As I cannot learn new tricks very well I would initially tie the two ends with a double overhand knot and then tie the butterfly with the knot in the loop. I either create two opposing loops, overlap them and pull the middle up through the intersect or wrap three times round my hand and pull the middle loop out from under and then over the lot.

Looks like a rust fungus to me

This is the sort of repair which I find can be done with carbon fibre tape and epoxy if you have 24 hours to cure it.
-
What I have experienced is similar but not so much resins and 2t oil being left, often in the crankcase which makes initial starting a bit smoky. I haven't started my 084 for a year or three so must try that, not on a day of quiet though.
-
Is this just a butterfly with the two loose ends where the loop would be? I can never remember how to tie a zeppelin but the alpine butterfly is such a useful knot that to use it to join two ropes is easy. I think it is a strong knot too with about 75% rope strength retainedwhereas the bowline is 60% and sheetbend 50% (mind I cannot see why there is this much difference between the latter two as functionally they seem the same).

Dosko dealers in U.K.
openspaceman replied to The Surrey Garden & Tree Company's topic in Arb-Trucks
Their bluechip was a copy of the Dosko so that doesn't surprise me. Certainly long lived equipment as the chap I help out occasionally still uses both. -
Dosko dealers in U.K.
openspaceman replied to The Surrey Garden & Tree Company's topic in Arb-Trucks
I think only the small ones are imported now and dosko show their dealer: Hire Supply Company (UK) Limited Units 7-10 Eldon Road Trading Estate Attenborough Nottingham NG9 6DZ Telephone: 0115 946 1988 Kim at Danequip seems to be able to get spares still and of course sells her own stump grinders -
It looks useful so once you have the sucking air sorted out you can look at whether it can be sensibly speeded up. I cannot see from the picture what the difference in diameter of the piston rod from the piston is but a pressure sensed regenerative valve could be inserted between the ram and spool to speed up the power stroke on easy wood, it would then slow down to current speed if it encountered a knotty bit.

No harm in checking ram seals but on a double acting ram there is nearly always a zero to positive pressure on both sides of the piston so not much scope for sucking in air there.
-
So the oil reservoir is the box section that the ram block rides also? If you raise the splitter knife end up on a chog about a foot does it make any difference? I'd change those clear plastic return lines for something less affected by heat than polythene. Once you can be sure the suction side of the pump isn't letting air in then it's most likely the shaft seal on the pump drive.

The triblade worked okay on the stihlelectric kombi with backpack battery I used for a few hours clearing overgrown footpaths but I don't think it would have had the power to run the shredder (mulcher) blade effectively, you really need 50cc for that.

Free if you fish them out of the canal

If you ever get one and fancy a 2.3 engine to put in it I have a rebuilt one with less than 300 miles on it in my garage which needs the head torquing down and rocker shaft put back in

New bar and old chains... they don't go together!
openspaceman replied to Rob D's topic in Chainsawbars
I take it you are referring to the your original picture here? I was considering why the blueing might be worse nearer the bottom of the bar groove, on the assumption that blue shows a higher temperature event than straw coloured. This too would explain the chipped nose in the picture I reposted. -
New bar and old chains... they don't go together!
openspaceman replied to Rob D's topic in Chainsawbars
This one strikes me as being caused by a worn drive link having peened a tie strap and making the joint too stiff to straighten as it comes off the sprocket. The original picture looked like blunt chain and too much pressure overheating the bar. I would have liked to see the paint stripped off the bar to see how much of the blueing was caused by abuse and how much was from manufacture because some seemed to be at the groove bottom which might suggest a drive link bottoming out. -

I'd forget to put it back again when I reverted it to sawing
-
Is the ram for the box splitter single acting and returned by the spring or is that something to do with the trigger for the return?

I can't see that being a problem it was just the reference to windscreen washer fluid I was picking up on. legionella thrives in warm static water systems. This is why some renewable energy heating systems have to be heated up to more than 60C each day, to kill off the bacteria, with another support fuel.

Now or later?
-
On screenwash use, as you mention it; a bit of warning washer bottle is often in the ideal place for legionella bacteria to thrive, the bugs love the warm to cold to warm cycle of the engine compartment, professional drivers have a higher incidence of the disease from repeated exposure to the aerosol from other vehicles washers, so it's important to use a washer fluid in strength enough to kill the bugs.

Three good bits of advice there though I've not done any fencing for 40 years

I can't say it would make much difference to me but chances are I'll be burned anyway. Back in the day I was regaled with stories of bits of fat being flicked at other meds in the morgue/lab.

That's slightly different as it uses a Vee belt drive rather than a cutterless chain. I would have thought the type with a Vee belt more sensible but with a guard. I wonder what happens to the saw's oil pump, presumably it's blocked off so the pump still has lubrication. My old atom drill used a cutterless drive and oiled as normal but then it didn't run for long periods enough to wear noticeably.
