Zinc replating

<< < (2/2)

If you want to strip it the pro way chemically use this (all available cheapish of eBay).  I bought 1kg of EDTA today of eBay. I use the same place for plating as Julie  and he positively loves doing my stuff stripped with this brew.

To make up 1 litre of stripping solution:-

100 grammes ---  Sodium Hydroxide  (Source Poundshops, B &Q, Wilkinsons, ect)

90 grammes --- EDTA---- (EthyleneDiamineTetraAcetic acid)  Source eBay

4 grammes ----  Triethanolamine   ..........Source eBay

Immersion is at 70 degrees C +/- 5 degrees for about 20 minutes (basically until the bubbling stops).

Slow cookers are mega cheap (Lidl, Aldi, loft  ;D) and will not overheat the solution on max. setting.

Specify if you need passivate finish either Gold chromate or bluish tinge clear (example of gold chromate are  regulator cover, spoke nipples). Sometimes you get black passivate. Examples of black pass.  are 'D' spacer washers on 500/4 & 750/4 top yokes and the earthing covers on USA 500/4 rear indicator brackets. But the bluish tinge passivate is used for most parts.
