[PSUBS-MAILIST] MK 101 Kort Nozzle Assembly

[hank pronk]

Joe,
I would make the hub from one piece of material instead of two.  Then have the tightening method the same as you have now but on one side only.  Less time to fabricate also.

Hi Joe,
If I'm seeing it right, it looks like the struts are an integral part of the 2 piece retainer clamp,
so you would have to attach the retainer clamp & struts to the motor first & then bolt
the kort nozzle to the struts. This would be impossible as you have slots in the kort nozzle
that the struts fit in to.
Maybe you could use the motor stem that the wiring comes out of as a locking point (as I did)
and you could make the unit one piece & slide it on.

Hank, 
  
I'm relying on 4 equally torqued bolts. What other method would you suggest, Im open here? 
  
I couldn't figure out how to guarantee a firm grip on the motor housing otherwise.

Hi Joe, 
Nice job, but I see a problem.  The mounting hub looks like it has a gap on both sides of the two hub pieces.  If those two pieces (hub) do not come in full contact on both sides, it will distort the nozzle.
