PostSubject: Models by design Tid Tug build...the Big un   Tue Jan 24, 2017 11:04 am

I was first introduced to the Tid's by now dearly departed next door Neighbour who used to own a Tid Namly a Tid called Bonchurch which was used to take fishing party.s and general Tug towing Based in Bangor North Wales at Penrhyn Port Bangor.I remember it like yesterday having been given the job of cleaning the fresh water tanks and cement washing them ...now a nice job believe you me.The Bonchurch is still on the water albeit now as a House boat and was last seen in Cheshire. 


Right then the build


This is what was done 5 yrs ago and I will bring it up to date after a few disasters along the way.


This was the rudder mounting 1st time around...yes it worked

Sorry but this is a rather poor shot of how the deck is held on...The wood pieces you see are bonded to the hull using P40

The Deck was made in sections which sorry Daz I couldnt remember how I had done it till I found these pics,this from what I can see is made with 2mm ply in more than one section and then it was Bonded to the hull with a couple of layers of 1oz Mat and resin and then tissue applied over it .



[url=http://s385.photobucket.com/user/broomsrck/media/Tid TUG 009_zpstrwngn9x.jpg.html][/url]


Deck Marked out and ready to cut out using a angle grinder with a thin cutting dicsc


[url=http://s385.photobucket.com/user/broomsrck/media/Tid TUG 016_zpsvbvjf6ie.jpg.html][/url]


Cut out and ready to be hand sanded to the correct line


[url=http://s385.photobucket.com/user/broomsrck/media/Tid TUG 017_zpsbspgaqfy.jpg.html][/url]


From this shot you all can see that the superstructure is not level with the deck so has to be cut down to fit level


[url=http://s385.photobucket.com/user/broomsrck/media/Tid TUG 012_zpsyr6vnwag.jpg.html][/url]


This is how it was done ....a scrap piece of plywood and a pencil cut down and drilled and used as a scribe,now as the deck is smooth it will follow the deck line and put the exact scribe line along where is needed to be cut

Right then lets get up to speed on this build.


A New shaft was purchased off Steve's Model Boat bits a heavy duty one that is Guaranteed not to bend like the old one...This was simply caused by a golf buggy motor on 24v !!!!...The new one will never bend as it has been built using a 12mm stainless steel inner turned down to a 6mm end and the same for the prop.


Propshaft is being supported by a scrap piece of wood bonded to the hull with P40.This as you can all see is held down wth some brass bent over to help stabeise the shaft and prevent shaft oscilation





This pic shows the new shaft arrangement and also the rudder Shaft bearer,you will see that the upermost Support has already been Attatched to the hull this was done by simply drilling the wood that has been shaped and glueing in the bolts using 2 part epoxy and P40,the lower part still has to be made...the brass strap that is at present seen in the pic will be removed when the lower part is made But a new one will be put form top to bottom to sanwich the shaft to the rudder/Shaft strengtheners.


 


This is the lower rudder shaft bearing that has been Silver soldered to the brass lower keel of the Rudder.

Right then sorry if the pics are slightly out of sequence ...but it seems I did not take any more pics of the build so I am trying to play catch up


Pic of Deck to superstructure coaming.The was done simply by screwing through the deck to some 1x1inch pine and then simply glueing and screwing the Coaming to it....this still needs to be tidy'ed up.





Picture of the Water Tank....the bolt heads have ben made by using the heads of ordinarry dress maker pins





Dummy steam whislte fitted to oneside of the Funnel,as you can see the other is work in Progress





Rear Towing Bollard,this was made by drilling some Brass tube and simply insering another through it...This was soldered with a 100watt soldering iron and ordinary solder





4 mooring posts...yet again a simple affair cross drilled tube and Soldered





Mast detail





This pic shows how tight it is for access at the stern once the deck is fitted and with me having such large hands beleive you me is not much fun





So the rudder build starts in earnest,Right this is a shot of the top rudder shaft bearing,simply constructed by cutting down a M4 shafted propshaft,This has a total lenght of approx 40mm,If you decide to do this you will need to cut the shaft accuratly an straight...easy to acheieve with a tube cutter,the baering is so so easy to get out ...simply use a drift and tap out,and yes you guessed it tap it into the new shaft





The Rudder components,This consits of a shaft,Main rudder plate...made using an old Door finger plate,3 shaft to rudder hindges.The hindges were made using brass strip cut to length and simply using a vice and a hammer to shape them,These of course will be silver soldered and not ordinary solder as this would simply be not strong enough





The rudder trial fitted to the hull.....There is still work to be done to the hindges cleaning and trueing them up before they will be Silver soldered to the shaft

Well after yeasterday's Fiasco of getting thing totally wrong and throwing around 5 flippin bullwark templates cos Dave got it wrong and then to cap it all I got the steps totally wrong I just wondered what could possibly go wrong tonight....So I decided to start on the woodwork on the bridge...what could possibly go wrong !!!!!!


