I spent the day building a Motor control box for my 1955 12.5 Cincinnati lathe. I am nowhere near @holla2040 level on building electronic stuff, but it works perfectly, and I am very pleased.
My helpers spent the day moving our steel rack to an Ajason building, almost killing them. Moving steel really blows. But it freed up half a shop for more toys.
Nice work.
It really makes the lathe so much nicer being able to fine adjust your cutting speed, and or increase it as you do X axis cuts and the diameter gets smaller (facing, parting off). Took mine from 12 speeds (36 - 1800 rpm) to 6 - 2700 rpm.
I presume you have the braking set up?
Up to 1100 RPM on mine, the braking is set at 1.5 seconds, then there is a second stage that will be 3 sec for above 1100.
The braking is linear, so when threading at 20Hz, and say 250 rpm, the stop is almost instant.
Wow man!
I am jelous for sure. That is one sweet set up and that lathe is KILLER!!!
OMG, I have a little Chinesium lathe and a old 1950’ish 10 inch Craftsman that I enjoy, but I have been kicking aroound the idea of getting a “real lathe” for some time.
I am certainly no “machinist” but I do enjoy dabbling and learning about machining.
I hate to be too nosey but, do tell about the particulars…
when, how, where, how long, $,…?
I have $1000 in my VFD upgrade. I suspect that @Bigdaddy2166 is a skosh over that.
Now having done mine, my PM 940M is on the list, but that will be a $2k upgrade since I need to source a 3ph motor, make an adapter for the mount and drive shaft in addition to replacing the electrical enclosure to allow room for the VFD to mount.
My goodness Sticks. This lathe has turned into a BOAT:
Boat= bust out another thousand!
It was in a storage unit owned by an older man who had passed away. I bought the entire unit for chump change. It was filled front to back with machines and tooling. When the guy cut the lock off, he looked at me and said Damn, man.
Boat = Bankruptcy on a trailer…
