Hello and happy 22.
I got some work done over the holiday, mainly on the engine blocks. I also got me a zink plating kit that i have experimeted with, with both good and bad result.
And let me not forget the valve cover, it can make a grown man cry
I have made the base work and it is starting to look good.

So got me a soda blaster, (thanks Nils) it helped a lot by getting into all the hard to get to places. The halves are now almost ready for paint. I have tried the paint on some smaller pieces first to see how it will hold up. When i have painted the cases the engine will start to come together.
The cylinders and head is at a local vapour blaster. I didnt now it but he is just 15 minutes away from me. In hindsight i should have got there with the blocks also but better late then never.
I tried the soda blaster to the head but the color was so tough that it would have taken forever with my (probably to small) air comp. The cylinder was 70% clean but it was hard to get everything clean. I will get these parts back next week.
And my zink plating career had a rough start
Before the actual plating i put the bolts etc in to acid to take away the rust and grime. Here is the exhaust flanges (in lack of a better word)

followed up by a failed plating. I waited to long to get them in the bath and they flashrusted on me, i wont make that mistake again.

Last is the pic of the finished plate job, these were after zinkplating dipped in to a yellow phosphate.

If the surface was better from the beginning i think they would look like new. The picture doesn’t do it justice, the yellow, gold is more obvius in real life. Note the flange in the back. The parts are supposed to be in the yellow phospate for 2 minutes. This one i found when i emptied the bucket som 15 min later….
I also plated the exhaust nuts (??) and some engine bolts. Think they turned out pretty good.

And at last my super duper f..k up
I put a lot of bolts and nuts into the acid, what i didnt now was that one of the bolts that hold the oil hose between the block and the head has an alu insert……
Acid and alu is a no go
Here is the bolt before:

And after:

I guess i have to contact Louis again…
A new insert could be made in a lathe and pressfitted in to the old bolt but a dont now if i will take that risk on a 20euro bolt on this bike.
Also the zinkplating looks kind of dull but with a brass brush they got som shine to them. I have come to the conclusion that its better to plate fewer (??) parts then to load it up to the max. The result is then much better.
I would like to have seen my own face when a took said bolt up from the acid
Hope you got some laughs
I have a question also, how do you experienced boys plan a resto?
My initial plan was to take care of the engine first then the forks, brakes, fram etc. But when i am on a standstill with the engine i am hesitant to start with something new because i dont want to start on a lot of objects and then never finish one. (Wich i sort of already have done:)
Do you strip the whole bike down to pieces? I can se the ups with having the frame done and start to bolt on ready parts.
Thanks Marten
