HVAC/R Pipe Sizer

3 (so far) simple pipe sizers for anyone in the hvac/r trade like myself.

Agreed that most of the time you can look at the pipe and eyeball the size OR find the pipe clamps but if your with an apprentice or a new engineer who may not be able to eyeball it, you can chuck this to them and you know the size is right.

I will be adding more but for the time being i have done ¼" upto 1 7/8"

v1 = 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1"
v2 = 1 1/8", 1 1/4", 1 3/8", 1 1/2"
v3 = 1 5/8", 1 3/4", 1 7/8"
