Re: pic: Gold VexPro sprocket
This reminds me of 2013. We used a press fit dead axle wheel assembly. To make assembly easier I put the shaft in a freezer and the sprockets on a hot plate, the sprockets would either get slightly lighter or turn a quite off putting green color.
It's worth noting that for aluminum to turn the color your sprocket did it needs to be heated to almost 2000F. Annealing aluminum on the other hand is done below 1000F. Just something to be aware of. -Adrian
