I finally got the boat on the Water at Jubilee Pond - the home of Southport Model Boat club
We took some video, which I have uploaded to You-Tube, as I don't know the max file size I can put on this site

Hi Colin,
I have almost finished my refurbishment
My model is just under 36" long, and there's details about the electronics / motor etc on my build page if it will help Hoping to do my test run on a lake v soon, but it ran well in the paddling pool on the lawn recently!
Good luck - it looks just like my Aerokits model
I think I put the plans I have in my build page, but I have 2 documents - 2xPlans, and How to assemble
Regards,
Bill
Here's the link to my build page:

PeteJev,
Thanks for the suggestion re SLEC. I actually had them make me a set of windows and frames for the version of the boat that I have, but I think my drawings were "not the best", so am still trying to decide what to do - and consider if I need to leave the windows out to keep the motor cool
Regarding the FIRE and roundel decals, I will paint them if I decide to add them.
Since my last post I have done a successful bath float test, with no leaks, and need some small weights for ballast to the waterline!
Your boat is looking great, and I like the stand you have for it!
Cheers!

๐ Painting and Fitting-out
5 months ago by
๐ฌ๐ง Back in the Groove (

I used Johnstones Trade Wood Primer and Grey Undercoat for the base layers, sanding between each coat to try to get a smooth finish. The hull is painted "Victory Red" and "Black", and the waterline painted white with Craftmaster Signwriting Enamel
I made a frame to sit the boat on, using my laser level to project a level line on the boat and after an attempt to paint to this line, changed to sticking a masking tape layer along the line to get a decent line. It was really difficult to paint a line over the chines!
I used Craftmaster Signwriting enamel for the Upper structure - in Silver Grey, Charcoal and Raw Sienna - unconventional it maybe, but at this point I'm not planning to add any fittings to the boat, other than Port & Starboard lights, but am very tempted to paint FIRE and add the RAF Roundels - maybe after I've done running trials!
I've still to fit the rudder mechanism, but filled the prop shaft and rudder post with grease, and tested the RC, and it all works, so ๐ค for a water test in the bath soon!
Do I add polycarbonate windows - or do I need airflow through the boat?

๐ Restarting the Refurbishment
6 months ago by
๐ฌ๐ง Back in the Groove (

Petty Officer 1st Class)

After a very long pause ๐, I have resumed work on the Crash Rescue Tender.
I found and tested the new electronics I'd bought:
Controller: M-Troniks G2 Hydra 50
Motor: M-Tronics Brushless 1900KV 600can (came with Controller)
Antenna: Futaba R3106GF
Rudder Servo: Futaba S3004
Batteries: 2 x VP Racing Battery Ni-Mh 10x2600mAh 12V
Transmitter: Futaba T6L Sport
and found the new hardware:
Prop-Shaft: 9โ x 5mm dia. (8mm dia tube) with bearing
Rudder: Brass 5mm shaft
Having stripped the paint from the boat, and removed the old propellor and rudder tubes, I set about fitting the new propellor and rudder tubes.
I made a new motor support to ensure alignment with the propellor tube.
I had to enlarge the prop tube hole to 8.5mm to ensure the resin would flow all round the tube for the best seal
Having never used this type of resin, I went for Z-POXY 30min 2-pack, sealing up the outlet of the rudder tube with blu-tak (with space for waste that I would file off once set) and made a small frame from thick card to contain the resin in the hull I drilled a hole to ensure resin got all the way into the prop-tube hole. I poured the resin with the motor, prop-tube and shaft, and outer support all in place to get good alignment, and twisted the prop tube post-pour, to ensure the resin flowed all round for a good seal
I would use a shorter set-time resin in future!
Next, I set about fitting the missing gunwale rubbing and chine strakes. Over 50 years ago, Dad had obviously decided heโd gone far enough and hadn't fitted any.
I steamed the Obechi Gunwale strakes using a plastic tube and wallpaper steamer, then clamped them to a frame mould Iโd cut to shape them, which made them easier to glue and pin. I used J Perkins Aliphatic Resin, and the tiny Amati pins and โnailerโ โ which proved particularly challenging on the beech chine strakes
Overall very pleased with how this is going together. Now to find some paint!

Hey Michel-C
My name's Bill, and this one just needs a proper clean, and some new varnish I think - I may even wash the sails, but she sails nicely
Thanks for the welcome

I have a plan from the Aerokits/Keil-Kraft kit we built with our father many years ago. I'm restoring it too, and thought the plan may help you?
Good Luck with your project

๐ Float Test!

So having stripped out all the old equipment - see image of home made rudder servo! - I decided to check for leaks. I used some soup cans for ballast, and after around 45 mins found some water coming up the old 3/16" x 9" prop shaft.
Having asked advice on the forum, I need a new 5mm prop shaft, but will wait until I have the motor, before ordering one. I may need a different length, and now I know I'm opening the hull, I may as well fit a new metric rudder and tube too ๐ค

Thanks Everyone - I will need to change the entire prop shaft, as it is less than 5mm internal diameter anyway, and seems solid brass. I plan to install a new 5mm unit.

๐ Propshaft replacement?
6 years ago by

Iโm refurbishing a 34โ Vosper Fireboat, and as Iโm stripping it, have found the propshaft outlet brass โbushโ to be slightly worn. Itโs a 9โ brass tube, with a 3/16โ (4.6mm) x 10โ inner shaft. The outlet bush is worn to 5mm, and the input to 4.8mm. Iโm looking for some advice please. Should I just grease it up, and carry on; ream each bush out to 5 mm, and replace the inner shaft; replace with a completely new 5mm propshaft? If replace the entire shaft, how do you remove one without damaging a wooden hull? Thanks in anticipation! Bill

Hi, I think found a post from you around a year ago re a 46โ Vosper model, where you said your boat was โa bit fast at 11vโ. Is your boat noisy relative to others?

Thanks Elsrickle. I think you may have the 42" 12th scale model? I only have one motor, and yours seem to be very powerful. I'm hoping not to have any leaks, but am now wondering if my rudder and prop tube will be leaky - Maybe I do a test in the bath!!๐

Hi Martin555, Graupner told me to ask a supplier in the UK, or at a Model Boat Club - fair enough, but there are so many different opinions!! - 600 or 850 brushless being the most common. M-troniks recommended their G2 Hydra50, which I quite like the idea of, as they are UK based, and "waterproof". I'll do some comparisons of similar 1400kv motors, but as a beginner, I think it makes sense to use a "matched" system?

Hi Martin555,
Many Thanks for this - I'd not seen that post. I've actually written to Graupner and Mtroniks today to ask for a recommendation, so will see what I get back. It does seem to be a dark art for the inexperienced though!

Yes Peter, It's an Aerokits model - I still have the original intructions - distributor was KeilKraft. Scale drawing says 3/4" to 1'. Original boat was 46ft. I think that must be 1/16 scale? Model is 34 and a bit inches long

Thank you. I've started to look at other blogs, to help me decide how far to go with this one. I'm hoping to do the refurb over the winter, and install the new motor/servo and electronics, then remove, so I can do a better job on the inside, before doing the repair and repaint
