Limber Chains

I've got limber holes thru the stringers that my engine sits on. They get clogged so I decided to chain them.

First I had to cut away the tank platform to get access to the limber hole. I used a hole saw, then followed up with a multi tool.

I like to make the chain easily removable, yet captive. This translates to a chain with pins on the ends. I use plumbers chain - the all brass kind. The pins are spot tacked with a little solder.

Once installed, they work a little and keep the limber hole open.
