Home Shop Made Tools

This may not completely qualify as a shop tool, maybe, partially.

Anyways, probably the most recent thing was the backing plate for my rotary table.

On the lathe machining to size.


Turning and facing processes completed and ready to drill the mounting holes.  The step is .001" smaller than the backside of the chuck so it will self center onto the plate.


Chuck test fit onto the plate to ensure self-centering.  I got a little cocky here but I should have test fit it prior to removing it from the lathe.  Had my measurements been off I could have been chucking it back up in the lathe to make a skim cut.  Luckily everything fell together perfectly.  Another reason I probably shouldn't work this late at night.:willy_nil


Vise removed from mill table and the backing plate clamped down locating the center.  I have it spaced off the table so I can drill through without hitting the table.  Using my handy, dandy modified Noga/IndiCol DTI holder.  Works awesome.  You can also see the DRO that I have zero'd after locating center.


Three chuck mounting holes drilled.  The bolt hole circle function in the DRO flat ROCKS!!!


I used a .375" end mill and countersunk for the socket head capscrews to sit just below flush.


Next I flipped the adapter over and plugged the dimensions into the DRO for the four bolt hole pattern to match the slots in the rotary table.


Four bolt pattern drilled and countersunk with a .625" end mill.


Completed sitting on the rotary table.  


Now that my 3-jaw chuck is mounted on my rotary table I can move on to the actual paying job that I needed this for. :dunno:  Oh well, at least it is off my bench and crossed off my list of things to do and is readily available when I have the next job come in requiring the chuck and rotary table.
