Hi Folks,
I have a Ripsaw, powered by an 044.
Cuts a good bit of wood for not too much fuel, and fairly fast.
Saw and powerhead weigh about 45#, can be carried in prety much anywhere.
I think this is it's forte, being able to cut a log or two where you can't get a WoodMizer to the log, or easily extract and transport a log to a mill.
I have very good results cutting Pine, Poplar and other softer woods.
It will cut wood like White Oak, but, as noted by J123, it doesn't take much to knock it off course - a nail or knot can bump the cut up or down and you are no longer getting a flat cut.
I too built an easy on/off weight for the side opposite the motor.
Blade tension can be an issue, as the lightweight frame can't pull the blade hard enough for optimal blade beam strength in hard woods. Gotta use a sharp blade and slower feed rate.
I'm pretty sure there was a larger version with bigger capacities that could run on rails at the sides of the log. Still pretty portable.
Thanks and good health, Weogo
