Finally
I really appreciate your presentation and also today I came to know about washers which can be used to secure seed phrase although it will be very difficult for me to have washer in my village but that not withstanding I can use something else to secure my phrase and also present it here. So don't be confused. I am your boy that always learning from you.
If washers are difficult to find in your village, then this is not a problem. You can print seed phrase on any pieces of metal you can find. Ideally, it should be stainless steel, but you can also use aluminum, copper, brass (only given that these metals are subject to destruction under certain conditions, which means they are not suitable for storage for a very long period), etc. Washers are just a starting point for your imagination, which gives you an idea of how you can save seed phrase. There is a wide field for creativity and experimentation. In the absence of washers, a square, hexagon or other shape can be cut out of metal. Drill a hole in the center of each such plate and connect them with a bolt and nut. On the free areas of the plates, apply the text you need. You didn't have any problems engraving text on dumbbell discs, therefore, if you wish, it will not be difficult to implement the method I proposed.
As i can see in the picture, you have painted over the text on the disks. This is certainly good for safety, but it is not clear to us on this forum what the result of your labors looks like. Could you show at least 1 random letter so that bitcointalk community can appreciate what the seed phrase engraving on gym discs looks like?
