I have several computers...I just don't store photos of techniques or finished work on this one. Nevertheless, as requested...
As mentioned, I haven't done this in a while--no call for it. So it took me about 20 minutes to get set up.
Once set up, I made this split storm welt in about 15minutes (click to enlarge):
It's only about 12 inches long but it was for demonstration (proof of concept) not for use--I don't know where I would use it.
Grainside at an angle to show "storm lip."
Storm lip split to 6 iron
Outside/outsole edge split to 6 iron.
Fleshside showing inseam/thread groove (unnecessary)
Interesting.....Thank you for your time.
Just courious, do you do that with a knife -or- are there other hand tools used?
