I've got all the fiddly bits set up right. Has anyone got photos of one
they've made up somewhere?
What prompted the build: a pal came by with a blade that was
broken;
I ground the ends and butted them together on a corner of the welding
table
(awkward), then whipped out the tig torch and voila! Poof! No blade! So I
needed a nice brazing jig. I guess grinding at an angle is not
recommended
either, yes?

Grinding at an angle is the way to go if you're going to silver-braze the
blades, which is the traditional method. I've been using it for over 30
years and I much prefer it to home-welded blades. The brazed joint is much
stronger than the parent metal and the finished joint is smooth.

However, I don't doubt that someone who's really good at TIG can do a fine
job. It's just that it isn't necessary.
To do the scarf, I put the two ends together, apply vice grip and hit
the bench grinder to give about a 30 deg. bevel. Doing both ends
together will ensure that the bevel is close to the same on both ends.
Don't worry about matching teeth.
