Much like Japanese 4-1, 6-1 is a simple weave but provides greater strength and protection than Japanese 4-1. The method is slightly different because Japanese 6-1 does not form square-shaped patterns.
Step 1Row 1
When making a Japanese weave, two different ring sizes are used; the larger rings are connected together by the smaller rings. To start Japanese 6-1, Take as many of the large rings as you want and connect them to each other in a long strip with the smaller rings. The pattern should be: one large ring, one small ring, one large ring, one small ring, etc. See picture below for clarity on this step.
native japanese gusari (maille) was never riveted. mainly because the flat or horizontal links were never larger then 16awg x 1/4in and the cross links were never never coiled from larger wire then 16awg. nanaban guasri or foreign maille was introduced from europe in the end of the momoyama period (c16th centrury) and this *was* sometimes riveted. then again, nanaban gusari is nothing but e4-1 hanging the wrong way.
to make so gusari (j4-1) stronger, they just used key ring style links which was named seiro gusari. of course *that* particular weave was woven in the style of so gusari. asa no ha gusari (j6-1) was more rare then that because it took so long to weave and was mostly used in the kote or amoured sleeves and would have hex plates built in to increase the impact resistance of the weave. the worth company sells some oval split rings that are *perfect* for seiro gusari or a seiro/asa no ha gusari hybrid and they're only $23.40/thousand for the size you'd need.
hope this helps! -bows-
i made a pair of kote once using mild steel 14.5g 1/4 in for the horizontal links and mild steel 16g 3/16 for the connectors with 12 mild steel 18g square square plates woven into the upper arm and 3 mild steel 18g plates for the forearm. it in itself was pretty heavy but it was nice and durable. then again i had actual intentions of using it as armour in case of a knife attack. i was a bit paranoid back then. lol
Sorry I have an almost scary sense of pattern recognition. I spot almost everything out of place.
