Don't throw out your gut G!
The gut core from a used gut G actually makes a really good E string, and it only takes a few moments to make one once you get the process down.
By hanging a weight from the G and cutting the winding at the end, you can easily unravel the whole string in about two minutes just by turning it at the top with your fingers. Obviously, this can destroy the twist of the gut, but the fun part about that is that you can make your own custom twist to make the string stiff or flexible. All you need to do is add oil, turn it, and hang it from someplace with a clamp attached to keep it from untwisting again. Then you leave it for a few hours and it's done!
Better if you make a video showing the process. Would be really great.
Yed please show a video or pictures! Also, do you know approximately how many mm the resulting E string will be?
Depends on the thickness of the G and whether it has a silk wrap underneath, but the resulting string will be about 0.60 to 0.65 mm on average. A fairly heavy string.
Thats way to heavy for an e string, heavy even for an A string.
E string is about .33mm
0.60-0.65mm is a heavy gauge E, according to Gamut: https://shop.gamutmusic.com/violin-gut-e-1/
well i just got gut e string .013 i assume that is inches??
Well evidently my 13 is a pirastro gauge number, not inches
