no previous part Part 1 of Sawmill Short Log Clamp series no next part

I was given an apple tree to cut down and the plan was to make boards out of it rather than all logs for turning. I had never had any apple boards before so i consulted with LJ KPOSTY about doing it on his sawmill. The clamping setup would not hold a log that short (33”) so I made him a clamping system similar to the one John Goodwin uses at the Dead Tree Salvage mill in Casa Grande, Arizona.

I had to modify the location of the front rail because the bar support on the right side is out farther than the left side..but no worry, we just drilled a new mounting hole in the front to back perforated tube and bolted it on.

It is adjustable front to back and up and down by the use of the red pins in the perforated tubes. the front to back perforated tube can be moved side to side on the Unistrut channel because there are floating nuts inside the channel that can be used in any of the slots .

The clamp with the teeth in it is removable and just the point of the 5/8” screw can be used to bury into the log. The clamp is made such that the hole in the back has the center just above the top of the teeth so there is a natural down force on the piece being held. he can now cut a piece as short at 26”.

More back stops are in the works as is a V clamp for hold rounds standing vertically.

Cheers, Jim

Nifty set up Jim and well worth the effort for that apple wood. I always try to split up the way cutting, some for boards and some for turning when possible. I have a ornamental tree sliced up waiting to dry.

Good work Jim…Any milling of wood is fascinating. Just so good to see workable lengths of timber being formed with very Clever Engineering.
Well Done…Regards…...Cliff

Thanks you all for the good comments. It sure enhances the mill to make it more versatile.

Hi Dave. Kan and I cut the tree down….took 5 logs to the mill and the neighbor delivered 3 pieces to my barn for turning. All the rest of the tree was picked up by a guy for his smoker.

Hi Danny…........Unistrut was the way to go. It is galvanized but I sprayed everything with stainless steel paint also because the mill sits outside.

Cheers, Jim

Thanks, Mads. There are now two more log clamps for holding them vertically in the mill to cut rounds. One is for the mill in Arizona.

Cheers, Jim
