Thor

[mike farrellParticipant @mikefarrell21522]

Hi Bob At last got some photos to Paul by Email with the help of my grand daughter. Will be spending the next week at the local Enterprise Unit being taught how to use the computer programmer and laser cutter as I want to do a good job of the windows and top of the superstructure. Run short of 1/32 ply for the skinning of the bows section so will have to wait 5 or 6 days for delivery .

Will search the forum for how to make up a album and then maybe I can post pictures(I live in hope)

John? Not Bluebird, surely? He doesn't do finesse (he's a sand-dancer).
Think what sticks/switches/knobs you'll be using for all this finesse, and then think how easy it's going to be to select the right command when you're towing. That's what's doing my head in!

These photos are of Mikes very impressive version of Thor, Mike has been lucky enough to have help from Elaine, his glamorous assistant and all round font of knowledge.

Well done, Mike

What a complicated structure?…..It'll be a shame to cover it up?

[lnvisiblemanParticipant @lnvisibleman]

Ye Gods !! That puts my handiwork to shame.

What size adze did you use to get such a good finish ?

[Amy jane SeptemberParticipant @amyjaneseptember49770]

Ye Gods ! ! are you still useing an adze?

I've progressed to the scrub cutter!

[Amy jane SeptemberParticipant @amyjaneseptember49770]

Seriously though, that is a very ridged and accurate way to build, nice work all round.

[lnvisiblemanParticipant @lnvisibleman]

A trained beaver may work.

Am I allowed to say that on here ??

Now then all ,I followed Pauls drawings to the letter and any good comments should go to Pauls complicated design.

Picture 1 shown ,the skeleton held by Elaine has no glue holding it together as if followed the design will all hold together with one part as in a jigsaw

when sure of the design I glued all parts.

This is a heavy weight boat -my local metals expert questioned the amount of Lead I ordered (4 stone) until he saw the frame

All but one piece is in 9mm ply .The lower parts of the hull will be skinned in 3mm ply . The upper and superstructer will be in 1/32 ply

The lights wires for the port and starboard are hidden in the hull and in the upper super stricter .It will carry search lights and inner lights

I was going to carry port hole windows but made them (outside frames) too heavy so scrapped them and may start again. Thanks again for your kind comments Michael

[ashley needhamParticipant @ashleyneedham69188]

Mike. Good on yer, buy a truss now, as 4 stone of lead is..well..heavy.

You have room, I would inset some castor wheels underneath, out of sight, and you could pull it along easily then

Invisbleman. No doubt you remember the post someone put in regarding the use of ladies tights for model boats…..

BUT now you mention it, we were casting about for suitable model animals to motorise to go with the Croc and Hippo, and a nice Beaver would hit the spot.

Would have to have the tail slapping up and down of course.

Hi paul. Found the answer to the weight problem at the local lidl stores. An alli trolly with extending base from 400 to 620 mm .The boats fits well but the font of knowledge suggests using straps to keep it secure . Ashley the ballast will come in small ingots so I do not cause injury to self.😊Michel

Hi Paul , It sounds like you determined to do Haydock , that would be great , I was at Southports model boat lake yesterday and there was a guy with a Big Perkasa like mine and we got talking , he was not happy with the prop angle on his it really was very steep . I told him about your idea of mounting the motor up side down to get the prop shaft as low down in the hull as pos , He was gutted he never thought of it so he is reworking it this winter.He as heard of Bobs Brutus but did not know you had designed it . I told him there was a chance Bob would be displaying Brutus on your stand at Haydock ( your health permitting ) . Anyway once again get well soon.

Very Best Regards Dave

[Bob Abell 2Participant @bobabell2]

Hello Dave

Health permitting, Batman and Robin will be having an impressive stand at Haydock this year and we are looking forward to it!

Showing all the models built and talked about over the last 12 months

All are invited to stop and have a chat with us and have their photies taken for the Website thread…..With your permission of course

See you there chaps?

