This is a drawing for the construction of the Tap Holder shown in the October Newsletter . The body of the holder is made from Aluminum.
Construction is pretty simple.
The Drill Rod Shaft should be fitted to the hole that is drill and reamed in the body. If you don't have an oversize reamer, try sanding and polishing the drill rod until you can get a good sliding fit. The cross hole toward the front of the body is very necessary if you get a good fit. This hole relieves the air pressure when the body is slid in and out. The body was then sanded lightly to remove burrs.
