You said you shortened RM spokes about an inch? How did you re-thread them? Cut or thread roller?
i know you know this fact pj but others that may not know that for a given rod or round stock diameter a rolled thread finishes up oversize as you know but an interesting process where the stock is simply deformed or fomed into a thread without removing any metal
so a cut thread on a spoke will be crazy loose in the same nipple cause it is cut into the stock all of the thread profile actually below original diametrer
wheew wel im glad i knew that besides the rolled thread is tougher being worked and it can keep going into a nipple till it comes ot the end
i bought the tool new 75 bucks 2 years ago finally used it in anger
i tried just gripping the hex in the 3 jaw nope it has a hollow body and a screw set
i used a worn out fox factory shock shaft the roller head wants to be floaty not secured tight
'the screw set went into the shaft ports already made and hollow just had to od turn it a bit
now i had never rolled a thread ive done knurling and the last thing i wanted was to get 22 spokes done then have all the smoke escape from the threader (overheat it)
so i used some good oil 30wt with some moly in it black stuff but then i could not see my sharpie mark but i kept it dripping wet the wshole time on not so much backing out
after 4-5 spokes with too long a thread i made the very complicated depth indicator poly hose dealy as as shown
i played around with spindle rpm and settled in at 418 rpm and went thru 6 spokes and i was brushing on lotys of oilgraph but not doing cool9ng like flowing coolant would
after six she hot but not dangerous hot
then go double check the nipple fit run nipple on-off with drill motor mostly cleaning dry mud out of threasds
hey pj yeah i got dumb lucky on that deal i wanted the al nips many were frozen and worse bcause of the tensioin
so i kew i would need about 1'' shorter spokes going down to 19 from 21 so i cut them about 1/4 - 3/8 from nip which is pretty much muinus 1 ''
this allowed a good grip on stub spoke and by god taking off the tension was the main deal it was trying to take wheel apart by threads
there was no more frozen ;D
