The saga of the leaking Clive Puffer Several friends had mention to me that the prop needed to be above the water line so out came stuffing box mounted motor higher so prop shaft above water line & replace shaft & prop shaft . While doing all this It donned on me like a light going off that the rubber shaft was lower than the water line & I think water was entering up rudder shaft . Photo shows area where water was when it was in water & the tube for the rudder shaft was below that so added more stern depth .Made up another rudder shaft that is higher & tube is also now higher.

As promised A few photos & some members models in Spencer's pool Burlington. Some of the boats shown are from other model clubs mostly Toronto modelers so I can't mention names of members boats because I don't know their names. Still lots of time for sailing & the puffer still leaks so I'll put stuffing box on a steeper up angle above water line. I just love fixing a problem with my model boats.

well finally got there. she sits a little low in the water, but evenly along the water line. this was with the battery central to the hull. when powered up the centre screw alone moved her quite serenely and was very manoeuvrable. when power was added to the outer screws I would say she didn't plane well as she wasn't going fast enough. even with all props on full power, I think also she is to heavy and the battery too far forward.
So to remedy this I moved the battery back a compartment, positioning it over the 3 motors , it was a tight squeeze, but fitted just.
This sat the stern down a little and the bow up and gave the impression of planeing, she still not fast enough though. the scale speed still doesn't look right.
I'm going to have to have a rethink on this one. having said all this though she looked well in the water if i say so my self.

Took time out from my new build to test float the barge I am building for my push boat to give it a long awaited float test for leaks and to mark the waterline. First decent day this winter!

Model undergoing sea trials after painting, note rudders are too aggressive.

Brought this vintage Aero Kits RAF Crash Tender for £50 from Newcastle area, it is the 34in version.
To my surprise at home I found that it had a Bullet 30 motor installed these motors were the top drawer motor of early fast electrics in the early 1980's and its the only one I've ever seen, it can run on 24v and pull around 15A giving 300w not bad for a brushed motor.
due to the power of this motor I have modified the hull under the water line with turn fins and trim tabs to reduce torque roll and improve turning stability, the underside is incorrect already as it only has one propshaft, where the original had two and I believe that both props turned in the same direction.

The Pictures here show some of the work in progress I have remounted the motor and added a speed controller rated at 24v
I have remade the stern compartment and rudder gear under it.
I have blocked windows and foamed the front half of the boat.
made missing parts and repaired delaminating ply.

Note old ply is not as good as modern, the glue is not as water resistant.

Have painted the hull and have just ordered the decals from Cornwall model Boats :-https://www.cornwallmodelboats.co.uk/cgi-bin/sh000001.pl?WD=hose%20fire&PN=becc_fire_tender%2ehtml#aB_2dFTS1_2e32

The 34in is 1/16 scale

Fitting can be brought but many are cast white metal and can add weight to the boat, I have made two water cannons and plan to buy plastic fittings from this site.

This has turned out to be a task that is difficult to assess how much effort and money to spend on a hull that has been built by someone else (say no more).
Have just finished the steps for the stern compartment.
Painted and now for the test run.
the Bullet 30 motor ran well between 14 and 18v,

47" working Narrowboat. All wood construction but have fibreglassed below the waterline. Plenty of detail in the living quaters

HMS Nelson, scratchbuilt to 1/8" scale. Powered by two motors driving twin contrarotating shafts with three blade props. She sails on Lake Lisgar, Tillsonburg, Ontario.
I decided on Nelson as she took part in Operation Pedestal, from which I made a 1/216" waterline model of SS Ohio, the ship that saved Malta.
She took a little over 600 hours from solid chunk of basswood to launch. Probably info collection took as long!

It is an rc model that consent the customizing of the cockpit cabin but it comes in cheap colours (red, yellow and gray) so I decide to go to a real nautic shipyard to paint with nautical lacquer in a real creamish White! added some decal for water line and lights and scratch build anchor

First time in the water and under power. to get the correct trim (ect) I built a test tank from ply and lined it with polythene. To stat with There were two 12V lead acid batteries and the weight of the two motors, she just simply sat there, even the props were above water. After approx 30lbs more weight the correct water line was reached, the white line on the hull follows the sheer line of the main deck and isn't the true water line. So with the two batteries hooked up in parallel, the 12V Proboat Speed controller and the two Duma 12V motors as can be seen quite a good performance.

I built this Range Safty Launch two years ago and I am now changing the hull paintwork to also include a water line. I never got around to doing this for some reason.

Range Saftey Launch

I purchased the plans for this model after my late father passed away, he too was building this model but failed to finish it before he died. My father was an Ex RAF Patrol boat pilot, hence the design was appropriate. The plans (Two sheets) are really well presented and easy to use. Each of the sheets provide ample detail to construct the basic model and if you are an experienced builder then these should suffice. However, a little research may be required to put the final touches together for the completed model (If you are a perfectionist like me). These plans are suitable for a novice as a first time project. This being my first attempt at a scale model. The boat once completed sails really well. I fitted mine out with electric motors, speed controller etc and when on the water a few heads turned! Fantastic plans GO FOR IT! Roy McCluskey

1/12th scale Guard lifeboat still not finished still havent painted the cockpit thats why the blue window but just couldnt wait to see it on the water. Powered by twin Pittman motors it has six low profile 12v batteries mounted below the waterline to aid in its self righting.
