I have had this design of pen buzzing around in my head for a few weeks now so I made both of these today and had to stop bloody super glue orrible stuff it has closed my throat up and doing the photos I noticed I have done one of them wrong so that will go in the bin one black & white and one white & black I started by cutting up 1! strips of all 4 plastics then trued them up and cut then into 5/8" length's with a sledge on the band saw also made a jig to set the bits up in I also stuck a piece of wood on one end to stop break out when drilling I am going to leave them overnight and make the good one up tomorrow