1st job was to Mark all around where the wood was to go and also the door to the Bridge





Right then as you all can see there is a radius around the bridge so we have 2 options available to us,either fill the radius out so you have a 90 degree corner....well that would be cheating and an easy way out..OR bend the wood round the corner.Anyone who has tried to bend wood cold knows what happens it splits,so what can we do...Well there is only one course of action left.Steam it or soak it in water...the wood I am using is 1/32 thick planks...To Be honest with you I am not a great beleiver in getting wood soaking wet.....But as I did work in a boat yard and had to bend teak planks around the deck edge by means of a steamer.
Now how can we steam wood...you either make a proper enclosed steamer or you simply get the old camping stove and a kettle out......You simply boil the kettle and leave it on the boil so it produces steam,Now for heavens sake BE CAREFUL when doing this as you can get SERIOUSLY HURT if you do not be careful......If you get hurt after this article I WILL NOT BE HELD RESPONSIBLE.
The plank needs to be steamed for  a couple of mins till it becomes soft now the trickk here is to work fast and carefully...clamping as you go and not to be too greedy...if it does'nt feel right STOP and resteam(MM DAVE why didnt you),do one side at a time ...wait 5 mins then simply do the other side,if when you remove the clamps the first side straightens up simply resteam it clamp up and pull gently round the other side.


I will confess one little thing here I did make a right pigs ear of this and had to scrap 4 before I got it right...I can obviously use these bits to do the planking so all is not lost


Steaming in progress





1st side bent





2nd Side










This will now be left to dry overnight and it will retain its shape and will be glued to the superstructure with Zap superglue.
And before anyone picks up that the wood is not straight on the bridge front...I know and Ive been out to the shed to correct this so it will be ready for tomorrow !!!!!


Whilst this was drying I started on the rear of the Bridge so a door frame was made using 1/8 mahogany strips,ready to be planked,All around the bridge will have to be individually planked right up to the roof.


Now here lies a bit of a problem as the roof of the bridge is square and it should have a radius on it...This I will show you how to do at the next installment

Right then Proof of the pudding so to speak....after 24 hours the wood has dried out and has retained it's shape after steaming





Now glued to the bridge

PostSubject: Re: Models by design Tid Tug build...the Big un   Tue Jan 24, 2017 11:16 am

Right then lets get the roof of the bridge planked,right then we really need to sort out the camber of the roof  so the center was Marked out and a piece of scrap wood was used around 8mm x8mm and a couple of 4x4's were used on the edge of the roof,this allowed a decent roof camber





A piece of ply was then glued to these so I could plank it over and a center line was marked so I could start form the middle and work outwards





Around 40 were needed for the roof alone 





I was initially going to use Pva Waterproof wood glue but changed my mind as I couldnt wait to get it done so Opted for Gorrilla Glue the Gell one...must admit this is spot on so so easy to use and I didnt even stick my fingers together and is waterproof as well





This is the roof around 3/4 done 





Roof Done..But you will see that the planks are higldy pigldy so to speak and need to be rubbed down to the wodth and length of the plywood roof,How do we do that may you well ask...well very simply really...I made a rubbing down block by simply glueing a peice of 80 grit sandpaper with spray glue to a block of wood..I also made one of 180 grit and 400





Here you will see that i have started the vertical planks that go around the bridge are 







This was done in a similar way to the roof But a dremel was used to get a rough shape and then a simply filed to finish





As there are windows around the bridge a window frame is needed I will show you how to do this on the next instalment

Right then Window frames....the Stav way...whether this is the correct way lord only knows but is has worked  for me and thats all that counts .


Firstly i glued the inner part of the window frame to cover up the edge of the fiberglass....yes it is far to oversize but it is easily sanded with a block.





