+1 Your average encoder does the "squaring up" internally with the encoder pcb.

Heidenhein has made a LOT of encoders and scales...

When I lived in Rochester NY, RGE, the electric supplier would not provide more that 400A single phase service, if you needed more for any reason, 3...

Yes, I have used it in the cnc bridgeport. Made a fixture plate once with 100 holes 5/16-18 it never missed a beat....

[Sparky_NY]

Neither, it sort of resembles a Lovejoy coupling inside, I suppose you could call them keys . There is a spring that keep the "coupling"...

That sounds somewhat similar to the Hardinge TT tapping heads in operation. The TT taping head is extremely simple and wouldn't be hard to build. The...

I think thats a oil level sight glass on the crankcase that you can see in the pic....

[Sparky_NY]

Yes, generally speaking its better to run it on the higher voltage. The current drawn is half on the higher voltage which means the various voltage...

[Sparky_NY]

You are correct, I misspoke. The idea is to see each the outputs at both high and low states, to troubleshoot deeper requires a scope. The digital...

I love it ! The valve on the steam chest is a real nice touch, many will never guess there is a electric motor.

With bandwidth more is better but usually comes with increased cost. For your intents anything 10mhz or up should do the trick. No doubt there are youtube...

[Sparky_NY]

A point of interest.... some encoders have TTL level outputs, others have RS422 line driver outputs. That causes me some grief a few years back. The line...

[Sparky_NY]

Thats funny ! How did you know I was tempted to mention Linuxcnc's halscope?

As long as the encoder is working ok, there is not much to see...

[Sparky_NY]

You can do a quick test with a digital voltmeter. When A is positive, B is at ground and vise versa. Just turn the encoder a bit and monitor the...

I have a TIG and that is a fantastic idea ! I will have to remember that one! Thanks !...

[Sparky_NY]

Agreed, finish and clean up the cnc retrofit or just get another complete lathe. The missing parts will be cost prohibitive to restore it to manual considering...

[Sparky_NY]

A lot of talk of drilling, tapping etc, what makes you think they are not hardened dowel pins? I am going to take a guess you checked.

Now if they could only come up with a way for you to feel 9G's

[Sparky_NY]

Have to say it..... in the first picture, he is lifting the lathe by the chuck/spindle with a chain !!! Bottom line, you NEVER lift a lathe by its spindle...

[Sparky_NY]

It appears you got the lathe back from repairs at Concord. What turned out to be the problem with it? You said "electrical" in a earlier...

Spent nearly all my life in New York state before moving to South Carolina nearly 8 years ago. I can only imagine what it took to get that pistol registered...
