hello gents, a couple questions: I'm planning on working with bosses. 3/4, 5/8 and 1 inch. are for which applications respectively? I'm planning on ordering from paragon. building the fork with 28/20. the rear stays are nothing special/same ol' same ol' .

what would be the downside of brazing bosses on for "future" use.. if they're ss with screw out studs shouldn't matter right? other than looks.... ?

does anyone have any photos of boss jigs you've made?

thanks fellas,
adam

Unused bosses are kinda ugly, but that an "eye of the beholder" thing.
The 3/4 and 1" bosses are for forks and the 5/8 are for seatstays.
It's best to get the unmitered bosses for a fork. Because, if you're building with a cast fork crown, 80mm usually falls just outside of the blade centers...meaning you'll have to file the bosses to fit and too much filing on the mitered bosses will make them too short for the studs to fit.
My first boss jig was a flat piece of steel (a guide from a chainsaw file actually) with a slot and I bolted the bosses to that.
Then I found an even simpler and slicker solution from Dave Kirk:

yeah, he rocks.
Thanks for this one Dave!

For a jig , i made a strip of flat bar , drilled a bunch of holes in it, the last 2 I turned into a slot, so the width is adjustable ..
It, being flat, kept the bosses parallel to each other,
when I brazed them on the tubes were sitting horizontal.

+1 for the strip with a hole and slot. I've got a Henry James brake boss jig, and really never use it, because the strip does the trick.

Live Wire did you post a link for Dave Kirk's solution? I'm not seeing it.

No link, it's the picture I posted of the jig made out of square tubing. With a nice slip fit and holes the right diameter that just barely fit the posts, that jig is a lot easier and faster to use than the flat strip and bolt kind.
I had an HJ jig too, very nicely made and useful as an alignment checker, but I sold it because my homemade jig worked so well.

It's a "red X" for me, and when I copy and paste the "properties URL" https://www.velocipedesalon.com/forum...-tools-cb2-jpg I get a Velocipede Salon web page with this message:

thanks gents. i saw the photo, i'm also a member of the other forum..maybe why i can see?

Has anyone used the paragon bosses? Is there a downside to using bosses in conjunction with short reach caliper? will there be issues? These questions may seem elementary, sorry.

Ive been tasked with this and dont want to destroy margin with return shipping, wasted labor..etc. thanks guys!

yes, you have to be logged in to that forum to see pictures. Seems to me that a caliper is going to be awfully close to any boss.

OK, I thought if I could see the pic everybody could...oops.
No idea why it did that but for everyone else I got one of the "in progress" frames in the shop and shot a pic for ya:

Nice work - simple is good.

thanks everyone! we've nixed the idea of going both routes. Classic case of I want one that does everything.
