Ok, so small update on my progress so far, here is what I'm planning for the X-Axis reader and linear scale: Slotted aluminum plate will allow adjustments of the gib screws: Small angle plate will allow positionning of the reader head stationary with the carriage: Should be able to get...

Had this problem (but much worse) the other day when a 1/2 inch endmill was pulled out of my TTS style tool holder and mangled my vise jaw. The tool you have is for a Clarkson holder and could very possibly be pulled out from a collet. ER40 collets tend to have more holding strength then other...
