  1. My recommendation next time is to anneal the skirt before forming over the tube or rod. It will be much more malleable and the risk of splitting lower.
  2. The boiler looks rather large for a Jinty. I believe you have one of the GP tanks. I believe this stands for general purpose, they were available in a range of liveries and are rather bulkier overall than a 3F. Michael
  3. Pretty rare I'll agree. The Heinkel 178 and Caproni Campini N.1 (both experimental) were also tail draggers as were Messerschmitt 262 prototypes V1 to V4. The Attacker and the Yak 15 are, to my knowledge, the only operational military jets with this type of undercarriage, both having origins in propeller driven aircraft (Yak 9 for the 15). The Yak 15 was developed in to the 17 which had tricycle undercarriage.
  4. There are a range of solvent-free contact adhesives available, UniBond as an example, and a gentleman I met last year at a local exhibition was demonstrating their use for laminating styrene sheets in building construction. I believe the adhesives are acrylic based, the Selleys brand I use (Australian) is certainly labelled as such. Michael
  5. Understandable, removing material from either could lead to structure weakening at a critical point. Using the etched footplate in conjunction with some of the body castings might be feasible. If not then I know a few N/2mm modellers down here would probably be interested. Thanks Nigel
  6. I'll second that! At risk of dragging the topic sideways, a rummage through the gloat box(es) revealed three Gem kits......I knew of one, suspected two but three! One's a badly built ebay rescue but the others appear untouched. Any suggestions other than back on ebay? Michael
  7. That looks more like Barlow rail to me. https://en.wikipedia.org/wiki/Barlow_rail Michael
  8. Perhaps something a little larger than a Clyde puffer? (not mine unfortunately) Michael
  9. Not too hard really. I made one some time ago to fit on a Unimat 3. It was took an evening to make with all machining done the machine itself, including motor cooling down periods and the fairly gentle cuts needed with steel on these machines to avoid stalling. I made it for Phil Badger who seemed satisfied with its performance. The original MRJ article was in issue 79, Geoff Helliwell describing its construction for his Cowells machine. I really must make one for myself. As that issues long out of print I could send a scan in few days if you're interested. Michael Edit: Colin Bin
  10. Thank you David for responding to my questions. The carbide on styrene was simply something I recall reading without the experience of having tried it. I have a similar memory of someone machining Perspex and using water as a coolant - again I've not tried it. Contributor Bertiedog (I don't know Stephen's last name) has apparently for some time been using 3mm burr-sided milling cutters with success as his post #37 on the 'Lathes & M/C tools' shows. I've used them when grooving a handwheel for a collet drawbar and a clamping knob for a workbench lamp: results were good. I've also milled ur
  11. Chris isn't the only person modelling Newcastle - Ross Balderson is modelling Newcastle circa 1890 in N and making a marvellous job of it. If you've seen his model of Central then you'll know what to expect! Shipping, steam trams etc. Looking forward to seeing Chris's work again, I also totally agree regarding stupid government decisions. Regards Michael
  12. I have been greatly enjoying this topic, not to mention previous ones and your website. Your eye for the finer details and skill in representing them are both fascinating and inspiring. Particularly with the Victory class which I've been taken with since I encountered Don Townsley's drawings 40 odd years ago. It's compact but powerful - a 'pocket Hercules' of a loco with a classic design. Also pleasing is your ready use of machine tools, especially as a Unimat 3 was one of my first serious purchases and still gives great satisfaction. A question in that regard: a little while back in MRJ I
  13. I remember that description too: http://www.clag.org.uk/scrawker.html Colin Binnie who, even if he didn't invent the 'skrawker', certainly made it well known, described how to make them from old hacksaw blades: http://home.iae.nl/users/summer/16mmngm/Articles_htms/ColinBinnie/CBWJ.htm Incidentally, current bi-metal blades are not suitable for re-use in this way. Regards Michael
  14. Something like this should work http://www.ebay.com.au/itm/Walkera-W010-Gear-Pinion-Puller-Remover-Tools-Set-For-RC-Motor-Pinion-Parts-SH-/252497870950?hash=item3aca0bc066:g:QNsAAOSwV0RXrfAO I've goy an earlier version with a fixed lower plate and it works very well. Regards Michael
  15. I've read of a few similar conversions in the Unimat Yahoo group. As well as the circlip fitted to the end and the flat on shaft the gear or belt sprocket is also fitted with a very strong retaining compound/adhesive. Most have had to heat the fitting with a small gas torch to degrade the grip of the adhesive. One fellow however, pointed out that the sprocket was sintered and quite brittle - he rested it on an anvil and used a cold chisel. I have a similar conversion intended for my Unimat 3. which will at least overcome the intermittent duty cycle.
