Emcoturn 120 lathe retrofit

but since it buzzes, isnt that a sign it is not new either? I bought it as "new in box" now I know its not the right box so maybe its more like "used in a box". can I clean it or something to get rid of the buzz? Or do I not need to worry about the buzz?

worked a little bit on the encoder plate while I wait for more control parts. I cut the hole for the encoder locating bore. Likely I will just do the rest with the manual bridgeport and with a transfer punch, I dont have a mill cutter small enough to do a proper cnc cut and Im wanting to get this done so the old fashioned way will have to do.

got the encoder mount plate finished. It interfered slightly with an ear on the lathe, rather than cut the lathe spindle housing I notched the BEI encoder just enough to give good belt tension. Once mounted it works good, I did remove it again and shorten the screws, the belt drifts in and rides on the spindle plate, but it did this before as well. Doesn't seem to effect anything.

worked on a couple things today. I used one of the many extra cables from the emco to make a new encoder cable. The BEI encoder had a 7 pin military style connector, I found a new mate and soldered the connector and mounted it. I also flipped the wire box on the spindle motor as it was close to the Z-axis stepper travel envelope, now its zero problem. I also figured out a way to turn on the Dell computer from outside the control box. The green button is a standard industrial control butto, (actually a $2 chinese copy) I removed the switch and turned a dowel rod to fit tight in the back of the button. It has a very small travel and with a belt sander I modified the length to just push the on button on the dell at the end of the green button travel. Works very nice.

[strike]You could have unplugged the case button from the MB[/strike]

Actually, looking more carefully, you can't can you?.

no, that was the deal, I would have had to desolder the button leads (SMT) from the motherboard and then solder on wires to make the switch, in the end the mechanical solution was the least painful. I know it looks kinda kluged, but it actually works quite well and it saves me opening the control box every time I start up.
