Wheel Weight

[Eveready1100]

Just wondering if anyone can tell me how much the front wheel weighs minus the tyre, discs and axle. Just the bare rim and bearings.

[Yahman]

Your in luck! I'm working on a front wheel and have it stripped down for new paint.

Bare wheel = 12 lbs 14 oz
Bearings = 7.9 oz
Bearing spacer = 4.4 oz
Seals = .8 oz
Speedo drive washers (behind seal) = .5 oz
TOTAL WEIGHT = 13 lbs 11.6 oz not including the valve stem.

1 ounce = 0.0283495231 kilograms

Well answered question! Nice breakdown of weight.

Thanks heaps for the info Yahman.I was just about to pull the tyre off my spare bike's rim when I realised if I did that, I wouldn't be able to move what's left of the bike from the back shed to the garage which would've upset my workshop reorganisation plans (tidy up) somewhat.

Hi subike,
that was in English.
There's conversion charts to turn the numbers into that metric rubbish for those who have been legislated away from the Imperial system of weights and measures.

gee did you think i was serious?
XS11's come from The Emperial Empire of Japan
nd were built using the Metricsystem of measurements
But then I guess they should be called 67.126118504ci XS Yamahas.

There we go. I gotta get custom side cover decals that say XS67.1

That said, for weight measurements those of us in non-european countries tend to be more comfortable with weight in pounds and ounces, just as the weight of the bike and such is referenced in SAE measurements. I think that when you pulled on the legs, everybody yanked back (no pun intended (or was it?)).

Scale

Hey Yahman,
What else do you use that very sensitive scale for??

[fredintoon]

Hi subike,
Gawd no! Did you suppose it of me?
Seriously though, the Imperial system:- {12inches = 1 foot, 3 feet = 1 yard, 22 yards = 1 chain, 10 chains = 1 furlong and 8 furlongs = 1 mile} stretches the mind with it's complexity while any metric moron can move a decimal point as their brain turns to porridge.
BTW, the mile (1760 yards ) is equal to 1,000 left-rights of a Roman Legionary (they were short little bastards) so us Brits have been metric since the time of the Caesars.

Hey Yahman,

Calculating postage.

I do have a scale that is as sensitive as you speak of, it's used for weighing the ribs in a model airplane wing. That way I can achieve a better balance between the left and right halves of the wing during assembly.

I know what you was getting at though.

Hi Larry,
I used to slather another coat of dope on the lighter wing but that was back when we used tissue for covering.
However what's more necessary is to make sure each wing lifts the same, eh?
BTW, I'll tell my eldest about weighing model airplane parts so he can tell the cops why he's carrying an electronic pocket scale.

Hi Fred,

With electric planes it's desirable to build them as light as possible.
Yes, wing loading and proper alignment of the wing surface's is very important also.

I'd make sure your son knows the lingo to support his story with, although I doubt a cop will believe that he's carrying the scale for just that.

Hi Larry,
does anyone use microfilm these days?
Back in the UK many years ago you could buy electric flying models that used lightweight disposable batteries.
The batteries were little blue plastic envelopes that came in a tear-off sheet like postage stamps. You tore one off, clipped it into the model and squirted salt water into it's envelope to give about 20 second's worth of power just as you hand launched.
(A thought; how about the batteries that are built into self-developing camera film packs? They are flat enough to fit inside a wing and it's claimed that 2 of those will start a car.)
And it's not what the men in blue hats believe, it's what they can prove on you.

[Yahman]

Fred,
There are a number of different types of film used to cover model planes these days, but the only use of microfilm is on the F1d indoor duration models. The rules state a minimum weight of 1 gram and a max of 2 grams.
The battery of choice these days is Lithium Polymer. I have never heard of anything like the batteries you described, very interesting.

Oh yes, the burden of proof...
