by its coming along good that my mate - cracking job on the bulwarks

gives us an idea of the size of this model - seeing a Stanley Knife at the bottom of the hull  :-) what I would like to know is how much are you going to pay the crane driver to lift in and out of the water - few broken backs around the lakeside. :-)   :-) :-) :} :} :} :} :} :} :} {-) {-) {-) {-) {-)

Ah ha someone picked up on it .......Etch primer is used to make sure the paint sticks to the surface you are painting,it is ideal for brass,aliminium,white metal.
The only reason i used it was simple...I had run out of primer and I did'nt want to go 5 miles to get some!!!!!....The main reason for painting today was to see what work I have to do ........it is THINNER than primer and shows up all the rubbing down marks etc far better than primer,most of it will be rubbed off when I get it ready for paint.


I will probably use 2 pack primer filler on the whole hull sprayed with a professional spray gun...the main reason is simple really...the sheer size of this Tug as it is 6 feet long and will be cheaper in the long run especially as I want a baby smooth finish.


The red antifouling will be Halfords red Plastic primer and the Satin Black will probably be U Pol Satin black...this covers very easily and is a really strong black as well....The deck will probably end up a light green ...the superstructure and Bulwarks will be Ford Sahara Beige as that is the closest colour that I can find to the original

Thanks for that Dave, another question, i have a plastic hulled tug, sprayed with grey primer, it is flaking off in a number of places, is this lack of surface prep or should i use a flexible paint for plastic before the primer?

Yes it is either bad prep and it would really help adhesion if you used a plastic primer on it first

Lathes are great, definitly worth saving up for as you can make loads of useful bits in them. I love the information on the navigation lights and also how the hook developed into a model engineering project  :-))

Brilliant progress Dave, I can't wait to see it in May.

that looks interesting, Stavros. is that resin, and how long does it take to cure.


I look forward to seeing your fittings. Are you going to cast the brass parts as well that you made earlier.

Dave,
 if your casting  always have a spare mould near you as you always mix a little to much (which is better then to little)
 means at the price you pay for the stuff  nothings wasted by the way may i ask where you got it and how much you paid and I may be wrong but I have been told this stuff only has a self life of six months so I only buy 500m or 1kg bottles hope am wrong on this, I know the clear resin I have has thickend up over the last year while we have moved.
 
                Regards Howard.

The resin has cost me 30 including postage and packing,that is for a 2kg pack which is the smallest they do,and yes unfortuantly there is a six month shelf life...so I plan to use the whole lot up and then sell what I have left over to recoop the price of the resin and then anything I do after that all the proceeds will go to the RNLI.....anyone need some 1/12th vents and funnels then please contact me !!!


I have made 4 batches up tonight but as Photobucket is down I cant put the pics up....hence the reason there are no pics on the thread

Dave,
 As I have said before I got from Polycraft in Northern Ireland  good prices more so for water clear and in smaller amounts down to 250m if I remember  but postage is 7.99  no matter what but always packed and posted quickly.


                            Regards Howard.

Well here we are the pics of the casting.
To be  honest I was very lucky in that the aerosol tops were a perfect amount to fill all the moulds up in one mix....begginers luck without a doubt





Waiting for the resin to cure





Wey hey it has worked








I made up 4 mixes last night





I will be casting another 4 mixes up today of the small Gnv vents,obviously all the vents are going to need cleaning up this is  a simple process of rubbing down with some 240 grit.

That looks good Dave.  I'm very interested in your results.  You'll have to let us know how sturdy and workable the final piece comes out.

Cheers

On wards and upwards so they say so on we go.....the job in hand this weekend was to not only get the Propshaft in the hull but get the rudder installed and a Platform made for the rudder servo and electrics


First job was to get the rudder and support post epoxied in so a box was made and epoxy was poured into it




The Propshaft was taped up underneath to stop the P40 just dropping through the hole...Insulating tape was used for this





Yet again a little box was made up of scrap plywood to make sure a block of P40 formed around the shaft...also the shaft support had P40 also applied to it











The Shaft bottom support was made using some pine and through screwed to the rudder skeg,and also supported by means of some brass strip

Filler was then applied to the skeg and shaft








This was quickly followed by a good coat of etch primer


 





Rudder linkages were made up and fixed to the rudder post





A solid servo mounting was needed as the Barn door rudder puts a lot of strain on the mounting point so some rather agricultural looking frame was constructed out of 20x20 pine this was screwed actually to one of the deck beams the feet of this will be set into P40 at a later date


 







This has had a piece of plywood fixed  to it to not only hold the servo but the Esc and receiver...but that might change ...a Hole has already been cut for a servo





Rough idea of where everything might go








Next job is the Horrible one in my mind...A motor mount has to be made BUT the major problem is two fold really ....only 5mm underneath it and not only that but it has not got any mounting points ...so thinking cap is now on

Looks like a cradle and strap arrangement will do the job as motor mount.

Hi Dave, is that the battery that you will be using in the TID? if so wont it cause problems with stability, being so high in the hull????
