Bob. I think that if you are not too bothered about absolute very low speed control, and dont have a juicy motor so are not worried about the relative inefficiency of these things, why not use up what you have?

Were they reliable?? It seems that ESC`s dont last forever.. I dont see why a Bobs board should not last ALMOST forever, at modest motor current drain.

Hello Bob ,

Recieved ESC this morning , thank you very much Larry……

HI Ashley , ……..have illustrios on the drawing board will keep you posted …..Larry…

[Bob Abell 2Participant @bobabell2]

The kit rudder can not be removed once assembled, which is not to my liking!

Made a Becker rudder instead, just for a bit of interest and it`s nice to show to the club members

Also modified the bottom bracket, to something more substantial

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hello Bob ,

thats a very interesting rudder , is there working drawing any where <?, …Larry…

[Bob Abell 2Participant @bobabell2]

Thank you, Larry

I'll post a few sketches shortly, with a few improvements of course

Bob

[Bob Abell 2Participant @bobabell2]

Hello Larry

Here is the CAD drawing of my Great Eastern Becker rudder

And a clear photo of same…….Pick the bones out of that!

Bob

[Bob Abell 2Participant @bobabell2]

A thought has just struck me!

Will a Becker rudder work on a paddleboat?…….ie…….No prop wash!

Too late now

Bob

[DuckyParticipant @ducky]

Hi Bob

The water passing over the rudder is what counts isn't it, might not be as good as with a prop but should still work shouldn't it, there again what do I know, I'm only the ships mate!.

Duckie

[DuckyParticipant @ducky]

Just thought Bob, rudder works on your yacht (even if you don't have the prop turning) so there you go!.

Duckie

[Bob Abell 2Participant @bobabell2]

Thanks Duckie

I should have realised that myself!

Like I said…..Too late now!

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hi Bob,

Thank you for drawing nice and clear now ………Larry….

[ashley needhamParticipant @ashleyneedham69188]

But , the question should be… how much, if at all, better does it work with no prop-wash?

Arguably (just to play devils advocate) an extra large rudder would work fine on a paddler, just as well as a smaller fancy rudder and for little or no extra effort?

Ashley bob, that looks much better in brass!!

[Bob Abell 2Participant @bobabell2]

Ashley

In the first place, I ain't got no brass, but in plastic, it suits the model build?

Later on, I may remake the rudder in brass

When sea trials arrive, the Becker feature can be removed quite easily

Bob

[Paul TParticipant @pault84577]

Hello Bob

Nice engineering work on the rudder and up to your usual standard but have you used some ferrous metals in the construction.

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

What a strange question?

I suspect a trap somewhere!

Lucky for me, the rudder post is stainless steel and the Becker hinge pin in made from brass

Now what?

Bob

[Paul TParticipant @pault84577]

Hello Bob

Your suspicions are unfounded as I simply wondered about your choice of materials. Knowing how you work I was confident that the tube and shafts would be stainless or brass.

I am more interested in the smaller components such as nuts and grub screws and wondered if you managed to locate a supplier of non-ferrous parts.

Paul

[Bob Abell 2Participant @bobabell2]

A thousand humble apologies, Paul, for for my uncalledfor suspicious behaviour!

Got to confess, the 6ba nuts and bolts are all steel!

I could make my own brass nuts and bolts, out of brass, I suppose……..If it was really necessary

Although building this mainly plastic kit is a little frustrating at times, I am pleased to be building something again!

Bob

[Paul TParticipant @pault84577]

Bob

No apologies needed as I can appreciate my oblique style of posting can be annoying.

I had hoped that you had found the holy grail of non ferrous fixings.

I am intrigued as to why the plastic kit is frustrating a model builder of your calibre.

Paul

[Bob Abell 2Participant @bobabell2]

The frustrating part of the build, is the wibbly wobbly state of the vacuum formed mouldings!

They are so feeble and the draw angles are not a pretty sight either!

Fit for purpose, I suppose?

Bob

[Paul TParticipant @pault84577]

So would you build another kit?

[Colin BishopModerator @colinbishop34627]

Paul,

Kits are frequently frustrating to people who normally scratchbuild as you always think you could have done a better job/used a different technique etc. yourself. And this is frequently true as the manufacturers have to compromise to make their products a viable commercial proposition. The use of white metal stanchions and soft brass wire is a case in point, as are the frequently supplied white metal rudders and props….

Colin

[Bob Abell 2Participant @bobabell2]

Quite true Colin

White metal fittings in great numbers are another source of frustration, as they are so heavy……Especially topside!

Paul…….I am sort of enjoying the build as all the bits and pieces are in one box and is easy to make progress, and making a few improvements here and there is very satisfying

But don't fancy another plastic based kit…….. might like the plywood Fairy Huntsman with all the old Slo Mo gear in?

Bob

[Bob Abell 2Participant @bobabell2]

I`ve been asked the reason for the brass boss at the bottom of the plastic Becker rudder

Had the constuction been of brass, then the rudder would have been soldered to the rudder shaft.

But since it`s plastic, I have filed a slot across the top face of the brass boss and the rudder just sits in it. The screw provides the drive from the rudder shaft

Bob

[Bob Abell 2Participant @bobabell2]

Glueing the paddlebox decks in place called for some nail biting alignment, but thanks to the odd angled supports underneath, the imaginary problems disappeared!

What a pleasant relief?

Taking shape now…….Bob

[DuckyParticipant @ducky]

I think we all have those imaginary problems and think about them and put them off by doing something else on the build, then find you have to do them to progress. But you've usually given it that much thought that as you say they've disapeared, so have worried for nothing!.

Join the club Bob!

Duckie.
