PostSubject: My Eileen   Tue Oct 28, 2014 11:30 pm

I sought of found with this modelling lark that you can run out of things to do, so, the reason I started in the first place was because I had a plan for MFV Eileen, had it for many, many years, started it twice and for reasons unknown didn't get very far. I was advised by others to buy a kit, which would be an easier build, hence the Fast Patrol Launch build.

Here is a quick catch up to where I am now.

I have a Burgess Band Saw and used it to cut out my basic shapes.





The keel/centre board and sheer boards are cut out.


And cleaned up


Fitting the stern tube and keel doublers.


Trial fit of a few bits.


I just love elastic bands, free from my postman 2thumbsup


Made a little mistake but I will repair and it won't be seen anyway.


My friend made me some profile gauges for the sides on his Ekold shrinker/stretcher.




I must have lost a few photy's somewhere Sad

Hi all, a little help required, I don't know what motor or servo for the rudder to use, some advice from you knowledgeable folk  for a novice on which type and size and where do others get these bits from please.

For a motor I would imagine a 545 would be ideal - it looks as though it will be a substantial model, but you are not looking for great speed. As for a servo, I find the miniature ones have sufficient torque for non-racing models up to 30 or so inches, but a standard servo would do fine. As for supplier, then either Cornwall Model Boats or Component Shop can supply both the above, and are very reliable in my experience.

The International Model Boat Show at Leamington Spa is coming up soon. If you are able to visit that you will find all you need there (and more Shocked )

What does 545 stand for, probably obvious but not to me the novice.

I'm not sure how I tell a standard from a Miniature servo either

forgive my ignorance, all the bitts for the "Fast Patrol Launch" came with it, so have not many clues

Paul,

A 545 motor is a 540 series motor with 5 poles. These are more efficient than straight 540s which only have 3 poles. Athough not marked as 545, this is a 5 pole motor http://www.componentshop.co.uk/540-standard-dc-motor.html

This ia a micro servo http://www.componentshop.co.uk/9g-micro-servo-3v-6-0v.html whilst this is a standard one http://www.componentshop.co.uk/25g-standard-servo.html

The difference is the physical size, as well as the power and operating speed.

Hope this clarifies things a bit.

You can get a bracket designed for the motor - check the web site, there is an option to buy the motor with a mount I believe.

Ok, assuming I go with this 540 series motor with 5 poles, what battery power do I/can I use ?

And what speed controller would I need ?

Paul,

A 10 or 15 amp ESC would be fine. That is a very low current motor. As for battery, 6 to 12 volts depending on your preference for NiMh or SLA - I wouldn't recommend LiPo for this application.

I had a little problem with the sheer boards, they were a bit kinked or wigglier that I liked, pondered quite hard on this and came up with the idea of putting a piece of hardwood at right angles and to the outside as not to interfere with the access openings I require for electrics etc.

Some photy's, I found a good use for the small cable ties that I have a pile of Very Happy

Hi David,
    I was given an old wardrobe which was edged with some hardwood, some teak like in colour (thought I would save this for decking) and some lighter coloured stuff, not sure what though. I have already cut the lighter coloured bits into some planks of 2mm thickness but still have more if I need to correct my mistakes. 

I have just uploaded some photy's of the planking, will put it in a post in a bit 2thumbsup

Photy's uploaded Thumbup

The first shot shows planks cut on the band saw, if you look at the left you will see a plank I twisted as a test and it seems to be very pliable, so I think good possibilities.





Bits of the old wardrobe which were my source for these planks.




Now I remember, I also cut up the teaky stuff for decking too.

I asked the relief postlady for a few as they would be handy and they just kept coming, now I have a carrier bag full, I had to ask them to stop leaving then as I think I must have as many as the Post Office do.

I found I had a little discrepancy in the deck level, about an eighth of an inch from one side to the other which I thought a little to much. So I made a board up for the planking job which has pulled it back within limits, not sure how others build boats like Eileen, I must admit I am making all this up as I go along, please comment if you use a different method.

Angle irons screwed to the bottom of a piece of ply.


chocked under and clamped on top.

A little more done here, I have put in the motor mounting shelf, U?J on the prop in reediness.
 

Also the start of the battery shelf.


Not a great deal I can do now until I see an engineering pal of mine who is going to make up a two part rudder assembly for me. The rudder shaft is to have a slot machined to take the rudder and will be secured with a couple of grub screws, much like a throttle assembly of a carburettor.

Coming along very nicely indeed Paul.

My wife flower gave me a present yesterday just to cheer me up.
A large bag of elastic bands.
My Son came round just to take the lift! with a load of cable ties.
All different colours.

A little more progress today, fitted the last and smallest bulk head but not glued yet as I need to cut holes in both the centre board and the this bulk head for the rudder post and it's control connections to the servo.



