Propeller Balancing

[Louie]

Has anyone used a Buzz Master for Prop balancing? Any thoughts? Looks fairly simple.

Buzz master? I use the same ally plug but line up with the workshop wall brick course:cheezy grin: ! Just being a cheapskate of course

Is there a simple way to balance a 3 blade ground adjustable?

Good-one! Where would I be able to source the plug?

tell me what size and where you live I'll post you one

Much appreciated thank Geoff. Will send you a PM.

Why does the plug have to be alloy?, I use wooden plugs to balance lots of items, (and props)

Alloy is easier (for me) than wood to turn to a good finish ............ My plug is PVC. (2"dia)

I have a Dynavibe....much more accurate and probably faster it also does it dynamically

Static balancing, done well is a good start. If a few basic rules are observed the error will not be enough to give you a problem. You need a place with no wind. Wood is not of uniform density in some cases. Ordinary aluminium bar is not expensive specially as off cuts and lasts a long time. Nev

Im pretty sure most dynamic balancers all say in the manual that you should not dynamically balance until the prop is already statically balanced and the pitch measured in each blade to ensure that a pitch mismatch isn't causing the effectively unbalanced vibrations, which will be difficult if not impossible to balance with adding weight at specific locations across varying speeds

Yes andy..also carbs to be balanced and pitch to be the same on each blade then you can do the dynamic usually at cruise rpm

 

 

[facthunter]

Dynamic is needed when there is a considerable length to the item, because it may balance statically but the weights may have a lot of offset. The common simple prop is not such an item, same as a thin flywheel. Nev.

I just want to try and fly behind something that has significantly less vibration at cruise than 0.1in/sec....people describe such a thing as real smooth and I want to see if its hype or reality :<)

Andy. I found the new 230 prop from Jab to be near perfect for vibration. Also once bolted in, there is no adjustment needed.

 

Plus many other advantages
