[TheForge] How to mount this lightweight blower?

I have a Champion "rivet forge" blower, which has a cast-iron gearbox and a
pressed steel housing.  Most other such blowers I've see have some specific
means of mounting to the forge and/or tuyere.  This one apparently had only
the nozzle, which must have been clamped into the tuyere somehow.

I need to mount this blower on a forge, and I would already need to adapt
the small nozzle (about 2" ID) to the 3" ID air pipe I plan to use, so I
might as well use that as part of the mounting bracket.  It should be easy
enough to fabricate a nozzle adapter that also clamps onto the nozzle.

However, I'm dubious about mounting the little blower ONLY by the nozzle.
The nozzle is about 10" from the shaft of the crank along the axis of the
nozzle, and (if memory serves) about 5" from the base of the crank
crosswise to that axis (i.e., parallel to the crank axle).  That's a heck
of a lot of torque that that nozzle-mount would have to deal with!

The only features of the blower that would be amenable for use as mounting
provisions are the five short 1/4" bolts that hold the two halves of the
fan housing together.  What I'm thinking is to "extend" at least three of
these bolts laterally far enough to connect with some sort of bracket.
This would be fairly easy to do on the intake side of the fan housing, but
I'd rather put such a bracket between the fan housing and the gearbox,
which also seems feasible.

Between the fan-housing-bolts and the nozzle, I can see any number of ways
of effecting such a mounting bracket -- that's not the trouble.  The
trouble is just that I really don't want to re-invent the wheel.  I would
really like to see pictures of how this blower was mounted originally, and
I haven't been able to find any.  If anyone can help me find one, I'd
appreciate it.  A Google image search turned up nothing on two or three
goes.
