This morning I went to the local DIY-shop to look for a burner and some silver-solder. The cheapest items that I found were pretty expensive. The burner costs €23,- and silver-solder was about €7,- (about $37 together). It’s a lot of money for one simple elevator assembly. So I went for plan B, and bought a tube of Bison Metal Epoxy. Maybe this will work out as well. It should be resistant to vibrations and could cope with a lot of stress. We'll see. I'll test it firmly before mounting it on the Stiletto, but I think the M2 thread is going to be the weak link... If it isn't quite meeting my expectations I will solder it though.
The ingredients:
First I'd make small cuts with a wire cutter to generate more grip. Then I'd grind all components and clean them with some thinner. Afterwards I'd add the Metal Epoxy onto the parts and wrapped steel wire around firmly to give it extra strength. After adding another coat of Metal Epoxy on the outside I was quite confident that this is going to work out, don't you think?
