J. R. More
J. R. MORE - LAST OF THE LARGEST STEAM TUGS BUILT ON THE CLYDE. The best looking tugs ever built!

This model is scratch build at 1:48 scale of the SAR&H Durban tug J. R. More, which was the last large steam tug built on the Clyde in 1962.
It took over 2 years to complete this model, which was my first scratch build from the modified plans of a sister tug called the F.C Sturrock, which was also stationed at Durban as the shift tug for that harbour. Other tugs of the class were also stationed at Port Elizabeth and Cape Town.

The J. R. More was the newer day tug in Durban, most often used to service the Union Castle ships and others in, out of Durban and remembered by so many visitors to South Africa of that time.

This model tug on the water has differential motor control, software linked with the rudder, can go about on the spot and a delight to sail as a model, capable of 6 or more hours on the water. Working Rotating Radar, lights and woop-woop sounder as per the original tug. I would also like to install the Telegraph bells, however these would drive fellow modellers to distraction, as they were a very distinctive sound and very regular, Implanted and well remembered by the crews and those in and around the harbour, even today. The engines on the other hand were almost quiet and by all accounts very reliable.

This model is ballasted mainly by two 7 Ah 12 Volt SLA Batteries for the main drive motors and a 2 Ah 12 Volt SLA (Aft ballast) for the Lights, Radar and Sound unit. All up weight is 14Kgs and capable of above scale speed from the two MFA 6:1 ratio Geared Motors driving two 4 bladed 70mm screws.

This model has onboard charge regulator circuit, built-in minature dual volt meter to allow quick on-board voltage inspection and single plug-in charge and regulator socket for charging all 3 Batteries together.

The actual full size J. R. More tug still survives and can be visited at the Durban Maritime Museum in Durban, South Africa. Local supporters are undergoing essential repairs, restoration and preservation with private and company financial support.

J R More is the only surviving large steam tug left of this class and as Important to the skills of the Scottish shipbuilders of the Clyde.

Chatham Lifeboat CG-36500
Owing it's origin to the RNLI lifeboats of the 19th century, the US Coast Guard 36'MLB saw service from 1900 to 1987. The USCG built over 300 boats of this class in various "mods" spanning it's life history. Constructed of wood and fitted with a bronze keel it was powered by a 4 cylinder engine later modified with a diesel motor. Early powered 36' boats carried oars and sails as auxillary power. My 36500 model was based on the famous Chatham Lifeboat Station in Massachusetts, USA. On Febuary 18, 1952 the CG 36500 rescued the 32 survivors of the tanker PENDLETON during a night time nor'easter storm. Without radio or radar the Coast Guardsmen found the stricken T-2 tanker in the blizzard, taking the crew off one at a time. With each pass of the lifeboat a tanker crewman climbed down a rope ladder and "fell" into the lifeboat. With all on board, the 36500 found it's way back to Chatham harbor much to the delight of the towns people and the Coast Guard! The most amazing fact regarding this rescue was that the 36 footers were only designed to carry 19 people, including the 3 man CG crew, without capsizing.
The model was scratchbuilt of balsa strips and aircraft plywood, using official USCG blueprints. Powered by a 6 volt motor and a 2 channel radio, the Chatham lifeboat is pleasure to run in my local pond.

    Thanks Mike, I must try balsa. Just now I'm using 3mm pine planks which take some clamping while the glue dries. Like you, I resin wash the finished hulls inside and out.Regards, Ian.

    Hello, Thankyou for your helpful advice, I have now decided to put in an electric motor in the boat so hopefully it will be up and running by the end of next week.

hydrolift(26cc hydroplane)
this hydroplane had to have major work done to strengthen both sponsons internaly as well as filling with expanding foam,this stops it from sinking in the event of a flip over and to put a little weight in the front to help keep the nose down.
fitted a tuned wrap to center pipe,water pump and also added extra fiberglass on the bottom because this was so thin it was flexing at speed and was hitting the bottom of the engine!!!!!. re-painted it too and put my own choice of graphics on.
I fitted the pulse water pump because I wouldn't be running flat out all the time and needed to cool the engine at lower rpm's,and the pulse water pump would do just that with twin inlets and outlets to keep the exhaust and engine head cool.

    hI alan,
    a pulse pump works off the pressure of the downward stroke of the piston, as the piston moves down pressure builds up in the crankcase bottom and with a small tygon fuel line fitted to the insulator block that the carb sits on you can tap into the 'pulse' of pressure that's created and its this that works a diaphragm inside the pump, it pumps water when your boat is not traveling fast enough to cool itself through the water intakes.

    That is clever, thought it might be something that I could use on my fast electrics.
    Thanks for the reply.

