Would This Work?

Thinking about the hazard presented by the top side of the chain - no need to give examples. Wouldn't this effectively render the top side less dangerous in the event of an accidental contact? I was thinking about gaffing out on a pole while starting the cut, that kind of thing - not to be used all the time but in higher than normal risk situations.

 

It would be an extension of the felling dogs, made of spring steel. The same width as the bar, and the two edges blunt or rounded to avoid snagging on wood fibres. Anyone know if this has been invented before?

Would stop it contacting accidentally but would stop you using the top side at all ( undercutting a stem prior to the top cut etc etc ) .

Yes thats true. I suppose it could have a quick release mech so you could attach it to the dogs/spikes without unbolting the spikes. Would only be used for situations where one really wanted to reduce risk at the expense of productivity.

It would have to be thinner than the chain/bar combo so it would follow it into the wood, but as the wood compresses behind the cut it would trap it.

 

I can't see it working.

That could be an issue...I imagine it being about an inch wide, and no thicker than the bar - maybe 2/3ds the thickness of the bar - so the chain width would be substantially thicker. Do you think there would be enough compression one inch back from the bar top to pinch? Oftentimes I buck halfway through a log under tension before it starts to pinch the bar. One would have to use it judiciously, more thinking of horizontal cuts on stems while gaffing, and I suppose a wedge would be required.

I think if it was only going to be fitted to saws used to crosscut very small stuff, where pinching wasn't an issue; or one never intended to bore or undercut, then it might be something to develop. Perhaps for the occasional firewood processing person. But other than that, it would make it too restrictive. But the occasional user will pay good money for a gadget, rather than get training and I presume that's the market you're aiming at.

Its an old idea that never caught on. Its so old, this one has a Villiers engine

Not sure I would want that hanging off my harness!

Some people, eh?

 

Back in the day when men were men you would have been glad of an advanced bit of kit like that,,,,,,,,,,,,,,,,,

Ah yeah, thats probably where I got the idea. Feck, everything been invented already. I was thinking the target end user would be myself actually. Bit of a sissy, me.
