      Look here too.

      I purchased (well, specified it as a Christmas gift - my wife purchased it) the #PKM-ELC mandrel. It is essentially piece of a 6mm drill rod, threaded to accept a knurled brass nut on the end, and held in a collet chuck on the other end. It also comes with some spacer bushings.

      I haven't used it yet as I am still in the process of moving and setting up the shop.

      It is called a 7mm mandrel because the blank is drilled 7mm and a 7 mm brass tube with a 6mm i.d. is glued in the blank. The the brass tube fits on the mandrel.

        Different pen and pencil kits the bits and pieces are put together for different sized mandels. First thing is pick a style po pen or pencil parts you want and then find out what sized mandel you want. The two sites already given are good.
        here are a couple more.

        You will also need a couple of other items. but you should be able to find the infoamtion in the aboves pages.
        you can download the instuctions and see what size you need. the pen/parts press is handy to have if you are planning to make more than a couple pens.
        but you can use a drill press and blocks of wood with v nothch cut in it or a ve block if you pad the faces.
        Been there, probably broke it, doing that!

          Pen Mandrel / Drill bits

          I have made over a hundered 7mm pen/pencil sets over the years on my 7x 10 grizzly. Use a piece of 1/4 in drill rod thread one end 1/4- 20 then place a nut and washer on it. Center drill the same end. Hold the other end in the chuck . Or better yet a collet. make the bushings from 5/16 drill rod 3/8 -3/4 long. Also MSC carries metric drill bits I like the brad point for wood and parabolic for plastic(Corian). I Bought my first mandrel and bushings from woodcraft then made a couple sets myself. Piece of cake good luck. The tube is actualy a stange size 6.79 mm (.267 in) OD and 6.30 mm (.249 in) ID so you may have to take a little silicon carbide paper or make a lap to bring the drill rod diameter down a couple of thousands.
