Fly cutter complete, Scouting materials

I love scouting for materials for making things in the future. While I was looking for the appropriate sized screws at home depot and lowes for my fly cutter,

I snapped a few shots of some interesting things. Like the really low cost ryobi 8" grinding wheel for only 64$ at home depot! I've used the 6" version at the techshop and think it is indeed worth the money. Then of course there is the fellow who parked his toyota truck in classy style (namely on the curb over, and filling two complete parking spots in the middle.) Lastly this 1000 feet of seran wrap was interesting...

Troy and I have been heavily researching, and making serious design decisions about the type of ballscrews, geometry of ballscrews, spindle dimenisions, spindle bearings, dynamic loads for various parts. Grant will do the breakout board once we decide on the stepper holding torque we want. We are feeling 280-425 oz-in. The breakout board we have been looking at is rated for the current of those motors. We just wonder if we could simply pre-upgrade them from the get-go. Basically we are following the "get it right" the first time approach and researching heavily.

Hopefully we will make some more major decisions tommorow.
