Yes i use one of those as well. Magnetic mounting is virtually friction free giving a very sensitive balance.

Hi Percy,I used to sand them but my prop balancer wasn`t much good so they were worse when I finished than they were before.I need some fuel proofer so I can get some clearcoat at the same time as my balancer.

I agree with Percy that its best not to sand - but to add. But it doesn't have to be fuel proofer though!

I use CA! One drop 1/3rd in from the tip then a quick wipe with your finger towards the tip to smear it (definitely quick though - you don't want to end up stuck to it!)

Electric flyers are more likely to have CA than fuel proofer!

PS You also get the pleasure of peeling the CA off your finger tip that evening!

And CA is cheaper still - because you already probably have it! wink 2

I brought a (cheap) HK magnetic balancer used it until I checked it for true and found the cones were out so after some research brought a Dubro Tru-spin balancer which I have found to be more versatile and of course accurate.

It is capable of balancing props larger than most other balancers i.e. ones in excess of 12inch diameter plus spinners etc. This can be aproblem for magnetic balancers where the clearance between shaft and bed is not great enough.

P.S. Apologies if link does not work but have just changed to Mozilla Firefox so unsure if it worked correctly.

A pencil stub sharpened both ends makes a good cheap fingertip balancer

I bought a cheap fingertip balancer to make a magnetic balancer with. The balancer shaft turned out to be stainless steel...

I also use the Du-bro "wheel" type, for its capacity and accuracy.

Re sanding/cutting props, well I always 'dress' moulded props by shaving off the moulding flash and cleaning the seam up with wet and dry before balancing. If the prop is only slightly off-balance, I'm happy to use a 10A blade to scrape the rear face of the heavy blade, which I then polish with wet/dry and or Autosol. If it's badly off, then the light blade gets tape or varnish. Wooden blades get the varnish treatment.

I'm with Mike T here in that I sand the very trailing edge of the heavy blade to make them balance......

That said it probably depends on the prop....as a mainly IC flier my props tend to be a bit thicker & chunkier than a typical electric prop...

Look on YouTube. there are some very good videos there. I found the Horizon Hobby one very good. If I remember rightly it uses the Dubro gadget.

I bought the Great Planes balancer and am very pleased at how sensitive it is. Thoroughly recommended.

I would highly recommend the Du-bro one. I've used it on my props and my EDF's, and never had a problem.

I use small bits of pvc tape on the back of my props. Before anyone says it....I've never had a piece of tape come off. For my EDF's I use the tape rolled into small 'balls' and then CA to hold it in the hub.
