DIY Sprocket Sliding Door Lock

Need a quick and sturdy lock for a sliding door? Here's a brilliant

solution. Start by cutting a metal sprocket in half. Then,

weld a simple bent rebar handle to one of the halves. Once installed,

it slides perfectly into the other half, creating a secure lock.

Next up, if you're dealing with large pipes, a standard wrench might not cut

it. Create your own heavy-duty chain wrench by welding a section of a

sprocket and a sturdy chain onto a metal pipe. This gives you incredible grip and

leverage for those tough jobs. Don't throw away that plastic bottle top!