Also I was to strengthen the Skeg I believe it's called, the sticky out bit for the lower end of the rudder post, but have decided to cut away the wooden Skeg and use two brass plates (first photy is them rough cut) and solder a solid piece of bar between them, this will make things easier especially fitting the rudder itself.




Still needs shaping.


Also started making holders for the receiver and the ESC.

Getting the rudder position sorted now, I'll see my friend tomorrow who is to slot the brass rod for me.

I have cut removed half the slot for the tube, then placed a bit of ply for strengthening over it, when it's set I will do the other side.


Also roughed out holes for the rudder control rod.

Cut the slot for the rudder tube and plated it over with another piece of ply, I have left the brass tube out until I get the rudder and brass skeg made up so as to make sure they are fitted together and in a true line.







I ran out of clamps so had to be inventive Very Happy

I'm now getting prepared to fit the rudder which I can pick up Friday afternoon 2thumbsup

I am replacing the skeg with a brass bar with brass plates soldered to it, made this today and cleaned it up ready.

The reason for this move was that I caught the skeg and almost snapped it off, you can see the repair in the first photy.


My efforts in brass and soldering.


Lining it up ready for surgery.


I had to bite the bullet and cut it off.


Then rough out where it was to fit.


One of the many trial fits.


Nice and snug fit. Thumbup


Now to clear up the mess. Rolling Eyes


I will drill and screw in place once the rudder is fitted and probably glue or use epoxy resin stuff, not sure quite yet.

I would use resin and then screw in, stops any water that might find its way into gaps making a good seal.

I always try to leave it so that I can remove the rudder if necessary. Sometimes that's the only way to remove the propshaft.

Thanks for your thoughts chaps, Epoxy Resin was my choice but as Barrie says I may need at some point to service the rudder or prop. so I will have to think a bit harder or I might cause a problem.

This is the good thing about putting a build blog up, it throws up other folks thoughts and ideas for all to read too  Thumbup

I picked up my rudder shaft from my friend Barry yesterday, excellent job he has done, bought a little gas welding kit off of him too, with a small jet it will be ideal for soldering 2thumbsup





Just have to solder them together then the fit can begin. Barry did both ends of the rod for me, I now have a spare Thumbup

That's an interesting way of making a rudder. I usually just solder the blade to the shaft with soft solder. Shocked  I haven't had one come adrift yet. I have tried silver solder but my torch isn't strong enough for something as big as a rudder.

I had lots of thoughts on this Barrie and this was the decision, a flat surface gives an easier place to solder it, soft solder is what I will use but probably will go silver solder in the future. The little welding set will make it easy for silver soldering and the advantage is that there are several solders with different melting points which I will be using in my copper art projects.

I'm not sure how much it would affect the steer of a boat by putting the rudder on one side of the shaft. Ideally the prop needs to be central to the propeller and I would imagine the longer the boat the more its effect would have, my next one is going to be 54inches long so I think I want to avoid any chance of problems. Perhaps I am being over the top in this, it's just the way I see it.

Been doing a bit on the rudder etc. today and made some progress.

First I made the shaft fit and the upper guide tube.


Soldered the two bits of the rudder together.




Then set the tube in epoxy resin.


When it had hardened a little I removed the shaft and put some more epoxy resin around the tube just to make sure, then cleaned some off before it set fully to make things easier.


With the rudder in the loose skeg I thought it a bit low and might bind.


I needed a spacer and couldn't find a suitable non ferrous washer, so I made one from a tube nut (gas pipe fitting).


Newly made washer/spacer in place.




Soon be ready to have a go at the planking Thumbup never tackled this job before, so I'll take it slowly and see how it goes. Any tips anyone has would be useful. Very Happy

A little more progress today, I made a lever arm for the rudder. I was going to use a wheel collet but decided against it, when I drilled it out to the size required I didn't think enough thread was left for the grub screw to make proper purchase on the shaft, I had a feeling that the thread might strip.

I drilled two opposing holes in the end of the bit of brass left over from the skeg, 3/8square I think, and cut a small suitably sized strip of 2.5mm brass from a sheet I have and soldered them together. Then cleaned it up and cut a slit with a hacksaw through to the second hole turning it into a clamp.
 

Drilled a few holes.


Here it is with 4mm nut and bolt along with rudder, skeg and all.

Did a little more yesterday, I needed to get the rudder and servo link sorted so had to make a mount for the servo. I like these to be adjustable as it makes life easier when making the rod, as long as the rod is somewhere near the length I can then move the servo till it's spot on and central, saves removing that little screw that holds the servo arm for realignment.





Glued and clamped


Servo in place, it can slide in and out to get the correct position.

I learned from your trick of a sliding servo adjustment   Thumbup Thumbup  great Idea I've been modelling for 50yrs and never thought of that,
