Charity shop find.

Sounds good Colin👍 Give us the type names / numbers (for the motor as well), maybe we can find the specs for them (no, not 😁). Be useful to know the dimensions and probable weight of the ship and size of the thruster prop as well. We will bate our breff until you get home.😮 Cheers, Doug 😎

Workshop

"Nifty little lathe,- Proxxon- looks German? " Correct! (Richtig😉) https://www.proxxon.com/en/micromot/24150.php The little milling machine is also Proxxon. https://www.proxxon.com/en/micromot/27110.php There's also now a CNC ready version - There wasn't back then 😭😭 https://www.proxxon.com/en/micromot/27112.php Might invest in the MICRO compound table KT-70/CNC-ready! to upgrade my manual job! They have a range of bigger versions as well https://www.proxxon.com/en/micromot/precision-lathe-and-milling-systems.php Not the cheapest around, but built like the proverbial brick "whatsit" house😉 Google / Ebay around, should be able to find some at reasonable prices. Think I paid around €150 for my little lathe back then. The miller around €90. Happy machining folks, don't forget the 🤓 Cheers, Doug 😎 PS Odd!? Someone else's pics keep creeping in?? A new phenomenon!😐

Motor reversing

Hi All potential submariners! Please consider this before you happily launch your latest creation! You're down at the lake on a nice warm sunny day for a bit of 'messing about in boats'. So far so good. BUT ... before you launch your sub into the deep consider that the water temperature will be considerably less than the air temperature. So what? you might say. This what! To help keep the wet stuff out of the sub and away from your sensitive electronics you need a little over-pressure within the pressure hull (WTC), to keep it WT! Outside in the warm air this will occur naturally. BUT .. as soon as you dunk your sub in the cool wet the air in the hull will also start to cool and reduce the pressure within the hull. This is often enough to create an 'under-pressure' within the hull which can cause ingress of water by literally sucking it in through the drive shaft and control rod glands. Glug glug glug glug😭😭 Time to wish you'd worn your swimming trunks and brought some with you! Solution? 1 Acclimatise your boat on the surface before you sail away and start diving; i.e. let the water cool the hull and contained air before final sealing of the pressure hull and sailing off. 2 Fit a cycle tyre valve and take a cycle pump with you so you can pressurise the hull slightly before sailing. Don't overdo it, one or two pumps should do, or you might blow the sealing glands from the inside 😮😭 3 A rubber (or similar material) membrane fixed into the pressure hull is a useful indicator of over or under pressure within the hull (WTC). 4 Fit a Pressure switch and a Fail-safe device which will automatically surface the boat on loss of radio signal (some RXs can be programmed to do this; i.e. all servos and ESCs go to programmed settings) or on exceeding a preset depth; e.g. 1 metre. Happy sailing / diving / surfacing🤞. Cheers, Doug 😎

Steampunk Pike.

Hi Guys, This log will be more like a slideshow rather than a proper build log as I have no wish to bore you guys to death with all the details. If you have any questions then please contact me and I will gladly answer them. The making of the Pike is a lot easier than you may think but please remember that this is the first prototype and can easily be modified to make what ever you want to make. The photos will tell you most of the story. I was not to fussy about the first skin layer as it is only to give me something to glue to. The rivets were cut down dressmaking pins as surggested to me from members on this site. The eyes were the lenses from some old swimming . I look forward to answering any questions that you may have. Martin.

Brushed to Brushless upgrade

Like I said Rooky, that was before I got my new ! At that distance wasn't so easy to guesstimate how far behind it she was! (Either that or there was a microcosmic black hole hiding in the buoy 😮) Your right! Dad swan was protecting his littl'ns ! https://www.youtube.com/watch?v=oMUlSOaAREM&feature=youtu.be A little later he chased me out into the middle of the lake - but couldn't keep up, PHEW! 😂 Here the performance with a fresh 3S battery. https://www.youtube.com/watch?v=b0BWJ3duzDw&feature=youtu.be BTW: there's a full report on these 'builder's sea trials', with test results using various batteries, in my build blog (Sea Scout - Jessica) and in the Media Gallery I think. How about a blog of what you are up to with yours? 👍 Don't often see Sea Scouts here. Cheers, Doug 😎
