Can't stop adding stuff by RNinMunich Fleet Admiral!   Posted: 4 days ago
Thanks Joe, look forward to that. Been looking at some commercial ones but they're **** expensive and some are too tall to fit in some of my ships. I have several of those small 5V computer fans in my stash, saved from obsolete PCs. I always saved the fans and the PSUs and various cables. The ribbon cables and various connectors can come in very handy, esp. in smaller vessels 😉Also have plastic, alu and brass tubes of various gauges up to 10mm. About to experiment with some small ones for model railways. Will have to build box and fan etc round them. Ciao, Doug 😎 PS No sea trials here either, everything frozen for weeks 🤔

What you need is a box, your nichrome wire a wick from coal oil lamp a small fan from a computer, wrape the wire around the wick put in the oil and the fan will blow the smoke out the stack

Hi Joe, Just happened to be trolling by the computer when it honked! 😁 Glad it was useful, don't forget the Build Blog 😉 Have fun, Doug 😎

Streamline Models by pugwash1 Chief Petty Officer   Posted: 2 months ago
Sorry for not being active for the last few months, I have a little issue with chronic pain. now some say I am a pain in the a## But half hour segments are all I can give to models, lots of stuff on the launching cradles but nothing quite ready for the champagne bottle,"very frustrating" Anyway, I have had a chance to sit at the computer and so far, it looks like you guys are well on the case looking to contact Streamline!! ONETENOR. I hope the blood pressure is under control, it is one of those nasty medical issues that creeps up on you without giving outward signs. I wish you good luck, health and a smile!! looks like you got the closest, with the second link you posted:- https://www.google.co.uk/search?biw=1096&bih=494&ei=HDgKW8ak... Little-Charlie: Did you ever make voice contact? with the link "onetenor" posted? looked like its possibly a distributer (?) but they look like they sell some product under the "streamline" name.

Ship rudders by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Toby, that's exactly why I do not use a 'Dumbphone' for such things. I also have a Samsung so called smartphone, I use it for telephoning (now there's novel) and SMS and occasional snapshots if I don't have a real camera with me. First thing I do with a Smartphone is dump all the the bl***y pre installed Apps that I don't need and just take up memory space or constantly try to 'Call Home' and demand updates😡 As you have discovered; it's the Apps that are smart (or not😲) and NOT the phone itself. Like any computer; 'Rubbish in = Rubbish out'! Before I left UK to work in Germany I worked for a year or so with the then Home Office Radio Regulatory Department and the then 'start up' Vodafone on Acceptance Test systems for the phones and surveying for cell sites. It was pretty clear even then, reading between the operating software lines, where things were going! My first job here in Munich was reprogramming a test system for mobile phones so that it actually did what was needed to simulate the network and prove all functions of the mobiles. Searching for cell sites with two great guys from the Home Office labs was a lot more fun - but the Germans paid better 😁 As you rightly noted 'Ich bin ein Nachteule'! Aber jetzt reicht's mir auch! Gute Nacht, Cheers, Doug 😎

HMS BRAVE BORDERER by jbkiwi Commander   Posted: 2 months ago
Don't know what happened to my last post but I'll try again. This link, https://www.rcgroups.com/forums/showthread.php?1148637-wire-... may be a useful read and explain what I am on about (rough idea in pic). I don't think too many people are aware of some of the problems which can be caused by altering Batt to ESC wiring. I don't think its too much of a problem at lower voltages but see what you think. Not sure if you have a throttle curve facility on your new TX but if it has, using that you can create a gentle start, ramping up steadily, no matter how fast you push the stick up. You can ram the stick up but it will only follow the curve you set. eg pic showing random curve (you can make this any shape you want to control any function) there are usually a number of curves you can set and save for throttle, rudder - anything you want to control automatically. Not sure about your TX but my 9xr even has a feature whereby you can slow the servo action down (I use that on my Piper Super Cub flaps which come down slowly in 2 stages (2 pos switch) and go up faster. Your new TX probably has a lot of these features and once you find how to use them it will open up a whole new world of fun. Another example of what you can do with these computer radios is, on one of my models I am using 'flapperons' to slow it for landing and as the ailerons come down the elevator is mixed to move up to compensate to stop the plane nosing down. It's pretty much endless what you can do. I'm still exploring after 8 yrs of computer radio use. I remember a guy somewhere talking about the flashing lights on his plane and saying it wasn't the lights on a flasher unit it was the TX telling them to flash.

