TALACRE my build
« on: May 01, 2013, 07:56:21 PM »


Today I started the build of Caldercraft's  Talacre.  This is a single hatch coaster named after the town of Talacre in Wales.

The kit is complete in the box and has not been started since it was bought some years ago, so we are dealing with instructions written the old way.

Here is the box with all the contents laid out ready to put together and I should like to show how I did it, warts and all.  I may have a few questions as we go along.   %)

I have cleaned out the hull and drilled the first holes. I then fitted the 4mm prop shaft and made a block to secure the motor. I have chosen a 500 type motor and tested it for quiet running.

The assembly was lined up and epoxied into place.

The rudder was next to be lined up and the supplied parts were slotted in and fitted great.  I have not epoxied these yet as I find it best to leave until the linkages are set up.

The propeller was a cheap cast affair and was discarded in favour of a brass one 5 mm larger as we are not going for speed so much as power when sailing her.

Thank you for supplying her to me, Mike,  I'll try and make you proud of me.    :}

Cheers

Today I went through all the wood sections and cut out all the little pieces (not forgetting to renumber them on the backs)

The decks were laid inside to get a feel for the fit and it was decided not to use the supplied Balsa wood design. I plan to fit a sturdier frame around the insides of the bulwarks.

As an addendham, this model was notorious for having a Kink in hull sides left over from the original moulding at the factory ????    This was attended too some weeks earlier when I clamped wood to the sides and left it tightened together up in the loft.  This idea worked and now the sides are straight and true.

Cheers for now

Ken,
 
I think the kit still has the bridge the wrong way round - see photo.
 
The painting is wrong too!
 
Also, I did the original review for Model Boats - I can email you a copy if you want.

I'm sure you will do her more proud than I would have Kenny.

Yes please Colin.  I seem to recall reading it in the mag but don't know where it is now.

Good job you wrote quickly, as I have cut the Bridge parts out and was sizing them up against the hull to get their positions, and thought at the time it looked wrong.  :o

Good job I've left the two deck half's over length. Now I can position the bridge wall more accurately.  I'm working on the deck curvature at the moment.  (cutting the curved under braces)

Cheers

Please click on my name in the profile on the left and it's there.

Cheers

The inside rails have been epoxied over night and here's the result.

On the Talacre, the two decks are at different heights. To this end we have made two decks and fitted curved braces underneath to get the deck to curve throughout their lengths.

These have been placed inside the hull and you will notice that the sides have splayed out somewhat  !!

Hopefully, with the aid of elastic bands they will pull together when the time comes for securing them in.

It is time to fit the rudder servo.  Unfortunately the rudder shaft only protrudes half an inch above the rudder tube which in itself only comes up a short distance inside the hull.  The rest of day was spent pondering the problem. 

The tiller arm was missing from the kit so our came the faithful 13 amp plug pin. This proved to have a very large hole in the end and was too big for the spindle which was only 2.5mm.  Also, when in position it proved to be too low as it knocked the stern rise of the hull.

It looks as if a re-design will be necessary as I need more height to the shaft inside the boat. I need to fit an extra length to get it higher. I need to make an inline coupler  to fit an extra bit.   Hey ho ... that's what this hobby is all about.   :}

Cheers for now

Ken

Why not trim the top of the white metal brace.Redrill the 13 amp plug leg to the correct size and then drill though the shaft and plug thingy and either split pin it or use a peice of brass rod thru it to locate it positivly SIMPLES really

hi ken,
can you not tap out the existing shaft in rudder, held in a vice then replace with a longer shaft of same diameter, i dont think it would have been cast with shaft fitted, would have  been  fitted after could be wrong though , i did this on a cast metal rudder worked for me.

Personally I don't like these big heavy cast metal rudders and their soft white metal supports. I use them as a pattern for stronger and lighter brass/wood replacements which can be designed to fit the space available. Manufacturers use white metal because it is cheap and convenient not because it is the best material for the job.

Hi Stavros,  Brilliant thinking about the plug pin. I never thought about turning it around.    %)

Hi David,  Thank you for the information about tapping it through. I might look into this today.

Thank you Colin. This was my alternative. I might have a go at making another one.

Cheers guys

Build another one, was the way to go.

I tapped out the old rudder tube and drilled it for a larger version.  A new rudder was constructed and fitted to a larger shaft with matching tube.  This was epoxied in and works OK.

Battery fitted and everything seemed to run Ok, so the decks were laid in  (but not secured down yet).

The weight was measured and it came out at 8 lbs, so well under the recommended 12 lbs.
