A little fiddly to build but once you've dont it, what a great product!
I was a bit worried about the size of chainsaw it would hold but I have a large Stihl 290 and it held it in place no problem. I dont find it difficult to mount the saw, you just need ot make sure the clamp is facing down and ensure the chain runs clear of the mount and the safety guard.
And boy, what a fantastic logging aid it is! I buy my firewood in chord length and my workrate has gone up six-fold with this, compared to a standard saw horse.It feels safe and solid and my osteopath is delighted! I can totally recommend it.
