Bevels

[holdpt]

We have drawings requiring a 71 deg bevel on 1" plate. Basically, it is a slope where 1/2" and the 1" will meet. Does anyone have a good idea how to accomplish this 2 3/8" wide bevel without distorting the material with excessive heat? To make matters really intersting, the material has a 27' radius.

Thanks.

What kind of material and how are you proposing to make this bevel??

Wood and a router or titanium and big A$$ grinder??

LOL. Good point! It is A36 material. I am trying to stay away from the Big A$$ grinder! Too many to do.

A good CNC machine and operator can do this. Call your local machine shop(s) and see what they say.

Milling a bevel like that is easier before the plate is rolled.

Also, there exist 'pipe beveling machines' that can mill or grind a nice bevel after the plate is rolled.

We have one of those rotary plate bevelers that works like a shaper,
and while pricy, they put down a perfect bevel in a fraction of the time it takes to grind it. Well worth the money.

Sounds like you are fabricating a structural component of a tub girder.
