Doesn't sound like much but I suspect 400 g means quite a lot of holes...

I decided to have a look at the motors today, partly to see if I could measure the coil resistance usefully with my teensy little DMM (was curious about the apparent change to Argos drill motor specs, as discussed in the FW subforum). Unsurprisingly I suppose, the coil resistance was too low to measure on a normal DMM (I might try setting up a 4-wire measurement sometime just to see).

The other reason was to check the motor mounts.

Right side is looking SOLID:

Well done right side.

How about the left side? Left side is...

GOOD GOD LEFT SIDE WHAT HAVE YOU BEEN DOING

So it looks like that's another job to add to the list before RoboDojo...
