Rummaging through my dad's shop's attic
The door has a stand on the back so it won't fall all the way open. But I found if opened quickly, the stand would bounce off the floor and the door come shut again. So I added a box full of sand for the leg of the stand to push into. That eliminated the bounce.
This is the last batch of chairs my dad built in late 2008. He was already declining, and after that he stuck to simpler projects. Still, I was impressed he was able to keep track of how many of which part he needed for a large batch of chairs. But when I cleaned up the shop, I found a lot of unfinished chair parts. I think for that batch, he just made a lot of each part without really counting, then assembled chairs until he ran out of something.
This is the coolest thing of mine still in the attic. It's a little remote controlled fork lift. No batteries or electronics - I just ran it off a long cable. The stick sticking out the top was a "mast" for the cable, so it was less likely to drive over it's own cable.
The wheels are individually driven by a windshield wiper motor. The main lifting mechanism is made from two car window lifters (hand cranked ones). They are connected with a shaft in the back, and that shaft is driven by another wiper motor with a belt.
I initially built it in late 1985, then played around with it a fair bit in the summer of 1986, moving pieces of firewood and boat anchors and such. The only limit to its ability to lift was that it would tip over forward if there was too much weight on the fork.
I originally built it with wheels, but after having success with my tracked vehicle, I upgraded this one to tracks as well. But the tracks ended up having way too much side-to-side traction on the grass, so it became impossible to make turning manoeuvres. So I took the tracks off again, but left the sprockets on because they had much more traction in the grass.
This toy hasn't run since 1986, but in 2006, I took it to
my shop and got it working again.
I also made a video touring around the shop and where the old
sawmill used to be:
