Basic Procedure for notching

There are two basic methods for notching finished pieces. The method you use will be determined by your particular job.

Measure centerline distance between two existing tubes and record acute angle at both ends.
Mark	Measure
Calculate overall finished length and cut work piece.
Calculate	Cut
Notch one end at calculated start point and mark centerline at other end. Notch other end at calculated start point
Notch	Notch
Ready to Weld!

2) Notching a non straight-line tube between two existing tubes or a notch at one end only "trim cut"

Lay up and secure your piece of tubing that is to be notched on one end only. Mark both centerline and the intersecting point. (position the snap collar locator so that the small center Vee on the collar is on the acute angle side). Record angle with protractor (no need to measure if it is to be a right angle joint)
