Hello, YellowHelmet,
Long, old (2013) Severn video on boom regripping:
A different, shorter version found by Googling Boom Regripping, from 2022 :
www.google.com/search?client=firefox-b-e&q=severne+boom+regripping&sei=pjG2aubDO6anvr0Poe6P6As#fpstate=ive&vld=cid:26acbdde,vid:sh4u4p-zKzU,st:0The links worked for me as I was preparing this reply, so I hope they work for you.
Hope this helps.
