Notching a tube where a centerline distance can be
determined between two existing tubes:" |

Measure centerline distance between two existing
tubes, regardless if they are parallel or divergent
and record the acute angle at both ends A and
B.

Calculate the overall finished length using our
‘EasyNotch’ software. (The software will also calculate
where to start the notch at each end.) Cut the work
piece to exact length as calculated. |

Set notcher to correct angle and notch end ‘A’ at
calculated start point. Flip the tube around and place
the other end into the notcher. Be sure that the tube
is ‘clocked’ correctly. Our handy Snap-Collar locators
can help with this by referencing centerline. Notch end
‘B’ at calculated start point. |

2)
Notching a tube where there is no reference to the other
end: |

a video of this procedure
Lay up and temporarily secure a tube so both centerline
and the point of intersection can be located. It
is important that you position yourself so that you are
viewing from a right angle perspective. Mark these
locations with a felt pen. Using our handy SnapCollar
locators can also be a big help in marking the
intersecting point. They slide into position for
accurate marking and if the tube has to be
rotated for positioning into the notcher these
snap-collars make for an easy reference. Record the
angle using a protractor. |

Use our ‘EasyNotch’ software to calculate where to trim
the tube from beyond the point of intersection. Cut the

Set the notcher angle and clamp the tube in place
positioned correctly. Centerline mark should be at the
very top (or bottom in some cases), which is 90º to the
center of the holesaw. And the edge of the holesaw
should be in line with the intersection mark. Slide or
remove the snap-collar out of harm’s way and make the
notch. |
