Precision Radius-of-Bend versus old cosecant method for bending conduit iphone apps

[Trocken]

Just got a copy of Master Bender from www.masterbender.com for iPhone
On certain bends the difference can be much like 2"-Have you ever come
up that much short?-doesn't make it to the connector or coupler.
The cosecant method has been around for many years and is just an approximation
but it works well for some bending. But critical bends, or complicated bends
like 3 or 4 pt. saddles or if you are down to your last big piece of 1" or 1 1/4"
conduit the precision radius-of-bend method sounds like the way to go.
This iPhone app sounds like you can save on material waste and labor costs.

I have never missed a conduit bend. I have made a good many pieces for future use, but never been wrong.

We don't do much conduit. Almost never.
But we bend a lot of copper and getting that wrong can be very expensive so that application or one based on it could be quite handy for us.

Some copper bending by my guys:

I recall a college class where this act of bending was presented, I believe it's called "Bend Allowance", and or "Bend Deduction", I'll default to Wikipedia in this cause it seems thorough enough (for speed and convience), but I'm not denying the good old machinest handbook or the I-App...

I needed a good laugh today. I have made my share of "future use" bends too.

I used to tell people that I wanted to make it perfect and that pile there just wasn't perfect enough.:happysad:
