Ive read posts of people having difficulties putting the curado sideplate back on and spool tension was to blame. I guess if person was to press too hard putting plate back on something could fail/crack/deform. I did just go and try my 50E tightened the ccc a turn. The side plate was more difficult to take off. When going to put back on the twisting lockdown was even more difficult to twist/lock.
I keep the spool tension to a minimum, as should be done, so not an issue for me.
