  1. Your meticulous workmanship in building out these cabins is truly an inspiration, though as I work along constructing the interior in my own marine "dollhouse", I realize that there is still a "long way to go" with improving the level of my workmanship to get even close to this quality. However, your work (and that of others on this site) is inspiring, so onward we go. Thanks for sharing the images and ideas, Craig
  2. A master class on fitting itty bitty parts properly into crazy small spaces. I thoroughly enjoy all of your detailing, especially since I am currently doing interior joinery in TWILIGHT's main cabin. The ideas and techniques you show are very helpful. Best of the Holidays to you. Craig
  3. Hi, Sal: Your model is progressing well and with very nice detailing! I note that you are running the same motor/ESC combination as I have in TWILIGHT. I would heartily recommend -if you have not yet done it - to do the "Transmitter-to-ESC-to-motor" calibration before you get her into the water again. I found out the hard way that missing this step may lead to the motor going full speed on the very first notch of the throttle and the poor boat trying to emulate PT-109. Twilight ended up surging forward nearly out of control and finally rolling onto her port side leading to downflooding. Fortunately, my wife was able to grab TWILIGHT before she sank, but as a result of the swamping, the electronics below deck had to be replaced. ***** (From my post #113 - "TWILIGHT was placed in the water from a local kayak launch ramp after we had first launched Vicky in her canoe to be the "rescue" craft in case of need. When I gave the throttle control on the transmitter a slight nudge to the first detent of forward, TWILIGHT's stern suddenly dropped down in a swirl of bubbles, the bow popped way up, the sudden torque from the prop heeled her over to port and she shot forward, wildly swerving to starboard. This little displacement trawler yacht was trying to emulate PT-109 😲 I jerked the throttle back to neutral while trying to straighten out her course and she coasted to a wobbly stop. Obviously, something was not right and so, I tried to nurse her back around to head to the launch ramp. However the pulses of power, brief as they were, set up a surging oscillation, rolling the model from side to side. I was "behind the curve" with the rudder actions and TWILIGHT ended up broaching to port onto her beam ends and began down-flooding. By the time Vicky could get to TWILIGHT and grab the cabin top, she was awash. TWILIGHT did not sink and was able to be brought to shore to be emptied out with a minimum of exterior damage. The electronics were, unsurprisingly, "toast" and all had to be discarded. It took a number of days to dry out TWILIGHT and I spent some time this discussing the odd throttle behavior with Nick Scalone, of Harbor Models. Ultimately, we were able to focus upon my failure at that time to re-calibrate the transmitter to the electronic speed control unit which governs how much juice to feed the motor. This left the ESC in a default mode and it went instantly to full throttle. (The joys of electric motors.) New replacement components were ordered, installed and, most-importantly, repeatedly bench-tested." With the current now-calibrated replacement electronics, TWILIGHT enjoys a more sedate and controllable speed. ***** If you were smarter than I and have already accomplished the calibration, then please feel free to disregard this suggestion. 😉 <And I second Ian's sound recommendation!> Craig
  4. Well done and wonderfully crisp execution, Paul. Your photos show some fine ideas you are sharing with all of us (for our future projects!). Craig
  5. Welcome back, Michael! 'Tis a delight to once again see you posting.
  6. Thank you for those kind words, KeithAug. As I contemplate the upcoming construction of the interior joinery for the main cabin, you are setting quite a fine example of what I should strive for with your project. Whew!!
  7. We were lucky enough to visit ARGONAUT II some years ago under a previous owner. Her Gardner is a sweet sounding engine. Also, the former Mission hospital ship, COLUMBIA III, running with a gleaming 60+ year old 8L3 Gardner, still works under the careful custodianship of Ross Campbell as a Mothership for kayak trips in the northern BC waters. I believe that Nick is currently cruising as crew with Leo Goolden on TALLY HO making the passage down the Mexican West coast to Panama. It is a surprisingly close bunch of folks who manage to keep these old girls running. TWILIGHT probably would have fit right in.
