    Multitools

    Yeah, I wouldn't consider combining very many tools to the same component, and the outer lock that locks the smaller tools placed next to each other might be tricky to add with such a small pivot pin. However the linier locks are more simple and robust as they are part of the frame. For a screw...

    Multitools

    I've completed my model on fusion for my first multitool I want to attempt to assemble. I studied one of my old multitools for a good idea on how the device works to hold and lock all the different tools into the frame. It's not too complicated, mostly just a series of springs that are part of...

    Sourcing Metal | General Discussion

    I've been trying ro find some fairly thick stainless steel flat bar and plate. I plan on putting together a stanless steel multi tool. Most tools would be made from some 1/16 - 1/8 inch tool steel or high alloy stainless steels depending on the tool. Those are sold where I buy my knife steels...

    Oxy fuel brazing brass

    After filling my Argon tank, I spent a lot of time tig welding, or in some cases, tig brazing the brass with silicon bronze filler metal. It's difficult to apply the filler metal as the brass melts before the zink starts to boil. If the filler is built up along the joint it will bond to the...

    Being heavy brass Im thinking it would probably be best to tig weld it together; but I am out of argon.

    Oxy fuel brazing brass

    There is a big difference between brazing copper pipe or thin brass stock, and brazing heavy brass or copper. You need to heat almost the entire peice of brass to bring it to the right temperature, and the amount off heat that is built up in the stock is much higher than any flux will melt...

    Oxy fuel brazing brass

    Ah, I figured it must have been because of the lower temperature of the base brass. I was brazing the parts of the hilt and guard of my fantasy sword that were recently cast. They are all about half an inch thick so it was very difficult to bring both parts to a high enough temperature by how...

    Oxy fuel brazing brass

    I'm really struggling in just brazing heavy brass. It's said that the process is just the same as soldering with a torch. I tried using flux paste, as well as flux coated bronze brazing rods; and it's easy enough to bind the solder as that is all that melts; but unlike silver soldering it does...

    Casting sand

    I just picked up sand casting to use for casting brass. I built a strong metal flask similar to the cast iron flasks you see on Amazon. I needed something bigger, and didn't want to go into making it out of wood and see it burn so I welded together a flask made of mild steel. Petro bond casting...

    UV Resin and a custom machined cabochon for a fishing reel

    That's really nice! I've never thought of putting a anything on display under a transparent cabochon. That is a great idea! Even with a real gemstone, If the clarity of the stone is clear enough, the beuty of the stone's color could realy add something to a design like an engraving underneath.
