 Having said that, the more I think about it, the more obvious it is that it's a bad idea ( to use a modified saw for work). 

 

I think its a bad idea not to .  They are more efficient , cut faster and run cooler . Who wants to be trying to chase that back cut with a stock saw bogging and struggling ?

I guess the lack of power on an 881 is also down to cooling etc? If you had a 125 air cooled engine running tits out like you do with a saw she ain't going to last long?

Can you get 20hp out of an 880/881?
Would it last?
How much £?

The question I was about to ask.

And I suspect the answer.

I'm not saying they aren't a good idea from that point of view; I'm simply saying you are opening yourself up to (the possibility of) a world of agro if you use one for business purposes. 

 

Imagine an employee has a hearing test and is found to have some damage. We buy PPE based on the risks that we know about. Ear defenders are designed to take the sound from a stock saw (limited for safety reasons) and reduce it to a safer level. Try telling your insurance company that you deliberately had a mod done that made the saw louder than the set limits and see what they say. 

 

I'm just thinking about this from a business point of view, I'm not saying that ported saws aren't better than normal saws, or that Spud is doing anything wrong.

Having had experience of a HSE investigation if you kept your mouth shut they wouldn’t know if the saw was altered they only look for chain catcher, chain break, stop switch maintenance records, training and issued and signed for PPE they didn’t even start or run the saw. Personally I think I could have shown him a disc cutter and he would have been none the wiser

That is a good point. You won't get anyone from the HSE who knows his backside from his elbow. You'd have to rely on the possibly injured employee not to mention it though.

We had a jobsworth, I mean HSE, turn up onsite once.  I was up a big oak tree and all the kit was laid out on the garden.  Spill mat for the fuel etc.  Rescue kit and first aid and all the RA and MS in a waterproof folder.  Pretty much a perfect site.

 

Mr HSE starts going through everything and cannot find a problem, apart from one of the saws.  Which happened to be one of my ported saws.  
 

He picked up on the fact that the stickers were missing.   OMG shock horror, no stickers!  The company owner just said, that is the guy up the trees saw, he is from the North and very grumpy.  No one else is allowed to touch his saws let alone start them.

 

The HSE said ok and went on looking for more problems which he didn’t find.

Yup, full power Aprilia RS125s have been known to make upwards of 30bhp, but that's a liquid cooled motor with a 300x300 radiator designed to run in a 70 mph cold air stream so I'd imagine that raises the power ceiling significantly!

@Rich Rule 

That’s cool you said that, it’s people like that,  that give a lot of other people a bad reputation.

 

I can’t remember where I read it, but some hs guy on the railway picked up on a very little hole in a mesh visor, and he pushed his pen through it, and said this could be a bit of wood that hits you in the eye. the guy who’s helmet it was spoke out and said I wear glasses, but he still had to get the spare helmet out. Bloody jobs worth hs guy, and yes the stickers tell you a lot of things if you know wtf the symbols mean.

 

anyhow ported saws are great, just don’t knock it till you tried one.👍
