prop shaft balancing

I've had the prop shaft blasted and sprayed and there's probably a larger than average chance that it will need re-balancing. At least, that's what I reckon. Is this likely to be the case? If so, can anyone recommend a company in the southampton area who might be able to do it? Or better still, is there a way of doing it yourself?
Thanks in advance

Try it first and if you get a wobble fit a big jubilee clip around the prop. If the wobble gets worse turn the jubilee clip 180 degrees and try again. Keep experimenting until you're happy
Probably do it to see if it works then get it done properly, you don't want a jubilee clip flying of when it's rusted through in about ten years

That's a good idea. When I spoke to a company a couple of years ago, they wanted about £70 to do it. I thought that was a bit steep. You can get a lot of Jubilee clips for £70!

If you use that method, you will need to move it along the prop as well as just revolving it in one place but as suggested try it first.

I had my Series MM prop shaft balanced near Heathrow, not to be confused with a certain engine rebuilding establishment. They did an excellent job and even replaced the yolks as there was play in the UJs

I seriously doubt it will need balancing... It's a relatively small diameter, not very heavy and not spinning all that fast. The polar moment of inertia is really not that high! I suspect many of the props that need 'balancing' are actually slightly bent !
