X System - Posted: 1 month ago by mactin
hello MBWs A little project im currently working on which may possibly change everything its a non aspirating zero emissions adjacent combustion two stroke submarine propulsion system its self sustaining and its fuel is good old H2O! yes I know you probably think im mental and youre probably right but ive had the test bedder running.

Hi
How does this work?

Response by mactin on the 22nd Mar 2017
Hi Edward, Its a fine balancing act of electrolysis to hydroide gas, compression then ignition but utillising vacuum formation as an assisting force to the power stroke so effectively making it a one stroke which sounds odd.still in development ive tried turbine,oscillator pistons and hydraulic recoil as end movers but the best seems to be the straight reciprocator. Its scary,how the hell can they tax water??? cheers Neil.

Nice engineering, have you looked at straight air tools for gearboxes? plenty of those around in your area perhaps.
Response by mactin on the 20th Jan 2017
U35... Finally done! 2 Months this one took! 3 Ballast Tanks Clockwork Timer for the compressed air system clockwork motor for the coaxial contra rotating tandem props. Maximum time on the bottom 1 hour. clockwork tinplate submarines are great fun!

Nautilus - Posted: 7 months ago by mactin
Hi, not sure if my hobby is of interest but it keeps me happy. I build tinplate clockwork submarines and boats from recycled tins and busted clocks. They sail and dive its a million miles from all the modern stuff but great fun. Have a look at www.mclarenclockworksubmarines.com
cheers neil.

Fascinating to see your work, odds and sods we all through away, would make a fine magazine article for model boats.

Response by mactin on the 9th Oct 2016
hi Mark, I honestly wouldnt know how to go about doing an article but anyone has permission to use any of my site images and commentary. It amazes me just how much gear can be got from stuff people chuck away,im not a mad environmentalist or anything its just that its either dirt cheap or free! really glad you like my stuff.
thanks neil

Incredible models, I particularly like the U34. I would commission one of those just to sit in my desk it's so nice. Well done Rob, they really are superb, thanks for sharing. 👍

Sea Breacher - Posted: 5 years ago by Dave M
Not your typical submarine but certainly an unusual semI submersible. Scratch built by fellow club member Brian Clewes this Is a most striking looking vessel. Fiberglass hull and moulded perspex window. Home built waterjet uses a large 900 (I think) brushed motor, water cooled speed controller and 14.4v LiPo. Looks really spectacular on the water and Brian Is working on the ballast to enable the model to remain just submerged. Video to follow In due course.

Hi Hugh
I do believe Brian used the Graupner water jet unit which had it.s own seals. The model was sold on some time ago so can't check. I will ask Brian when I next see him and update the post. As far as I remember water ingress was not a particular problem.

Response by Hugh on the 15th Mar 2017
Thanks. I am interested in building a RC sub, but am concerned about water entering the hull.

Hi,
I had some special bearings from Francis Fern. This was about 12 years ago and I don't have his contact details. These bearings had a close fitting O ring and needed greasing.
Best of luck
Edward
