Sorry about all this off topic nonsense Neil. My fault.
It really is a nice pen and I might try a couple. I know where there might be a market.
Off topic is fine with me, lifes too short to be serious!
To all those who want to make this kit, measure the tubes before you drill, PSI suggest using a 9/16 and a 12.5mm drill bit???
Sorry but the kits are designed around metric, so lets get the right drill bits, old hobby horse of mine. The 9/16 drill bit is too big, a 36/64 is ideal but you can make do with a 14mm. The 12.5mm should read 31/64. If you use any type of glue and lay the blank down to cure and you have used the prescribed drills you will stand a very good chance of loosing the blank, the first time I made this pen I lost the first eight blanks before I worked out that the drill bits were wrong! The glue will run down the inside of the blank and leave an air gap between wood and tube. Using CA is a non starter as your coverage would be so small that the wood would break off every time without fail.
