Today I have made the final set of lamp irons for the 8F and thought I would share the method because it occurred to me that while I have used the mill the same result and basic method could be followed by someone with a file.
I started with some flat nickel bar

I cut off four 40mm lengths and soldered them together.

Once soldered together I milled all the edges flat. I needn’t have done the ends but with the mill it was a simple task. Here I have milled out the front of the iron.

Then I turned the block over and milled out the rear

This is the finished job before cutting off with a piercing saw and separating them.

The finished individual lamp irons ready for final clean up with a file.
From the 40mm strips, I got eight lamp irons and I have enough material left already soldered together for a further eight which I will cut and put in the spares box.
