The coilspring powered crossbow is, for thesizeof my Youtube-channel, very popular (so far over 800000 views). Because I was expecting that already shortly after uploading that video and because I wanted to continue on the topic anyways, I had started with a bow using the same principle, but improved with a "compound bow cam system" with non-circular wheels and other improvements I thought about while building the crossbow. As often it took longer than expected, also because of longer breaks through out the building process. But here it is now, the third version of the coilspring powered bow, which looks better and has a much improved performance. If you want to know and see more, check out the Video and the article in my DIY Projects. Including drawings.

I got a bucket full of rusty old tools a while ago. In there was a large hammer head with no handle that looked a bit taken by time. I decided to make it nice again. Real nice. So nice you can use it as a mirror. And a new handle of course which is not just made from wood but also with lots of brass. It all comes together to what I think is a cool reinterpretation of Thor's hammer Mjölnir, if real materials would be used and real "wieldability" would be considered..

The coilspring powered bows gathered some attention and thus I followed up the idea with a crossbow that also uses coilsprings as its energy source. It works using a different principle though. To get to see and know more, watch the Video, and/or read the article in the DIY Projects. Including drawings.

After the short "Teaser"-video of the 3D-printed Pantographic Letteropener now here the presentation of the so far final product. Made with a proper blade from spring steel, parts of the mechanism from cnc-machined aluminium, scales on the handle and other smaller parts 3d-printed. In addition a lot of manual work and a total of 3 prototypes, over 8 months total - and the result is I think the most professional and best looking project I have ever made real.
