Proof testing new lines

[Geoff Goodworth]

G'day folks

When you make up a new set of lines, who pull tests them and what loads do you use?

Thanks in advance, Geoff

Myself and "old mate" shed wall to hook the lines to Geoff!   The old heavy duty spring scales do the rest to the load which the FAI suggests we use.  Well that's my method for use here in OZ anyway.

I use a digital fish scale.
Pull each line individually.
.012   15#
.015   20#
.018   25#
Slow gradual increase pull up to test #, and hold for ~10 seconds.

I do mine in the yard with a pulley weight tester on a heavy wood stand, which also holds the engine test stand and a sanding table.

I have two weights, 20 pounds and 33 pounds.  With these, I can do one or both lines at a time as the size requires.  The 33 pound is just right for F2D and therefore just about anything that flys on .015 lines.  I can do lines and handle or lines and airplane. Two out of three is not bad.

I don't have a picture of the completed assembly, but these in-process shots should get the point across.  Considering the amount of weight in play, the device can't be all that light.

In the final pitcher, the old stand is acting as a paint stand for it's replacement before scrappage.

ps: Not just new lines, but also used lines after a while.
