Actually, the raised potions on the sides of 55 gallon drums are called "rolling hoops".

Maybe, but they are there to improve rigidity.

...it looks like the lads at Wikopedia don't know what the ribs (rooling hoops) on
the 55 gallon drum are for either.

"In accordance with practices conventional drum walls are made with two rolling hoops,
which are generally outwardly extending annular protrusions formed about the outer
circumference of the drum. The rolling hoops are vertically spaced from each other
along the length of the drum wall. If the rolling hoops are shaped at an acute angle,
the vertical strength of the wall is diminished which adversely effects the adaptability
of the drums to vertical stacking."

http://www.patentstorm.us/patents/5730315-description.html

As a matter of fact....the rolling hoops weaken the sides of the drum, and the drum is
more likely to collapse.

Also, the sides of the drum don't need to be made more rigid. Their round shape gives
it enormous strength....just like an egg....and when the drums are full, they certainly
don't need to be made more rigid.

Fact is, pallets of drums are stacked one on top of the other. If one wanted make the
sides "more rigid" and strenghten them to keep them from collapsing....

....the ribs would be running vertically on the sides of the drum.

Just keeping the record straight.

FBD.

You will find all kinds of claims in patents, many of them not true. Fact is there is little need for verticle rigidity because a full drum will not collapse from weight of the above drums, unless the sides rupture. That is because the liquid itself supports the weight as long as the sides don't buldge and rupture. It has been a long time since I have rolled a drum around, but as I recall the "rolling hoops" don't even contact the floor on some drums, the bottom and top sealing ridge extend past them on some designs.

This manufacture of steel drums claims its double ribbed rolling hoop improves stacking strenght and resistance to vacume damage.

....yo Sport....

....you failed to mention that the newly invented Greif drums are a recent vintage, and are
the exception to the hundreds of millions of the regular 55 gallon drums that were made with
the protruding "rolling hoops".

Funny too, how even the Greif container information refers to the ridges as rolling hoops.

I guess the exception to the rule still doesn't change the facts about the standard,
does it ?

Let's get back to glow fuel instead of arguing over the design intentions of 55 gallon drums.

I will agree with that.

Kmot, how's the Ram doing? Keeping a close eye on this I want to see what comes about your old fuel. What engine are you going to run it in? Do you think it will matter in a 4 or 2 cycle?

Here is another question. If water absorbed in fuel causes the engine to run hot or slower, then what about the effect of flying in 100% humidity? Would not high humidity in a running engine have the same effect as water dissolved in methanol?

100% humidity would be either rain or dense fog. There would be performance issues.

Yes the humidity would have the same effect. But water does not cause the engine to run hot. It may or may not cause it to run slower. Drag racers add water to their methanol and nitro fuels to decrease detonation. If it does that then it will actually make it run faster. If you have water in the fuel and you do not readjust your needle then it will be lean because the water displaced some fuel, but if you readust the needles then it should be fine. I think Downunder ran some tests by putting water in the fuel till the oil seperated out. He could get the engine to run fine till the oil seperated out. I don't recall the amount but the percentage of water was less than I would have thought.

Actually it is possible to be 100% and no rain or fog, but you are right on the edge. The rain and fog does not count toward humidity. Fog is in excess of 100% humidity as the air cannot dissolve any more water so the excess water forms droplets. It is common for the humidity to actually be somewhat less than 100% in a rain storm, if it were at 100% then you might have both rain and fog. I have flown in rain a number of times, including touch and goes (kinda fun making rooster tails

), the engine ran fine in a fairly moderate rain, though I suspect a dense rain might drown it out if the engine is allowed to idle.

True, and the converse is also true as fog can develop with less than 100% humidity. Also, fog forms easier with at least several knots of surface wind.

I've flown in the rain too and didn't notice any problems with the engine.

Here is some info from a racing site, note water is used up to 10% to reduce detonation. However this would cause oil to seperate at that amount. Also racecars don't use glow plugs, I suspect this much water would require a hotter plug.

I was interested in the glow fuel and the container information.

Well, just wondering if old glow fuel is still good to use? Pink-OK- Brown-Not- what a concept! I say just try it, if it works, GREAT, if not, OH WELL.
Just me.
