Not wishing to drag this extraordinary thread back to an earlier point (says he, about to do just that), I have to convey my thanks for its inspiration and motivation. Without going into detail, I have experienced some of the situational and psychological difficulties Tony and other posters were brave enough to outline recently, with an unhealthy dose of active service-acquired PTSD thrown in for good measure. Nobody without experience could possibly envisage being afraid of something they enjoy doing, but this has been true for me, aided and abetted by the modern 'comfort zone' of viewing, reading about and engaging with the hobby, without ever having to actually indulge beyond acquisition (from scratch, since years of work have been vindictively eradicated, but that's another story).
Last night, I put scalpel to kit wagon floor and scraped. Then I filed. It was good. Given the stunning skills and work on display on this thread, this might appear to be laughably insignificant, but, it represents my first step on a (very weathered-looking) ladder, and the door of Last Chance Saloon slamming shut. If I had not read the foregoing posts, I doubt that scalpel would ever have been wielded again. So, thank you all for your inspiration, and Tony and co., for their bravery.
