What size lumber mill attachment do I need?
How big are your trees? How wide of a board do you want to cut? These are questions we can help you answer. Granberg's Alaskan Mark III Chainsaw Mill comes in five normally stocked sizes; 24, 30, 36, 48 and 56 inches long and all of them will clamp on any size chain saw bar(except one shorter than 5 inches and some narrow bars).
We recommend large displacement saws for more effective ripping. However smaller saws will work but are less efficient and some of the bars on the smaller saws are too narrow to mount the chainsaw mill's clamping brackets, without pinching your chainsaw bar's rails.
How much power must my chain saw have?
The general rule is, the more power your saw engine has, the faster the cutting speed. Almost any engine that runs, will cut, it just depends on how much time you want to spend milling your lumber. - How do I make first my first cut?
With the Alaskan Mark III Chainsaw Mill Attachment, you need to have a flat surface for the mill to ride on to get a flat even cut. You can nail a 2x10 to the top of the log or you can buy our Slabbing Rail Bracket Set
How long are your Slabbing Rail Brackets?
Our Slabbing Rail Brackets are about 15 inches long and there are two of them in the set. They attach to two 2x4's that you purchase locally. Attached with the hardware provided, the two rails provide a flat surface to guide your first cut with the Alaskan Mark III Chainsaw Mill. Can I use my regular chain for ripping?
Your regular stock chain on your saw works okay when it is sharpened correctly. All top angles must be the same uniform angle(25, 30, 35 degrees) and your depth gauges must be at the same height, no more than thirty five thousandths below the cutting edge of the tooth. For better ripping results, re-sharpen your stock chain to zero (0) degree top plate angle from the 25, 30 or 35 degree angle mentioned before. The zero degree top plate angle reduces the power needed to rip and produces smoother lumber than your regular stock chain. However neither of the above works as well as Granberg Ripping Chain. - Do I need an Auxiliary Oiler Kit? -
Chain saws deliver oil to the drive links via an oil hole in the top of the bar at the power head end of the bar. Oil has to travel to the bottom of the bar where most of the cutting is done. For smaller bars and small cuts, this system works fine. For larger bars, 24" plus, we recommend our Auxiliary Oiler Kit since it delivers the oil to the cutting surface of the bar. To mount the kit, two holes are required to be drilled through the end of the bar. This allows you to mount the kit on either side so that you can turn the bar on a regular basis for even bar wear.
- How thick can the Mark III cut?
The Alaskan Mark III Chainsaw Mill Attachment can cut boards as thin as 1/2 inch and as thick as 13 inches. Set up and make your first cut, remove this first slab, then use the Mini-Mill II to edge the log. This will give you a three sided cant from which dimensional lumber can be cut. Alternatively, the Alaskan Chainsaw Mill can be used for all of the cuts in various ways; Lower the mill and make a second parallel cut, then roll the log 90 degrees and make a third cut, thus giving you a three sided cant. If your mill is not wide enough to make the second cut as described, the log can be progressively rolled and the sides removed to reduce the diameter, so that the mill can fit across the log.
Timber framing is the method of creating framed structures of heavy timber joined together with various joints, but most commonly originally via lap jointing, and then later pegged mortise and tenon joints. Lengthening scarf joints. Diagonal bracing is used to prevent "racking", or movement of structural vertical beams or posts.
Originally, German (and other) master carpenter would peg the joints with allowance of approximately an inch, enough room for the wood to move as it seasoned, then cut the pegs and drive the beam home fully into its socket.
To cope with variable sizes and shapes of hewn (via adze or axe) and sawn timbers, two main carpentry methods were employed: scribe carpentry and square rule carpentry.
Scribing was used throughout Europe, especially from the 12th century to the 19th century and subsequently imported to North America where it was common into the early 19th century. In a scribe frame, timber sockets are fashioned or "tailor-made" to fit its corresponding timber; thus each timber piece must be numbered (or "scribed").
