After a very busy work week we were looking forward to making some 'bot progress this weekend, and we have a couple of 'bots very close to being done, so we're going to concentrate on those this weekend. First up, the second version of our antweight spinner: Poor Punctuation 2.0. Hit Back after viewing an image.
Last time out we decided that we needed some idlers for the ring, and found some aluminium spacers, pressed the titanium idlers onto them with extreme predjudice on the arbor press, and installed them in the 'bot.
Which caused an issue - the ring terminals are too bulky with the idlers installed, and we didn't want them getting in the way, so we decided to remove them and look at alternative ways of wiring the 'bot.
With all the ring terminals out of the way, we sat for a while trying to figure out whether we could solder the leads together. They didn't all stretch to a common point though ...
