Kimono/Pearsall coordinated numbers

[Terrestrial12]

I agree gossamer is roughly 6/0. So would the Belding silk be bigger or smaller. Idk how how 0.17768mm compares without knowing what pearsalls or anything else measures

Hey guys. While looking around trying to find a source to buy kimono silk (other than superior threads) I came across some info that might be helpful. I always ask and hear people always ask "how does it compare to pearsalls"? And the answer is "well it's a little smaller, around 8/0". Well I saw kimono works out to 124 denier. So hope it's helpful and just thought Id share.

Anybody have any experience with Belding Corticelli silks? Or how size "A" is in comparison to pearsalls or any other related ought or denier?

From cane rod builders here's a chart of how many wraps it takes to cover a given length with Pearsall's Gossamer and Naples in the mix. Remembering wrapping a rod doesn't include twisting the thread and that Kimono is a 2-strand whereas Pearsall's was 3-strand. The 2-strand types appear to obdurate{flatten out} quite a bit more than the 3-strand when not twisted. I've wrapped Kimono next to YLI in the 100wt version and get +/- 1 wrap per 100. When twisted I've found Kimono the same, or slightly smaller, than Pearsall's for diameter. Definitely stronger and without the annoying breaks/knots Gossamer has.

Chart has a misprint with the Janome being 72 not 7 as shown.

I heard that Persall's was going to stop making the silk, which is a shame. I do have some still, and I am glad to know there are alternatives. Using a huge bobbin to tye small flies with though, does not sound good.

Kelly, Pearsall's went out of business several years ago. Hence, all the questions about finding a suitable replacement. If you have a good supply of the more common colors of Pearsall's, you might want to see what they are selling for on e-bay.

I looked, and yes it was surprising alright. I stopped using Ebay years ago. I could just save my spools once I get done with them, and rewind new thread on them. That is a shame though, as I used a lot lot it in the past. Now for using on fly rods, the bigger bobbin would not be an issue as much. I did glance through some of the alternatives and it is good to know. Some of you have come up with some good ideas on that, so thank you!

The sewing people have little machines for transferring thread between different sized spools.

They are pretty cheap as I recall.

I had my wife transfer a bunch with her sewing machine, when she still sewed.

a tapered metal pin to fit into the bobbins and a plumbing washer drilled to fit enabled me to spin up the silk with my variable speed drill...
