Bubble Flare

Had a tool to do that in the aircraft maintenance shop, but it's been a few years and I don't remember what it's called! Kind of like a tubing cutter in reverse. Outside set of rollers with a center groove, little roller that went inside the tube and pushed out the bead.

"Tubing beader"??

Any A&P mechanics here that know the proper name?

Actually, I am a A&P mechanic. :-) I now remember that tool. Been 40 years since I've seen one.

"Tubing beader" is it. THANKS!! First hit on Google, turned up a neat tool.

Thanks again, gary

If you want to cheat, and its OK to have the bubble at the very end, you can use a standard brake-flare tool and only do the 1st operation (the one that creates the bubble).

PS you can also use this method to create bubble flares with a standard brake-flare tool. After you make the bubble, you run the cone down just a skosh to flatten the 1st part of the bubble (the part closest to the end).

According to Gary A. Gorgen :

So -- try a double flare tool, and don't complete the plunge. That might do it.

I don't know what the other followups may say, as they appear to not be visible on the news server which I am using.

Good Luck, DoN.
