I currnetly use a Dubro High-point balancer to balance everything I can. Here's my problem. When I put something on it to balance, it seems as though the four wheels incased in the two plactic pieces that turn and allow the main shaft, or the balancing shaft that comes with the balancer, to rotate don't always reflect a true balance condition. My friend at the LHS says to tap on the plastic housing of one side of the balancer with something like a pair of pliers, just hard enough to get the wheels to jump just a little. This will let the balance settle in. He said this is the normal way to use it. When I do this it does seem to affect the balance(makes one side fall), but the consistency of it seems to vary a bit from time to time, especially with the smaller items like the fan. The results are not 100% reproducable and I'm not completely comfortable with them. It's almost as though the wheels in the balancer are not perfectly round. Does anyone else need to tap on their high-point to get it to work correctly? Is there a balancer made that is accurate enough to just work without the tapping? Should I try a different high-point balancer? If so, which one?
I was also thinking of getting one of the magnettic prop balancers for the lighter items. This seems as though this would be very accurate. Don't know which one yet though.
What do you think?

I have to do nothing of the sort with my BuBro balancer. Anything that is put on it settles to the same point everytime, without having to "tap" it. Sounds like you may have a burr on a wheel or inside the plastic housing. I'd box it up and send it to DuBro:

Du-Bro RC
P.O. Box 815
Wauconda, IL 60084


Enclose a friendly letter explaining what the problem is, and if it does it more with any particular way of balancing (i.e.- center or overhang balancing). DuBro has good customer service, and I'm pretty sure they'll take care of you. What you are having to do is definitely not correct.

Balancing

Hi,

You should not need to do anything with tapping it or settling the wheels!

if you need to balance something, and havent got time to wait for dubro to check it over, search for raptorreckers video where he balances his fan using two blocks of ice as supports. maybe you can use just the shaft and cones from the dubro on the ice blocks like he has and get good results?

worth a try if you are stuck.

Cheers

Tim

Thanks guys,

I think I'll be sending it back now for an exchange. Do I need an RMA# to return it, or should I just mail it with an enclosed letter? I've never dealt with them before.

I'm still wondering if the Dubro is just as good as the magnetic free floating balancers for the smaller parts?
