There's a little spring that holds the scale ring in place on the Proxxon MF 70 z-axis. You are NEVER to fiddle with it, or you'll lose it. I lost it. I called the company office in the US, but they don't have it in stock. Does anyone have any suggestions about how I can fix the scale ring in the absence of this spring?
 
I feel your pain! Luckily Proxxon had it in stock when I lost mine. :mad:
It’s a minuscule piece of spring steel. I tried shaping various pieces of metal to no avail and had to wait for them to ship a replacement. Good luck!

I recently made the scale ring obsolete by adding a DRO for the z-axis.

Thanks! A DRO might be the way to go. I'm a little reluctant to drill holes in the housing, but I noticed you glued yours. What kind of glue did you use? CA?
 
Actually, I only glued the caliper head to its bracket as I couldn’t figure out any other way to attach it. For all the other components, I drilled and tapped 3 and 4 mm holes for screws. @Steef66 did glue all his pieces together. I used 2-part 5-minute epoxy and I have no idea what Stephan used. Probably some magic glue that we have no chance of seeing in the US! :eek: ROTF
 
Well, I'm really out of my depth when it comes to drilling metal. What kind of drill, and what kind of bits did you use?

I didn’t use anything special. Standard metric drill bits and taps with my 20v Dewalt hand drill. You can certainly substitute imperial drill bits, taps and screws. All the MF-70 body parts are aluminum so it’s really easy to drill and tap. If you aren’t comfortable with drilling and tapping epoxy glue is a perfectly acceptable option…
Here are some links to what I used.