This is showing the frame sanded down





Then a simple frame of much narrower planks were glued to the outside to cover everything up...simple but in my mind effective





Now me being the impatient fellow decided I would try out the woodstain that I purchased in B&Q just so I could see what it was like

Wey hey managed to get a full day in the shed today so I actually managed to finish the cladding of hte bridge and make all the window frames.....phew thank goodness that's over and done with.
It was then given 3 coats of light oak stain...more like dark oak !!! But to be honest with you I wanted it dark as all the Tid's were this way








I now had to construct the Port and Starboard Navigation light Boards  which I will now endevour to build some lamps for it...unless of course I can get hold of some 1/12th scale old fashioned ones





This is being held up to see what it looked like as it will need painting before it gets glued on to the bridge

Right a bit of an update on this build.........A couple of the deck vents have been built to be used as plugs so they can be cast in resin....main reason for this is there are 14 of the little blighters on the Tid all down the sides of the hull.They will be used to make rubber moulds ready for the resin casting,Also a technical drawing was made in 1/12th scale of the rather large  cowl vents .


Now a rather large confession here...not knowing a thing about making rudder moulds let alone my skills are simply not good enough to make some cowl vents of that size I simply asked a god friend of mine HOW do it do this and what do I need to get to make the rubber moulds etc etc....his ONLY answer to me was ...send the vents and a drawing up to me and ill make you the moulds and you can make the resin bits...............That Friend was Neil Howard Pritchard no less,to say I was gosmacked was an understatement.......




NEIL can I publically THANK YOU for this 




Dave

Right then onwards and upwards as they say...Today's tasks were pretty time consuming to say the least and made me really think what I was up to.


First job was to do some work on the lathe to true it up and thanks to a gent form Bethesda who just was just going for a walk past my house made that job a doddle....Thanks Billy.


With the lathe running true it was time for Dave to do some turning....What do I know about this subject...well Ill be honest with you all....Naff all.....I honestly ain't got a clue what I am doing so it was rather trial and error,trust me on this.
I managed to turn 4 small pulleys for the Roller fairleads and believe you me they ain't to bad...well I would say that !!!


These were drilled and then the frame was made up with some brass strip....I only manged one as I ran out ...don't ask


 


One of the completed rollers





Next on the list of many jobs was the towing hook...........I decided to scrap the Mobile Marines one that I has(SORRY BRIAN) and canabalise it as I wanted a hook that not only went from side to side but up and down as well.
1st little problem with this was the gimbal on the one I had was to big by 5mm so into the lathe it went and was turned down...the actual hook was filed out to gain a bigger throat,new side cheecks were made and the actual hook bracket was made and silver soldered and 2 bolts were also soldered so it could be attatched to the superstrucre ...there is of course a spreader plate inside the superstructre.

















There was one little job that I have been putting off as I had not got a clue how to do it till today....Ah ha I said Lathe,this was the cap on the Galley stove,it needed a Chinaman's hat on it so this was duly turned down and made.














The observant amongst us will notice that at the moment that there are no holes to allow the smoke to get out of the chinamans hat  this will be rectified tomorrow.

Right Neil has sent me these pics of the process to make the rubber moulds that will enable me to cast these Vents out of resin.

















The cowl vent were made out of Obeche wood and hand carved...The 2 plastic card Gnv vents were made by myself and these are the moulds to make the rubber moulds ready for casting

This is now the state of play regarding the moulds for the vents.
The 1st half of the mould has been poured with the rubber compound to actually make the moulds and all the plastascene  has been removed........as soon as Neil has tydied up the moulds he is sending them doen to me so I cna start to make the vents .....obviously I am going to need to make 2 of each of the cowl vents and a total of 14 of the GNV ones.....




Prior to the removal of the plasctecene


 


Large cowl vent,you will see it is not full lenght...the bottom of the vent has a recess which a 24mm copper pipe wiill fit making ti full length...the same will happen to the small cowl vents but this will be qa 12mmm copper pipe

Well I decided to do the filler work on the bulwarks of the hull today so I can start to put in all the extra strengtheners that are needed.


As it is a grp hull these need to be smoothed out so you don't see the weave of the glass fibre,this is a tediuos and horrible job,first I rubbed them down with 80 grit paper dry to key the grp,then some filler was applied sparingly then rubbed down again with 80 grit then finishing off wiht 180.




This is what I had to fill








The screws were removed along the inside of the superstructure coamings





This is the filler I use,along with easy light and top stop....very easy to sand





Correct amount of Hardener is really important as this stuff goes off like stink even in a cold workshop





Mixed filler 





filler applied











I then primed with a Halfords etch primer













These are the moulds for the vents ready to be cast when I get the resin

see ya got the good stuff matey.

with that you'll be able to take a sharp craft knife and pare out the inside  of the large cowl vent to a thinner wall to make it look much more realistic with a thinner "wall", as the polyurethane can be carved for a good length of time before it hardens to a harder state.

