I cannot really help but most alternators have two poles on the rotor and 3 pairs of stator coils, if the W terminal is on one stator coil I would expect only two pulses per rev. I have one on my bench but it's not working yet otherwise I'd see if it gave a pulse when spun by hand. The reason for knowing the diameter of the alternator and crankshaft pulleys is to know how much faster the alternator revs than the engine.

Yes, getting it dry quickly means there is less loss of dry matter (=heat energy) by respiration of bugs living off it. Smaller logs have more surface area exposed to drying air and less distance for water to migrate. Keeping the rain off prevents re wetting and hence keeps mould and boring insects out. I am having to re split [1] my cedar logs , felled 22nd June, and they are 15% mc wwb in the middle, less on the outside having been under a polycarbonate roofed open shed. [1] The morso s11 smokes black, like a car with its choke on, if I put a 5" plus cross section log on as they are so dry that they evolve more woodgas than the secondary and clean burn air holes can supply if put in whole for a few minutes. It's an unexpected pain as being light they also burn fast, meaning frequent loading is needed. Having said that the house is too warm to have kept it fired since I lit it at 17:00, ground floor rooms at 21C and it's still 10C outside.

I'll cross cut with a pushing chain where it needs it too. I was pulled up on my assessment 30 years ago now, for running up a whorl on the far side with a pushing chain, flipping the saw onto its side with my thumb on the trigger for the top branch and then bringing it down with a pulling chain for the branch on my side. That last bit meant the saw was coming toward me. The way I sned a conifer means that this method alternates with the approved method every other whorl.

I wonder if ppr= pulse per revolution?

Yes, I'm definitely under the weather today; I remember the engines in one of the double decker buses being 6 cylinder Gardners, an ozzy chap just up the road from here would buy them, and always the same type, normally ex Manchester ones, convert the top to sleeping quarters and then hire them out for trips to Turkey and beyond, Dave Marsh Top Deck Travel.

I thought they used Gardiner engines like went in the buses and that is on the grill. Last one I saw at work was in about 1983 and it was stuck in the wood with a diff case broken by the internals trying to get out. The replacement was a Northrop and I hoped they had forgot about the unipower so I could "find" it and haul it out for repair. It disappeared over a weekend and no more was heard of it. I think it was about the only dedicated timber extraction and haulage vehicle (matadors being conversions from military)

Nope, Aviva would opt for a default rather than guaranteed income, I've been paid by DWP for 5 years now without having to fill in forms of any sort. Cut my driving licence in half and sent it off too.

Stop it @Stubby I'm supposed to be filling out the form for my pension which starts in December and if I make similar mistakes in that...

Depends on who cuts out the branches and stacks the cord, If you cut the middle of the bend you get 70% stacking, cut either side of the bend and it drops to 50%

Actually 1 litre of beech or oak do weigh about 1 kg

I will edit that 😀

Yes but it's the same as 1 litre of water weighs 1kg but I did make a mistake in my off the cuff reply from having an addled brain, I blame the pneumonia vaccine ;-). It was just as well @gdh queried me.

It depends on the bits of wood to some extent and I made a mistake as I assume fresh wood instead of 20%mc wwb We can say wood is carbon, hydrogen and oxygen plus the hydrogen and oxygen in the 20% moisture. The ratios are approximately 5 carbon, 7 hydrogen and 6 oxygen. that give a molar weight of 5*12+7*1+6*16=163 when that burns it produces 3.5 H20=3.5*(2+16)=63 or 38% of teh dry wood. So with wood at 20%mc wwb thats 0.8kg dry wood and 0.2kg water burning to give 0.51 litres of water. Fresh wood at 50%mc wwb produces 0.7 litres which is 140% of the weight of dry wood burned.

It's because the steam condenses and settles in the exhaust before it gets hot enough to pass out as a gas, wood at 20% moisture produces about 1.5litres for every kilo burned

You need to ease it just over compression, let the recoil retract and then pull it. I have a jonsered 920 that I can't seem to get rid of and it is the same. It would never have been a problem to me twenty years ago.

Obviously it's as you say and just a bit of fun. I don't believe stickers or most signs we see in our daily routine are of any benefit if initial training has been understood and taken in.

I wouldn't discount the possibilities of something being possible, @trigger_andy has pointed out the circular saw stop and I cringed when I saw the video of the designer triggering it with his finger but it was incredible. Similarly professional motorcyclist now have suits that inflate explosively if a crash is detected OTOH a sticker may work

Even as late as 1994 people weren't using chainsaw trouser here, prior to 1981 they were unheard of here.

I'm sure the little difference it will make as earth orbits around increasing entropy as it dissipates the energy it captured from the sun is in the order of gnats pissing. The bottom of the pond will not grow colder than 4C until the ice thickens so deep that there is no liquid water left.

Yes it could happen but most collisions are between vehicles and vehicle hitting crash barriers and seldom do they take down bridge abutments. I wonder what the life of a HV overhead wire is and whether the wear is related just to rubbing AND/OR current passed . When I rode a train cab diesel electric it took 2000 amps to get it rolling then very little on the move. This is the nub and in this case it's real time use of electricity, not off peak charging when everyone is asleep. I was not sure whether the lorries were EV with battery or had a diesel when not connected to the overhead but the figures would be interesting. Laden a 38tonne lorry gets about 6mpg, that's an impressive tonne-mile figure and about 8 times more than a typical car uses. Cars do about 5miles per kWh and have 20-30kWh batteries. So if the lorry has 100kWh battery it can do about 62 miles between leaving the overhead and getting to another charge point assuming the initial overhead running provides enough to fully recharge the battery. Of course from a pollution point of view moving the power production to a centralised system is likely better than having a diesel running but from a climate change CO2 dumping position do all the production and transmission inefficiencies match the non optimum running of a diesel in a lorry? I doubt it so somehow the electricity needs to come from a non fossil fuel source..

Like this?

Okay sorry if I misinterpreted. So we agree good insulation works both ways and a house with high thermal mass will have less temperature fluctuations with exterior insulation. I still haven't attempted wall insulation for my solid walls because it would destroy the look of the two tone bricks.

My second try at replying as lost first in cycberspace. Twenty years ago I did a lot of work in UniS grounds and woodlands and wasn't aware of that. They now have a woodburner at the sports complex. I guess the sizeable lake is also heating a sizeable building. The thing about a natural pond is that the coupling with groundwater exchanges more heat and as @Billhook says a running river is picking up heat as it travels. Also water is good at absorbing infra red radiation from the sun. I wouldn't worry about solar thermal over heating in this country and even if it did there are ways to deal with it, freezing would be a bigger worry. PS I experimented with flat plate collectors but with a small South west facing roof opted for solar PV for the available space.

Saves your back too. I find the type you linked too flexible so prefer the all steel ones but you do need to stiffen the stupid attachment by welding a bit on to stop the flattened tube flexing. I have had mine for over twenty years and they used to laugh at me when I took them to domestic jobs. https://m.media-amazon.com/images/I/61K7TLZi1IL._AC_UL320_.jpg Very good for picking up dog turd too
