied blanks machined to size.



Set up to slit the blanks having machined the long slots in the bodies. I just LUUVV my FB2 mill!



The two halves are different sizes: 5/16" and 3/8". In the interests of accuracy I slit them in that sequence, retaining the pairs. They are slightly oversize so that I can size them accurately later. I used a much finer toothed slitting saw to start with, but it had an argument with a projecting parallel...!

Very neat, nice work.

More on Big Ends

Much to my surprise and amazement, I have a piston/bigend/crank assembly that lines up perfectly with minimal clearances!
Some fine adjustment will be needed later...
It looks nice from a distance



A few pics.

Preparing the conrods for silver soldering. Cleaning with thinners and applying the silver solder paste.


Untouched by human hands! I've since given them a brush with the Dremel but that is all. I'm minded to keep the blued finish.


Ta Dah!!!


Trouble is, members will remember I made a serious mistake earlier with the bed plate: both of those cranks are too far to the right, so it looks like I will have to buy another bedplate!