Fleeting Star
HI Fellow Modellers,
Another model from the RADMC fleet at the fleetshaven workshop and boat yard in Ponthir.This model was built from a Caldercraft Kit, This model came into my possession for the price of 20p, a raffle prize at Bryn Bach Model Clubs OPen Day 2010, when it was built is unknown. The item being made for display use and not finished off, no internal electronic fixtures. Did have a prop shaft and prop that had not been fitted correctly. 50% of all the fixtures had to be removed and refitted before they fell off, some didn't stay in place from the show back home. The model was finised off using a photo of the Milford star on the internet. The fish boxes and figures being obtained off DON one of the Society members who had a mould to make them in white metal, only required cleaning up and finishing off. A graupner 6 volt steam unit is fitted in the funnel and to make the boat a little more realistic on the water,a maplin steam sound system has been used to generate the sound of the engine. A simple mod allows the revs to be linked to the engine voltage. The drive motor is a 550 with the lowest revs I had in MJB's this was married up to a 2.5/1 gearbox I also had in stock. The main motor and steam unit are supplied from a 7.2 volt nicad racing pack. This model has had meny fishing trips on Cwmbran Boating Lake and at shows the Society visit. Hope you enjoy the pictures, Regards GreyWolf.

African Queen
HI fellow Modellers,
Another model from the RADMC fleet at the fleetshaven workshop and boat yard in Ponthir.This model was built using a Billings Kit, bought for me as a Christmas pressent in 2009. A graupner 6 volt steam unit is fitted in the funnel and to make the boat a little more realistic a maplin steam sound system has been used to generate the sound of the engine. A simple mod allows the revs to be linked to the engine voltage. The steam engine rotates using a stripped down minI servo, fitted under the motor housing on the deck, again linked to the main motor voltage. The two 9.6 volt AA batteries and control gear are mounted under the boats floor, forward locker, a minI servo for steerage is fitted under the rear seat and the receiver is located under the wood pile. Figures are self made from items obtained from the local pound shop. The modal can be seen sailing at Cwmbran Boating Lake or at shows the society visit. Hope you enjoy the pictures, Regards GreyWolf.

my boat is powered by a 26cc zenoah engine,I skinned the outside in real carbon fiber and the interior with carbon/kevlar.I use a spektrum DX3S 2.4ghz tx with a spektrum MR3000 marine rx.the boat is equipped with a killer bee remote kill switch that doesn't need any power source to work so it will still kill the engine instantly in the event of battery failure or broken wire or when I want to from the tx. the carbon fiber was hand laid and wetted out with a special resin,then around six weeks of hand sanding with different grades of wet and dry to get it super smooth,then polish.

RAF Crash Tender
HI Fellow Enthusiasts
Photo shows my RAF crash tender in the colours as it was when first built in 1956/57 from a kit. (Red tops like all fire engines, well I was only 9 at the time.) This photo was taken at lakeside in 1993 when I first joined the Cwmbran Modelling Society. The Second photo shows the boat on display at the Portis Head Open Day event in 2000 several modifications taking place to the overall look of the boat. in 2008/9 I decided for it's belated 50th. birthday to revamp the model and bring it closer to the real thing. Damage to the woodwork being repaired and a colour scheme close to that of the real boat being applied. Several new deck fittings being made along with new window surrounds made out of plastic replacing the cardboard ones fitted in 2000. New decals and correct flag also fitted. The model was entered in the 2010 society Chairmans Comp. winning joint first place with one of my other models. Photo 4 shows my model as she is to-day repaired once again ready to sail, after hitting some Ice over the christmas period 2010 resulting in a hole in the bow that almost caused her to sink.
The model over the 54 years it's been around has been fitted with single and twin electric drives and to day it has a single johnson 550 brushed electric drive via a 2.5/1 gear box run off two 7.2 volt racing packs in series. The torque generated being too great for standard plastic props resulting in me using 40mm three blade brass props. The motor controller is an electolize 15 amp unit and I also use one of their switch units to activate the water pump for the scratch built water cannons. The water pump being salvaged from a 1960's car washer system and still goes to-day.
Hope you enjoy the pic,s as much as Ive enjoyed this model over the last 50 years plus.
Regards
GreyWolf

    Does anyone remember the 'Triang' Vosper Air Sea rescue launch?
    spent many happy hours on Letchworth town pond with that!
  • GreyWolfLeading Seaman
    HI Larryshaw48 🙏 Sorry for the delay, been down with a bug from before Christmas. Several of the Triang Vosper Air Sea rescue Lanches came up for sale before christmas on E bay listed under Vintage Model Boats. All seemed to be for sale with their original box and in fair condition taking their age into consideration. Never had one or needed one myself as the boat shown above has been with me from 1956/57.

Crash Tender Rebuild
Purchased from ebay and as you can see the boat has many problems paint peeling middle roof missing engine seized rudder Broken, but on the plus side the wood is undamaged. The boat comes from the original owner who built from a kit in 1964 And kept in his loft for years, I will post more pictures as rebuild progresses.
