Tick Tock, Tick Tock

Two build days and two unfinished 'bots. Not much introduction to this one, just get out there and get some construction accomplished. We did start by revising our To Do lists for Formidable Fustigator 2.0 and Palindrome30; unfortunately there seems like about three days of work to do - missing Tuesday and Wednesday evenings has hurt the schedule, but we'll see what we can do. Hit Back after viewing an image.

First up today is another trip to Chris Allison's place for some sawing and lathing. Lots of small, but vital parts.

The bandsaw makes short work of our list of things to cut - some weapon motor spacers, weapon shafts, blade hubs, and transmission shafts.

And over to the lathe for some boring and turning, not just of the pieces we cut, but a pulley and some bushings too.

Here are some blade hubs - these will be drilled and screwed to the blades, and the hubs will be pinned to the weapon shaft.

Not a bad couple of hours of work. We'd like to say Thanks again to Chris for his hospitality and his very cool workshop - incidentally, Chris runs a pretty neat web site with all sorts of cool industrial and machinery stuff for sale.

Back at the Build Space we're drilling the saw blades and hubs. Thankfully these blades didn't put up too much of a fight, unlike the gears the yesterday.

We also had a couple of wheel hubs left to broach, which we just about accomplished, but we broke our 1/8" broach during it, so when we get back from Motorama we'll have to hit eBay for a replacement.

The wheels and hubs have been drilled and tapped for a 1/4"-20 bolt to hook them together, and it's nice to be able to check something else off the To Do list.

We weren't able to line up a welder to stick the gears to some spacers, so we decided to go with a great idea Jason of Team Terror came up with - slot the gear, and put a pin through the shaft to keep it in place. Slotting the gear was easy enough ...

... But drilling the motor shaft was nigh impossible, so we slotted that too! Seemed to work fairly well, with the aluminium spacer in there too.

We've switched the orientation of the shaft on the two motors for the Sportsman, like we did for the Featherweight. We've also pressed on the aluminium spacers for the sprockets, which we'll drill and tap for a small set screw where the Xs are.

Here's the weaponry for the Sportsman - eight saw blades, four for each end of the 'bot, with their hubs installed, and ready to be installed to the shaft.

Now that we have the pinion gears mounted we're able to figure out that the motor mounts need to be one and 1/16" from the center of the transmission shaft, and the bevel gear needs to be 0.3" up from the baseplate, for optimum contact. Once we drill the bushing and mounting holes in the top and bottom plates, we'll be ready to install the transmission, which will just leave wiring on the thirty pounder.

We hit the wall tonight, and decided to go do some laundry and have something to eat, leaving To Do lists with quite a few items on them, but actually a lot of these remaining steps are all dependent on one or two key steps, so if we can get them done tomorrow morning, the rest of the 'bots should fall in place. In reality, we're not 100% sure that both these 'bots will be finished tomorrow ... worst case we'll be doing some wiring in the pits on Friday ...
