[GreenKeys] M28 LPR Print hammers...

[Paul Heller]

Wonderful. I sure hope someone can make these. There are a lot of us who could use them, me included!

Nick, I think you would be overwhelmed and probably burn out your printer (as well as yourself).

I wonder if we can find a fabricator out there? Maybe the same source Dave W5DT used? If not too expensive I’m willing to fund it. I bet “order processing” and shipping for Dave did not go all that well, so we need to figure that one out. 

In searching back through old messages I found on where Don K9TTY wrote:
"The originals were made out of Delrin. a yellow translucent material that stretched over the print hammer.
I have to double check, but I think the part number is 173979”
