This is very nice. I was impressed that this works for the inner casing. I always did not know what to do with this. Modern lanterns have it...
Thanks @podbros but I do not think that plating will work, as the metal is not completely clean. Unless it is possible to fully clean it with what...
If they are rust as you say, why a rust remover or even better a rust converter (like tannic acid) will not stop the corrosion? My issue is not to...
Good idea. I will ask them.
Thanks. I looked everywhere. These products are very rare in Europe, and if you find them in some country (eg Dupli-Color Silver Brake Caliper...
Can you give me an example of a product so I can find a similar in the local market?
I tried to remove rust with citric. I applied many times until it was possible to remove the last rust with sand paper. After sanding (by hand)...
Thanks. I will examine my options...
OK, let me ask something else. The plate I picture above (#122) needed several attempts to remove rust. It was too rusty. Now this is magnetized...
Just out of curiosity, even if the brass surface is nickel plated as this lantern is, will again vinegar etch the zinc of the brass below nickel?
OK thanks. I will see what I will do. Maybe better to avoid acids on the tank and insist on petromax polishing paste...
Great. So I will proceed with some acid. Question: If acid (like vinegar) is applied to the tank which is nickel plated is this dangerous for the...
Correct, thanks. Part 122 the centering bottom gets magnetized and it is very rusty as you can see below. I tried using sand paper (as you can see...
I was wrong about rust in the bottom of the pump cylinder. It was old oil deposits from the lather of the pump. It looked like rust, it wasn't....
The trick with the drill worked fine. Brass is now visible inside the cylinder and feels very smooth. At some points though there are some red...
Nice trick. Will try this first after soaking in WD40.
You mean (I guess) something like this:...
What is a "brake cylinder hone"? Never heard this. How bout using fine sand paper after the soaking with WD40 say for 2 days?
OK, I will try that with WD40 and see how it goes. The tank inside looks clean. I also washed it with water and water came out clean even the...
I got an old 250 from the web. I know my way with Petromax but this problem had not occurred to me: I removed the pump piston and lots of rust...
