How is this any more dangerous then just using a regular chainsaw? You guys are WAY to quick to condemn, not saying there couldn't be a guard here and there but overall this is just as safe if not safer then running a regular chainsaw into small brush like that. "Kick back" with this setup might hit a finger or hand, "kick back" with regular sawing would result in loss of facial tissue. Yes I do cut wood, have for over 30yrs. also own a sawmill, so no I'm not green when it comes to chainsaws nor logging. This design is not all that bad and if it works for him I don't see an issue. No matter how many safety devices are forced onto us through self save laws, there will allways only be one true safety device that'll do the most............operator knowledge. Seems to me this person has made something that makes life easier for them and IMO didn't do all that bad. Okay I'm done with my observation back to all you recliner chair pros.
