Title: Earl's fittings
Post by: Old phart phred on September 15, 2018, 11:58:19 pm
Stopped at an estate sale today, bought a big box of Earl's fittings and hose. I assumed the braded ss hose was toast as it was setting next to a 91scca rule book. Are the Earl's fittings still current or usable?

Also in the box there appears to be an aircraft oil accumulator. AN fitting on one end of a cylinder, Schrader valve on the other. Cut the safety wires off and took it apart last night, and inside a floating piston. May have to put it in the oil supply line feeding the turbo to spool down on. Guessing $5 well spent.

 The oil accumulator works well and exactly like the water pump  accumulator. All you need a is a vertical tube sealed at the top, plumbed into the turbo line  or oil gallery.  Dash 6 line is about the right size to control the flow both directions. ( if you dont want to use a electric or manual valve.)  It should keep the pressure light off for about 6-10 seconds post shut down.  The dash 6 size is not too large for the oil pump to fill the engine normally  on start up.
 If you use the type with the air fitting on top, use about  50% of your hot idle pressure.  7psi is common. 
 Yes, Turbos like cool down oil.

With multi-engine aircraft, an accumulator is frequently an option with a pressure tank to push the oil into the engine for the props to bring them out of the "feather" position and make restarting the engine much easier. Much tougher for the starter to push the blades into the wind instead of taking advantage of it. They are usually called an "unfeathering accumulator."

lots of aircraft and aerospace stuff floating around town, since we are the air capital of the world.  Used to go to The Yard Store to buy all sorts of aviation fasteners, and other surplus stuff, fill a brown bag and pay by the pound. Probably like an unorganized Aircraft Spruce. Boeing MAC used to have a surplus store also, you could by prepreg fiberglass, Kevlar and carbon fiber that had exceded the "aircraft" expiration date stored in walk-in coolers.
