Re "It is believed PT-109 was painted a flat, dark green at Noumea, New Caledonia" Just found this- >>The Elco boats came from the factory painted overall "battleship grey." In the Solomons, however, the boats were often moored under or near shoreline trees and vegetation, and the grey color was too conspicuous. No official Pacific camouflage scheme existed at the time I show PT-155, and each crew repainted its own boat during the campaign with whatever materials it could scrounge. To one of PT-155's crewmen, J.M. 'Boats' Newberry, I am obliged for information on the vessel's colors during the campaign for Rendova and New Georgia islands. PT-155 and other boats of Squadron 7 & 9, including PT-109, were simply sprayed overall with a green paint from some local source, probably USMC. The green became lighter when applied, apparently due to the grey undercoat oxides. Over this, PT-155 was painted in random black patches. No standard pattern was used.
Our club is on the list of exhibitors for that show. Although we haven't "officially" been told about it. No matter, I will be attending on, at least, the Friday of the show (as I'm not good in big crowds). Anyone else going, and maybe we could have a little get together ? Here's hoping, Dave W 😊
I purchased a small Proboat Westward 18" sail yacht primarily for my young grandson, who is only two years old. So it looks like I'll being doing most of the training meantime. It's a great little boat and I've popped on a Lego Sailor and Seagull just to give a little humour to the sailing days. I hope to show som of the action in the coming months.
Batteries!, always a problem in the 50s on "paper round" money, used to cadge,"borrow" or steal batteries for our boats.Used to be able to buy a cheap kit and even a cheap Japanese motor (coupled to the prop shaft with bicycle valve tubing) but it would be unused for weeks until I could afford a battery, and then they did not last long.Used to borrow batts from my dads bike lamps,my grannies gas stove lighter and the door bell!.Also use to be able to remove cells from the "winner 120" batteries from my dads sky queen radio as the HV cells used to discharge first.This was the downfall of glowplug motors,we could start them at home but on getting to the pool the tall 1.5v battery would be flat.My dad showed me how to locate good cells on duff car batteries by putting a load on them and measuring the voltage across each cell,we then emptied the acid out into mums washing up bowl and sawed the good cells out,refilling them with acid filtered through a handkerchief!,this worked a treat for starting glow motors but my hankie and the pocket I kept it in suffered!I eventually sorted the power problem by using a clockwork motor removed from the family gramamphone to fit an autochanger.
Yes Paul, with the boat in your picture you are right. BUT it has two props so the tubes and shafts go through the thin hull and have no other protection or support. Like in my twin and multi screw destroyer and cruiser. Also they are supporting bearings for the shaft cos the tubes stop at the hull exits. Here, as Dave rightly pointed out, and I also showed in the pics of my Sea Scout; if the shaft tube is properly fitted in the keel it has all the support it needs and I've never seen internal damage from a 'knock' to a prop shaft!? The fillet from tube to keel does the rest and absorbs any 'knocks'. If you want belt and braces wrap a thin brass strip around the tube just before the prop and epoxy it to the sides of the fillet plate. Which by the way is above and not below the tube! and Neil; keep Paul well away from your models!! 😉 Cheers Doug 😎
Thoughts on carley rafts. Presumably the admiralty would specify that on any ship there should be sufficient boats, rafts etc for the entire crew. Illustrious presumably had about three cutters, whalers and two or three launches. They would between them maybe hold at a push three hundred. A standard size float would hold maybe ten? She would have needed about ninety carleys. In the photo showing the staboard side of the bridge there are about twenty six. There seem to have been carleys hung all over the place, but not ninety or so. Makes one think!
Hi Glyn, I am about to be faced with exactly the same problem with my Sea Scout renovation! After some cogitating (not painful if you do it slowly in an armchair with a decent single malt😉) I propose to make T section frames to fit the openings. Then glue the window into the frame and glue into the boat from the outside. There is a sort of super glue (Glue & Glaze?) that apparently does not show up white on the plastic window! Let us know how you get on.👍 Cheers Doug 😎
Searchlight fitted. I wonder if it was the only one. I have been assuming boats were handled by the aircraft cranes, but that could only apply to those stowed in the bays within reach of said cranes. She must have had some sort of retractable arms that either turned out or were run out. I have come to the conclusion my model will have to be a bit of a hybrid of dates. The best pic I have of her masts, rigging and aerials is of her in the Pacific, with damage to the bridge showing from the kamikaze attack.
and here's another 'Harbour Post' in the wrong section and with no pics! 😲 "Rascal" by oscartrain_ "Graham Bantock "Ragtime" 1mtr yacht. found in a loft, needs finishing." Gents: the 'Harbour' is for presenting complete boats / ships with pics and/or videos to show us what she looks like. The place for new and 'in progress' projects is a Build Blog or one of the relevant Build related forums. Cheers 'disappointed again' 🤔 Doug 😎
Here's a conundrum that I'd like your thoughts on. I recorded some data on one of my boats now running on a couple of the battery packs that were cycled as discussed earlier. They are 6V 5000mAh NiMH packs which, after their final charge, showed they received 5500mAh according to my charger. For the subsequent run I fitted a recorder which showed the current consumption, as on the attached chart; typically 2.55A, with a maximum of 2.9A. A rough consumption calculation based on the chart, of 2.55A for 70 minutes, is a little less than 3000mAh. When I recharged them after the run, the charger showed they'd taken 3850mAh. Why the difference between the 3000mAh consumption, and the replacement charge of 3850mAh? The charge and discharge efficiencies are obviously less than 100%, but this data suggests that the two combined are only 78%. So, for example, if the two efficiences are equal (89%), if the charger states a charged value of 5000mAh, the battery has only accepted 4450mAh (=5000*89/100). When delivering the power, it can only put out 3960mAh.(=4450*89/100). Or in other words, only 78% of a battery's stated capacity is usable. Or is there a different explanation? Roy
You beat me to mentioning this, Doug You are quite correct the Boat Harbour section of the Forum is for members to show their finished models as well as give details of the power set up etc. A picture is really needed to show off the model in all its glory. If you are able to posts in the Build Blog section are very welcome and do produce encouraging and helpful responses from members, who also benefit from seeing how others tackle their builds. There are other specific sections where members can post to share experiences or seek help for specific topics. Some members use Tablets or Mobile devices to view and it could be Stephen may need to make it easier for these users to access the relevant sections and post pictures. All posts are welcome but pictures do add greatly to the impact, and I suggest that any member who has a problem posting, sends Fireboat, Stephen a pm so he can address the issue. happy building and posting Dave
