What about offering two lengths, one for back saws and one for regular hand saws?

Dom,
I'd be interested in a set of templates, but for my purposes, they only need to be about 1" x 2" in size. I would want them to be punched with a 30 degree rake angle. I would only need the smaller sizes from 10PPI and smaller.

My last thought on length of the template. I say 18" long. 1) This is long enough for most back saws with the exception of miter saws.
2) The 18" length will also allow you to over lap by about 8" for those miter saws and 28" saws to make sure your pitch is consistent. You will have to move the saw in the vice anyway.
3) The 18" length will be easier to store in a shop drawer out of the way when not being used and help prevent rust. Of course, you can always drill a hole in them to be hung.
4) Less material used = lower price point, hopefully.
That's all I can think of at the moment.
Best of luck.

Daryl,
yeah, it took me long enough to get to them eh?  I think we talked about these two years ago. 
What did you use to punch the number in the saw plate? And what thickness steel did you use?

OK, now you got me curious. Why a 30 deg rake angle?

Mostly because I'm trying to minimize the number of blanks I have to keep in stock. You wouldn't think so, but this steel takes up a fair amount of room. Especially when you've sheared it to a set number of sizes (like saw plates).

Because when notching there is no need for concern about rake angles. And with the notching tool that I use, the 30 degree angle will match the angle of the guide that is part of the tool.
I'd like to correct the dimensions of the templates for my purposes that I mentioned in my previous post. A template that would work best for me would be a 2" square with a different PPI on each edge.
And The notches that you punch should all be the same depth but with different spacing. In other words, A template for say, 10PPI should be no deeper than the template for 15PPI.
I could even get by with cold roll steel. Say, about 18 ga.

OK, thanks for clearing that up.

2" square!  Pretty sure I can't punch teeth in a blank that small. I could punch a long piece and shear it to 2". But the minimum spacing between the clamp bars on a Foley's carrier bar is about 6" to 7"

I understand what you are driving at. And it would make manufacturing a bit easier. For some reason I'm resisting the idea because I have this picture in my head of these templates looking just like saw plates. Go figure.

When notching, the notches locate the gullets. We don't care about the teeth at this stage. Punching with rake angles would hinder when doing the notching, especially with the bigger teeth, not so much with the smaller teeth. But if your punched shape is the same angle on both sides, it is easier to center the file when we do the notching.
Also, you might give some serious thought to making your templates from 18 ga. Cold Roll steel or similar. The only concern here would be clamping a template and a saw plate in a common saw vise that isn't adjustable.
As for making templates for my purposes, it would work to punch longer ones with only two edges punched, but I would only use about 2" of a template. I would end up with a few more templates, but that's ok.

Dom,
My strips are made from .026" galvanized steel. Since they are soft, number stamps worked fine.

Take care,
