Which way do your props turn?

It may be to do with the prop/motor combination, particularly prop sizes. But rather than try and experiment expensively I reckon a mixer is the best way to go in this case as then you know you will get the maximum turning power which is important in a big model like this. Lot's of info on ACTion's mixer here: http://www.action-electronics.co.uk/pdfs/P40C.pdf

Mixer seems the best way, must agree.

Hi Imara builders everywhere
As my Imara build nears completion I'm at the stage where I need to taper the mast and as far as I can see there's no easy way without the aid of some sort of lathe which I don't possess.
So if anyone out there has any ideas I'd love to hear them!

Hi Brian,

You can clamp an electric drill in a vice or even a workmate, put your mast in the chuck and work it like a mini lathe.

Have used this method for all sorts of things.

Cheers

Dale.

Hi Brian I did the same as Dale.

Make sure your mast is over length as the chuck will embed itself in the end.

The drill method is the one I used, but I do have some advice.

The speed doesn't have to be exceptional and sandpaper works a treat.  HOWEVER..... do not wrap it around the spinning wood completely as it will SNATCH and may entagle your fingers.

Ensure the trailing edge of the sandpaper is LESS then 180 degrees around the wood. I speak from experiance, as the leading edge caught the tail of the sandpaper and quickly wrapped and reeled the  paper (with my hand) inwards and snapped the wood before damaging me too much.  (difficult to play the piano for a few days!!)

Whilst working the wood to a taper, stop frequently and try the mast hoops for diameter in their respective places. It's easy to over sand and ruin the piece.

Best of luck

Ken

Put the sandpaper round a flat file, it gives you far more control and only works in tiny arc.

I also use this method, Bob, but found I needed a counter pressure underneath to prevent 'wobble' of the spindle.

Which brings me to ask what to use, as the 'ol fingers' get a little hot with the friction. ( the perfect solution would be a tailstock of some sort)

If you have a pillar drill grip the mast with sandpaper then you don't have to grip the mast so hard.
If you can push the mast up high into the chuck.
If you cant just use 2 files covered with sandpaper, one on top, the other on the bottom, but sand LIGHTLY.

Thanks everyone, all so helpful as usual, I've tapered the Imara mast with a combination of drill, sandpaper and bucketloads of patience!

Hello, instead of covering a file with sandpaper I use sandpaper covered nail files (finger nails) for the masts. They work great and there is no danger that the sandpaper can catch and cause damage.

sorry nemesis, but you've got the wrong Perseverance then, because Imara was definately twin screw and all RN did was change the name for her service as an RN tug. {:-{

Hi 'all' just discovered this site wish it was around four years ago when I bought the IMARA tug!!
My build has been on and off all this time and I'm at the stage where, hopefully it'll go in the water this year I
Overall I am fairly impressed with the model but the beast has certainly tested my modelling skills.  First the hull then the superstructure etc etc .  I like most of us I guess have in many instances deviated from the instructions and used a bit of engineering nouse to achieve success in an alternative manner.
With restect to mast for the smaller mast I sourced a variety of wooden handled paintbrushes removed the bristles.  With the main mast I used a power drill to hold the dowl and 120 grade sand paper to achiev a mast that looks the 'bis'
The ships boats were a nightmare but I managed to salvage a pair of boats from the mouldings.
Not impressed with the decking so I managed to find some material in a model shop here in france that I have used as planking and managed to plank the boat using a black cotton as 'caulking'  this has taken me hours and I usually sit in front of the tele with a board on my lap styling and sticking down planks.  Oh what we do for authentacity!!
Next the white metal bits some of these like the forward steam anchor winch has got me beat.  Just when I thought I had cracked it the rotten frame snapped grrr.  So if any one can tell me where I can get a replacement look alike winch I'd be grateful.
I haven't yet plonked the beast in the water I was waiting to complete the build before doing this.  Reading other posters comments this may not have been a good idea ie it might have been better if I had sourced motors etc fitted these to the hull and tested the operability but hey ho every one to his or her own.
So again if anyone knows where I can source a steam winch I'd be grateful or if nothing else its back to Caldrcraft to source another pack of bits to try again!!

Hi Polycell
Hope you're enjoying building your Imara as much as I am, but you're right it's very challenging ,and where do all the white metal bits go?!! Mine's nearly finished and I've a number of these to find a home for.
If it's not too late I would strongly recommend that you test her on the water during the build as it's quite a problem to rectify any mistakes especially once the deck's in place.
Thought you may like to see a couple of pics of my Imara, you'll notice that the lifeboats aren't on yet, I've put off the tricky jobs till last!
