Shaft Deflection - can it be changed without changing diamater?

great idea

To investigate further with the shafts, you need a pair of scales.
Use an identical pair of 300 gram .01 increment scales(mainly for epoxy mixing) or something that can measure better than 1 gram.
I make balsa wood v blocks, 1 for tip, 1 for joint, try to keep centre line level.
Place the 2 scales on a level flat surface, tare the scales so the weight of the v blocks is not marring the readings. Read the scales for each end of the shafts.
When the scales are on a level even table/area, the 2 readings will equal the total weight of the shaft.If they do not, then something is out of level or alignment.
This is a crude way of looking at the weight distribution in the shaft, but on a relative bases. See what the tip values are on all the shafts that you have.
That will at least give you some basic info on what you have.

Hi Niel

Great idea. I have a standard postal scale I could use on the joint at a specific arm - and also have a reloading scale that will give me a great idea of shaft front end mass at the tip.

Basically I will be doing an aviation weight and balance calculation on the shaft with any corrections made to reduce front end mass.

Thanks - I think the lightbulb just lit up....

Best regards

Dan
