MMB's ASD Harbour Tug (The Official Build)
« on: May 14, 2010, 09:45:32 PM »

Hi all,
           Now that my Smit Japan is finished it's time to start a new build, and why not start with a new model that has just come onto the market.
            MMB's ASD Harbour Tug.
               www.marksmodelbits.com

I was lucky mine was delivered by hand by the man himself and Ang
(Please do NOT expect the same service, the price of fuel would bankrupt him)

What do you get:-
Fibreglass hull,superstructure and wheelhouse.
all the deck castings made from resin
Motors, shafts, steerable korts........ it's easier just to look at the photo below

Right first thing first, make a stand, i made mine from 1/2" MDF and stained it so it's waterproof.

Looking at the hull you can see the usual mould marks these were easily sanded to remove them,then the whole hull was sanded with 240 wet and dry.

Hy Jenno
I,ve seen your Smit Japan, and some of your other builds and they are all outstanding, I dont think Mark could have found anyone better to show of his new production, if it comes out half as good as the Smit it,ll be a cracker. :-))

Hi all,
Thought  Id start the superstructure  a nice clean moulding is supplied, you only need to clean the bottom where it sits on the deck ,washed all the resin parts and sanded them down on a piece of sandpaper taped to a board. There are plenty of doors and hatches supplied in the kit so you can choose how many and were you want to fit them, after everything was dry I filled any gaps with P38.
Next came the hand rails, There a some nice brass stanchions in the kit, and a quick twist here and there it all fits nicely in place.

                      Jenno.

That's coming along nicely jenno, makes me want to get hold of mine, ordered at the South West Model Show at Shepton Mallet. My fault though, for saying to Mark that I'd pick it up at the Weymouth Show! At least I can take pleasure (and notes!) watching your build; superb work as usual.

Hand rails on the superstructure are nearly finished just need a little filing to clean them up, the remaining rails at the rear will be made and fitted when the wheel house is finished.

The winch comes with a diagram which is easy to follow all parts were washed, sanded and assembled quite easily, the rope will be fitted after painting.

O.K now some technical stuff, the Kort nozzles need to be trimmed down,                                                                 
2mm off the top of the kort and 5mm of the bottom of the shaft casting
see pencil lines on them in the photo.

Now with the two pieces glued and filled the holes were drilled in the hull and the tubes fixed in place Now these tube are special they have PTFE bearing, Ive never seen bearings on a rudder/kort before(Please correct me if Im wrong)  There are two large resin blocks supplied which I drilled out to 6.5 to fit over the tubes  when everything was lined up, square, parallel and looked right the blocks were lifted and fixed in place with body filler P38.when dry I fitted the tiller arms and connecting rods and walla   two working korts.

Time to fit the shafts, firstly I cut 2 discs at 48mm Diameter so that they fit tight in the korts and fitted them to the screw end and then drilled the holes in the hull, Because there is approximately 100mm of shaft sticking out I decided to fit P frames, made  from 7mm Dia brass tube soldered to a piece of brass plate which fits through the hull and a piece of thin wire and P38 to hold it place. I used a piece of stiff plastic in place of the rubber on the coupling to line up the motor to the shaft then when the filler under the motors had dried I then fitted the rubber to the couplings and drilled  through and fitted the wire to secure them.

O.k. back from a weeks break so Ive made a start on the deck
I firstly sanded the fiberglass to give a good key for the deck supports, I used superglue to bond 6mmx3mm strips of plastic to the hull ,once they had dried I then used revell contaca liquid glue to fix the second strips in place. I then made three  beams which fitted from side to side to support the centre of the deck. i also made a box to for the steering servo to fit into, once all this had dried I went all around with P38 to give extra strength.I also made the funny bit that fits to the bottom of the hull see photo below.

With all the frames in place I cut the deck out of 1.5mm plastic card any gaps will be filled when dry.

Now that I have the plans for the wheel house I transferred the measurements to the styrene sheet which was supplied, then cut them out.
I also cut out some templates to give me the correct angles for when I glued them together. When the glue had dried I then fixed the door side panels in place.

Hi Jenno
Nice work.
Can I just ask why you are doing a plastic card wheel house when your
first picture shows a moulded one?

Hi Derek, We were originally going to supply a GRP wheelhouse moulding but we were not 100% happy with it, looked fine from the outside but would require a huge amount of work to get the inner surfaces flat enough to glaze properly, so we decided to scrap that idea and go with plastic card instead, the wheel house is, after all, a major feature of the tug  (the card is included in the kit)

These are the jigs that I made from the plans so that the correct angle can be achieved for the top window panels.

Now with the wheelhouse nearly finished I made a start on the mast, I turned a dowel to the required diameter and gave it a coat of sanding sealer, then drilled 1mm holes for the wire stays etc. When everything was dry I then fitted all the lights on.

Ive also made a start on the inner bulwarks, using scrap 6x3 strip plastic for the bottom supports and 1mm plastic card for the sides.
