Hey man, I was thinking about you this morning. Looks like I'm gonna be moving on the 20th of next month so I get all my gear back from storage. If you need castings of stuff, let me know. I should be ready to start melting aluminum again by the 25th (IMG:style_emoticons/default/wink.gif)

It's a smaller foundry, so about a quart of aluminum is the biggest pour i can do for now.

Hey Jim, there is a much simpler way to find center. Leave the chuck mount bolts loose, bring the spindle down, then use the three jaw chuck and clamp on the spindle. Tighten chuck to table. No indicating required. Usually will get you less than .001 doing it that way.

Incredible skills! I would love one of the Fuchs wheels for a paper weight on my desk. Maybe with a tire on it if possible. Let me know what it would run once you are in production.
Thanks,
Michael

Thanks, Jeff!

It's centered pretty good now. (IMG:style_emoticons/default/smile.gif) the needle hardly moves away from the white line it is pointing at. The chrome socket worked wonders...

and... I didn't want to lose my 'z' setting. it's perfect right now.

Those wheels look great. Is there a waiting list for a full set?

Drew, yes. (IMG:style_emoticons/default/smile.gif) Some have even paid to help cover R&D on the project. (and; Jamie from Japan, and Jeff From CA, have sent tooling and offered up suggestions/advice to help with the learning curve)


The pictures below:

the larger stack are all sliced and squared and ready to be cutdown to size.

to make them look like the other stack. They are all squared up from where the band saw cut crooked. (put them on the lathe for this) after the lathe, they went to the mill because it is set up to run from the computer and it cuts them to size more quickly than I could do by hand on the lathe.

If you have any access to a surface grinder would be a good time to very gently surface grind them to a perfect flat finish on both sides. It makes a better product and setting up in the CNC is a bit easier and they come out much nicer.

Or like another member mentioned....it might be better to make some kind of mold and just pour the molten alloy into it...can you say "INVESTMENT CASTING" ...this is actually an old technique they use to make jewellery with a "lost wax" or wax melting process...not too expensive and easy to machine but you would need a foundry friend who seems to be offering his services.

Jamie, thank you for the tip. (IMG:style_emoticons/default/smile.gif)

I'll probably be getting ahold of rohar on the phone sometime within the next month. He seems to be busy with a move at the moment, and I still need to make a perfect finished product.

It's getting closer each day, and I'm pretty excited about it.

a friend wrote a perl script for me to run a spiral to cut the wheel blanks out. These things are getting easier to cut out and much more efficient.

Now if that solder joint in the spindle speed controller would stop vibrating out...

So pretty. I love watching a mill go. It just makes me happy. A big old bridgeport just came available over here. So tempting...

The 4th axis is back into action!

It was off-center and needed rebuilt.

The collar has two arrays of set screws. the bottom array is for holding the 3 jaw chuck onto the rotary table; the top array is for centering the 3 jaw chuck by finite adjustments to the screws, similar to how a 4 jaw chuck works.

The wheels are getting closer...

The main code is worked out and tested on the 4th axis; the wheel blanks are sitting on deck; and the jigs are built.

I am really making some good progress now. (IMG:style_emoticons/default/smile.gif)

I did some more. I have a stack of about 50 wheels in the making.

Yes sir.

I kept going!

This is the last of the narrow ones being made into blanks.

This is great to see.
Are you ready to start production, or are you still setting the tune for the mill?
