Comparator
This tool was designed to be used as a height comparator, for measuring recesses and shoulders, checking for flatness and parallelism; small shafts can be checked for straightness with the aid of a pair of v-blocks, it will hold a drop type indicator or a dial test type.
This comparator is no different than any other comparator, the only difference is the adjusting of the indicator, this comparator uses rack and pinion gears to adjust the vertical and horizontal positioning of the indicators which gives the advantage of finer adjustments in both directions. This comparator uses a surface plate that has two ledges, this is so you can adjust the position of the column and then lock it down by the cap screw under the ledge.
Plans for this tool will be available soon
As always thanks for looking and happy machining

Doug, very nicely made and your craftsmanship is outstanding. I now see where you used your straight knurling tool. Nice details. Regards, Paul

Beautiful build with your master craftsmanship Doug. Like Paul said the knurls are beautiful "Good Knurls". Kind of a 2 axis microscope mount, very cool Idea! I bet the backlash on that based your precision gear making is pretty much nil. I might even have to get those plans when they are ready...I see lots of possibilities with it for my plate.
Thanks for sharing with us!! ~PJ
