Evaporust Trial on fuel tap front plate.
« on: September 08, 2020, 08:57:37 PM »
In the first picture is my dismantled Petcock the second is after 5 hours in a plastic takeaway container of Evaporust about 5mm depth of fluid. I've only put the thin plate in to clean at present.
I did lightly brush the surface after 3 hours to try to speed up the cleaning.
Naturally it can't fix the loss of the surface coating but it's pretty impressive.

Impressive! Good plan to (at least) try restoration of the petcock - always sad to unnecessarily consign old stuff to the bin - as I keep telling the daughter 😂.

You have to plate them as, it will go rusty straight away.

I have a zinc plating kit (had it 10 years and only changed solution once - just bought another as the recent finish is getting dull) - I zinc as I strip and refurb so its not a big job and everything is ready for reassembly when required.
I've had good results and zinc on bike I built 10 years ago (ZZR) still looks good

I used these guys for a plating kit as there support came well recommend. Preparation is the key and a controllable power supply as you need to be able to apply 100 mAmps per square inch of surface. Plating in winter can be a problem as getting and keeping everything to temperature is a bigger challenge as you will need good ventilation as well.

Macabethiele, just something I found after putting in new rubbers etc, the tap was very stiff to turn against the spring washer, even with some lube, and I put in a little ‘Weldtite TF2 white lithium grease 40gm tube’ that I use on my cycle and now it’s remained very smooth.

I purchased a basic kit from same company and had reasonable results, difficult indeed to maintain liquid temp. I was wondering about a propagation mat, some are thermostatically controlled. Or just set up in nice warm kitchen!😂😂😂

I ended up with everything in water baths and added boiling water to get the desired temperature.

I use aquarium heaters in mine with insulated buckets to get the temperatures correct.
I have hade some great results with the basic kit bought through Classic Plating.

Sorry, just seen post - same company as already suggested - https://www.gaterosplating.co.uk/index.php?route=product/product&product_id=231
I also use an aquarium heaters and themometer to sort correct temp - to be honest, its only in the winter I bother with them as in the summer, its 'near enough'

Thanks for that Phil - as I keep tropical fish in my outside fishhouse/garage office annex the temperature will not be an issue.

Spent most of yesterday zinc plating various gauge parts. The gauge bases take about 45 minutes at 1.25 volts.

Good advice on the tank heater, the plating solution needs to be 25-30 centigrade and putting a small bottle of hot water in the tank will help getting the temperature up as the tank heater can take a while to get it there. Bandaging the anodes is a help in stopping small particles of zinc getting into the solution and onto the item being plated.  Filtering the solution when finished with it keeps it clean and two coffee filters in a funnel works well but takes a while to run though.

A power supply is essential although some seem to manage with one of those resistance wire arrangements.

Just as a bit of a trial I tried zinc plating a brass bezel. I didn't prep it very well just wanted to see if it would plate.  Came up quite well and now I regret the prep wasn't better.

I've only ever used the variable resistor thing that came with the kit and a battery charger - can anyone suggest a variable power source that would do the job?
