Jet or Maglev drive?

Possibly 'jet' Martin. ::)

There was a guy experimenting with a motor over on RCG with the prop in an enclosed tube...
http://www.rcgroups.com/forums/showthread.php?t=817889&highlight=36v

Seems to me, it will 'suck' in the bow wave and also 'ram' it in through the front of the pipe as the hull moves forwards. Also, by reducing the exit of the pipe, there should be a 'jet engine' effect... in theory.. possibly.. maybe...

I've made up the main Bitt's.. and sewn / epoxied them to the bulkheads.

Oh I just can't wait to see these zapping across the lake, that's thinking outside the box (or in this case the springer)

This is the beginings of the 'O' and 'J' types from the TBW's.

An "O.J. Springer"

Will it have a big police escort

The tube is to fire out lawyers, right?

The 'O' (Outboard) Type
Its had its bottom added and i have begun to fabricate the 'outboard' steering system..

The 'J' (Jet) Type
Its also had its bottom added and after much cutting and carving, the jet pipe has been inserted through the hull...

Hey toes.

Is the rudder for the jet drive going to be in the pipe?

Over here in Portland

No Andre..

The 'rudder' will be a kort fitted over the end of the jet pipe.

Toes
Just over the Columbia River in Vancouver

Hi Guys.
Thought you might appreciate these pics of Arthur Pickering's new 'Mini-Springer'. It packs quite a punch even for a little 'un as you will see.
Cheers,
Ian.

I will see Arthur this weekend so will ask him for details...........size, motor, batteries etc. might see if I can get some closeup photos too.
Cheers,
Ian.

.. and this is the business end of the setup..

portside II · « **Reply #1214 on:** October 04, 2008, 08:51:13 pm »

now that looks interesting toes, how are you going to apply the drive to the shaft,will this be a direct drive with the shaft set at an angle to the tube as with home made bow thrusters or through a bevel gear .
Cant wait for the next installment

If you look at the right of the pic, you will see a 1/8th flexi

portside II · « **Reply #1216 on:** October 04, 2008, 09:56:44 pm »

Your right Andy ,i have never used a flexi drive never mind seen one up close so i wouldn't have a clue what one looks like .
can they be cut to size or are you limited to pre determined sizes

BobF · « **Reply #1217 on:** October 04, 2008, 11:09:22 pm »

Hi Daz,

You can cut the motor end with a high speed cutting disc in a mini drill.
The cable to motor joint is either a rigid tube with grub screws or a more complicated system that works like a drill chuck.

That system is known as a hex-flex and can be bought from ASTEC Models. It is far better than a standard coupling IMHO. One problem is getting the right sort of flexi cable, (Octura is by far the best) some of the stuff has a high carbon content and unless it is taken out oif the boat, cleaned and oiled after each day's use it will soon go solid and all 'grungy.' I tried some ETTI flexi cable and within 4 weeks it was as stiff as a ramrod and rusted up.
Cheers,
Ian.

You can cut then to size, but with a dremel but very carefully, if it 'blues' (gets too hot) theny it will be a bin job

BobF · « **Reply #1220 on:** October 05, 2008, 12:40:32 pm »

When I first used a flexi shaft it was just after reading an article on use after care etc.
One of the points made, was that if it got hot blued etc. this helped it to NOT unravel after cutting, as the wire lost its tension, but only at the very end.
This was only the opinion of the author and not one against your posting.

Bridkid · « **Reply #1221 on:** October 05, 2008, 07:51:19 pm »

Well Bob,
some folks like to silver solder the end which fits into the coupling and then it won't unravel. The bonus with using the Octura flex cable is that it need never come out of the boat because it won't rust. (That's what Big 'E' told me and he has flexis that have been in his boats for months and months without rusting)

Keep on singin matey!
Cheers,
Ian.

BobF · « **Reply #1222 on:** October 05, 2008, 09:30:04 pm »

Well Ian
If you silver solder the end, wont it get very hot. !!! ??? OR what about it developing a constant bend from being left in and then vibrating badly in use.

I'll keep singin, if you keep looking tall
PS hope you had a great day today
PPS you've already forgotton more about flexies than I'll ever know

PPPS must not hijack this thread. Doh

Bridkid · « **Reply #1223 on:** October 06, 2008, 11:42:04 am »

Hi again.
As promised here are a few more pics of Arthur's mini-springer. The only info I have is that it measures 5" x 2" and is powered by a tiny motor from a DVD player and 4 x 2/3A NiMh cells.
Enjoy the pics.
Cheers,
Ian

PS. Bob, it's only the end 15mm into the coupling that is s/soldered on a flexi shaft.

wow that is even smaller than i thought talk about bath tub sailing if the weather gets that bad he could sail in the sink

.
lovely pics of the sprig and the barges.
