As far as the weather goes, we got about 8 inches of snow here, but my parent are in the Michigan snow belt in Decatur (SW) where the lumber is headed in a couple of weeks.
As for the type of maple, it is silver maple, pretty soft and milled nice and easy. I am using the 390 and I don't have any issues. Its not what I would call fast, but the power to weight is perfect for a 65cc saw with the mill attached. I can mill all day and I'm not overly tired at the end. I also make sure that the logs aren't too big. The large maple in the pics is about 22-24 inches and will be the largest I've milled to date. This one will be squared and quartered. The quality of the milled wood is great as far as I have been able to tell, few knots, with some good tight grained darker wood in the center. All of these logs were branches (the trunk was over 40 inches in dia. and solid).
The leftovers are cut, split, and stacked, waiting their turn for the fireplace. After my hand surgery last week, the fiance thought she would bring in some wood for a fire and I said to use the white oak on the pallet next to the shed. Well, she ended up bringing in a load of the freshly cut maple, twice as heavy, and she had to bring it back out to the pile and grab some of the white oak. Oh well, it was truly the thought that counts.
I should be back to milling next weekend, so I am really getting the itch and its only been a week.
