    Some more updates on this. Please, let me know what you think.

    Pattern Welding Explained

    I first saw this at Schloss Gottorf many years ago and was inspired by it:

    I just posted another thing I am playing with on Twitter, I am not sure if the forum software will be able to understand it:

    Building a Metal Dust Collector

    I have filmed welding before. It's just takes a lot of effort to set it up. Check this out:

    Do you have a pointer to a welding lens? First time I have heard about it.

    What did you do in your shop today?

    I got to test run my metal dust collector today. The Thien Baffle I built seems to be working alright at least it seemed that the dust collected in the bottom of the machine rather than being blown out:

    Building a Metal Dust Collector

    Here is part two:
  8. A lot of us spent a lot of our time in front of the grinder. I ended up getting myself a powered positive pressure respirator to breath clear air. However, the metal dust from the grinder gets everywhere. There is no surface in my shop where I don't get dust. On the other hand, dust collection for metal is surprisingly difficult. Many here use a water-based spark trap which also gets really messy. I found myself with some spare time and the desire to play with sheet metal. So, I am starting to build my own metal dust collector that does not require any water. As usual, I put this exploration on video. So, far I have built a Thien Baffle. Let me know if you have any advice or feedback.

    Thanks for the pointer, Ric. I had not seen that yet. That's really good.

    Pattern Welding Explained

    This is blatant advertising of a commercial offering. So don't read further if that upsets you. I liked the pictures I had shared above and wanted to make a t-shirt and a higher quality printout of them for myself, e.g. something to quickly show folks to explain some aspects of pattern welding. While doing that I figured I might not be the only one who would think that neat and put them up on RedBubble for others to buy. Here are the final pictures I came up with: Ps: I do get a commission for orders placed. As I have worked on this for almost two years that does not seem unreasonable :-)

    I am getting to a place where I am happy with the visualization and can now focus more on animating the process. It's still going to be slow though.

    They are computer generated :-) I plan to make a fully animated video that shows stacking and twisting, etc. BTW, I am still looking for more people who would like to share photos of their pattern-welded blades to be included in said video :-)

    Sure. Here you go.

    Pattern Welding Explained

    Here is an update to show where I am currently at visualizing pattern development; some of you may recall this from a paper from Ypey: Let me know what you think about the current look. BTW, I am still looking for more examples of pattern welding in the real world. If you have any examples you would like to share, please let me know.

    This came out great. Thanks for sharing! Looking forward to how they look when you are done with them.
