12z Update And Status After A Year.

maybe you should drink something that calms the nerves and steadies the hand

I am about to go do that. I hear my single-malt calling...

I'm done for the day. Didn't get a far as I expected obviously, but the table is on, the fixed bearing block mounted, and I can turn the screw with a bare hand.

 

[maker of things]

Have one on me. The front of that casting surely would be ideal to mount a plate to reverse the handwheel.

Did you turn it through its full travel to make sure it doesn't bind at the extreme left or right table position? Now you are seeing why I said a few posts ago, take it slow, remain calm lol.

Or just put a power feed on it. Yes I know all you guys scoffed when I put a power feed on my Y but I'm telling you, its awesome.

Now with the ball screws and nuts he could probably turn it with a cordless drill, I seem to recall using a cordless drill when doing my CNC conversion years ago vs hand cranking myself to exhaustion. When you get into these conversions and your putting the table on and off multiple times, yeah poor Bill I know exactly how a guy can get well, upset. lol

I am seriously considering this. There is a floating support plate that can go there for now, and I need to make an adapter/extension so I can at least get a hand wheel on there for now.

I remember.

Now that's a thought. And you are probably right about the cordless drill. When moving the table back and forth I took a small needle nose vise grips and grabbed the end of the screw with it. I was turning the screw with with the vise grips and an index finger. Too cool.

 

[coolidge]

Yeah man put a couple jam nuts on the screw and use your cordless drill and a socket. Don't take any crap off your machine, kick its ass!

The screws aren't machined for your hand wheels?

No, these are the same screws that are machined for the servo couplings (or whatever they are called). I'll have to make a simple sleeve for the X-axis, but will have to make an extension for the Y-axis. Not sure what I have to make yet for the X-axis power feed.

 

[wrmiller]

I know, it's Christmas eve, but I managed to sneak out to the garage and get the adapter made for the X-axis hand wheel. Coolidge: With the gibbs adjusted to right when you start to feel it noticeably drag, the table cranks from end to end with no perceptible increase in effort at the hand wheel. Nada. Sometimes I just get lucky I guess. And the difference in feel now is night and day. Feels like a completely different machine.


I snapped a pic of the underside of the table. It's getting a bit crowded in there, but everything fits.



Have a merry Christmas everyone.

Now you just need to re-name it, the 12z XR71 Miller Turbo Scramjet or something.
