Ken, how are you notching your tubing?

This Jancy tube notcher is real expensive I think.

____________________________________________________________________________
Notch any angle 0° to 60° in any pipe
or tube (round or square) from 3/4" to 3" diameter in seconds to a
gap free fit ready for welding or assembly.

The AL100 is ideal machine for production or short job runs,
eliminating the time consuming and costly process of fitting and
finishing pipe and tube joints.

Using today's abrasive grinding belt technology the ALl00 is a safe,
cost effective alternative to using costly dies hole saws, end mills,
grinding wheels aud flame cutting torches to fit pipe and tube joints.

I am leaning towards an angle vice and hole saw in the drill press.

I.  The problem with fitting tubing for engine mounts is the
extremely high angle that the many of the tubes intersect,sometimes
approaching 165º. and the fact that (at least in the case of the
Tailwind and the RV--(gear leg receivers)) the intersections are
often compound angles.  It is nearly impossible to actually set up to
cut these angles--I have wasted  a very large amount of effort and
time and "ingenuity" (can you use that word if you don't succeed?)

Even if you do set up properly, the high angles produce long
feathered edges which the cutter (hole saw or mill) will grab and
destroy.  Take it from a sufferer who has been there. In the
meantime, with a little practice you can cut adequate notches on a
grinding wheel  in a few minutes.  I supply both gear mounts and
complete engine mounts for the Tailwind.  When I am cutting tubing, I
position the grinder just a few steps away from my fixture.  Even the
most twisted, compound angled nightmare of a saddle can be achieved
in ten minutes.  Jerry Hey
