You can speak Mr Parker... I know you've gone back to blue
BTW, if any one is interested, the parts required for a spool for the 416 at the moment....
TAM3454401 Direct Holder (TRF415 MSX MRE Aluminium spool)
TAM9804268 Direct Cup (TRF415 MSX MRE Delrin outdrive)
TAM9804267 Direct Coupling (TRF415 MSX MRE outdrive sleeve)
TAM53500 2x9.8mm pins (2 required)
Also, not required, but useful if you like to quick change...
TAM54203 37t One-way pulley
TAM51278 K-Parts (has the bearing holders on)
Then mount the drive pulley to the other side of the spool, and ream out the 416 bearing holders for clearence of the sleeve. Pictures here...
