When I retired(mostly just tired) from building custom residential and commercial cabinets for over twenty years,I wanted a way to keep my hand in. You can't really retire with a shop full of woodworking tools and machinery. I decided I wanted to cut my own lumber so I could build grain matched cabinets and furniture. The cost of a commercial bandsaw
mill was out of my price range, so I built a "Granberg" type chainsaw mill. With an 8 h.p. Stihl chainsaw it works well enough(not near as fast as a bandsaw, though). After cutting several large trees and ending up with just a few good boards and a mountain of offcuts, limbs, branches and stumps, I started making tables and benches out of the scraps. When I saw
the interest that these generated I started looking for ways to increase production and build other types of furniture.Having built custom cabinets I just assumed I could build log furniture.(haha). I quickly found out that standard wood-working tools have very little use in building log furniture. The problem is every log is unique(to a cabinet maker that
meant bent, twisted and bowed).There is no "side" to run against the fence, nowhere to take a measurement from. Without a lot of complicated "one off jigs" for each log I didn't see a way to apply mass production. A woodworking lathe spins an unbalanced log so fast that vibration alone is enough to jerk a chisel out of your hand and my lathe only has a 48" capacity. Even a large drill press has a limited stroke and capacity between the column and drill bit. I wasn't impressed with the pencil sharpener type tennoners.I experimented with a plywood benchtop lathe I built that uses a router to cut the tennon. I had run milling machines, metal lathes and CNC routers before, so I decided to build a real machine that worked on the same principles. As I was designing the linear action for this I realized I could build just one action and combine different tools for different jobs. I used 3-D solid modeling software so I could build virtual mock-ups to calculate range of motion, torque, and feed rates for each task. I kept the design simple using "off the shelf" parts. It functions as a sawmill(22" dia.x98" length, also plunge cuts), a large capacity mortise machine(24"x96" bed, 14" vertical stroke), a large capacity drill press 24"x 96" bed, 14" vertical stroke), and a lathe(10"dia. x 108" length). Long story short, I haven't built any cabinets for quite a while. Go to drop box links for more pics and info.

Nice work. There are hydraulic chain saws out there. usually truck boom arm mounted (might find an auction item). And variable speed DC motors on often free treadmills.

WOW.....I missed this thread...right down my alley....a creative mind using basic multipurpose setups.

I built a reclaim log 1800 table a few years back in a trestle style through bore wedged bar and draw pinned mortised uprights. YES it takes creativeness as NOTHING has a flat or square to start from.

Sorry for the late post...just all thumbs up on your achievement!!!!
