Just think Studs, you'll have all the time in the world to fix the gear box now on the auld one 

 

I'll believe that when I see it 

 

Did Wicky have a spare gearbox in his collection of bits?  Although when I thought about doing it the biggest cost was the gaskets. 

[dapleb]

I have plenty of grrr box bits. As ewe say the main cost is in time/gaskets.

Look forward to meeting up with you in the summer Studders, you on day and me on No7.

 

Sounds like a plan Alun

Unfortunately, the old one will be moved on as I plan on replacing it with a 9'er.   I've got a spare gearbox for it, somewhere.

Joining the pink side again then Studley? , get a niner save the mk1 for special occasions ?

I reckon it's the start of his TDM shed museum.

[leehenty]

So he needs Mk2a to complete the set

[dablik]

And so it begins, Sidey 2

Looks like it Lee. Yes, Meoff will be for dry days.

Hmmm, I'll prolly stick with 2 TDM's, but ya never know.

I roh rink roh ! 3, maybe 4, don't have the room or deep enough pockets.

 

Made a start on de-rusting the fuel tank.  Watched a few oohtoob vids and decided to try Electrolysis Using Sodium Carbonate.  Unfortunately, it's not easy to get hold of but, one can heat up Bicarbonate of Soda to around 200C and it'll turn into Sodium Carbonate. Weird watching it happen as the powder bubbles.  I've got a battery charger, 12V 6Amps RMS which can be connected straight to the Anode and Cathode.   The voltage sensing automatic chargers also require a battery to be used.

 

Ken was right, the tank is very rusty inside

I bought some steel bar to use as the Anode and got to work.

It soon became apparent that my charger wasn't that powerful and it was going to take a long time to do.

48 hrs, and a couple of Anode cleans and it's looking better

But still more to do.  I then used some small pebbles and shook them around for a while, took fookin ages to retrieve them.   It helped a bit.  2 days of more electrolysis and the tank is virtually rust free, just a stubborn patch and some running along the seams to remove.  I might bite the bullet and get me a 24v charger, it'll come in handy.

Neat trick!

[dapleb]

Looks a lot betterer that. Seems you have the knack sorted but if not i know electrical dept does this often and also nickel plating.

[leehenty]

Sodium carbonate is washing soda, I use it to clean up after anodising making sure any acid drip's are neutralised. Less vigorous than sodium hydroxide. That's a neat solution, are you going to seal the tank ? If so try Frost Auto restoration they do kits. May I suggest a variable power supply so you can limit current to whatever you want. Modern switching mode kit is quite reasonable these days.

You mean summat loike this Lee ?  https://cpc.farnell....able/dp/IN08000

 

Should I be going for more Volts or more Amps to remove the rust quicker ?

 

I think this tank won't need sealing but the XJ650 one prolly will.  Thanks for the recommendation.

[leehenty]

More amps as surfaces area of tank is large.

Perfect    Early xmas pressy for me

[leehenty]

There will come a point when the resistance at the other electrode will become a function of surface area so currents will stay the same no matter the voltage. Anodising it does this as the hydroxide layer builds

Using my battery charger, I noticed the amps drop as the sacrificial anode builds up with rust.  A good clean and the amps increase. After 4 or 5 sessions, when there's very little rust remaining in the tank, the amps are much lower.
