I Made a Catapult



One more thing to check off my bucket list, I now have both made and fired a piece of siege weaponry. A trebuchet to be exact. A couple of bed frames, bits of channel stock, a dirt bike chain, freon tank filled with water, an old rim, and some parts from a treadmill. The arm is on a ball bearing pivot and flings things ever so smoothly. The farthest shot thus far is about 60ft, but I'm hoping to improve that with a proper sling and a couple of heavy old batteries for the counterweight as soon as I get some from work. It's still a work in progress, but it's pretty awesome even as it sits now at roughly 12ft tall. Once I get it really tuned up maybe I'll post some videos. You can also see Mighty King Tiki Toki Tookie behind me too.

EDIT: I've vastly improved it with two large truck batteries for a counterweight and a sling instead of a simple hook. It now slings objects about 150ft. Also, BRIGHT GREEN!

I Made Dogs


Nuts and bolts dogs, made the same way I do the model motorcycles. Burnt my left index finger pretty well on one of them. Springs are very hard to weld without melting them and I'm amazed it was so hard to find 8 matching bolts of the right size when I have so many that are all very close.

I Made Motorcycles

Well, a model of a motorcycle anyway. Gears, a ball bearing, and some various hardware bits combined to make this fine little bike. I forgot to add foot pegs and exhaust pipes, but I may go back and do that. To give credit where credit's due, I got the idea from these guys in Thailand. They're really talented. It's about 20cm (8") long.

Edit: Made this one too.
