    Yep, agreed, and even on a cast iron cyl it`s real easy to take off too much so unless it`s just a quick glaze bust a mic is probably needed, cheers

    Yeah, Iv`e deglazed using the flexi-hone for many years, fine on a 4 stroke, but putting it into a 2 stroke cylinder at enough speed to do anything will probably cause excessive wear on the tool and the cyl as it hits the edges of the ports, and to use the expanding 3 hone tool you really need to be able to pass it through the cyl to almost the centre of the stone in each direction in order to get an even honing result, not possible on a saw as you can`t take the head off. so it`s a fingers job, it`s only my opinion.

    You need to shake them up as the solids settle, used both, no complaints, obviously no comparison to the real stuff but seems to last a few years before it needs another coat, £8 a gallon

    Hi, i`ve used it for outside timber a fair amount, same stuff from toolstation, seems quite good, dries in and the stink goes away quite quick, I would think it`s better than smearing your work with dirty engine oil but not as good as the real thing as has been said. Prefer the light flavour myself, think it looks better, cheers

    Hi, if you buy a gallon of good quality pure tung oil, which is, [or should be ] the main constituent of all the named products, you won`t go wrong, it`ll make up into at least double when thinned, it`s well worth having on the shelf and is a joy to work with. imo. cheers. Aye and try it with real turps rather than the usual shite

    Yeah, rain bouncing up from the ground can make a right mess of your beautiful work in no time, specially if it`s muddy, as soon as mud touches nice new wood it can leave horrible stains, cheers.
  7. Macpherson
    Thanks Codlasher, I have a similar project, very useful info on the different timbers and as for the fixings, there`s nothing spoils the job worse as it silvers in than the black staining from iron nails. cheers

    Big combi ladder for me, if it`s windy you can loop a rope round it to hold it in place, or extend the stablising bar with a 3"x 2". I`m gettin old too !! cheers.

    Hi, google auto electrical supplies and type in "HT connector" it`s a bit clumsy but might do, cheers

    Hi, try googling Intra laboratories, they were mentioned by someone on here recently, they sell borax powder by the kilo, and have mixing instructions and concentration details for different applications, also quite cheap. cheers.

    Hi, when I got the granberg grinder I did notice that the stones were accurate and good quality compared to some others i`d used, it`s fine with the thread , the diamond ones are on ebay. cheers
  12. Macpherson
    Yeah, sorry, can`t find it either.
  13. Macpherson
    Yeah,a possible 14,000 -zero in less than 1/2 a second, I doubt if the brake band is the only part that that suffers.
  14. Macpherson
    Hi, you should be able to download it as a pdf, cheers

    Personally I prefer the teeth to be at least hard enough to ruin an oregon file in no time, after all a saw chain is the only cutting tool I use that is soft enough to file, for example, I wouldn`t want a drill or a chisel that could be sharpened with a file. Imo I don`t think a dremmel type grinder is capable of overheating the cutters, whereas a bit of care is needed with the disc type. Cheers

    many older engines had a roller on the drive side and a ball on the other which held the crank in the correct position, however that`s irrelevant when it comes to the 560xp. It remains a mystery !!
  17. Macpherson
    I take your point, in many failures there`s no way of telling what happened first but over my time i`ve replaced many bearings due to the state of the cage even when there was no apparent excessive play, not just plastic but bronze and steel also, particularly in a crankshaft situation the cage gets it where a ballrace has been used to control endfloat for instance. cheers
  18. Macpherson
    Oh well , just a thought
  19. Macpherson
    Hi adw, I take your point , and would agree with the probable reason for bearing choice, but I have also seen the various ways that they can fail, mainly in motorcycles though. Hi njm ,It would be interesting to know the condition of the cages in the failed bearings ie: worn out, melted, roasted brittle or what ? I wonder if the brake being flung on at speed could be responsible for the transfer of a shock load or kick through the crank delivering a "knock out blow" to the weakest link, the cage. cheers.
  20. Macpherson
    I see your point, but it seems that a lot of these saws aren`t lasting long enough to get minor this or that`s to mask, and the observant operator is being tricked by the AT when the situation becomes critical, at these engine speeds in a lean burn engine, there is really no margin for error.........imo
  21. Macpherson
    hi paul, if it`s any consolation, I had a similar hand injury-operation 30+ years ago, don`t worry you`ll get it back, just get it moving as soon as you can. Are you right handed, makes things tricky, cheers
  22. Macpherson
    Let me shake your hand sir, I totally agree with you. No fuel no oil. When it`s spinning at max rec. speed of 233 times a second which is faster than ever, combined with a claimed " up to 20%" reduction in fuel usage even before the AT compensates for a prob like a dirty air filter is it any wonder that a dried out wee piece of plastic gets roasted. cheers
  23. Macpherson
    merely curios.
  24. Macpherson
    I don`t think that being able to understand the tools you`re using makes you a dinosaur. I Was in the company of a recently trained guy just last month, when I eventually couldn`t take any more of the brake being flung on at full revs and tried to advise him otherwise, I was told that`s how he was taught and to mind my own business, little **** !!! Anyway back to the thread, I can see how the method of assembly of these engines could easily leave a preloaded pressure on the bearings and it`s no surprise that the plastic is the first thing to suffer from the extra heat that could be generated by this. Sorry, in my previous post I didn`t know the bearings were specials, sounds like crap design. Is it autotune ? Cheers
  25. Macpherson
    surely with warranty it won`t cost you anything then !! cheers
