  1. The running part of falls, like the boat falls, were sometime coiled and then wedged between the cleat and the part leading up the davit.
  2. As a minerals policy professional I would slightly diagree with the last statement, though historically you are right. Today, we have mining techniques and strategies that can result in minimal impact. Totally impact-free, of course, is not possible.
  3. ... you had a complete building log on www.shipmodels.info, if I remember correctly. And yes, that is what I am doing for simulating wet sand, to play with acrylic gel and gloss acrylic varnish on fine-grained sand. I was too lazy to go back to the beginning of the building log to check and wonder, whether loaded the whole dredged material into the barges, or whether there has been some kind of sorting on the (bucket?) dredger? I wouldn't want to know about the impact on the river flora and fauna of the dreging and the release of the tailings though ... The water must have been turbid for miles down the river.
  4. Wow ... all that with hand-filing, while I struggle to do such things with my machines ... 👋🏻
  5. I was actually thinking of the springs under the seat of the buckboard …
  6. Without shock-absorbers/dampeners they must have been swaying a lot ...
  7. Another thing to look for are toolmaker or watchmaker drill-bits with a thicker shaft, below 1 mm they have a 1 mm shaft and the spiral part is much shorter and therefore stiffer than drill-bits with full-length spirals and uniform diameter. They are HSS and not to be confused with those brittle carbide drills that seem to be ubiquitous now and have either 3 mm or 1/8" shafts.
  8. I think such cross-braces were also used sometimes in full-scale practice ... Looking at the above photograph, I have the feeling that the cant-frames are too much in and also may not be full enough. Could be a question of perspective though. Did you check against the rail- and deck-profile? It would also be useful to run a batten along the frames to the stem-post, horizontally and diagonal - it would indicate kinks and forced runs.
  9. Well, barely a month into project and I already almost missed it completely ... You didn't describe, how you went about the sculpting of the decorations, didn't you?
  10. It's all about finding the right configurations and writing the right specifications. Such experiments even date back to the Boer Wars in South Africa, where they began to armour traction engines, if I am not mistaken. It's also about understanding the tactical possibilities and thinking beyond the then current engineering capabilities. It is clear that initially tanks were mainly conceived as infantry support vehicles, rather than a replacement of heavy cavalry (light cavalary in its reconnaisance role began to be replaced by armourd road vehicles). It wasn't until the late 1920s/early 1930s that IC engine and track engineering made fast tanks really possible. Until then tanks were seen as war-elephants, rather than chariots, hence the idea of converting crawler tractors.
  11. It may be worthwhile browsing some on-line tool sellers and then go to this shop with the knowledge gathered. Naming the tools in Spanish though is another story. Perhaps you can take screen-shots and show this to the staff. I admire the shipwrights (of old) for their capability to shape such complex non-Carthesian objects. I know from my own experience that this even more difficult in small scales.
  12. I like this solid construction of metal-sheathing around a metal framework. I would have probably chickened out and built such things around a wooden core.
