Crank cases painted and cooked. Dry fitting to check both upper and lower case bolts all go in OK, which they did. Did the same with the sump yesterday and had to chase out one hole with a tap and found that 2 bolts need replacing due to damaged threads. Stuck another £200 in the bank of David Silver so engine rebuild can start soon.

The zinc plating looks good you're certainly ahead of me on the build!
I'm in pause mode at present - I need to get my threads for the cam horseshoe done but have temporarily run out of roundtuits. In a rash move I bought a spare engine for working on in 2022/3.

I have been very impressed with the Gateros kit and got good results pretty much from the off. I chose to buy their PSU to give me good control over current and I think this really makes life simpler. I use 0.1 A per square inch of whatever is being plated. At this current things come out grey rather than shiny, then they turn miraculously silver after a 30 second dip in blue passivate. This technique is recommended by them. I have found that by using a hot water bath with the alkali cleaner has also worked fine, it is recommended to get this much hotter by using a gas ring or similar. I Make sure that everything I plate is already mechanically spotless and degreased before putting in the alkali bath.

I've used Gateros kit for several years - works well. I use a battery charger with the basic current control. You just have to be well organised with all your various tubs of alkaline, pickle acid, clean water (for rinsing between each stage) and pasivate.
Why I like it is you can plate as you build the bike (in small chunks) - just follow the instructions!
