I have a mid 70's K-hunter. B-50 string.
The brace height is constantly changing I've shot this string enough that it should not be stretching.
Here's the scenario: string the bow, set the brace, shoot the bow, arrow flight gets funky, brace is 1/4" low, twist string back to desired brace and shoot some more. Now usually the brace will stop changing at this point for maybe a day if I leave the bow strung. If I leave it strung for several days and shoot each day I will have to keep twisting the string to maintain brace. If I unstring the bow overnight, the brace will be way too high the next day, about 1/2" to 3/4" too much, about the same amount of brace that I was losing by shooting it.
Is it possible that the bow is taking a set and not the string? Then the bow relaxes overnight? Maybe this old bow should just be retired and shot for fun occasionally?
Thanks,
Brian
It takes 200 to 300 shots to shoot in a new string. Leave it strung for a month - it will not harm the bow and will help stretch the string in; especially if you shoot it every day.
I have bows that age that have been strung two years and have not lost draw weight or "taken a set". In fact, all I hunt with anymore are recurve bows that age or older.
B-50 will stretch quite a bit, it will stop though. Leave it strung like mentioned above,I read somewhere that Ken Beck left a bow strung on his office wall for 10 years and checked the poundage and it didn't change at all.
Remember.....b-50 was considered a pretty radical step up from the linen strings of yesteryear...
Thanks for the feedback! I love tradgang! I guess I'll leave it strung for a while.

Brian
Semi-related.
In 1959 a man named Everett Pearson made a fiberglass boat designed by Carl Alberg. That boat - hull #1 - has been on the lake I keep my sailboat on for many years. Just changed hands a few years ago and got all new wire cables (standing rigging). As far as anyone can tell there is no hull degradation and it may go on indefinately.
Fiberglass may not have an end of usefull life.
My favorite bow - a Browning Explorer - was made in 1966 and still is my best shooter for a hunting bow. I have a 1965 Wing Presentation-II that is more accurate but has white limbs so it stays on target ranges.
Maybe you need a string w/ more strands in it?
