Du-Bro Tru-Spin Prop Balancer, Cat No. 499
=================================================
This specialized tool has many positive, excellent reviews for balancing RC airplane and helo blades. but it' cab be useful for balancing other types of blades that move air too. I bought this tool to balance the blades on a small antique (~1930) fan. The stamped steel blades were in good condition but showed some signs of catastrophic damage - meaning the edges of two blades had non-conforming contours close to the hub. Those old steel blades are heavy duty, unlike those on fans manufactured today, so a lot of force would have been required to bend them in that manner.
Anyway, before utilizing this tool, that old fan had to be held down or screwed to my bench or it would have violently bounced to the floor in just a few seconds. And that's after I had aligned the blades with a strobe so they all had the same contour and traveled along the same plane.
This tool allowed me to quickly find the heavy blade so some material could be removed from the end. And to then similarly treat two other blades so all four blades are properly balanced. Now that beautiful old fan is back in service with a new paint job and moving a lot of air - with no vibrations. (Sorry Beach Boys -- When it comes to fans there is no such thing as ♫_good vibrations_♫.)
I know of no other way I could have balanced these blades without this tool. If you need to balance fan or RC blades, I recommend this tool!
Back to the Du-Bro 499 itself. At first I ignored this balance because of some of the negative reviews, and some of the negative reviews are not unfounded. But there are an awful lot of positive reviews also. So when I began to really consider how I'd balance props I had to look at this again because it got the best reviews, overall, and because I'd watched some videos on it. Longer story shorter, I ordered one. I did have a little difficulty putting it together, but was able to get it together and WOW, what a difference balancing makes.
I had some problems getting the last rod into the nut beneath the base, took a good few minutes of fiddling around. I can't tell for sure if the nut insertion spot is a little crooked or if the rod had a little bit too much of a machining problem on the first few threads (in other words, I can't tell if there is actually a problem with the rod or if I messed it up trying to force it into the nut, doesn't really matter). But as I said, got it together and it works great. However, I did call Du-Bro even though it was working perfectly because I was worried about rearranging the balance setup later; because there are different ways to arrange it to work on larger props, etc. Du-Bro immediately sent me two new rods and nuts at their cost. I cannot ask for more. Actually putting it together was very straightforward and easy, except for the last corner rod.
The magnetic balances look OK to me and, in a perfect world one, of them would probably be the way to go (the concept of a magnetic balance is simple, the execution is much more difficult). But it is not a perfect world and this balance is the way to go, at least for me. However, this balance is expensive compared to many others and any balancing is better than none. Balance your props. Do your research. Have fun.
This is a great balancer and does not have the same problems the "other" magnetic balancer has. It can support any size/weight prop, wheel, spinner, hub, and so on where as the magnetic one has a limited diameter and the can only support what the magnets can hold. I was able to test this out with a few props and it is VERY accurate. There is also very little friction in the spinning large wheels so it will work fine on the smaller props. If it is less than 3.5-4", I would recommend using the old string method to balance the object
