Time to start tubing runs. Plans say do the vent and fuel lines first then you can take off the wings. The vent lines have these fittings that go out the bottom of the forward fuselage. The threads are scrapped off and the tip is cut at a 45 degree angle.
I put them in my drill press and filed off the threads.
I made the 45 degree angle on the belt sander. Trying to saw it was way harder than just sanding it down to 45 degrees. I guess I'll have to find a screen to glue onto the holes, per drawing.
