Very nice, Ed - both of 'em! And those woods look brill! Well done!
Re the shorter version - I've often made an under-length Euro due to something going wrong during the turning. etc. So long as you have enough upper barrel for the top end of the refill to fit inside then you can make them as short as you want. At a push you can make the pen even shorter by removing the plastic seal on the refill as well, but only as a last resort, LOL! As I'm sure you'll know already!
