HMS BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 1 day ago
The weather has quickly turned colder, giving an excuse to get back to this model. Stripped out much of the interior and the prop. shafts to replace the nylon propellers with brass. These items all needed removing for painting, so decided to paint the hull before reassembly and then moving onto the superstructure. Fortunately, examining similar naval vessels and several U Tube videos, confirmed the hull as light grey, the deck a darker one of the 50 shades of grey and the lower hull below the waterline black. Used thin Tamiya masking tape to define clean colour separations, followed by regular tape, masked the hull into colour sections and sprayed using “rattle” cans. After the colours applied a light overall Matt coat to subdue any shine. The results are satisfactory. Will now reassemble and move onto building the superstructure and the other fittings. Prior to the season closing decided to experiment with my new Flysky Tx/Rx package, shortly to be fitted to this model. This Tx has a servo limiting function, which was hoping could also be used to restrict ESC output. Would like to make the full speed motor response correspond to full Tx control position. Currently can over power the model; which lifts the stern, causing it to come off the plane and then dig the bow in. Was thinking that if full throttle could be set at around 90% forward control movement and 40% sternwards the model would retain adequate performance, but without being overpowered or very sensitive to control lever movement. As the Brave was not available, tried the idea on my Daman Stan 4207 model. This is brushed motor powered and a good performer. Obviously the settings for the Brave will be different, but at least could try to see if the idea would work – it did! This Tx function is easy to use and adjustments can be made whilst the model is on the water. Once the ideal settings are achieved they can be programmed and then retained in the Tx. Will try this on the Brave when back on the water next Spring.

Must get the skins on before I pull all of my hair out!! by MouldBuilder Captain   Posted: 5 days ago
This build is proving to be much more difficult than I had expected. 😤 I think I started this project thinking that all of the parts were ready to fit and glue. As I went on, it became clear that this is not the case. Due to this, and as detailed in the earlier post, I have had to break down the glue joints of the hull frame, and reposition after deepening some of the assembly slots. I have re-assembled the bulkheads, stringers etc. and then started to fit the side skins. This has proven to be the most difficult task so far. You need six arms. After several failures, removal of all of the fixing tape and then starting again, they finally started to look reasonable. I watched a time lapse video on you tube and he seems to do it fairly easily. Oh well. 🤔 Now that I was happy with the fit of the sides, it was time to start on the bottom skins. I started by trying to form chamfers along the keel centre joints so that they look reasonable. Then I once again applied tape to hold them in position whilst glueing with my other three hands, I wish. This only took two attempts. I must be getting better. I still have most of my hair also. Next, I tried to mount the motors onto the angled bulkhead. The front location was very loose so I made a couple of thin silver steel rings to improve the fit. They work very well. 😊 Next job was to fit and align the prop shafts. I decided to make these solid joints and avoid the use of universal joints. The first motor went straight on with perfect shaft alignment. The second was not so good. After two hours of fiddling with a packer, I finally achieved perfect alignment. Next job was to give good joint strength and make the hull water tight. Rightly or wrongly I use a lot of glue to give that perfect seal. I used epoxy for all of the skin inner joints and Stabilit for the outer seams and joints. I used the Stabilit around the shafts as well which looks a little messy at the moment, but I will tidy all of this up next. I will paint the inner Stabilit with white paint to hide a little. This weekend I will do a water test to ensure it is water tight.😱 I think after that I will fit all of the electrics, servo and speed controller. Then I will spray the hull and the main deck prior to fixing together. I would be interested to know what others think about when to paint, before or after assembly, especialy regarding the hull. Enough for now.🤐 I will try to speed up the build a bit now as I am expecting the new 46" Crash Tender to arrive soon. Wood!!! Love it.😊

Here's the yacht after the first coat of red enamel and the keel sprayed with self etch primer ready for the green later, but it's raining, dammit! Martin

Styrene Allergy? by Westquay Fleet Admiral!   Posted: 10 days ago
Where gloves are concerned, use blue nitrile as there are probably more people allergic to latex than styrene! Don't know about you though, but I can't breathe in any mask worth it salt. I just do it all outside in the almost permanent breeze that blows round my bungalow. I stand in the doorway of the shed and spray out into the great blue yonder. Styrene, fortunately doesn't affect me. When Slater's first popularised Plastikard, old man Slater used to demonstrate the making of things like model house window frames with Micro strip and Slater's own solvent called Mek-Pak. The smell was glorious and just oozed quality modelmaking to me. I always made a bee-line to Slater's stand at any suitable exhibition. These days I use Plastic Weld as it does more plastics than just styrene and it doesn't have that lovely "esterish" smell. Martin

