One of the saws I run is a Dolmar 510. I have really noticed the improvements that antivibration features make in newer saws. My older saws have poor or next to none. I got the 510 with a 18 inch bar and 3/8 .050 chain. The two saw dogs and the Dolmar 64 link chains for this 18 inch bar nearly make this equivalent to a 16 inch actual cut. I put a 20 inch Oregon bar on it to get the depth of cut I needed in cutting up some 32 to 36 inch diameter cottonwoods. When I got the saw I was not aware that the 18 inch Dolmar bar only took a 64 link chain. The saw runs great and cuts through the cottonwoods with the 20 inch bar easily. Has been a pleasure to run. I don't think I will ever notice the additional weight of the aluminum case over the lighter mag case of the 5105, but then I don't cut for a living. Maybe I just enjoy seeing the chips fly so fast and furious that the extra pound isn't a distraction for me.
