A couple of days ago I joined my friend Rich to help out with his new Turbo Saw Mill, and make a video of it in operation. It's a serious piece of kit to be working with!
Here's the video, showing several of the stages in the production of a gate post measuring 8'x8"x8" from an oak log:
As you can see from this picture, it can actually handle much longer pieces of wood than this though - the back end is behind where Rod is stood in the picture below:
The saw is mounted on a carriage which rolls along this aluminium beam:
There's an electric version, but Rich has one powered by a chainsaw engine, so it can be used in the woods. It's a Husqvarna 3120xp, with this small modification to the throttle so it can be operated remotely:
Rather than driving a chain, the saw engine drives a belt, a bit like a car fanbelt:
In turn this drives the circular saw mounted at the other end of the axle:
The saw Rich has is about 20" across, allowing it to make cuts up to 8" deep. The teeth are tungsten carbide.
When in action, a water tank uses a gravity feed to cool the saw, which can run vertically or horizontally, with the weight of the saw blade and the chainsaw engine counter-balancing each other:
By being able to swing through 90 degrees (hence the other name, 'swing arm' saw mill), it means the mill can take chunks out of a log without having to cut all the way across:
This was only the second use of this saw mill - there should be lots more coming up, and I'll be posting some more videos...