Styrene Allergy? by RNinMunich Fleet Admiral!   Posted: 10 days ago
Since Styrene itself is an oil, suspected in some countries of being carcinogenic, used in producing various polyxxx plastics, I strongly suspect the the glue is the source of the problem as you can't be coming into contact with styrene oil itself. So I repeat, good ventilation, extractor fan, thin latex surgical gloves and a face mask as one should also use when spraying. Cheers, Doug 😎 PS Sell that kit and buy something friendlier!😉 https://www.wikiwand.com/en/Styrene

Styrene Allergy? by RNinMunich Fleet Admiral!   Posted: 13 days ago
.... and make sure the working area is well ventilated, an extractor fan helps enormously, as also with spray painting or soldering (esp with the old lead based solders). It's the solvents drying your skin out, removes all the skin oils. Can make your eyes sting as well. 😭 Cheers, Doug

Hull internal finish by J. Barry Petty Officer   Posted: 13 days ago
Having been away from the hobby for a long time, I have a question about the best way to seal the inside of a wooden hull before installation of the electrics. I used to use (all those years ago) banana oil, but I was thinking now more of a spray primer? Any suggestions would be appreciated.

St Canute Planking Help? by Westquay Fleet Admiral!   Posted: 24 days ago
Doug, I don't decant my paint because you have to wait to de-gas it which I ain't got the patience to do. What made you think I did? I used the Rustoleum straight from the rattle can, but it's very thin and you have to watch its tendency to run. The rest is enamel (HRG) bought from the auto paint suppliers and I mix that with a little white spirit and it takes maybe three hours to dry which is fine. Either airbrush (Paasche Model H) or a small spray gun called a spotting or dent gun. Little compressor for the Paasche Model H and bigger one for the spotting gun. Cheers, Martin

Nomenclature... by onetenor Fleet Admiral!   Posted: 28 days ago
Ha Ha i got no credit for some things I came up with either Trouble is I can only remember the word FANTABULOUS which I invented by accident Fantastic and fabulous ame to mind together as I was talking and the hybrid word came out.🤓🤓 Re the BECS I know that but I couldn't explain it like you and was also asking what I thought Martin wanted to know. Floating arrays? Didn't TESLA do something similar during the RC boat . trials? Or was that actually the vessel itself? In one of my bigger boats I used FOUR ex GPO L/A cells which was enough with it's Ex forces motors to put a bone in the boat's teeth as the say. The boat ? RMV Mauritania 5 feet long but very light for it's size hence the need for the accumulator cells Balsa frames and sides with ceiling tile superstructure with balsa bracing. Free running so it was always heeling and with the bone creaming at the forefoot was very impressive. Destroyed by a guy collapsing on it. He'd only fainted but me pore owl gerl was just chips and snowflakes from one end to the other. Nothing to repair as there was nowt left to repair🤐 I kept one cell for starting glow motors and sold the rest at a good profit. Incidentally the motors were that good that when everyone found out where to get them They were sold out in 2 days with no more available anywhere Don't know what they were out of but from the overspray on them ( cockpit green but the Yank version -- we thought) we believed they were from planes. Very solid with 9 segment rotor . Totally enclosed. Airtight? presumably to prevent arcing igniting fumes. The rotorsegments? We found out when one didn't run so we stripped it and found them shining at us. Lovely tight windings. Thick with shellac/varnish. The problem? A stuck brush caused by a tight pivot Drop of 3 in one oil and a very light smear of grease cured it. The carbons were replaceable if you could make or find some. I found a firm in Formby that made and sold brushes for anything. I fixed son's Fiat automatic thenks to them. It had a magnetic clutch and the brushes were so worn we didn't know what the shape should be. Turned out to be about 2 inches long rectangles plain and simple. LOL. Wish I could find some of those lovely engineered motors now.😤👍

HMS BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 29 days ago
Adjusted the transom flaps and reprogrammed the ESCs to the softest start settings, retested. Until now, the test runs did not have the duration or stability to really examine what was happening. Using 3 S batteries acceleration is rapid and a is plane quickly achieved. However, as the acceleration continues and speed increases, the bow digs in. A cloud of spray then surrounds the model as the plane is lost. Brushless motors do not modulate as smoothly as brushed and adjusting power tends to be erratic or exaggerated. This is a scale model and the propeller shaft angles are per the plans. The thrust from the propeller has two components, horizontal and vertical. The horizontal propels the vessel forward. However, the vertical component forces the stern upwards and, correspondingly, the bow down. Have moved as much weight as possible towards the stern to counteract this, limited by maintaining the correct displacement and waterline. The easiest solution is to reduce motor power, decreasing both speed and the lifting component. Decided to retry the 2S batteries as they give reduced power. A plane is again achieved, but as the motor response is more docile, it can be controlled. If the speed gets too high the bow lowers, as before, but the motor output can be more easily adjusted. Spent a pleasant half hour or so with the vessel accelerating onto and off a nice, controllable plane. Much less spray and drama than with 3S and much more controllable. Have now decided to revise plans and use 2S rather than 3 batteries. A further advantage is the motor noise is muted and now sounds more like a gas turbine than a dental drill! Finally feeling comfortable with the model. Will thus shelve further building until the late fall when sailing in Canada concludes. Want to enjoy the rest of my fleet in the meantime! Will summarize my experiences with brushless motors in another blog shortly for the benefits of others contemplating their use. After restarting the model will resurrect periodic build blogs to advise progress.

Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 1 month ago
Evenin' Colin, Thanks for the offer. I'm going to use some stuff the Martin sent me, called Chrodite apparently, although I can't find any description or reference to Chrodite anywhere! Looks like brass with an extra ration of tin. Supposedly harder wearing. Anyway, stator and frame spacers etc are now finished.👍 So after feeding the inner man I'll start measuring up for the bushes and see what I can do about tidying up the drive shafts. Have just sorted out a 'Live Centre' for the mini lathe which should help. I want to hide the bushes inside the original Paxolin cards and the external end plates which contain the felt oiling pad. So ball races are out of the question unfortunately; too large diameter and too thick 🤔 Needle roller bearings would be nice, but I ain't got none that small😭 (Nah, admit it Doug you ain't got none at all, they're way too expensive😭) Amused myself today polishing up all the brass nuts and bolts! Confucius he say "Polishing nuts - very painful" 😁 Weather should be good for spraying tomorrow so I might fire up the compressor and give my PTB a blast of Pacific Green. 😊 Cheers All, Doug 😎 BTW: where are the pics of your Avanti? Harbour posts without pics are pretty dead 🤔 Cheers, Doug 😎 Oops! This doesn't belong here!🤔

Sticking and Spraying by RNinMunich Fleet Admiral!   Posted: 1 month ago
Ain't got no 'Alfords in Germany 😭 But the hull is looking good Neville,👍

Sticking and Spraying by cormorant Fleet Admiral!   Posted: 1 month ago
Good to see someone else is using Halfords shake and rattle. I often use it as a primer/filler and a top coat. Excellent results.

Tamure by jbkiwi Sub-Lieutenant   Posted: 1 month ago
This is a restoration of a launch I was given that was found in a rubbish bin on a farm here in Auckland It is an old RCM ? plan built 'Fairacre' and was pretty rotten when I received it as it is made in balsa and had been wet for quite a while. I stripped it down, re 'planked' large portions of the hull and fiber glassed it, re- built the cabin, re- marked the deck planks, fitted lights, curtains (ex Graupner Commodore bits from the 70s I had kept), stern ladder, cleats etc. It is fitted with a 540 brushed motor (originally had an old Graupner monoperm) and 70s Graupner ESC and Using 2.4 Radio gear. I still have a few things I'd like to do such as a re-wire, fitting chine spray rails, better motor and maybe some safety rails, but for now it does the job.

Brass bashin' Chris Craft deck fittings... by Westquay Fleet Admiral!   Posted: 1 month ago
Just got white metal castings back of the Chris Craft fittings and very nice they are too. They have started to burnish up a treat and will polish well as Paul uses a good quality metal. Nice and hard. Now I have to make the light lenses. Also put the blue bottom on her at the weekend using my one and only pot of Plastikote enamel paint, not the acrylic muck they've turned over to and it went on through my spray gun as smooth as could be. Even my masking worked. Just waiting for a gold pin stripe tape for the boot topping now. The final bit will be masking the deck to paint the covering boards and king plank with the same blue. For those not lucky enough to have a wee pot of proper Plastikote in the paint cupboard, I also got a couple of tins of Rustoleum spray, only 5-25 a pot, enamel (of course) in a nice French blue and a rich cream. These colours will look good on my Darby One Design single stepper "WHO'S DARBY?". Very post War. I think the Oulton Broad One Design single stepper will be Burgundy and the Whippet One Design will be varnished mahogany. I know of no other classes of British stepped hydroplanes. These will all be 1/6th scale as they're all around 12-13 ft. long. I'll probably put the same motors in them eventually. The Darby is well advanced and has a Speed 400, but I may go brushless. Any suggestions for a cheap Brushless/ESC combo will be welcome for, say, 3S Li-Pos. It would be good to see these period boats all racing together. I also plan to make reverse clinker Singer cadet and a Percy See Bugatti engined boat for which I have plans. I'm hoping to get a response from the current keepers of Berylla II about measuring that, too, since it also uses a Lea Francis engine, like the Whippet.
