That is pretty slick, I like much better than the fishing reel thing everyone suggests I use to rewind a throwline. I also hate stuffing throwline. I use a big food container with a lid. It was great when I got it, but plastic breaks with age. Storage is a problem in the truck along with all the other junk I think I have to carry around with me to do a job.
This idea looks good to me as I am rethinking of ways to store throwline and at the same time save space. TM 's thing looks like it has a big enough diameter as to not cause backlashes in the line and would spool off the reel smoothly when throwing and be able to wind the line up quick when done with it.
One of the guys in our Ill. Arborist Chapter who is a contender in the state climbing competion has something that funtions similar but isn't the same if you know what I mean. If you have ever been to a Mexican restarant and ordered tacos that come in a container with a lid to keep them hot is what he uses. Almost the same diameter as TM 's winder but instead of winding the line he spools the line around the inside of the container, then he just put the lid on and stowed it in his duffle bag he uses for climbing. Works for him as I watched put his gear away after the Masters Challenge, his method looked to be quick and easy. I don't know what line he was using and I am sure the line had a memory to it as it just looked a little too easy.
I like TM's winder, can you buy this somewhere? I am not into kiting. I could make something that is similar but I have other things to do. Just easier to go out and buy something to save time and some fooling around.
