Making a Sears Chief chain ring

[John]

I have two originals with out the D

Not sure what you mean by the step down. If you point it out I will correct it.

John, if the first pic is one you produced I am interested in type of metal used and procedure to patinize it, also can I see the shop next time I come out? Rick

There is a ring around the outer edge with scallops between the each connecting point, (think profile) then there is an inverse curve which rises up to a somewhat "flat" section before dropping down to the teeth. This "flat" section on mine is 1/32". I think that over the production period, there will be variations in the stampings? Also, pics tend not to tell the entire story.
Carry on John!!

you can also tell by the slight rolling of all of the edges caused by stamping that the new one doesn't have.

 

[John]

That roll is on both sides. I think when it gets polished for plating it will have the same look. I will post after plating.
