Prop Balancing !

Postby Bigvern » Sat Dec 28, 2013 4:34 pm

Got these propeller balancing rods back from the machine shop yesterday ! Cost was quite high because I only wanted 3 made to see what they would be like. But have spoken to them today and if anyone is interested in purchasing one, I can order a lot larger quantity I would be able to sell them for £13 each + postage which would be a genunie postage cost. (don't know price at this time)
They are made of stainless steal left hand thread one end right hand the other marked black one end for the black prop silver the other.
Any interest please email me at glenedwards@mail.com
Thanks.
Glen.

Brilliant. You win.

Market these to every Phantom owner's group you can find, and you'll have your hands full with orders.

I don't think the photos posted right.

Also I read that it wasn't necessary to balance these props? Was that incorrect?

I've seen them advertised as pre-balanced, but all 4 of the (official) ones I ordered needed at least a little adjustment.

What is considered to be the best method of removing material (weight)
from the heavy side of the propeller?

Static balance is a start, but dynamic balancing would be better?

What is the thread size, perhaps 6mm x 1mm pitch?

A left-handed die only costs about $10, so this could be a
DIY project if there is no reasonable (including shipping)
source.

Getting the right straight, smooth "rails" for the rod to
roll on is the second part of the assembly.

When sanding a propeller to balance it, presumably one wants to
avoid the leading and trailing edges, and also avoid roughening
the "airfoil" surfaces, which could create substantial drag at
higher revolution rates. So, where to remove material?

This looks like a good rod suspension device:

Nope, I have that one, it's small and not worth a darn. The space between the sides is less than 4". This is widely regarded as one of the best options for this type of prop balancing (I bought it and I love it):

Will the P2V prop's center hole fit and center properly on these?

If not, making a new shaft, pointed on both ends, and threaded halfway right-handed
and halfway left-handed should work properly.

I have ordered some to try out, in case nobody else has already tried.
