Bend Angles

Post by joegoat » Tue Aug 01, 2017 7:44 am

I'm enjoying my run of straight pipes right now, but a question came to mind the other day. When it comes to 1/4, 1/2, 3/4, and full bent pipes what angles are associated with each category? Has someone set up a standard for what angle range determines the fraction of the bend?

I think it just approximately dividing the parts of a quadrant of circle by whatever proportion.

Full = 90°
3/4 = 67° 30'
1/2 = 45°
1/4 = 22° 30'
1/8 = 11° 15'

Probably only Oom Pauls approach full bent. Just my opinion. YMMV.

This was my thinking as well. I also agree that only Oom Pauls approach full bent, but rarely are at 90 degree.

Where exactly would you measure those angles on a pipe? Visual aids are welcome.

Moana teaches the pipe-carving angles.... relative to the horizon:

This. The angles are imaginary lines intersecting the shank and the bowl to a point where they meet. They are also approximations.

I'm thinking place the center line of the chamber at a right angle to a surface. The surface would be at 0. The angle/bend would be measured from the surface to the centerline of the shank.

Had only I read the rest of the replies. At least I'm in line with the rest of y'all.

By my reckoning, you're all saying that a full bent pipe has a 45 degree angle.

I'd have no problem calling this one a half bent.

So, if we use the y axis created by the tobacco chamber as the anchor for our shank angle determination and the point where it intersects at a 90 degree angle as our x axis, the line created by the stem midline creates an angle in relation to that y axis that determines the degree that the pipe is bent. On a full bent pipe, the imaginary line that the stem takes would be parallel to the y axis or imaginary line the tobacco chamber makes. Here's an interesting illustration of an overbent pipe which was my intent in this design:

Welp, I had a glorious theorem all typed out, regarding my conclusion on this subject and fat fingered some freaking button. It all went away, browser window and all.... Maybe I'll try again tomorrow. Nice pipe Wayne!
