Did I say it was green? I wondered what it meant as it appeared on its own. I don't do emoticons, I think they're corny. My "steam" computer is the same as those in my Health centre's consultation rooms, but with a more usable graphics card.....he said like he'd know it from a hole in the arse! I don't possess a mobile' phone, which is why you can usually understand what I type as no mad auto type thing is trying to take over as it does with Klevafones acting as computers. Martin

This is my scratch built 36" RNZAF British Power Boat 64' HSL (arrived in NZ 1940). I actually went on board this vessel in 1968 when it was still in original form (the RNZAF having disposed of it in the 50s) This vessel is still around and has been recently re modelled (2nd time since early 70s) and I was lucky last year to have met the present owner and go on board (2nd time in 49yrs!)and take a few photos. The vessel was modified a number of times by the RNZAF over the years (air intakes, removal of the fore deck machine guns, wheelhouse turret etc so I sort of went in the middle. I found a few drawings of the type in an old mag which had side and top views plus the bulkheads and their positions, so I took them along to a copying shop and kept enlarging them until I had the desired proportions. This worked out quite well and using a few methods from other models I had built, managed to frame (ply) the hull and then fully strip plank it in balsa. It was then fiber glassed. The deck is ply, lined and varnish stained. The wheelhouse is varnished balsa with the top removable for access. The wheelhouse interior has detail such as controls, instrument panels, skipper, steps to wardroom etc but is not too detailed as it is not seen. The boat has full lighting by remote switch, lights are all LED. The propulsion side has dual everything (motors, ESCs, sound units), would have had 3x but ran out of space! Motors are 28mm 2200Kv water jacketed in-runners (cooled by remotely switched pump) using 30A Chinese ESCs (have 5A BEC, Fwd and Rev). Twin sound units are 'GT Power' car units which have around 40 different sound selections, from Cosworths to diesels and are computer programmable (as well as manually on the unit ) for various functions. I am using one of the v8 sounds (8 cyls short in my application) which I think is as near as you are going to get to 3 Napier Sea Lions (for which there is obviously no sound available) They 'start' 'Idle' and are fully proportional in fwd and rev and can sound quite realistic (will attempt to put up a vid later). Batteries are 2x 2200mah 2s 20c LiPos which will last around 2hrs at least of sailing (they also run the sound units) Still have a few small things left to do (have just made wheelhouse air intakes) but don't want to get too fiddly. Just want to keep it a practical model.
That might have been the case before the mobile phone/mini computer boom, Colin, but now they don't learn anything at school, there are no clubs at school and all they want is 'phone games/youtubes of other nerds playing games better than them (yes really!!). They simply cannot see any pleasure or fulfillment in making something and let's face it, apart from racing yachts and very fast raceboats, model boat operation will bore the best of us after 5 minutes! Going round and round with a coaster is limited to say the least. I get my pleasure from making them and almost none from playing with them. Try offering that as an argument to a kid who loves Fortnight or Minecraft. You haven't a chance! Model aircraft or car racing will always take them if there's a hint of interest as those are more exciting, if expensive. Martin
My Cervia was ready built. I have replaced the Electric motor with a large servo motor (Brushed) .Direct drive and being heavy helps with ballasting. lead acid gel cells are power source. Motor rated voltage24 v but run it on 12v . low rev high torque no load current 1 amp. Shaft diameter 0.5 in. Gives some idea of power out. Being servo motor (ex computer drive 30 years old) well balanced no vibration. Photo near shore shows power of motor.
Ed, you have to go into the stored settings for a particular model to save it. From one computer man to another - Anything you do ad hoc while operating is only in volatile RAM and, as usual, is lost as soon as you switch off. A simpler solution might be to just reverse the motor connections! 😁😁 Cheers, Doug 😎
I was just searching for a model car pattern I made months ago for some mods and I found all the lovely etchings I'd done years ago, pre computer, for Riva and Chris-Craft models. These two pics show two brass patterns for the Riva vents and two of the white metal cast vents, one polished about 20 years ago, one done just now, to show that a well burnished casting will stay looking chrome even without lacquer. Then the two Chris Craft tread plates I had the great, good forethought to draw when I found I had a bit of space on the Riva fret. They are perfect, as are the Chris-Craft side flashes and all the Riva badges, even though they were done from hand drawn artwork, proving that Vector images are NOT essential as the pootah people will tell you. I shall mount these two on the typically wedge shaped base and have them cast. I also found a FUEL engraved cap cover which will go on my Chris-Craft filler. It happens to be bang on size wise! I'm cock ahoop! I knew I had these, but had no idea where to start looking. Thanks Mel for getting me started on the search for your Tecno F2 car, but sorry, couldn't find that devil. I have made some more Vincent bits, been to son's to play on his new steering wheel and pedals racing game ( I managed a whole lap of the proper Silverstone in a Lotus 25!) and dined out with the lady wife. What a great day. Martin
yes Doug, and when the computer and printer wont do what you want and your tax return or companies house documents are due urgently but refuse to go through and you tear your hair out and swear violently , you wish life was much simpler ! I thought these machines were supposed to help us. When i was a trainee engineer they told us that in the future we would all have so much leisure time because machines would be doing all the work !!! Got that wrong didnt they !!!
Almost done pistons & rods. I had to revert to threading the rods into the pistons. Had a disaster with silver soldering them. Holding rod in the lathe turning the piston true to the rod. I had upset the temper, both rods snapped. I had no stainless of that size left. Had to turn down larger diameter. I had a home made traveling steady, so very easy. All other photos taken to day lost in computer somewhere. Take more tomorrow.
