So I came up with this idea a couple nights ago and I thought I'd share and maybe get some help to make it better.
-The top one is just a 1/2" PVC tube cut on opposite 45 degree angles. Wrap the line around and I used a hair tie to secure the line.
-Middle piece is same, but with cable. This was actually the first one I cut and the cable coincidentally was the perfect length to just hook the loop on the shaft pin.
-The bottom piece is more of a final product, but requires more work. It has an integrated cap for the speartip and I wanted to make the tube longer to minimize the amount of turns on the line. The inside 45 degree cuts is for the last bit of line and is just far enough apart to be able to stretch a hair tie over the line to keep it from unraveling.
The design isn't perfect. The cuts are good, but I'd like to get ideas on securing the last bit of line. The hair tie (or rubber band) would work, but I was hoping to just tuck the line on itself, but it doesn't stay. Don't use the thin 1/2" PVC like above, it's too weak, there's a thicker one (SCH 40, I think). If I bang the bottom piece against something, it will break at the weak points.
So, I'd like to develop something SIMPLE and very EASY to make. Maybe this is good enough and I thought you guys would like it. It cost a total of $2.68, and I have a lot more PVC and caps to make more.
