The First CAD model

The project was started before the CNC Bridgeport arrived. The CNC router can cut aluminum really well with sturdy fixturing, mist coolant and light cuts

Spindle, made by hand on the metal lathe. Took all day. This is a hard part to make

Test fixture for developing the spring-applied, electrically released, braking joint

Now that the Bridgeport is in place, machining is a bit easier

The stand is starting to take shape

Somewhat complete. Waiting on Chinese electromagnets

On the glassworking bench. The electrically locking joints don't work yet, so it's being tested with friction joints. Yeah, I know that aluminum against aluminum joints suck and rapidly gall into uselessness, but I need to see if the basic concept is valid

Clamp arm is too short, so make a longer one

The CNC Bridgeport makes it easy

It appears to work, but many weaknesses were observed
