Guy Wire System for Spiderbeam Mast with Rope Tensioners / Winders

This Guy wire system for SOTA/POTA is a bit more than just rings for a Spiderbeam 7m mast:

Its winders are also rope tensioners, like those used for tents. This makes trimming the wires easy and fast, exactly what you need on a windy mountain top!

I'd recommend to use the combination of the ring for the lowest element and the short winders/tensioners. If you have a ring for higher elements, you might need some assistance in erecting the mast. The larger winders are needed for a total wire length >2.5m (when you use a 3mm paracord).

The ring has two different inner diameters to allow it to rest on the lower element without the mast being fully erected. If you don't want to use supports for this feature, just use the openSCAD file and enter twice the same diameter.

If you need specific diameters for your mast you can use the OpenSCAD file or write me a comment.

What you need:

• 3mm paracord of your choice in an appropriate length. I'd recommend this formula for the length of each section: [height of ring above ground]*1.75*sqrt(2)
• 3 Tent Pegs

Building instructions:

1. Print a ring of your choice and 3 winders (PC/ASA recommended, Prusament PETG works as well). Use supports for the rings!
2. Cut three paracord to the length of your choice
3. Mount them on the ring. Use a Bowline (https://en.wikipedia.org/wiki/Bowline) (German: Palstek) or something similar useful as knot.
4. Thread the paracord through the winders/tensioners according to the pictures. Use a Bowline/Palstek again!
