Yes I noticed that you had spelt gravy wrong.  

[Tony Press]

I balanced my 4 blade by sticking some small squares of lead to the tips with araldite and re painting g the whole afterwards to really bond them in place. Wash the bearings out , lube with 3 in one to reduce friction. Do your balancing, then lube with greave when happy with the balance.

Isn't Araldite temperature sensitive- I would think you might fire off weights in hot weather 

[Ray White]

Could you not simply remove material from the heaviest blade until they equalised?

[Steve Bryant]

Ray, that's generally how you do it. The question is how do you determine the heaviest blade and check to see if you've achieved  the desired balance?  There are no holes in our fan blades to mount them on a spindle to hold them for balance etc.
Cheers,

In well over half a century of Austin Seven ownership, I can’t say I’ve even considered fan balance, even with tuned engines and as far as I know, never had a problem...have I missed something, or just been lucky?

[David Stepney]

Yes I noticed that you had spelt gravy wrong.  

Since when has gravy been used to lubricate anything other than the Sunday roast?

[Dave Mann]

I've never bothered because most of the time the fan belt lives under my seat only being fitted for Malcolm Parker's runs.

[Ian Williams]

Stop worrying about it Steve, it need not be in perfect balance and unless dreadfully out it dosen't spin fast enough to cause a problem in my experience.
