This is one side of the hobby I am discovering, and I really enjoy it. I dug yesterday few patents from Mr. John. C. Wahl. The manufacturing process of the "All-Metal Fountain Pen" is described in great details.



I was wondering if our resident repairmen ever refered to these documents.

Denis.

Pretty much doubt it. As I have attended courses in Workshop Technology, I have to say there isn't enough information there that will allow a machinist to make you that pen. Although that page is not the only one, I doubt that there is one where detailed dimensions is given. That information is critical. Without it, the pen is not possible.

I was thinking of repairmen. The documents describe with great precision the inner machanisms of the pens. It seems like it would be a great help when a never-repaired-before model comes in.

Denis.

Oh, in that case, probably yes. It does come in handy in that the patent does describe every part and what goes where.
