Time's ticking away, and we still have two 'bots under construction. We had some errands to run this morning, but at lunch time we bundled up warm and headed out to the Build Space. There are a number of key things to be done, and with a McMaster delivery last night we ought to be able to make some decent progress. Hit Back after viewing an image.
Speaking of lunch - this is a left-over slice of pizza we made last night - Five cheese and Jalapeno Sausage - very tasty :-)
Some of the parts we received yesterday included some aluminium spacers and a 6mm drill bit, so we drilled out the spacers for the featherweight's weapon motors, to take them up to the 8mm bore of the pinion gears.
Two drill bits and half an hour later and this is as far as we'd gotten drilling holes in the pinion gears. These gears must be hardened, as they're proving to be a bear to work with. We're going to have to think up an alternative method of securing them to the weapon shaft spacers.
Stymied by the featherweight we decided to turn our attention to the other 'bot needng work, our 30lb Sportsman. Here we have the eight saw blades for it. We'd budgeted 4 pounds for them, and they're actually less than one and a quarter pounds, so there's a savings right off the 'bat.
Although we made a good start on the chassis a while back, there's plenty of parts left to be fabricated, and by fabricated we mean drilled and tapped, so it's time to break out the drill bits and take a swing at these weapon shaft mounts.
We were much more accurate in our drilling this time out, and soon it was time to dig out the 1/4"-20 tap and cut some threads.
It took a while, but eventually we had one side done, but as you can see here there's a hair of misalignment in the bushings, so we're going to enlarge the bolt holes a little and see if we can wiggle things into orientation.
We got part-way through the other side, when the cold was a bit much, and it was time to break for dinner. Tomorrow we're going to finish the weapon mounts, and install the drive train. Hopefully on Monday we'll have our weapon motors for the featherweight done, and we can finish installing the internal components.
