I'll let you know in exchange for a bodywork set when they're ready!

Cheers

Default derusting

Hi all one thought on drusting parts ,if you know any one with a saftykleen degreaser,they do a liquid derusting soloutin which we tested for them at work,i thought it was going to be a gimmick, but it was brilliant and did what it said on the tin all you do is drop the part into the solution and leave it do its stuff .

Cool electrolysis for beginners

Guys I found this website from the USA.

http://users.eastlink.ca/~pspencer/n...ctrolysis.html

Very good, explains why it works, what you need and what not to use.
Even suggests using a battery with the charger which helps the process and stops the parts/ charger causing problems for the charger and part being cleaned.

When I have my donor car then the soda crystals will be well used for this little project.

Happyjo

I made myself some washing soda (sodium carbonate) by heating baking soda (sodium bicarbonate) in a stainless steel pot. It's weird to see dry powder boil, giving off gases.

Baking powder is a mixture of sodium bicarbonate and citric acid, it is too acidic.

i believe you can use a higher voltage/amp to get fast/better results, therefore i am going to attempt to do it with my ark welder.

has anyone used the bath and welder setup?

Personally i wouldnt attempt to do it using an ARC welder. The power output is massive and if the current goes through you then it'll stop your heart, not worth it to save an hour at most....

Agreed - don't forget the hydrogen that is produced by the process, one spark and BANG!

I'm a big supporter of grit blasting rather than other methods for rust removal. CKC mag ran an article this month that said that it was unsuitable for components that are fragile or have extensive corrosion. Well, if the rust is that bad - would you really want to use that part anyway? Blasting gives instant results and leaves the part perfectly prepared for repainting. Although I should mention that it is critical that the part is given some surface protection within a couple of hours or rust will set in very quicly, as the process greatly increases the surface area of the part.

Machine mart sell a small cabinet for 118 but it realy is a worthwhile investment (provided you already have an air compressor). It can also be used with glass beads or walnut shell. If you have larger parts to clean, it may be worthwhile asking your local metal plating/galvanising/wheel restorer company for a quote to blast them for you.

Having said all that, electrolysis is a cheap method for doing a small number of small parts. And I guess we are all building a sports car, on a budget.
