[NSRCA-discussion] OS160FX/Perry Oscillator pump

[Mark Hunt]

Jack,

Yes, you will have to order the OS140 pressure nipple (I found it under 
replacement parts on Tower Hobbies website).  One of the top backplate 
screws (can't remember which one) can be drilled out (dont drill out the 
threads) to access the inside of the case.  Replace this screw with your 
fitting and your should be all set for pressure.

I used a small brass tube as a drill guide to protect the threads.  I also 
held the case upside down while drilling to get most of the shavings to come 
out during the process.  You will have to carefully remove any residual 
drill shavings.


good luck,
mark
