    • This is a #1 Morse Taper "B" Mandrel. This is an adjustable pen mandrel that is sturdy, well made (in the USA) with a longer arbor than most mandrels. Most turners want to save time and turn both pen barrels at the same time however, some pen turners know that the shorter the mandrel length the truer it runs. This mandrels allows you to choose the length you require to turn the number of barrels you want. The mandrel is secured in a Type 303 stainless steel arbor using a nylon headed set screw. The tolerances are closely held and you will be surprised how tight the shaft fits the arbor and how accurately this tool works. The mandrel is 7 7/8" long and is long enough to handle any kit currently being sold by any manufacturer. The thumb nut is threaded 1/4"-28 and is interchangeable with the Berea mandrels we sell..
      95% of the pen kit manufacturers us an "A" or 7mm mandrel which is really 6.2mm in diameter. "B" mandrels are referred to as 8mm mandrels but are really 7.2mm in diameter. These are used for the larger pens such as the Cambridge, Churchill, El Grande and others. They use the "B" mandrel because it is more stable and will have a tendency not to flex as much as an "A" mandrel can.