Redundant computer ribbon cables are also a good source, providing many colours. Even the connectors are useful for non essential stuff like lighting. 😎

1-35 Scale Schenllboot By TeeJay by Colin H. Fleet Admiral!   Posted: 3 months ago
Hi there Peter, one book I would like to recommend is the Machineries Handbook it's what I would call the machining bible, it's available on computer disc as well, try your local library they might be able to help. Hope this helps you. Cheers Colin.

Rudders and Propellers by teejay Commander   Posted: 3 months ago
Hi all for the second blog report on the schnellboot I am going to go over the rudder a propeller shaft assembly in more detail. The first stage was to make the rudders which were made of brass ,and having taken note of what has been said about the increase in size needed for the kit by other members I have increased the size of the rudders by 50% so that they have more effect and hopefully the boat will be more agile .I fitted 3mm treaded rod on to the rudder and in a 4mm flanged tube to reinforce the brass rod. The second stage was to make and fit 5mm flanged tube in the location for the rudders in the boat, these were made to be above the water line and will be sealed in place to reduce the possibility of leaks. These were fitted to a rudder platform inside the boat which was fitted to the kit moulding for the rubbing strip that runs the length on the boat and secured by making resin blocks which were fitted with computer extension nuts. which were then superglue in place to secure the rudder platform. The rudders were then fitted in place and held in position with the tiller collars which were made from 8mm rod and fitted the tiller arms and locked in place with 3mm computer screws and ni-lock nuts, a connecting plate was then fitted to connect the three tillers together, I also fitted rubberised washers to seal the rudder tubes. The third stage was to make the propeller supports. The centre support was a direct copy of the kit part made of brass and fitted to the kit with a plate and screws (this plate and the rudder plate were made from galvanised steel) and will sealed with resin after the I test the boat for leaks. The port and starboard supports were made by taking the kit parts and cutting them in have along the joint line or mould seam this gave me a template ,which I used to make cross-section segments but I did alter the template by increasing the boss diameter to 10mm and extending the support legs so that the finished support could be fitted through the hull (the picture of these show the mk1 version where I forgot to allow for the 4mm prop shaft which has a 6mm tube) any way the boss of these segments were drilled out with a 7mm drill and a length of 7mm brass tube fitted through the boss to assemble the segments, all of which were coated in soldering flux at this stage of the assembly which were riveted at both ends to hold it all together during soldering, after soldering the supports were then filed to the size and shape to resemble the kit parts as close as possible and fitted to the hull using a superglue and talcum powder mix and then I cast resin around the extensions to secure the prop supports in place. The fourth stage is the propeller shaft housing for the centre propeller housing I place a brass rod in a plastic straw and place in position in hull and using resin I sealed the hull with the rod in place this gave me a pilot hole for the centre prop shaft after I removed the brass rod. For the port and starboard shafts I used the kit parts which had hole place when assembled, this when I reinforced the housings ,the centre housing I glue 2mm of plasticard on each side and for the port and starboard I made a brass tube shroud which covered the housings which left gaps between the kit part and the brass which was filled by casting resin in the gap this increased the diameter to 10 mm so that there were little chance of breaking throw with the drill and finished these off by fill-in the outside with body filler and sanded to shape and finish . I then drilled through the pilot hole in the housings using very long extended drills and a wheel brace ( if I had use a power drill the heat would have melted the plastic of the kit and may have caused problems) I drill the shaft housings out 6mm them filed them out with 6mm file so that I could insert a length of 6mm brass tube. After all this was done I fitted a flanged bush made from 7mm tube and 2mm brass plate turned to 11mm to the ends or the propeller shaft housings. And now it is time I must ask for some help could anyone advise me on the length of propeller shafts, I know I can use a 300mm shaft for the centre shaft, but port and starboard will have to be longer. and I also need advice on selecting the motors, I want to use 4mm prop shaft with 35mm propellers. Any opinions welcome.

Bending thin plywood by Westquay Fleet Admiral!   Posted: 4 months ago
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

Bending thin plywood by RNinMunich Fleet Admiral!   Posted: 4 months ago
Hi Mike, Suspect that Martin's steam powered computer can't display the thumbs up, so it shows a default square instead. Where the 'green' came from I've no idea! Cheers, Doug 😎

W1 by jbkiwi Commander   Posted: 4 months ago
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 and is removable for access (wheelhouse roof is also removable along with engine cover and foredeck access hatch, - small foredeck hatches open as well.). 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. All cowls rotate. 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.
