Re: VexPro Bearings

The Emory cloth is absolutely the way to go. Basically, we take off the anodizing on the round part of the thunderhex and it is a nice slip fit.

However, right now since the thunderhex is slightly oversized it is the perfect size for a press fit. We use our small arbor press to get the shaft in the bearings.

With that said, the Thunderhex used with thunderhex bearings is supposed to be a nice slip fit. The bearings are completely within our expected tolerance but the thunderhex stock is a few 10 thousandths large. This is large enough to make it a slight press fit. It is so close that when it is about 30-35 degrees here in Texas the shafts are a slip fit!

In any case, once we run out of the current inventory we will make sure the next batch is within our size requirements at 75deg F.
