IN THE BEGINNING there was what looked like a pile of rust😲
which got soaked in WD40 for 24 hours!
After washing off with warm water and washing-up liquid, and drying in the sun for a few hours, the bearings (and copper wire brushes) were oiled, missing connecting links bridged, and 6V (with current limit 3A set) was cautiously applied. Lo and behold she rattled and protested BUT RAN! Oh! That nostalgic smell of ozone, and enough sparks to read a book by🤔
Next connections were changed, to separate field and armature coils (brush gear), and connected to a standard brushed motor ESC (Graupner Navy 30A) via my prototype converter board, and a Robbe Servo Tester to simulate TX and RX. lo and behold chapter 2; she ran forwards and backwards😊 and no sparks!
Now dismantled (last 3 pics) to start clean up and replacement of corroded parts. Sorry Col, I broked your motor😁😁
Armature was cleaned up and commutator polished; surprisingly lots of 'meat' on it so motor has not been run much.
Next stop; lathe to make some new frame spacers.
After that new bearing bushes cos the old Paxolin end plates have worn so that there's about 1/32" slop!
Will probably have to turn the drive shaft down from original 1/4" (6.35mm) to 5mm to remove last traces of rust and pitting.
Cheers All, Doug 😎

Wow Doug, you're a star and letting you loose on my motor proves it.
Thanks for taking the time and trouble to restore the rust heap into a useful working motor once again. I better get on with sorting out my dad's old sea commander ready to put it in. By the way the BA spanners are on the way via normal post.
Cheers Colin.

Thanks Colin,
In the process I've probably destroyed much of it's vintage value to collectors, even though so far I haven't had to replace any parts.
But I did ask! So I'm restoring it to a working unit as requested.😉
Two of the longer frame spacers are now a bit slimmer 😲 after turning most of the corrosion pits off, but useable.
Could salvage all aluminium spacers except two of the short ones which just crumbled to dust.
I'll make new ones tomorrow or probably Saturday. Tomorrow is a busy day, optician (new goggles), and photographer (new passport photos!), shopping (man's gotta eat sometime😁) and then dinner with the GF. It's all go folks!
TA much for the spanners Colin 👍 will be very handy for the reassembly.
Looking forward to seeing the motor propelling your Sea Commander across the lake. Don't forget 'The Beast' weighs about 950gm, bit less now that I've removed most of the crud of ages😁
Cheers, Doug 😎

Evening Doug,
Just a thought, as this motor has shafts either side of the motor, I was thinking of fitting a fan on the non-drive end for cooling, would this be feasable or isn't it likely to be needed.
Cheers Colin.

Hi Colin, sorry nearly missed this.
Don't think a fan will be needed for the motor, max current should only be around 5A and it's a hefty chunk of metal.
BUT it could be useful to cool the ESC and especially the bridge rectifier in the converter board for reversing the motor.
You will need something with a 1/4" 'ole in the centre.
Cheers, Doug 😎

Great Doug, if you need material for the bearings let me know, did wonder about ball races? But you know me full of useless ideas. As sinatra said you do it your way. Cheers Colin.

Interesting restoration project . Great fan of Taycols myself though its some 24 years since I had one.

The motors themselves are bristling with character as you can see the armature rotating and you do get the smell of something electrical along with it. Taycols go further than being just power units as they are good ballast due to their weight.

Unfortunately through progress they have been replaced by little tin cans and brushless devices. Hopefully someday a person or a company will put them back in production due to the number of retro boat kits now being sold.

Wholeheartedly agree Boaty, my fleet is made up of vintage boats which I love reviving, most of them were donated to me over the last 4 years my wife and I both enjoy sailing our boats and trying to encourage younger folk to try it. I have no problem turning over control of my 50 plus year old boats to total beginners of any age, the youngest so far is my grandson who started on his 3rd birthday with a small rc boat I bought him. Now at 4 he's getting quite good and learning learning manoeuvring with my large tug Valiant which is just over 4ft and pushing 60yrs old. I have never been tired of those that are willing to learn and have a go. BTW The supermarine is mine and I am going to be installing it into my father's old sea commander built in 1957. Originally had a diesel, but the taycol is the ideal replacement. And with Doug doing the rebuild on it I will be able to use it with my modern rc system.
Cheers Colin.

Evenin' Colin,
Thanks for the offer. I'm going to use some stuff the Martin sent me, called Chrodite apparently, although I can't find any description or reference to Chrodite anywhere! Looks like brass with an extra ration of tin.
Supposedly harder wearing.
Anyway, stator and frame spacers etc are now finished.👍
So after feeding the inner man I'll start measuring up for the bushes and see what I can do about tidying up the drive shafts.
Have just sorted out a 'Live Centre' for the mini lathe which should help.
I want to hide the bushes inside the original Paxolin cards and the external end plates which contain the felt oiling pad. So ball races are out of the question unfortunately; too large diameter and too thick 🤔
Needle roller bearings would be nice, but I ain't got none that small😭
(Nah, admit it Doug you ain't got none at all, they're way too expensive😭)
Amused myself today polishing up all the brass nuts and bolts!
Confucius he say "Polishing nuts - very painful" 😁
Weather should be good for spraying tomorrow so I might fire up the compressor and give my PTB a blast of Pacific Green. 😊
Cheers All, Doug 😎
BTW: where are the pics of your Avanti? Harbour posts without pics are pretty dead 🤔 Cheers, Doug 😎 Oops! This doesn't belong here!🤔

Hi Boaty,
The Taycols have fascinated me as well, ever since I dug the Target out of the Sea Scout my Dad built in the early sixties. I blogged my renovation of that and the conversion to run with a modern RC system and presumably that, and the converter boards I built for Martin (Westquay), is what triggered Colin to ask me to have a look at his Supermarine.
How could I resist!? 😉
The 'smell of something electrical' is the ozone gas caused by the prolific sparking of the Taycol metal to metal brush / commutator combination.
The other source of Ozone is on the coast wherever there is a strong surf!
I agree, a nostalgic smell, which unfortunately disappears when the converter board is attached to make it run with a standard brushed ESC. The diode bridge kills almost all the sparks. 'Almost' so the usual suppression capacitors are still recommended. 0.1µF across the brush terminals, 0.047µF from each terminal to the motor can, or frame in this case. Earth to prop shaft tube as well if possible.
The motor may not disturb the on-board electronics of your own boat, if using 2.4Gig, but could still affect anyone nearby using 27 or 40Megs. Like me and other submariners for instance; 2.4Gig is useless for subs cos it don't go underwater. Cheers, Doug 😎
But here!

Hi Doug, I also can't locate chrodite in any bearing material listings. I have some phosphor bronze in my workshop if it's needed.
Cheers Colin.

Hi Colin, sintered PB would be my first choice. Let me see how this mysterious Chrodite turns out. I'll let you know.
Cheers, Doug 😎

Hi Doug, if you want iolite bushes, they are available on ebay, just say the word and I will order the size you need. Cheers Colin.

Chrodite!! Blimey I thought I would never meet another person who knew that word.
My friend had a load to make fixings for his tiny, but lovely Crouch sloop White Mouse. He gave me what he had left and I'm down to about a foot left, so that goes towards making prop shaft bearings, so, Doug, you've actually got a wee bit already.

Age related. Completely forgot I'd sent you some. So that's where it all went...haha, only kidding. I can't think of a better use for it, matey.
