Spuds Porting and Tuning Thread

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 

Now this is an interesting one.......firstly as it is pretty much what I said about my time in manufacturing and what I had to administrate as a Production Manager and.....note the check for chain catcher, chain break and maintenance records.

How many out there could supply an invoice for a chainsaw service that was carried out in the last year and how many are running a top handled saw with a missing chain catcher?

I purchase 15pcs of MS200T chain catchers at a time because only 2 in 10 MS200Ts that come in have a chain catcher and most have a chain brake full of chip that is a bit...hanging!

Then there is the question of Chinese non OEM parts and the non CE marked Chinese copied saws. Again a pretty grey area.

The few times I have been involved with the HSE, they have looked at maintenance, safety device testing, staff training and training documents.....different industry but the same process!

Puwer requires you follow that manual and have it with you K . 
 

Alas, I’m not convinced about that either.

 

If I take (as a starting point) that I think that I can legally allow my employees to use a most excellent ‘spudded’ saw (devils advocate, you understand) could you show me where it says I can’t?

 

 

love and peace.

I will probably never own a ported saw , as I generally just pick up a bigger saw , but Spuds work on top handled saws certainly is a benefit , just use the get-out I put up earlier K

I had the Yamaha RD125YPVS in mind....water cooled and a very interesting power valve on the exhaust port that works on a cam system lowering it for low revs and then raising it as the revs increase thus making much more power plus the porting arrangements will be far more advanced!
Get some space frame and a Rotax engine...that would be interesting!

What do you reckon HP you could get from an 880/881?
And what will it cost me?

Liquid cooled sounds really heavy.

Well, you can do what ever yr brief says you can !  If yr manual says do not modify a tool ( any tool in point ) then yr stuck with that regarding what you give yr employees . If I decide I want to use Spuds ported saw , thats my own choice , and I am sure I will enjoy using his efforts . K

I have ported a small number of 088/MS880s, the 088 was sort of bonkers as it picked up far faster after it had been done. I don't own a dyno so have no HP figs and having done so few, don't have any gains info on them. I can share the owners details if they are happy for me to give them to you.

Cost wise.....read my post from last night It will tell you what you get!

A manual......

 

 

 

I don’t own a 500, or even use one, but they seem to have a bit of a following, so I chose it pseudo-randomly.

 

Anyway..... after a quick skim through, there is mention of:

> not modifying controls

> not fitting non-stihl accessories 

> making sure the little safety sticker is there.

 

Nothing about actually modifying the saw itself.

 

As I read the manual (very briefly), the most likely no-no’s involved with porting a saw would not be the porting per se, rather....

>accidentally cleaning off the little safety sticker with all the other burnt-on crud and crap, 
>putting in a champion spark plug (if OEM is NGK), and
>sticking on a Sugi bar and an Oregon chain.

 

 

I may well be wrong though.

 

 

 

 

Kind regards.

THIS.

100%
 

In my dealings with HSE, this list is the starting point, and if all of is in order, it’s also pretty much the finishing point.

Oh, and PPE. And the risk assessment (obviously). Errrrrr, and maybe method statements. Ahem.

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. 

 

 

Ok .
