Dgmultimedia and Rik,
I am sorry to have put you both to some trouble on this issue. I explained my self very badly.
Let me start this again, please.
When I first heard about Flemish twist strings many years ago, I looked at some pictures and immediately "saw" rope splicing. It looked like that to me.
Ever since then, I have imagined the loops to be spliced like a rope. I know that splicing is quite tricky, so thought nothing more about it until some recent threads on here. Then I watched a video and saw how the twisting was simpler than the splicing I had seen.
At the time, as I watched, I wondered if the person in the video was showing a simple version and I imagined that the twisting would be no where near as strong as splicing. That took me on to guessing that perhaps it was OK to twist for light weight longbows, but no good at all for warbows or similar.
So really, my concern is, how strong is the twisting method? I know Rik had a problem first time; but that resulted ( I think) from not twisting the strands before crossing them over next. Is the finished string's strength dependent on that twisting before the crossing over; in the sense that too little and it doesn't work; or even too much is bad, too?
