I`d got the parcel in the post yesterday and assembled the components. I thought that I had tightened all bolts and nuts enough but I realized today that I had not. There is tremendous vibration once the mill is in action and one side of the saw bar moved within the bracket towards the chain while cutting but I saw it in time and there was no damage done. Also the little wing bolts on the push bar came loose and a nut for the grip/handle fell off. I rearranged and tightened everything and could continue sawing with no more hiccups. This mill is almost a true copy of a Granberg at a fraction of the price. The holes in the aluminium brackets were not large enough to receive the bolts, I had to widen them with an 8mm bit, also the setting of the cutting height is tricky when you want to tighten up. I already ordered 4 Hex Rod Coupling Long Nuts 30mm for easier access . If you're not prepared to put in a bit of extra time, this may not suit you but I did and I am quite happy with what I have now. If you set things up carefully the mill will also be quite accurate. Best thing really is that I don`t have to haul the logs to a mill. Cut a tree and mill boards or planks there and then. It`s great...
