Thank you so much for this ! If you could make more conduit bending videos that would be so helpful. Our industrial program in school shows us electrical diagnostics and install but does not teach conduit bending and math layout.
@@norcalsolar8291 The shrink is based on both the degree of bend and the raise. To find the shrink constant for any degree the formula is (1/sin of angle - 1/tangent of angle) for a 22.5 degree bend that is .2 so you would multiply the raise by .2 to calculate your shrink.

If you could make a video on layout And how to space things out evenly that would be amazing
Greatly!!!
Pvc using spring benders?
Is the shrink based on 22-1/2 degrees or the 45 degree shrink per in inch?
The shrink isn't based on the degree of the bend. It's based on the inches of raise.

The shrink is based on the 22-1/2 degree bend. The shrink for a 22.5 is .2 in his example .2x4 is .8 he just used 3/4" for simplicity
Is the shrink 1 1/8
the other video showing a 4 saddle using an anctual bender was way more understandable
Man what do I do if I only have the rise and center mark, this math is easy when you are already given all the measurements
