Octane Tap Follower
For personal use only, not for resale.
You can download the files here, this is a Heavy Duty 5.750" long Tap Follower. Hold the .500" shank portion or the .750" body. The rear has a center point as well to align the follower if a chuck is not available. The files were too large to upload as one compressed folder.
I was working on a concept Combination Tap Follower/Tap Holder as well. The tip would be interchangeable and allow a tap to be driven using the handle or the hex portion. This would definitely be a fun design and machining challenge.
