That looks like an interesting process. As I understand its a solution of sodium bicarbonate in water ? What concentration of powder do you use please ? Which terminal is the anode (+) and which is the cathode(-) ? How much current does it take and how long does it take to remove all the rust off ,say , a lower suspension arm ? Do you get any gases released during the process which means it has to be done outside ?
I'm full of questions today ! :)
Thanks very much,
Tony.

Yes, it is sodium bicarbonate in water. In this test, (it is my first time testing it), i used 200g of sodium bicarbonate in 50 liter water. IMPORTANT!!!!!! Use the :!: NEGATIVE :!: pole connected to the parts that you want to clean.
I used a 12 battery (like the one you use in your car) and with the charger connected.
The 4 parts shown on the pic, i left in the water for about 2,5-3 hour, next time 4 hour :lol:

CHEERS :sozzled:

This was fun :D :D .............. I'm surprised at how good electrolysis works ...... threaded areas are also like new.
I restore 2 complete front suspension, so I use the best part of the car, and the rest in reserve.
Also got hold of a spare sprint engine, original engine is overhauled to the original standard, the other will be a race engine.

Thank you for all the useful info; on this . Much appreciated. I have just tried this out on a small scale with sodium carbonate - ( its all we could find ) -about 50 grams in 3 litres of warm water in a plastic bucket with a 12V car battery float charged from a battery charger. I used a tin can as the anode (+) and an old rusty Dolomite handbrake lever as the cathode. A couple of things to note: the current consumption is about 2.2 A and I put a 10A fuse in series just for safety. The solution of the carbonate does get quite warm after 2 hours. It is necessary to stir the solution around from time to time as the current drops off.
After 2 hours the metal comes out looking really nice and clean.
A very worthwhile process.
Thank you for the tip,
Tony.

A little something every day.... 8)
Now the welding on the front done, only some minor welding left.
Also mounted the accuspark kit-5 ignition to my lucas 44D4 dizzy.

...just read all 5 pages of this thread with about 6 cups of tea ( ..insomnia - its a curse! :lol: )

...anymore progress?

....altho, in the UK, we have a mild amount of snow - and it freezes everything and everyone -
I just bet its colder where you are...?

.......you must have a VERY large heater in your garage...???? :lol:

oh yes ....... cold as hell here in Norway, about -10 degrees celcius.
In the garage, however, never below 15 degrees. No need for BIG heater, garage is fully insulated :) :).
Progress?, Trying to do a little every day, but do not hurry. This car will all be done properly, and it costs money and takes time, as we all know it does with old cars :) Have bought an ultrasonic cleaner that is fun to play with :) :)
This is the first triumph I own, which has 4 wheels. Disassembled carefully, restoring parts gradually, and packs away well.
Now the body is completely empty, the next to be done is to create a tripod with wheels, so that it is possible to move it to the painting in the spring / summer. (depends a little on the money available).
Photos coming :) :)

oppps I missed something here...

Is that a definitive on a particular leccy ignition module that works with the Sprint oem cap and rotor?

The pics dont look like a sprint rotor arm and the 45 D type, which that looks like, doesnt work with the sprint cap....

Thanks for the replay:):)
I understand you've done your homework, and you are hereby passing triumph dolomite exam.... :lol: :lol: :thumbsup:

I had to cut off the top of the shaft by 1-2 mm. This to get the rotor from Lucas 45D4 far enough down, so sprint cap should fit. The oem sprint rotor is too big, won`t fit.

Lucas part number 54422803.... :robin:

I'm sure there is a rotor arm similar to that, that will fit straight on. I think it was from a Lotus something or other (Elan?). I think it was Carl who told me that a few years ago. :shrug:

I think the lotus engine (cortina,elan,europa) use the 45D4 dizzy AND rotor.
The only different on the "lotus" dizzy, it dont have any vacuum.....
I used to have a lot of cortina in the past, when twin weber fitted, i have to use the "lotus" cap because of the side exit.., and block the vacuum :wink: ...... I dont think the lotus got a different rotor...but i am not sure :roll: I know SOME lotus used Lucas 54412165, but i think this is just because of the rev-limit.

Mad Mart : What do you use in your trackday sprint??

I recently used your electrolysis rust removal on a pair of Sierra calipers I got from a scrapyard for my TJ conversion. I have a variable power supply so I set it at 12V and 2.2A and left it over night - the calipers were really rusty when I got them! Rather than using bicarbonate of soda I employed washing soda (more concentrated and cheaper) - it worked a treat so many thanks for passing this technique on. Good luck with the resto I really enjoy the thread and the other restos on here a really interesting and good way of learning things!

Dave

P.S Note that the gas that comes off is Hydrogen so no smoking while the cleaning is in progress!
