I have been making skinny strings [6 strand] for about 4 years now. I pad the loops to make them 12 strand. These are flemish twist strings. I started out making them with D-97 and now make them with Astro-Flight. The problem I can't seem to resolve is stretching. I thought that after a week of shooting there would be no more stretch with these materials. That has not been the case. They seem to stretch forever. They don't fail so I can't figure out where the extra length is coming from. Thoughts.....

I'm no flemish string maker, but the D10 skinny strings I'm using now don't move a bit after I burnish in the wax and 20 or 30 shots.
They're not stretching. They're growing. LOL!!!
That's why they don't fail.
On a serious note, I don't think a 12 strand string is considered a "skinny string" unless it's for a 150 pound bow.

What weight are you shooting, sir?
I have made 8 and 10 in Astro Flight, no complaints, yet. Also, what are you using in the padding, dacron or the Astro Flight? How much twists in the string?
I have used 8-10 strand Astro Flight built by Steve above.I have not had any problems with stretch once the string settles in.
I do burnish the strings as well with some wax and a small piece of leather immediatly upon stringing them up.After shooting it and keepping the bow strung for a few days it has settled in for me.
Switch to Ultra-Cam.
The strings are 6 strands between the loops. I pad the loops with 6 more strands of what ever string material I'm using. What I mean is that I have to keep adding twists to maintain brace height for the life of the string.

I would make 2 more strings in 8 and 10 strand and see what happens.I think the Astroflight in 8 or 10 would be better.I have not tried 6 strands in Astroflight.But have tried 8,10 and 12 and was very satisfied and had no issues.
I would go ahead and burnish that 6 strand and see if that does not help you out.wax it well and go up and down the string fast to build up some friction and heat with a piece of leather about 3 by 3 inches.
Hi Michael,I have some D97 that stretch forever and some D10 that don't move also if you cry.
If you want a 6 strand string then changing to 8 or 10 will be of no use to you. Ultra Cam will not creep after it settles in and it doesn't move much or at all then depending on the bow poundage. I use 6 strands of UC for 55# and under and 8 up to 65# with no problems.
Michael, you didn't answer my question on the weight, or the twists.
Fellas, I make Ultra Cam strings for a well known bowyer, and have made the Astro Flights also in the strands mentioned. Never seen this much creep in either.
D-10 and Astro Flight are one in the same, just different companies. No one has the Magic Material!
My experience has been the same, 6 strands of D97 creeps daily and Ultra stays put. For my 50# bows I use 6 strands of UC and loops padded to 14. SBD builds a string to those specs and does a great job.
i've spun up 4 and 6 strand padded loop endless strings of dynaflight'97 and f8125 with no stretch/creep at all.
Frank: Pardon me I wasn't paying as much attention as I should have. I mostly shoot bows that draw between 58# and 62#. I use the old 10x draw weight formula for string size. The Atro-Flight breaks at 125 so I figure 6 is enough. I normally put in no more than 10 to 15 twists before I put it on the bow. The string I just made is a good example. It'
s for my 70" 21st century I made it 66 1/2" twisted it to 66", put it on the bow and had my 6 1/2 brace when I started to serve it. When I had finished I was at 5 3/4". I made it Monday of this week. This AM as I write this I added twists to bring it to 6 5/8" before I shot. It now measures 6 1/4". I had assumed that I was doing something wrong but I guess it is what it is.

frank bullitt has made a half dozen or so astro flight strings for me and i don't think i've had 1/32 of an inch stretch in all six strings combined.
