Adjustable & Interchangeable Spindle Square Mill Router Tram Tool 3-6" .5 shank

Description

Out Of Office 7/2-7/4/21 for the 4th of July Holiday Weekend.  All orders will ship the following business day.
Bare Tool
This auction is for the bare tool only and does not include a case or dial indicators.   It is meant for you to supply your own as many machinists already have several AG2 standard dial indicators with a 3/8" stem.  If you are looking for a case or matching indicators we do have those on the Boring Research LLC website at boringresearch.com.
We also carry Metric and Desktop Spindle Square versions as well.
About
We built these as there wasn't square on the market that was universal to different vise sizes or allowed you to change indicators easily or use your own. Currently in the market you find 5" and 3" off center but not a tool which can do both or even a wider range. Also the magnet used for zeroing the square was kept separate. In this case it is held under the main spindle shaft for easy keeping. A nylon washer protects it from chipping.
The spindle square is adjustable with 3/8 holes for 3-6". It can be used to tram on multiple vise sizes, and machines such as your mill, drill press, sine bar and lathe. You can use any indicator with a 3/8 stem so you can install a brand or resolution of your preference. The hardware will never rust and shouldn't damage your indicator unless you over-torque the thumbscrew.
