  1. Keep an eye on the stocks. When I had a 'real' job, we kept stocks of copper-tungsten. Not really an alloy, but a physical mixture that was sintered. Its function was to provide erosion resistance for electrical contacts. But, I suspect that a good half of it was used to make the bespoke darts that still turn up at the boot sales here.
  2. 1, I blame the parents. 2, That has come up alright. 3, I think the sleeper in the bottom picture is a bit over-scale.
  3. Ah, I see what you mean - I thought you meant the flooring. That's not a common feature outside Ireland - you might be able to scribe some plain sheet..?
  4. Depending upon what it actually looked like, there is the Wills SSMP204 Granite Sets sheet.
  5. It's time the OPW considered this for National Monument status.
  6. Someone should ring Joe Duffy, surely..?
  7. JHB will be moaning about the colour shortly...
  8. We're ready and waiting....
  9. This might be worth keeping an eye on for a few days.
  10. Here we are.
  11. There had been a plan for a transatlantic liner terminal out there, in the late 1800s. That would have generated a lot of passenger traffic.
  12. The recent inspection has revealed few alterations of any interest. The car-parking on a Saturday is only at about 40% of the weekday numbers - and the netting around the water tower has suffered from the weather a bit, although the structure itself doesn't seem to be significantly worse than it was a few years ago.
  13. He's only using the PVA so that she can do his ballasting for him...
  14. There are graphited oils out there which can cause insulation failure issues, They tend to be a darker, more opaque colour than general oils.
  15. I only just got time to start the camera up - luckily it was on the seat next to me at the time. 086 trundling back over the crossing. The power for the gates was not controlled remotely...
  16. Woodland Scenics do four grades of their Hob-E-Lube oils, ranging from the Ultra Lite, almost paraffin, to the Gear Oil, like warm Vaseline. Each with a 'hypodermic' nozzle. The tubes will last your forever.
  17. No Hail Marys will be required for your full absolution, my son.
  18. But, somehow, much more than real...
  19. I think I saw a bit of TV about Blacksod Bay - it might have been Wednesday night, after half eight - probably TG4, but the sound was off. I can't seem to go backwards in their schedule...
  20. Ah, I think you just have to take a run at it, perhaps... I wonder if they might also be concerned that a bridge might be moved sideways where there are expansion joints at the abutments or the possibility that masonry courses could be sheared at mortar planes? There's always the possibility of cumulative issues from multiple strikes passing a damage threshold eventually, maybe. Some bridges do seem to get hit almost monthly now.
  21. Nice. Checking the exif data for those images shows that they have actually been rotated through a total of 360 degrees...
  22. Distances along wiggly lines on maps were generally done with this sort of thing.
  23. A planimeter is for measuring areas. Mine is an Aristo.
  24. Technical Drawing was a specific subject in most secondary schools on the Big Island up into the 1980s. I still have all my old stuff, flexicurves, French curves, stencils, adjustable set square, trammels, Rotring pens, etc. I finally got a planimeter a few years ago - always wanted one...
