Banding Square Shank Help

[bayareabriar]

I have a square shank that is cracked and I wrapped a pipe cleaner around and it measures 1.90” in length. What size band should I get for the repair?

Any video link recommendations for repairs?

Thank you.

Thank you.

If a good fit matters to you, special tools and experience are required.

For starters, the shank might LOOK square in cross section, but it actually isn't. It's an irregular quadrilateral. With inconsistently radiused corners (edges).

While the band itself IS square... but with a larger opening on one end than the other (think four-sided cone).

Unless you have the metalworking tools to accommodate those geometric bits of nastiness---as well as some woodworking ones to adjust the shank itself---you're gonna end up with a mess, guaranteed.

Wish I had better news.

As George said square shank bands are a bastard. But not impossible, it’s easier to make a silver band for one out of sheer silver than it is to try to get a premade square band to fit one though. I do have some square bands btw.

Excellent knowledge. Thank you for sharing. I won’t be attempting.

This ^^^^

Why factories don't fight the battles I described when making new, pre-banded pipe models is by making sure the shank-end is dimensionally correct and exact for the box-O-bands being used. It's simply an extra step (so to speak).

Any square/diamond-shanked pipe that wasn't originally fitted with a band was casually shaped, though, "by eye" and not measured.

Result? Sides aren't parallel, sides aren't equal length, and corner radii aren't consistent.

It’s not an 81, but you have a 58 EK headed your way.