  8. Thank you, Keith for the compliment. We are both pleased that the model came so close to representing the craft which we had hoped to own. She probably would have been at home in the Pacific Northwest waters, with that Gardner diesel quietly pushing her along.
  9. Hi, Freeks: I used a similar idea of lowered ballast when I built the model of our schooner, MAGIC.
  10. Hi, Freeks You are right and especially so when a vessel is down-sized into a model, giving up much stability that would have been quite adequate if full-sized. Thank you for the thoughts
  11. John: It did that...initially. And then she flopped on her side and my heart felt the same. However, onwards we go. This was much more satisfying.
  12. So, the initial "sea trial" in late October was an "interesting" learning experience. TWILIGHT was placed in the water from a local kayak launch ramp after we had first launched Vicky in her canoe to be the "rescue" craft in case of need. When I gave the throttle control on the transmitter a slight nudge to the first detent of forward, TWILIGHT's stern suddenly dropped down in a swirl of bubbles, the bow popped way up, the sudden torque from the prop heeled her over to port and she shot forward, wildly swerving to starboard. This little displacement trawler yacht was trying to emulate PT-109 😲 I jerked the throttle back to neutral while trying to straighten out her course and she coasted to a wobbly stop. Obviously, something was not right and so, I tried to nurse her back around to head to the launch ramp. However the pulses of power, brief as they were, set up a surging oscillation, rolling the model from side to side. I was "behind the curve" with the rudder actions and TWILIGHT ended up broaching to port onto her beam ends and began down-flooding. By the time Vicky could get to TWILIGHT and grab the cabin top, she was awash. TWILIGHT did not sink and was able to be brought to shore to be emptied out with a minimum of exterior damage. The electronics were, unsurprisingly, "toast" and all had to be discarded. It took a number of days to dry out TWILIGHT and I spent some time this discussing the odd throttle behavior with Nick Scalone, of Harbor Models. Ultimately, we were able to focus upon my failure at that time to re-calibrate the transmitter to the electronic speed control unit which governs how much juice to feed the motor. This left the ESC in a default mode and it went instantly to full throttle. (The joys of electric motors.) New replacement components were ordered, installed and, most-importantly, repeatedly bench-tested. On December 3rd, everything came back together (boat, tides, weather and our schedules) to permit Sea Trial #2. Once again, we launched Vicky in her canoe, did one more pre-launch systems check and then placed TWILIGHT in the water. This time, things went much better. (Photos courtesy of Larry Bender) Though the sea trial was shortened by a strengthening wind, I was able to verify TWILIGHT's basic running gear capabilities (and limitations) through a series of maneuvers. While she is nearly complete topsides, I plan to build out the main cabin joinery modules this winter. The future may also involve removing (2) of the (4) 12 vdc sealed lead batteries and utilizing that weight savings to place a couple of small streamlined lead ballast "pancakes" alongside the keel on the exterior of the hull to provide additional stability when turning. We'll see whether that comes to pass and, if so, whether it turns out to be useful. I must relate that I am truly looking forward to returning to the model shop to make sawdust again after these weeks of wiring and tweaking electrical widgets. Until the next update, my thanks again for checking in on our progress. Craig
  13. Fascinating (and a bit daunting) to see the model's realistic and accurate detailing. You are showing us a fine level of work to serve as an example to shoot for in our own efforts. Well done!
  14. Well done making that prop, Mark. FWIW, we had the 2-blade versions on our boats and they were indeed slippery when feathered. The MaxProp versions we had did require the shaft rotation to change direction in order to completely rotate the blades so that the leading edges were "facing into" the proper orientation for the boat's heading. When one shut down the motor, (and if one was moving through the water sufficiently), the props would then feather into a fore-and-aft configuration for minimum drag. However, those flat blades do give up about 10% in thrust when compared to blades with non-flat sections. Most of the time, that loss of a certain amount of thrust was not a problem. Craig
