Here is a picture of my Smithy CB 12220 XL machine. It is well used. I have made a lot of different things with this machine. I know it is not the best machine in the world, but I don't let that stop me. In fact, I really like it.
I have an Anilam Wizard 411 that I bought off eBay from a guy who took it off an Enco 20" milling machine without ever using it.
This is a picture of the scale (or encoder) I mounted on the back of the machine for the travel of the carriage, I have that set as the Y axis. It is nicely out of the way of everything and I forget it is there.
Below is a picture of the cross slide encoder. I also made some standoffs so I can remove this encoder, install the follow rest, then re-install the encoder. (Not that I do that very often.)
Here is a picture of the Z axis scale. The increments on the dial of the spindle are .042", basically worthless. This thing is a godsend, it is right on!
When I first started using this machine, I quickly realized that the dials on the hand wheels are pretty much useless. Then I used a travel dial indicator, but that is a pain to setup, etc. Then I got some long scales like I have for the Z axis and mounted them on the cross slide and carriage where I could read them. But they quickly were ruined by chips and cutting oil and whatever. I start making something and cleanliness is not my strong suit!
The Anilam is like cheating. It is amazing. I am still amazed at how accurate and repeatable and powerful it is. Every once in a while I still discover something it can help me do.
Hope you enjoy the photos!
