Lathe DRO
« on: March 11, 2016, 11:06:03 AM »
For those with WM 250 + copied from my post in another thread.... **LINK**

Not exactly today, more over the weekend; made up a small X axis DRO for my lathe using a cheap digi calliper from Aldi's. The pics show the make up of it, although looking rough & ready I assure you that it was cleaned up somewhat once finished. The block can slide along with the saddle once the 5 mm lock bolt is freed off, when needed the bolt is locked to the underside of the shear & the read head is locked whilst the scale moves with the saddle. As for consistency it has shown to be within .01mm which I find acceptable for what I'm pottering with... not a lot so far...

Using the wiper fixing location, swapped the screw for a 3 mm bolt... the bracket has been soldered onto the scale

Underneath fixing, used metal to metal epoxy resin.

Not pretty but for testing set up ...

Set at zero...

135.91mm useable length

Nothing complicated nor aesthetically perfect but a simple enough job for what I use at the mo' until I can afford some decent kit.
