Title: How wide is a wheel?
Post by: Ron on July 28, 2008, 17:37:26 PM

Hi All,

Just started (at last) my Slingsby Skylark project.
But I have a small problem.
It has one wheel in a box just behind the cockpit area, and I have to make sure there's enough width in the box at the 'keel and formers' stage.
So how wide is a 3" (75mm) wheel?

Searched the web but can't find anyone giving widths. :?

Hi Ron,
Difficult to say as that will depend mostly of the wheels maker...

But by experience, I would say between 20 to 30 mm... :?:
30mm would be the maximum size at this diameter...

Hi Fred,

Thanks, that might do.
I've got 32mm between box sides at the moment, provided I put any reinforcing on the outside of the box.

You don't stock wheels I suppose? :lol:

Should fit !
No, but we can have them  :D

If you tell me the specs you want.
I'll check in my stock aswell, I might have one to give to you...  :?:

How wide is a wheel?: about 5.4% of a length of string :roll:  :D !

OK then.
If my wheel box is 30mm wide that makes a piece of string about 55.5 cms.
I've often wondered how long a piece of string is. :lol:

Wonder if that applies to baler twine too.

This wheel has to be 3" dia, preferably with a Michelin tyre and air-cooled disc brake.
Hmmm :roll:

Well, now that we've sorted out how long a piece of string is, can we move on to determining how low "low" is (as in: "how low can you go?"):D ?

who really should be working..

To find out how low you can go you need some negative lift.

Now we're getting threads crossed.

Crossed threads?
That's string again isn't it. :?

Oh I give up :roll:
