Vic ! You need to know how much you are inspiring me, 6 month ago I would not get into a built project, know I'm considering building a Hummingbird, please keep doing those very educational video, also thumb up for the lady behind the camera that ask some very good questions
Thanks for the instructions, but I have a couple issues with what I saw. They make a mandrel to place in the rubber hose fitting that keeps the sharp edge from cutting a sliver of rubber when being tightened. Why didn't you use that? I didn't see you look down the inside of the hose to see if it was clear after assembly. And I saw you assemble the teflon hose with lots of metal fragments from cutting it still in the joint. I had an A&P make me a set of rubber oil lines, and there were C shaped slivers of rubber inside the hose. I'm glad I looked down the inside. It was almost fully blocked, and the slivers could dislodge and get stuck in the oil passages. It taught me a good lesson about inspecting work, even by experienced mechanics.
these fittings don’t require the use of a mandrel. My apologies on forgetting to check visually in the video. I always do that. I’ve been making these for years without any problems, and I’m sure thousands more people have been doing it on cars, etc.
This is pretty timely because I am about to order hose for my fuel system. I'm looking at all of the standard speed shops, but not seeing fittings that are stainless. Can you provide a link to the the fitting you used in the video? Is that an earls speed-seal? Looks like the fittings are specific to their hose.
@@baselegaviation1614 Thanks for the reply Vic. I'm actually surprised you haven't seen failures on the 90* fitting shown at @13:34 bolted to an engine (like a fuel line) as the aluminum tube on the end of that isn't all that thick and it for sure has a finite fatigue life.
Vic you should pressure test your custom hoses before installations. Not too much work to create a testing fixture. 😊

That is awesome!
Thanks for sharing your knowledge with us! Your videos rock!
... An excellent well explained video ...

Crush plate on the composite prop? I have a Whirlwind CS prop with composite paddles. Would like to see what the plate looks like. Thanks!

yes, they are Earl’s speed seal fittings. they are aluminum.
