First modular Chainsaw

We love a bit of forestry history here at Excelsior! Shout out to L.M Strunk who was the first to patent the modular chainsaw back in 1958.

For those familiar with the inner workings of a chainsaw, will notice the similarities of todays power saws and this picture. First off, the bar is attached to the saw body via bolts allowing the bar to be flipped so there's no uneven wear.

The chain is driven by an outboard sprocket that allows replacement of the sprocket to be made easily without interfering with the inner working of the power unit.

Most importantly, the chain itself is kept oiled via a grub screw that runs oil through a hole in the bar to the rails. Prior to this design, engine oil was siphoned to carry out the same task.
