Wow, thank you Amateur. I didn't even know you could do this at home. By the way, I thought that such things can only be done if you have some kind of engineering education, but it turned out not. Only I have a question, where can I buy such spare parts? I recently Googled and came across only this site spam link removed. Who can advise me on some other options, and preferably cheaper. I don't necessarily need new parts, I can also use old ones, as long as they are in working condition. Thank you in advance, you're a cool guy, keep it up.
