Dumbo The Flying Elephant

As Jimmy Bridges once said all of the experts don’t live out of town Jim I used a junk cap for an aluminum block bolted down with a reduction sleeve to guide the tap drill and keep in the center. The depth was determined by a mark on the flute of the tap drill. A second cap was drilled the size of the OD of the thread form of the insert tap. Without moving that set up I installed a center in the drill chuck to keep the tap centered while I taped the cap. Both outside ends of the cap were drilled and tapped. After the block was tap drilled I installed the tap guide cap and taped the hole for the inserts. Installed inserts and tested each stud for performance.
I ain’t to good with pictures.
Mr John would be great help.
Hope this helps
