Interesting John. Good job. By the way? what is silver steel? The price of regular steel around here seems to be worth the price of silver.

I believe silver steel is what we would call tool steel such as O-1, etc.

I thought silver steel was what you guys call drill rod but I may be wrong.

I used a similar method - drilled and tapped for some pins I made then brazed and filed to shape (back gear):

Drill rod is tool steel. The "O" in O-1 means it's oil hardening, "A" is air hardening and "W" is water hardening tool steels. I'm sure the experts will correct me if I'm wrong here. Smile

What is D-2 tool steel then? Not trying to be a smart ass just wondering. I don't know a lot about metal grades but have seen lots of knives that were D2.

different alloy but still tool steel

Silver Steel I believe is a name that came from the UK here most call it drill rod which is what it is alloyed for, The Silver comes from it being nice and shiny, but I may be wrong

Silver steel & drill rod are the same
Alloy steel with a ground finish that can be hardened & temperd

Just to say most 'Silver steel' in the UK is for water quenching. So it is the same/similar to W1 drill rod.

I cant find any pictures of the finished job but it worked fine
John

It is all coming back to me now
The plugs were 5 mm cap heads screwed and thread locked in place cut off then filed to shape
