  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

Well I've been pretty quiet about things here on the forums lately. I had a few problems with my initial 12z mill, I will not get into any details. But I no longer own that machine.
Also as some of you know, Bill,(wrmiller) has recently upgraded to a knee mill and sold his 12z. After the problems with the first mill I was somewhat reluctant at first. But after much thought I decided that it was no longer a charter oak machine after all of the modifications and re working Bill has done on the machine. So I am proud to announce I am the new owner, unfortunately the Bill said I have to come up with a new name for it. (undecided). But I've been extremely happy with the machine so far. And am proud to call it mine. 9a372a809ab0dd07a872a632f3053dea.jpg

Nice. Congrats. I'm sure Bill made it much better than original which will aid in the fun factor of using it.

Mike.

Long live 'The Boss'! ;)

You can proudly claim that you own a pretty much one-of-a-kind mill. (he's already experienced how powerful this thing is after smoking a couple of end mills...)

You can call it El Hefe, I don't mind. Just don't call it the "Miller Machine Works". ;)

The first project was a combination lathe and mill. A chuck key for a new bison 3 jaw, also courtesy of Bill. 9c27ee1b8a76ea2ccb4114b38ce684cd.jpg d949f96e69dd0b8fbe6a819812623e7c.jpg 36e6869a369611e1be6023105ead5ffd.jpg

Yes this thing is awesome, as Bill mentioned I already smoked an endmill cutting the chuck key 7/16 4 flute hss in 4140 it was going so smooth I decided to take a heavier cut, then things started glowing a dull orange.. oops. All the while the mill never knew it was cutting anything.

Started a new quill stop today. Its made from a chunk of 3x.625 1018. The original quill stop only had 1 bolt holding it in place, a5a211c3a2620b4a3e08f44c171c0ff1.jpg 3e2a231f8b9c1effd5f77e9c777a9d40.jpg 67144a65d665457488e1bd51c7401aa2.jpg I forgot that I do not have a drill chuck yet so I cannot finish it until I get one.

Are you installing a illuminated switch or other indicator that shows power is on? I just put in a order for a LED lit e-stop button, as I keep forgetting to turn off the power to the mill (I changed the VFD fans to temperature controlled in the settings so now I don't even hear those). I'll have to switch from negative to positive and run a return ground for the LED but I think that's it.

Im installing a standalone led, hooked up to a keyed switch. From there it will go out to the e stop switch, and then on to the fwd rev switch. Im installing the key because the mill is at my dads. I dont want just anyone trying to use it while I'm not there.

Is the switch just right of the e-stop your fwd/off/rev switch?

Yep thats fwd n rev. All of the legend plates on automation direct were backwards like the original switch. So i opted for a blank that I could fill in myself.

Yea, I hear you. I had to flip the legend plate on my switch after I re-wired it so I could just write a 'F' and 'R' on there with a marker. :)

Vfd controller mounted, wired, and programmed. The programming was a headache but after a couple hours of reading, head scratching, and cursing before the light bulb moment i got it all working. Only thing I'm curious about is my led lights are very dim. 24v + going to terminal 1 ground to terminal 2. Not sure if I reversed polarity that would make them brighter, or not work at all? The lights are led 22mm units from automation direct.

I think you wired them correctly. They are normally pretty bright. Two posibilities that I can see, maybe you ordered the 120V LEDs by mistake, or your 24V supply is not big enough to power the LEDs. What are you using for a 24V supply?

Pretty sure i ordered 24v leds. But ill check the invoice. The power source is the 500ma 24volt positive logic supply from vfd which is a danfoss fc51

Edit: there are only 2 led's . pwr on indicator, and estop. I can turn one off and the other does not get brighter if that helps
