  1. Refer to the PDF. There is a short part with photos on how easy it is to do.... after I was shown how. You wouldn't believe the dumb ways I tried.
  2. All gunports cutout and sills (cills) installed. Looks as though I'll need to remove two top timbers for the carronades on the forecastle... but I'll get my final sanding done first.
  3. As we say up here.... now you're cooking with natural gas. Quarter them, draw them and stuff them! 😉
  4. You are doing a wonderful job! Really enjoying your log progress reports.
  5. I use bamboo skewers from the grocery store. If using bamboo shoots I was told to use the middle pith not the bark.
  6. Looks like your off to a good start with your supplies. Here is everything I know about treenails, Trenails, Trenels or Trunnels (a couple images shifted when converted to a PDF but I think you can figure it out) Treenails - Alan O'Neill - 15MAR2022.pdf
  7. Thank you Bruce! The NRJ article in vol 2, issue 1 (1950) by L.H. Harding is an interesting read.
  8. My last posting for this build. An early quadrant. first my inspiration then my finished 3D print. I used a Japanese 50 Yen piece for the weight as it already has a hole in it and I didn't want to deface a coin. The string is eye spliced at both ends, the upper part passes through a hole and flips over the post. The lower is spliced through the coin. The inset images are the sun and the moon. And that's all for this build. Thanks for visiting.
  9. Thanks Canute. Seems our posting were at the same time!
  10. Should also mention that if I used it at night, reading the elevation of the north star (Polaris) from the horizon I would not subtract the angle from 90° as it is exactly the latitude of my location. I printed an early quadrant the other day. Painted it yesterday, and with the temperature feeling like 39°C today I will likely finish it off and post some photos here to close this build off.
  11. Had a nice sunny day yesterday so I tried out my astrolabe. First I set my sundial onto a solid flat board, aligned it to magnetic north which for us is very close to true north and levelled the board. Then I watched and watched and..... Eventually at about 1:17 PM (DST) the shadow was straight under the pointer meaning the sun was pretty darn near directly over head. I took a reading.... 64° subtract that from 90° gives me 26° correct this for the tilt of the earth on 6 Aug 2022 (add 16.57°) gives me 42.57°N.... my latitude well not quite. According to GPS my Latitude is 43° 1' 12" N (43.02°) That is about the accuracy of a mariner's astrolabe. Now to figure my Longitude If I had a clock set to UT or GMT I'd have read the time and it would have been about 5 hours and 17 minutes (5.2837 hours) difference from my reading of 1:17 PM (DST) The earth rotates 15° per hour so 5.2837 x 15 = 79.255° According to GPS my longitude is 79° 15' 18"W or 79.255°
  12. Looks like something I could do alot of damage with😏
  13. I am certain I have this info and can look through my files when I get home later... unless someone else answers before that.
  14. My completed working mariner's astrolabe. Painted and one coat of matte sealer. The $0.15 ballast made a huge difference!
  15. I will be using Kingart Metallic Acrylic - Bronze - paint on my astrolabe
  16. Looks very clean, a place for everything and everything in its place. 👍 I've learnt that whatever you do when cleaning up, ignore all urges to reorganize because you'll never find that special tool once moved.
  17. Good morning Rob. Air brushing is another process I've not attempted. You definitely have the talent for it. Very realistic.