Bob and Paul

Dave…….. A flattish propshaft angle can easily be achieved with Pauls belt layout as designed for Brutus, which is similar to the ABELL drive units

[CookieOldParticipant @cookieold]

Hi Bob , Really looking forward to meeting you and Paul and seeing your fleet . I want to pick Batman and Robins brains about some thing that can,t be put into text i am sure you know what i mean .

Best Regards Dave (The Joker)

[Paul TParticipant @pault84577]

Hi Dave

It will be nice to meet you and we will do our best to answer any questions, cant promise to dress as Batman but Sir Topham Hatt might put in an appearance.

Hi Paul

If you meant my army service, REME that stands for rough engineering made easy, I was RE Royal engineers. That's just a inter corps joke.

Dave

[Paul TParticipant @pault84577]

Hi Dave

The Royal Engineers is a proud and heroic corps which is sadly underrated by the general public. How long did you serve for?

Respect

[mike farrellParticipant @mikefarrell21522]

Hi Paul Now then here is a question which has been playing on my mind recently.

Given the total weight of Thor do you think it would be a good idea to put a metal strap up over the bows?

The skinned weight is 22lbs and will take around 40 lbs of ballast ,take some stopping Michael

[Paul TParticipant @pault84577]

Hi Mike

I was intending to produce a drawing showing a flat steel plate (covered with tyres) on the flat section of the bow that could be used for pushing [and stopping] but a metal strap is an excellent idea and will certainly help prevent damaging the boat.

After Haydock is over I will be able to complete the Thor drawings and instructions and I am sorry to have left you 'hanging' like this.

It has to said that you have taken to this project like a duck to water as the design information that you currently have is basic and I am really looking forward to seeing your progress photos.

Paul

[mike farrellParticipant @mikefarrell21522]

Hi Paul Well after we met at Haydock and picking your brains the problem of controlling the boat being towed has cropped up .

Keeping the tow line straight down the boat has to be addressed. Plenty of room for a fitment?

Enchanted Hammer has had its first coat of paint on the hull and rubbed back to flat ,blemishes found filled and second coat painted today. 2 days drying and will flat back ready for final coat .

Stupid I know but still not established the scale size . 18 or 24 maybe

Changing my super structer to same as yours as at show. Found a pair of handed 65mm props and will fit to 5mm prop shafts

Thinking about your trusters will you be using a winch servo to move them?Michael

[Paul TParticipant @pault84577]

Hi Michael

Re keeping the tow line over the stern I posted this on the Haydock thread.

On the subject titled 'you don't know everything' Gareth pointed out that I had omitted a vital part off Thor, this part is very necessary for towing and keeps the tow line over the stern…….what can I say other than DOH

Until now I hadn't bothered about scale (based upon the principal that it is what it is) but I will have a play on the CAD tomorrow and establish the scale.

As for moving the thrusters I intend to use something like a stepper motor or a motor with a gear box……yes Ashley I know that a servo is a motor with a gear box but I want something with full 360deg rotation. When I have built the thruster equipment I will post the photos.

Paul

[Gareth JonesParticipant @garethjones79649]

Paul,

Just out of curiosity are you planning to control all the pump motors using individual speed controllers or will they all operate simultaneously. I believe, from what you said at the weekend, that all four nozzles will rotate together but I may be wrong. Have you defined a specification for exactly what you want the thrusters to do, in terms of forward, reverse, sideways and turning forces and drawn out the individual nozzle thrust vectors you need to achieve it. I still get the impression that the 'man machine interface' is going to be very complicated.

Gareth

[Dave MilbournParticipant @davemilbourn48782]

Gareth

I asked Paul a similar question about three pages back (or maybe more) but didn't get to the bottom of it. I guess genius can be a little diffident at times.

Just Googled 360° servo and found several. Here's one that might interest you. **LINK**
