I didn't think it 'boring' at all ! Very interesting.

Jerrycans

What a fascinating topic this has become.

Nothing like a bit of "Daily Mailese" to wind up the punters.

It raises our page count

1 gallon (of water) weighs exactly 10 lbs.

Petrol/diesel is a little lighter so say 8 lbs.

20 litres is just under 4 gallons so you'll have 35+ lbs in the can, plus the weight of the can.
That's quite a load. Better to carry 2 cans, one for each arm to balance things out 
As you know the outer handle bits were to allow 2 people either side to carry the can between them

PS
I always thought that jerry cans were 5 gallons 
Have they shrunk over the years or am I misinformed

I tend to use a little 5 litre plastic can for the lawn mower (lasts me about 1 year of mowing).
I get some surprising looks when filling up the LWT - hose in through the front door.
Great ... means I can pull up any side of the pumps. Never been refused service.

I always thought the outer handles on Jerry cans were for picking up two at once, not much trouble for moving them from one vehicle to another say and very easy when moving them about when empty.


This storm in a teacup surrounding fuelling classic cars with unusual fuel pipe placement seems to stem from one event that the chap then wrote an article about. Sure you might occasionally get quizzed by a pump attendant as to why your pouring petrol into your footwell but a simple cheerful explanation is going to suffice for all but the most obstinate characters.

Jerrycans have always been 20litres. They're actually a fascinating piece of industrial design. A full one has just enough air in its expansion area so that it is just positively buoyant. The design was copied by the allies after assessing captured Axis equipment, hence the name "Jerry" can.

Mass is constant. It's just the bad mechanical design of the human body that makes it feel heavier the further a weight, even a relatively light one, is carried.
It's psychological. Mechanical devices don't have a brain.

Hi,

Google says ...

... At our test track, the Kona Electric hauled itself from Zero to 60 mph in 6.4 seconds, 0.2 second quicker than the regular Kona.

Sounds OK to me! Feels good too!

Quote from: GlenAnderson on Today at 12:08 PMI once carried a full 20litre jerrycan a bit over a mile. Never again.

Exactly. My physics teacher at school told me mass is constant. Well, it's not. And anybody who has ever carried anything heavy over some distance knows that after a while anything heavy gets heavier and heavier...

Finished stitching and refurbing my (Leather cover) series steering wheel at last, not too bad a job once I cracked on with it.
