Hello,

does anybody make their own hulls from steel plate, or is this considered a no no?

Thanks in advance.

Ben

Vickers, Swan Hunter used to, so did Govan.

"Steel" is a bit heavy for toy boats, but tinplate works well.

Regards Ian.

Sorry Ned, that lost me.

I was thinking of .8 mm sheet. I was thinking such as cos i have some and i like to weld and also anything that gets welded is justification to the financial controller that i needed the welder.

All metal boats are good to go, but a bit beyond my workshop and skills at present.
There's a live steam tug on our pond, ALL metal construction, hull and superstructure, and with live steam plant sails beautifully

Aha so it is not some invisible line that is not be crossed by model boaters. Some fairly hefty compound curves on that tug ,kiwi , looks like i need me an english wheel!

Cheers for all contributions.

Have you decided to do anything yet Ben?
I'm quite interested in building with Aluminium sometime in the future.

Hi Norseman, apologies for the no reply.

I haven't got anywhere as yet. I'm on the slow road to recovery from a significant bout of depression that leads me to be quite sporadic in my interests. Combined with the fact that my workshop was in no state at all, I drifted. I'm currently building a more appropriate workshop and have a renewed vigor for using that sheet of steel! I'll keep you posted.

Thanks Ben

I have an all aluminium sub hull, built by a good mate for me, it was going to be the USS Alligator, and maybe one day it will be.

pictures of my tug, it has a welded steel frame and plates are rivited to frame. malcolm

Goodness Malcolm.........that certainly is a semi scale build construction

....and also a very ingenious application with the windscreen motor for the rudder.....
Just thinking

......you may need some very accurately placed micro switches to limit the rudder arc of travel...........otherwise the massive torque output of the worm & wheel of the drive would rip the structure

before a fuse blew......Derek

malcolm.howard2 · « **Reply #15 on:** October 20, 2013, 02:56:56 pm »

derek the rudder is controlled by a servo that has disc fitted to the output drive, it is made in brass and then cut in 2 pieces to leave space between the 2 halfs this is the dead space so no contact is made to motor. this half has a conection from battery /fuse borde ie + and --. this servo makes contact to a plastic or similar insullated disc that has 2 sprung contactors/wiper blades, this is connected to motor drive arm by a rod, as the motor opperates it pushes or pull the disc to make or brake the circut stopping in the dead band on servo disc. many years ago sail winches used this system it was called the mexico system. the rudder needs this amount of power as it is 12inches by 6 inches or300mm by 150mm 4mm steel plate. malcolm

Looks good Malcolm, what is the over all size of her.....

malcolm.howard2 · « **Reply #17 on:** October 21, 2013, 10:31:53 am »

Hi brian my tug is a 1/12 scale model of moorcock, she is 112inchs long with a beam of 28 inchs. as big as it is, you can still pick it up one at a time. most of its final weight will be ballast

B.B · « **Reply #18 on:** October 21, 2013, 10:58:43 am »

Gee's thats big, so I presume u won't be slipping her in the back seat of the car to pop down to the local creek (pond)when finished,, looking forward to following your progress, all the best with her......

Arrow5 · « **Reply #19 on:** October 21, 2013, 11:25:57 am »

Is it going to be manned like some of the Dutch bootjes ? maybe a watercooled engine would be better ?

Martin (Admin) · « **Reply #20 on:** October 21, 2013, 12:36:15 pm »

Hi Malcolm,

Impressive! Did you take her to Deans marine a few years ago... or was that a different model?

Martin

malcolm.howard2 · « **Reply #21 on:** October 21, 2013, 03:04:49 pm »

Hi Martin yes it is the boat you saw at Peterbough, the photos were taken during the early days of construction it was planed to use my old lawnmower engine (waste not want not, as the old saying goes) but then all the lakes and pond are saying no IC engines because of pollution, at that time i could not find a suitable electric motor to drive the beast, know we have very high powered brushless motors, at last technologie has caught up

malcolm.howard2 · « **Reply #22 on:** October 21, 2013, 03:18:26 pm »

Hi arrow 5 i have two ways to ballast the model i can either pump in a large amount of water or play at being the pilot as sugested i allso tell friends and family that i want a viking funeral where they remove a section of deck slide me in refitt deck and sail me of down our local river out to the north sea malcolm

Martin (Admin) · « **Reply #23 on:** October 21, 2013, 03:47:11 pm »

What motor are you putting in it then?

Photos from 2003...

malcolm.howard2 · « **Reply #24 on:** October 24, 2013, 07:50:47 pm »

Hi Martin i am going green and modern, by going into duel fuel , i shall leave the petol engine as fitted, as the engine has an automatic clutch fitted to it, i can drive the prop shaft via a pulley and v belt with the petrol engine not running , the petrol engine can be removed simply by undoing 4bolts + exhaust clamp, battery power will be the same one i use in my crane barge = truck battery plenty of amps . one other problem was going astern, so electric motor was the simplest solution here, better than constructing a reverse gear box.
