​Guidelines

• Replacement line is free for currently paid RMHPA members and is not to be shared with non-members.

• Take what you need to fix a broken line, plus a spare for the next one.

• If you're heading on a long trip, take a couple sections of various sizes to have a small repair set with you.

• This is intended to supply an occasional repair - a couple meters per year at most.

​

How to get line

• Telegram one of the volunteer coordinators below to help you out. Offer to meet them at a launch or to swing by their house and pick it up.

  • Boulder: ​Benjamin Buren

  • Golden: Josh Taylor

  • Silverthorne: Charlie Martin

• Look up your line sizes in your manual and know what size and length you need ahead of time. Bring a sample of the broken line to compare.​

• Line we stock (Liros DC and PPSL)

  • DC40: 0.5mm, top brake cascades on most wings

  • DC100: 0.8mm, some A/B wing brake cascades, A/B/C/D wing small intermediate lines

  • DC200: 1.6mm, large intermediate lines, lower "b" and "c" cascade lines

  • DC500: 2.05mm, primary "a" lines for all gliders

  • PPSL200: 1.42mm, SHEATHED brake toggle lines, plus some lower lines on A/B wings.

Tips

• You need a special blunt needle to make the splice. We'll give you one for free with the line if you need it!

• Watch some videos of various ways to make the repair.​

• Optional: if you want to stitch your finished splice (not always needed, but that's the pro solution), we can also give you the correct thread (and bobbin) to do that with your sewing machine.

  • Use bonded polyester thread that is UV stabilized so it won't degrade. 

  • Thread size 46 for small stuff with a needle of 90/14 to 100/16.

  • Thread size 69 for bigger stuff with a needle of 100/16 to 100/18. Some home machines might struggle with this thread.

  • To make brake line loops, dial in the zig-zag length and spacing on a piece of paper first, then use a jig to hold sheathed lines in place and in a loop when sewing. Carl Marvin has little jigs that hold the line in place.

  • When sewing the loop, use the same loop length, stitch length, and backstitching pattern as used on factory lines on your glider.
