Your tip on drilling a hole and using a half-staple to secure screws is a fantastic tip. {I had not seen this idea before.}

Thank You for sharing this one.

Appears that the manufacturer put a 50-L-4bl-M4 propeller in the bag labelled 50-R-4bl-M4  :embarrassed:

Interestingly, recent comments on LH or RH propeller selection suggested that LH had certain advantages in manoverability  ...

What is the hand of the propeller in the real vessel?........do you intend to exchange it? or use the LH unit? ... Derek

Apparently the Europeans do it backwards and read the props in reverse to what we do here. They read the rotation from the front!


I just got two Raboesch 50mm LH props from Float a Boat in Melbourne, and they had changed the RH on the header card code to LH in ballpoint pen.


Viewed from the rear, they are LH rotation props.


Hope this makes sense.

 %).....appears that Raboesch have now adopted the universal UK/American convention for the designation of propeller rotation over the previous European confusion and mis-understanding {-)  of such......  ....

'As if you previously ordered a right sided propeller then you will get the propeller which was previously called a left sided propeller'
 
%%......

Just wondering if Raboesch could simplify this even further by stating RH propellors = Right and LH propellors = Rong

I am also wondering if the VAG could use a similar misunderstanding in the Court?...............Derek

So right is left and left is right, right. Going to be good fun ordering from different suppliers

 I'll just run with servo reversed. Just a thought is an electric motor construction  designed to run (for clarafiction ) clock wise and anti clock wise.

Derek

Scotia has six blades on prop with a little dump on the end of each blade. So somebody in the yard ground  them off and a new blade was the order of the day.

An email from Raboesch said the prop in the picture was a left hand prop.

Not much happening at his time enjoying the lovely Scottish weather

Cut an opening out of the deck to get into the servo and rudder arm if needed.  Cleaned and roughened up the the deck bearers inside hull and glued the aft deck in place with weights to keep it down in place

Also been messing about with fiber optics,  considering putting some lighting in the model. Just working out how many strands of F.O. I can get from one LED.

I think the mid deck will be a nightmare to suss out and fit

Hi Seaspray
I have been putting some thought to the fibre optic . I thought I might flatten of the dome on the LED so the cut ends fit better to the LED then use shrink sleeve to hold the fibres together then use shrink sleeve to join them together.
In a former job I looked after sauna sang these had star effect in the black ceiling ,these were fibre opiptic made by Sovorski(maby not the right spelling).There light source shon through a revolving disk with a pattern in it making the lights twinkle . The fibres were all bunched together ,with each fiber having shrink sleeve on it then these were shrunk sleeved on to a short piece of acrylic rod and the hole lot covered in shrink sleeve ,then the light shone at the revolving disk , in this case the lamp was a 12volt dichroic bulb

Hi,

Not sure if you just want light at the end of the optic cable - if not check out "Light Pipe" as it emits light along it's entire length - available if different diameters. Put a controllable RGB LED and you have mood lighting!

Just heat shrink led to cable - this video will give you a snapshot of the effect achievable - a little bit like the toys kids have at concerts/out door parties - except they die after some hours when chemical reaction has finished...

Looking at those fibres you should not encounter the problem I did. Yours are quite a large diameter, mine were about 1/64th not much larger than a hair. I enclosed them in shrink sleeve and applied light heat, all the fibres melted inside the shrink tube! I'm talking about the heat from a match here, the shrink tube hardly moved but it was enough to damage the fibres.

So a bit of advice for David, don't go too small on the fibre diameter!

I've seen two ways of attaching LED to F.O strands. One was file the end of the LED drill a small hole on tip , not too deep to touch the elemant
push strand in the super glue in hole. these were on the Tube

G6SWJ
I did see the light pipe on the Tube too cheers . I was only looking for a light at the end of the strand but if you bend it seems to light up the whole strand. This I would use to light up the hull portholes and cabin lights. I haven't really got into the planning this yet but as well as having a good few strands light up the whole boat Just wonder if the LED strand placed in a deck light would give a good light like a wheat bulb.

Brian60
I have had a lot of problems too with a small lighter flame melting the F.O. strand and I  think  using a soldering iron on a small setting would probably do the same. I think it is a shrink wrap on the LED and try and get as many strands down a smaller tube and insert that into the shrink on the LED then glue the lot together. I also noted some of the guys on the Tube used  this method with a hot glue gun. Wonder if its worth buying one an hope it does for other jobs   

I've been using 0.5mm and 2.5mm strands Bought these on the Bay wonder if there are good quality

Lovely bit of woodwork there Martin - the deck levels are appearing to gel nicely. :-))

I had a little nudge from Bluebird regards the deck layouts and took a few attempts

pic 1 marking out the workdeck planking
pic 2 planking fitted on  on workdeck
pic 3 Also made planking for the sidegate  work area
pic 4 workdeck fits the cabin area and the doors have been glued in place
pic 5 the famous teabag mixed with coffee to give a stained affect
pic 6 the 2 deck stained and put in place

Those are interesting deck shapes the designers threw into the product, they look good.

More shapes to come and the winches and cranes on her. All good fun especially from a builder's plan

The little control cabin for the crane above it

pic 1 From a piece of spare wood was marked out ready to shape
pic 2 Shaped using the sander nice and straight edges
pic 3 The wood split don't know why as it has been under my workdeck for years. glued and clamped
pic 4 Finished the repair by cutting a groove along the split and filling with P38 primed and looks good
pic 5 Offered to the sprayed up midships deck looks right
pic 6 Using insulation tape I cut out the windows

I suppose that after years of being left to its own devices, the strains of being machined just releases the stresses in the wood and it lets go. I beleive that Cast iron needs time to relax as well after you machine it.

First time I've had this wood spilt on me and the first time I've shaped it  with the sander so your right. Its originally from the inside of a delivered washing machine it steadies the concrete weight inside it during transport and its very old piece of wood. Guess I was just unlucky but it glued back together no problem