That stuff looks like fun, I want to have a go, is this the best stuff to start with? I looked before and found it daunting with the amount of products available.
Where did you get it from please ?

hi troutrunner,

It all depends on how fast you can work.....this is quick set polyurethane resin, which as I said earlier won't snap shatter or break and is carvable if you want to trim it down, as opposed to polyester resin which shatters and snaps and has no residual strength.it also has very low shrinkage problems.

Also if you have a lot of castings to do of larger items, you can get through a lot in a day, lol

On the down side it starts going off within a couple of minutes from mixing and within 3 minutes it is unusable because it is almost like rubber before it finally sets and starts to cure. you also have to be very accurate with the 50/50 mix or it won't set.i use a set of digital scales in grams to get my mix right, and the big problem is, after first opening the two tins you have about 3 months shelf life on it before any future mix comes out like honeycomb crunchie bars......just a mass of bubbles..plus if you don't have a lot to cast........expensive........those two tins that I recommended to stav cost with postage around 23 quid I reckon, maybe more.


CFS is the company.....google it and look at the range of products.  http://www.cfsnet.co.uk/

neil.

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.

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 actual 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

great stuff, keep it up.

There is method in my Madness Neil...I am rather hoping that I can fasten the superstructure to the Rear wood for towing obviously glueing another peice of 20x20 to the one that has been screwed on...the one nearest the stern.


Oh and Ive had an EUREKA moment....I am going to wrap the motor in cling film and coat it in vaseline....Make a tough for it to sit in .... and pour in the casting reisn and hey presto a motor mounting.....sound so so easy...I do HOPE IT IS

Well an engine mounting had to be made...I already knew I needed a gap of 5mm between the bottom of the motor to the hull so this was drawn on the plywood as the bott line of the side cheeks of the mount.
I used a plastic shape finder(cant remember it's name) to get a rough idea of What I wanted and then divided the dia of the Motor in half so I could use a compass to scribe what I had to cut out 








Now I built up a casting box so I could pour the resin into 







Testing it was the correct height





Obviously if I simply just poured resin into this all I would get is a oblong box...so the Motor was wrapped up in insulating tape and Vaseline was rubbed all over it and also the casting box,This was done to stop everything sticking together and also to get the Mounting out of the casting box.





The white stuff is simply Sticks like the proverbial...this was used to stop any of the resin escaping out between the motor and the casting box

Mounting as it came out of the casting box








I them sanded down the new mounting to clean it all up 







I was very lucky and found a Half round bracket in th egarage that fitted the bill so I then simply drilled the new mount and inserted an allen headed bolt in from underneath and simply put a nut with a spring washer on it...YES I will cange it for a nyloc nut later





The whole affair was simply screwed to the hull ...mission completed 














Oh my work was inspected this afternoon by Bethan

So I started with the electrical instalation so a new servo piece of plywood was made and extended to cover the motor so I could mount all of the gear out of harms way


The first to be placed on the mounitng board was the Esc....all the electronics being used are ACTion





I decided not to use the ACTion distribution board and use a car blade type fuse box to feed everything but to use an ACTion bec obviousy to feed the esc and reciever......The components placed on the board are a P98 High power esc,an ACion 93 Multy controller a ACTion Amplifier and a P100 Noisy thing





An illuminated rocker switch was also installed ...this will control a 40 amp car relay which when switched on will allow power to be fed to the fuse box etc





Pic of where the relay....all the power cables have been encased in some proper electrical sheathing and had the ends heat shrunk...............all the auxillary wireing will be encased in this as well,should keep Mr Milbourn Happy





Having run out of cable I decided to do i job Ive been putting off for months ....the bullwarks...unfortunately every single one is different so I cant mass produce then ARGHHHHH...so I needed to assertain the correct angle of the deck to the side....nothing I have would do this so I had to make on...a very simple tool....2 pieces of brass bar with a nut and bolt through it ............nothing beats simplicity in my mind.





Proof of the pudding 2 bullwark supports made....simply using some lite ply and some thin planks glued on edge to the support





Between some of the support these vents will be simply glued to the sides of the hull

Let the fun begin oh what a right chore the Bullwark supports have turned out to be,each one has to be individualy made,oh the joys of boat building,mind you if it was so simple it wouldnt be fun would it.
I have managed to get down half of one side of the hull in an afternoon so I hope by tomorrow to get the other side done,one of the most sattisfing well it was to me was being able to mount by vents to the side of the boat nad aslo the coaling scuttles....mind you they do say little things please little minds HA HA.


A section of the sides with the supports and Gnv vents attatched to the hull sides





Coaling scuttles fitted







I also fitted some of the posts as well





Primer was applied to make them look the part
