Does anyone have a formula for figuring kicks? I always just bend what I need and correct the kick till its right. There has to be a way for calculating the shrinkage when kicking or is there?
 
Re: kicking...

I don't think there is any way to figure out a kick other than trial and error.

For this reason I don't like kicks at all, and I avoid using them. I much prefer an offset.
 
Re: kicking...

Use the offset formulas and leave off one bend.

Pete why add more bends than needed?

Kicks have their place.

Actually, there is a formula for kicks....I'm running out the door right now - so I'll post it later.

That doesn't work.
Offset is simply the cosecant (correct me ??) of the angle, ie 30 degrees is 2.

If I recall, a kick uses the tangent.

Like I said...on my way out, will post it later.

To each their own. I'm not saying I never use them, quite the contrary; I use them when necessary. But I don't like the appearance of kicks and I would rather use an offset.

I use a tape measure. The top of the pipe should be X inches higher than the measure of the pipe when starting the kick. X = the desired kick.

I agree that an offset has the more desirable appearance, but if I'm approaching the max number of degrees bend between pull points, I'll use a kick in a heartbeat.

True enough, but the original poster is attempting to figure inches of shrink per inch of kick dimension. I always thought it was 1/2 of the offset for approximately however many degrees the kick is. It will be interesting to learn how this hashes out.
 
Re: kicking...

mdshunk, I didn't mean to give a smart answer I just didn't go back to the original post. If you are kicking, it is most likely in conjunction with another bend, most often a 90 degree bend. Making this a kind of bastard offset. So, if you are going to calculate shrinkage the you will have to calculate both bends. The 90 and whatever the kick is. So you are really back to an offset. Try this offset calculator: scroll down.

Re: kicking...

Kicks to a box are at 10 degrees on your bender multiply your kick 1/2"or (.5)x 6 is 3 " measure back 3" from first mark and do an offset at 10 degrees perfect kick everytime.
 
Re: kicking...

While we're on the topic, anyone got any handy measuring tips for measuring and bending "rolling offsets" (offsets that roll to one side at the same time).

Just measure it on the "roll" - diagonally as if the pipe was in place, the set height is the offset/roll measurement.

Running out again...I'll post tom'row for kicks.

That's hard to do, particularly if the points are far apart. Sometimes, you almost need two 4' levels extending off both points and a measuring tape. That takes about all 8 of my hands to do. I thought there might be some easier way.
