Why you should use the right socket. Replacing the drum on the Forest Master FM6DD-MUL.

A step by step video on replacing the drum that holds the blades on a Forest Master Chipper/ Mulcher. take this video as a reminder to use the right socket when undoing a tough bolt. forest master actually sell the perfect socket.
I stupidly rounded the bolt that holds the blades. I went down the route of drilling the rounded bolt out and that went badly, ending up in me ruining the internal thread of the drum that hold the blade bolts.
This left me with a chipper that i felt unsafe using.
Even though the bolt screwed in quite well, i decided to spend the £50 and get a replacement drum (part 15).
