Yeah, that's the shape that JLS was suggesting, just an arc based on an equilateral triangle, but it's not a parabola or catenary. I might be splitting hairs, but it doesnt look quite right to my eye. It's easy to do though and probably close enough that I doubt anybody would pick up on it or complain.

I think I could use that template.  I'll need to check that out next time I'm in.

There are always possibilities....

I bought this set for 9.99 shipped on ebay almost a year ago

I measure the center of my belt at the edge I want to cut and pick a curve that makes me feel good from my 10 dollar set and clip one half side and then I flip it and cut the other side. Comes out great. Dont know how I ever lived without these and they are great for doing more complex curves when chained together and clipping corners

That's a really good idea. Can you remember the brand or do you have a link?

Hey Martyn

The place I got them from sells a bunch of household goods and I checked but they dont seem to have them anymore but I did a "similar items" search and this is what came up. Even at 20 dollars its a good deal. I had to pass a file real quick on them but they have been indispensable time savers. I used to mark corners with a coin and then cut them out with a razor blade but they never really looked great and then I would sand them for 5 minutes. With these tools one bang in each corner and they are all even and wonderful and they work great on belt ends!

hope this helps

opps I should mention though it will be obvious .. they have some that are a full arch and ones that are just a curve. I bought the curved ones because I thought they would be more versatile but at that price I may get a set of the arched ones as well. The curved set let me do the little bit of detail like on the flap of the firestone on the sheath lickity split. I could have traced and cut out the shape but I have never had resounding success making it all look somewhat even.

Well, actually I was thinking about a die to hit all of this in one shot ...

Actually I don't think this is exactly really what JLS suggested. If I got his suggestion right. The arc radius is not equal to the width of the belt but is a segment of a much larger arc from three larger cycles centered outside the pattern Think Venn diagram where three larger circles over lap.

JLS I am having a tool and die friend make a template just like that (not a die) for just than and from the buckle end. "English-ish" point and round as well. If you are getting a die made why not get the holes as well or is that so you can place them yourself to length once the belt is tooled and stretched a bit?

And as for the partial arc punch set I have that sitting in my shopping cart and glad to here that for 10 bucks they are worth it. I just got paid so I can check them out tomorrow

Nah, I don't want the holes in it until AFTER it's tooled (the ones that are tooled).  I just want the ends cut quickly and cleanly.  Plus, on a narrow strap, punching the outer edge and the holes at the same time could certainly result in binding - which in turn can "booger" the grain of the leather.  It "could" be done, but you'd likely want a stripper to hold the leather down while the punches back out.  I mean a spring loaded presser plate, not the girl with no clothes ;)

Plus, you'd likely want it made with replaceable punches, too.  And I like OVAL belt holes, not round ones, meaning that the punches would have to be aligned somehow...

As you can see, that could get complicated ... !

yup good points all round.. not sure what's wrong with having a stripper in the shop though... just to have an extra set of hands to hold down the leather when needed.
