Microwelding for ejector repair

[B. Dudley]

Stan,
I think that what your screws are most lacking are the light cuts that go in the same direction of the screw slots. That is done with a fine comb. It looks like the edges of the slot may have just been peened down to clean them up some which lightened the comb engraving.

[Dean Romig]

Brian, please describe a “fine comb”. Is this some kind of engraving tool?

[B. Dudley]

That would be a question better asked to an engraver I guess. But yes, it is a tool that lays put the evenly spaced shallow lines.

I once gave Geoffroy a new screw to engrave at one of the shoots and it had the fine shadow lines on it like that. He could not do it there and had to take it home because he said he did not have the “comb” with him to do it.

[Dean Romig]

Thanks Brian. I hadn’t seen the comb engraving on the screwhead itself but they are very obvious in the flower petals surrounding the screws as well as in the foliate engraving forward of the trigger plate.

It is very common along the screw slots on Ithacas, Lefevers and graded Foxes. Of certain eras of manufacture.

The Parts legends from Meriden Catalogs lists this part as being called a "Roll".

That may be but the Ejector Patent names it numerous times as the: Joint-Block.

[B. Dudley]

Ok. I was wondering where the joint block term came from.

Brian,

This a picture of a NIB NID, I believe I understand now the light cuts you’re referring to.

Stan, I would have liked to help you out with your question but I am not very familiar with a comb.
