Hi I think only gone and done it ,now both sticks move without the springs ,shame I could not go from left to right !!this is my simple set up large drum is for the job ,small one is the main ….mark

[Martin Field 1Participant @martinfield1]

Seems sorted then.

Of course you could always use more than one set of R/C! 2 Txs round your neck?

Martin

[mark69Participant @mark69]

Hi martin yes so it seems all I have to do now is ,order more parts ,finish the boat ,learn how to sail ,join a club only then can you say " seems sorted then " Ha Ha sounds so simple when I write it down !!!!! As for two tx don't joke we had the top guy from ripmax at our club one weekend he had a plane that needed three guys to fly it ! but it was huge ,I've been giving the woodwork the first few coats of varnish …..mark

[mark69Participant @mark69]

Hi Kimmo welcome along I ve found a ratchet of an old 35 mg 6exa ,in keeping the fit out inside the hull simple just going direct to the sails through pully blocks to the sails ,as this is my first yacht fingers crossed it works !!…..mark

[Martin Field 1Participant @martinfield1]

Mark, how long is your Dragon?

I'm wondering if those little servos will be man enough to control a big sail in a blow.

Mind you, I have no more knowledge of sailing than you. Fortunately I'm making a winch and there are no expensive clubs here TO join. And the one sailing "group" I visited locally a while back was a bunch of four old boys who couldn't have been more unfriendly, speaking only to brag about their cars and how much they spent on their ugly, boring little Isle of Manners.

Clubs? No thanks. I'll do what I always do and get on with it my way in the end.

Cheers,

Martin

Hi Martin those servos are standard size kingmax 6v 6 turn metal geared and rated at 10.63 kg I think they should be OK ?? I could a club near me with a public lake (no fishing) so I'm popping down this weekend if it blowing , tx works fine and I've found another Cap Maquettes in the Netherlands lots cheaper than those south east people ,rude anyway . how's yours did you do your filling ???? ………mark

[Martin Field 1Participant @martinfield1]

Hi Mark,

servos are a mystery to me. I don't know anything about sail winch servos except that they seem very expensive. I guess all you can do is try them and see what they perform like.

With rain on and off, I can't epoxy my Marblehead as the humidity's too high currently and it's too big for my indoor workshop!

Not sure when it'll get done unless we get some unseasonal warmth.

Cheers,

Martin

 

[Martin Field 1Participant @martinfield1]

Well, my dear bride has got me a lovely suit of sails off ebay. They were made by W. Jones of Birkenhead, which is an old name I know, so I am delighted to get some which will look as period as the boat.

No excuse now not to finish it!

Cheers,

Martin

[mark69Participant @mark69]

Hi Martin nice !! You had made some progress ,more than me ! ,Ihade finished the rudder which I mounted before I can lay the deck then something wasn't right about the rudder shape ,so looked over the drawings at work and mine was out of scale and to big so I made another one !! that's put me back a bit now that's the trouble building the real boat you can't make it up oh well at least I noticed at this stage …mark

[Martin Field 1Participant @martinfield1]

Mark, no excuse for inaccuracies when you're sitting on the real thing!

No chance of further progress here in this weather.

Cheers,

Martin

[mark69Participant @mark69]

Hi Martin I've made a heat box with a tube heater inside for when I'm epoxying or varnishing ! Could you not fabricate something similar ? . besides exoxy is different from other resins and unless your in the Arctic it will cure indoors ….mark

[Martin Field 1Participant @martinfield1]

I do the yacht in the shed, which is too big to heat. And a 5 foot heat box would be just another large lump to accommodate. Since epoxy needs 12 degrees and low humidity to go off properly it's best left till Spring I think.

Cheers,

Martin

[mark69Participant @mark69]

Martin don't read those data sheets ! Epoxy will cure once you have added the hardener ,resins like polyester or Vinylester struggle in cold conditions it will be fine ,which epoxy system have you got as some are only realy suitable as a glue where others are for wing skinning ,we use west systems I'm useing an epoxy we got in to try and is way past its use buy date still fine ,rule of thumb ( if it still runny it will still cure)………..shame to let the weather spoil your fun …….mark

[Colin BishopModerator @colinbishop34627]

When working on my 1:1 scale boat it was necessary to do repairs outside in the winter. The key is to kickstart the reaction by gently warming the epoxy (I used to keep the tin at room temperature for several hours beforehand) and also the workpiece – the latter with a hairdryer or similar. This is enough to start the exothermic chemical reaction which will provide its own heat to start the curing process. In a garage you can use a fan heater pointed at the workpiece to keep gentle heat on the work for a while.

[Martin Field 1Participant @martinfield1]

Yes, it WILL go off, but not as reliably or anywhere near so quickly. I use WEST as I did when we restored our boat and cooler weather was a bit of a pain. Once, I had to wait nearly a week before I could re-coat.

And I can't see the point in using glass cloth, except perhaps repairs, which I don't need. I need to get over the shed to do some lathe work, but it's just too cold to stay for long enough to coat a Marblehead! I'm in no rush. Perhaps my Christmas presents of sails and a book all about the lark might move me to get it done in the New Year.

Cheers,

Martin

I took up the challenge of a Marblehead build over the winter months in my 10×8 garden shed/workshop, my power coming from a Black & Decker extension lead out of the patio doors.

Yes it was cold, yes it was cramped, but using a hot glue gun, car body filler & Araldite, I turned an old fibreglass hull, a lump of pine & some old plywood drawer bottoms, into a semi scale yacht that got me some very nice applause from some very experienced boat builders in my local club.

It started as this ……………..

and ended as this …………

[Martin Field 1Participant @martinfield1]

Very nice, Kip. I'm afraid I can't raise that level of enthusiasm when it's so cold. And at 18×12, the shed's too big to heat, despite being completely insulated with 1" styrene sheet (which seems to make no difference beyond draught proofing)

Cheers,

Martin

[mark69Participant @mark69]

Hi all finally made my rudder the right shape 3rd time lucky !! now I can fit it and get on with laying the deck ..mark

[Martin Field 1Participant @martinfield1]

Is that going to be big enough, Mark?

Martin

[mark69Participant @mark69]

Hi Martin what do you mean is it big enough ? it's scale !! can't build a scale yacht with a "cartoon" rudder besides its 10" deep and 3 5/8 wide !..mark

[Martin Field 1Participant @martinfield1]

Well you can, especially if you have to, but ye Gods, I didn't realise it was that big. Should turn on a sixpence!

Martin

[mark69Participant @mark69]

Hi Martin the hull is huge makes me smile everytime I'm working on it, these do turn very fast ,the mast is 1920mm tall and the boom just over 560mm one hell of a sail area !!!!!! ….mark

[Martin Field 1Participant @martinfield1]

I didn't realise it was that big. Bigger even than the Marblehead.

Just as well you have a boatshed to keep it in!

Martin

[mark69Participant @mark69]

Hi I've been busy at work ,we have moved so my build has had to halt for a while ! but now I've been able to get a bit done this weekend ,in this photo I've glued the mahogany covering boards on and cut the teak deck to fit ,before that I've the kingplanks and comings to do !…….mark

[Martin Field 1Participant @martinfield1]

Nice work, but will the deck not be planked?

I had a heart attack on Boxing Day, so model yachts in the freezing cold shed haven't been priority, but my wife dd give me a set of sales for the Marblehead for Christmas.

Cheers,

Martin
