If your concerned about your motors, that's the kind of stuff you need. The open area of the larger one is 43% and the super fine about 32% so it will reduce cooling by that percentage but its better than blocking them off altogether. Also it's stainless steel so it's non-magnetic and won't rust like other steel and iron woven mesh.
I was thinking more along the lines of old sock, but OK! :)
Today I cut the aluminium base plate and nearly finished the last few jobs before I screw the hole thing together! Also watched Thor and ripper and their teams on epic win on BBC 1 trying to smash their way out of a caravan but it was an epic fail!!
Been trying to make removable link today but it doesn't want to work , nothing sticks to a deans connector!!!!

Looking good!
They're some hefty bearings!! With the cast iron housings they weigh almost half a kilo each do they not? Suppose it's fine if weight's not a problem, but if your robot's too heavy they'll be a prime candidate for weight reduction.
Overall it's looking rather fine though. Always nice to see another drum :)
have started screwing everything together and hooked up electronics inside the robot. have just had first spin up test of the drum and it worked great! it has a fast spin up time and seems to be well ballanced. also retested the drill motors but found that one at least was flashing inside when i changed directions! i have never noticed it before so thought it was worth asking if this was normal?
Sounds like it's going well! If you're able to get a video online of the spin-up, that would be pretty awesome :)
The flashing inside the drill motors tends to occur more when you change from one direction to the other at high speeds (it also occurs at low speeds, but can be less noticeable). It's just the sudden change of current that causes an electric arc. It's not an ideal life-cycle for the motor, but considering we're using them in robotics and put them through a helluva lot of abuse, they still last for quite a long time.
