Why isn't there a start mark arrow on a triple nickel like you have on a hand bender?

Does it matter? You can change the deduction to make the start point where you want. I might use the front of a hand bender for a 90 because it's easier to see (I always use it for offsets) the mark on the raceway. Just take the standard deduction and subtract the distance between the bender mark and the front of the bender. That number will be your new deduction for the front of the bender.

The place on the bender where you line up put the mark on the raceway is arbitrary. You can build a bender and make the line up mark anywhere you want. You would just need to adjust the deduction based on where you decide to have the line up point.
Yes I figured it out it was a little confusing at first but yeah you can use the arrow as a benchmark or the front of a shoe as a benchmark the arrow on a hand Bender is start of bend
Thank you for everyone's help!

Exactly. Say that you decided to build your own 1" bender because you wanted a larger radius bend. You build it then you bend your first piece of conduit by starting the end of the pipe even with the end of the bender. You end up with a 15" elbow. That will be your deduction for elbows when aligning the mark on the pipe with the end of the bender. Now you decide that you want to use the arrow that you marked on the bender 3" back from the front edge. When bending using you arrow your deduction for an elbow is now 18" (15+3).
In the end the deduction and starting point don't really matter as long as you've compensated your deduction for where you align the mark in the bender.
