Yes, I had mentioned in a perfin thread that my research had seemed to show that perfins are still allowed by the US Postal Service (albeit small ones, only). I had done some looking to find a method to create such an animal, without success.
I believe making a light duty one would be possible without too much difficulty, but it is a project for another day year.
I thought that we were talking about a machine to make perfs not perfins. There is a site that describes how to make stamp perforations using a sewing machine - maybe you could adapt that concept by welding or brazing a number of 'needles' in some sort of configuration.
You can use a tracing wheel found with sewing notions in any craft shop. You have to press pretty hard, though, since it's not made to actually perforate. That also makes it difficult to keep a straight line.
Here are my latest Zutopia Post stamps, perforated with a $1.99 plastic-handled tracing wheel. I'll be replacing it with a more sturdy model for the next issue.

If rod222 was referring to my post...what I looked around for was a company producing custom perforators, for the purpose of making perfins. I was not looking for a device that would perforate sheets of stamps.
Why? To create some discussion about stamps. To make people look twice at envelopes from my company. Because I can. (In theory, I can...turns out to be harder to implement, in practice).
Employees have always been free to steal postage, in moderation, so it is not intended to be performing its true function as theft prevention. Guess that makes it 'philatelic.'
I don't often use older discount postage as postage any longer. They are worthless before affixing them to an envelope, and worth even less after getting a spray-on cancel fifty years out of date.
I try to use current issues, even though I end up paying face value for them. A perfin seems like it would add a little visual interest.
