Dynaflight 97 conundrum.

TomMcDonald · June 02, 2018, 08:01:28 AM

Hi crew.
Hoping someone can relate.
Recently bought a roll of d97 in black and have made a few strings using black and a mixture of other colours.
The black appears to be significantly smaller in diameter than the red, yellow and purple and isn't blending well, i.e. it sits on top of the other colours and doesn't bed nicely. Resulting strings aren't round but bumpy.
Been making strings for 10 years and never come across this issue before.
Thanks for any info in advance.
Tom.

My wife makes all our strings they are D97 and she complains about some colors are thicker than others . White probably the thickest but she doesn't have any trouble with blending different colors .

Different colors are different diameters because of the dye. You can try wiping the strings with alcohol after cutting to remove some of the dye. I believe this will help with your problem.

They aren't dyed I believe but coatings. Florescent being the thickest for the most part. Wax content can vary as well even in the same colors.

If there is as big a difference as Tom is seeing, it could be a miss marked spool. Doesn't happen often but it can. BCY service is great. Get a hold Chad Weaver and he will see you are taken care of.

Steve B is correct. The color is actually a baked on coating, as the fiber won't accept dye well enough to get good color.

White is the thinnest strand, because it has no coating--it's the natural color. Black is next, because it takes very little to coating to get black.

Fluorescent colors are usually the thickest, because it takes a thicker coating to get those bright, vibrant colors.

This isn't specific to just Dynaflight '97. All the materials go through the same color process.

A simple fix is to add a strand to the thinner bundle, and/or drop a strand from the thicker bundle. It won't hurt the integrity of the string.

If there's a significant difference in the strand size, you may well have gotten a mis-marked spool. BCY covers 85-90% of the market...a LOT of material is processed every day, so although rare, it does happen. If you think that could be the case, send me your mailing address and I'll get you taken care of.

Thank you all.

I can show you one strand of d97 in white and it will visibly be thicker than others so white is not the thinnest .

SteveB · June 02, 2018, 08:18:32 PM

I believe Tim it may be the white has no wax making it "fluffier" and appearing thicker. For me at least waxing a white bundle shrinks the dia.

LBR · June 02, 2018, 08:48:57 PM

Steve is correct. It may appear thicker, but it's not. White is how they all start out. Cooking on the coating can only add diameter. That's the case with every material. White/natural will always be the thinnest.

Tim Finley · June 03, 2018, 11:04:35 AM

I just checked it I have 12 different colors of d97 the white is thicker with wax, next thickest is the neon green (or bright green) all the others seem to be about the same . My wife Carol has made over 4000 strings more with d97 than anything else and when her fingers say its thicker, it is .

scrub-buster · June 03, 2018, 12:26:08 PM

Could it be that the white holds more wax than other colors since they are coated with the color? The white would feel thicker because of the extra wax.

LBR · June 03, 2018, 01:22:02 PM

There are always exceptions I reckon. If it's thicker, most likely it's not Dynaflight '97. Does it have any off-white tint to it?

All the Dynaflight '97 starts out as white/natural. The colors have a coating cooked on, which can only add. I'll be happy to replace that spool, but really would like to see it to find out what's going on with it.

Send me your mailing address to chad@recurves.com and I'll get it taken care of.

I need to check, but it may make sense to vary the strand count and use more of the black, and white than the thicker colors? Example: a 3 color, 16 strand string might be 7 white, 5 black and 4 color based on perceived thickness.

McDave · June 03, 2018, 01:34:58 PM

I have the same problem with BCY10, and avoid unequal length bundles by blending the colors. For example, if I'm making a 12 strand string with two bundles of 6 strands each, and the colors are going to be brown and yellow, I will put 3 strands of brown and three strands of yellow in each bundle. The finished string has a blended look which some like and some don't, but I never have unequal length bundles now. I don't mind the blended look, so I routinely make all my strings this way now.

LBR · June 03, 2018, 01:36:01 PM

There's not that much variance even from thickest to thinnest in the same material.

I'm thinking the white is a mis-labeled spool of either 450+ or D-10/Force 10. D-10 is a tiny bit thicker, but normally not enough to matter.

TomMcDonald · June 03, 2018, 07:33:14 PM

Thanks for all the help guys.
And thanks to Chad for offering to help.
Tom.

We've figured out that Tom got BCY-X by mistake. It happens. Going to get it taken care of ASAP.

I've noticed the same thing with fast flight plus. Right now, I have two spools of black. One is thicker then the other. Five strands of one equal six strands of the other. I just make the adjustment when building a string. Some are twelve strand strings and some are eleven. All the same results in the end.

My material was definitely different in a number of ways, not just strand thickness.
