Hi Mike,

Thanks for the information.  I had just been on the new web page
for AEA/Tempo.  I didn't find any reference to the Isoloop.  So I
was afraid that they weren't going to be continuing or supporting
this product.  Its good to know that they can supply the part.

You are correct about the shear pin at least for the earlier
ones.  Of the units that I actually disassembled and looked over
carefully (as opposed to units where I had the owner do this),
one was definitely a failure related to the pin.  It looked to me
as though the pin had been driven into place but I didn't think
much of this at the time.  I thought it might have just been an
artifact of the molding process.

At least one of the other loops was definitely bumped.  It worked
prior to the bump and didn't work after the bump.  So we ascribed
the failure to the bump.  The failure of this part did not seem
to be related to the pin hole.
