Allegedly the Aerobat oil breather goes a long way to eliminating that oily smear on the belly of the plane. A standard breather elbow is ~$15, and the Aerobat is anywhere from $190 to $500.
The only difference is a 2.75" tube brazed to the std brass fitting.
Has anyone found a source for a more inexpensive solution, or have you made your own? According to things I've found on the web, it can be done by either brazing or silver soldering the tube to the fitting.
I just can't see paying more than $20 for such a simple contraption. Ok; I might go $30...
Carl...funny because I ordered the brass tube and solder from McMaster Carr today. My fitting has an ID slightly more than 1/2" and I ordered .50" OD brass with a .063 wall. I'll let you know how it comes out.
I tried many different sources for the part but as you found...ridiculously expensive for what it is.
...and it came to $20.98 so your first quote was right on:)
You might start a side business making these up!
Very nice! David did you make yours 2 3/4" from the end of the fitting? Looking at the solder I ordered from McMaster carr, it does have some silver but not enough to make it what I believe is considered "silver solder". I was going to try a brazing rod???? I know the whole idea is to have a higher melting point...regular solder being around 400 degrees and silver solder and/or brazing road above 1100 degrees (I think).
I'm noticing your baffles there...really nice job around the prop hub...the Zenith baffle kit does not include those parts...did you fabricate those yourself?
Yeah; saw that the other day. $190. A bit steep for what u get.
Thanks to Don, for identifying a source for the tube, I’ll prolly make my own. Since I already have silver solder, it’ll be even less!
I assume my A-65 would also benefit from this modification? And would the dimensions be identical? I have a machinist friend that could help.
Roger, I'm not sure if the A65 engine case is smaller or the same size as the O200. You could probably check that out easily enough. At a minimum even if you had to shorten the tube somewhat it should also be a benefit on your engine.
