Thanks Paul. The plan is to dive a bit deeper and introduce some formulas that apply Trigonometry to pipe offsets. Hope you continue reading, there’s also archives going back to January. Be safe AJ.
That would be great! There's more math to come so hoping it doesn't get too boring. I wrote a manual many years ago about applying these techniques to solve some more Advanced Offsets, that is where much of this material comes from. Well it is advanced for a Pipefitter, a Rocket Scientist maybe not.
Well done, A.J. This would make a good primer for a course on machine shaft alignment. Especially for the Reverse Indicator Method.

The takeoff for the 3" 45° fitting is 1 7/8"
The takeoff for the 4" 45° fitting is 2 1/2"
T1 length =T2 length = T3 length = T1 travel - 2 * 3" takeoff = 80 5/8" - 2*1 7/8" = 76 7/8"
T4 length = T4 travel - 2 * 4" takeoff = 80 5/8" - 2*2 1/2" = 75 5/8"
A = A length - 3" takeoff = 26¹/₂” - 1 7/8" = 24 5/8"
B = B length - 3" takeoff = 29” - 1 7/8" = 27 1/8"
C = C length - 4" takeoff = 33 ⅛” - 2 1/2" = 30 5/8"
D = D length - 3" takeoff = 57¹/₂” - 1 7/8" = 55 5/8"
E = E length - 3" takeoff = 55” - 1 7/8" = 53 1/8"
F = F length - 4" takeoff = 50 ⅞” - 2 1/2" = 40 3/8"
Matt looks great, one point and I’m sure it was a typo.
50 ⅞”- 2 ¹/₂”= 48 ⅜” e₂e
Thanks for reading the post. Hope you enjoyed it.

I'm sure I fat fingered my calcumulator. Yes - that was fun. Some time I'll show you how we do that in CAD when we're too lazy to do the math.
