I need to come up with a right angle gearbox (example)
I’m not a blacksmith and local hardware stores are coming up empty apart from selling a right angle drill attachment (which would work but they’re a bit pricey for my purpose).
The purpose: to hide a water valve (positioned upright) & control it from the other side of a wall. (back story)
My ideas so far:
- find a broken angle grinder that someone threw away (seems unlikely) & cannabalize the gears
- build right angle gears out of wood
- harvest worn down bicycle cassettes from the trash and orient them at right angles against each other. They are designed to mate with a chain, so I’m not sure how well it would work. The valve is only turned on/off a couple times per year, so maybe I can get away with it.
- go to a toy store and find a kid’s Capsela set (do they still make these?); though I imagine it might exceed the cost of a right angle drill accessory anyway and it would possibly break under stress.
What other tools or appliances should I look for on a dumpster dive which would likely contain a right angle gearbox?
@lettruthout No I haven’t. Interesting idea.
I would like the hole to be as small as possible. I have a solid steel rod on hand (ø=12mm) but I could even get a smaller one. This would be the least intrusive on a structural wall (brick), which technically I’m not supposed to touch without planning permission. I would bend that rule for a rod ≤12mm. I’m not sure if removing a whole brick is bit risky since it’s an old house and the state of the brick is probably dodgy to begin with.
