BMW roundel.

An airhead piston.

A set of hex nuts to hang from the back of your bike, so folks know your bike has a healthy set.

Figure out something you need for your model A/T project.

Driver72 · 01-24-2010, 11:09 AM

1. Take a block of aluminum (or whatever you like) and machine a cube with dimensions of 2.000" x 2.000" plus/minus .001

2. Locate center of each side and bore a 1.000" diameter round hole on each side of the cube to a depth of .500"

Make sure your set-up is rock solid and the soon to created inside cube is well clamped and supported. Good set-up practice...

Finish up with a boring bar set-up to clean up. Hand manipulation of the mill table will be needed.

3. The resulting cube inside of a cube will mess with the average persons mind. Truly fitting a square peg through a round hole.

Don't forget to break all edges and de-burr as required and use all appropriate PPE.

I'd bet he's made a turner's cube already

Yea...probably. One of my first projects...seems like a hundred years ago.

Things are probably easier today.

But he could cast one.

(Model A) That's not a bad idea.. but I just bought a huge batch of parts and can't think of anything else.

A skull shift knob isn't a bad idea, though.

I just recently bought a 100 year old line shaft lathe. The only thing broken on it is an edge of one knob for the cross feed. I was thinking of casting a new one, but I figured I could just machine one out of scrap I have laying around the shop.

That's the dilema. I couldn't think of anything (small) that would be cool to cast, and not easy enough to just machine up in an hour.

P B G · 01-24-2010, 03:23 PM

What about an oil or gas cap for your A?

You might have to machine it to final fit, but you could cast close for the course.

Can you get any detail into the casting with the course foam? Maybe with a soldering iron you could burn something into the cap?

seems like you care enough to take a class only if it "counts" - i.e. took this for a 3rd minor... ;D

btw, what are you going to do after you graduate? maybe make something related to aerospace if you want a job in that field...
