Preserve (pieces of) Pittsburgh's Roberto Clemente Bridge: 6 steps



Each year during PicklesBURGH, the City of Roberto Clement Bridge closes for vehicular traffic and opens it to pedestrians and businesses that sell everything traffic related.

And every year I take the opportunity to check out those parts of the tire that are usually only open to vehicles and harvest parts of the bridge that have fallen off. Kind of like collecting leaves.

Don't worry, I didn't use a pickax on the bridge. But if I see one piece, especially one with an iconic yellow color that is still attached, I collect it. By 2020, the bridge is undergoing a much sought after review so this may be the last time I can collect these bridge pieces.

I decided to preserve the pieces I have.

Lately I've had fun playing with cast resins. So I got some molds and enclosed pieces of the bridge around 201

9 in clear cast resin. They came out pretty cool! Here's how to preserve something special for you.

Accessories:

Here is what you need if you want to follow this instructional exactly.

  • Roberto Clemente Bridge – preferably off for cars / trucks / motorcycles. This is where you get metal bronze pieces. DO NOT CHIP PIECES OFF BRIDGE.
  • Gjutharts – I used Art & # 39; N Glow resin. Two parts, resin and hardener. It works well if you measure it properly.
  • Food Scale – all cheap food peels work. There is a bunch available on Amazon if you don't already have one. It is so that you can more easily measure out the right amount of resin and hardener.
  • Vacuum chamber – This is so you can get bubbles from the mixed resin. Fewer bubbles = clearer. You really need this if you want to see what you put in the resin. A kit with a decent pot with a pump costs anywhere from $ 100 to $ 150 USD. Amazon or eBay are good places to get one.
  • Molds – I used a combination of molds and will get into what I used and why later in the Instructable.
  • Mold Release – so your cast resin is not too firm to the mold. I use Mann Ease Release 200 but there is plenty on the market.

Optional:

Polishing application and a pressure can.

There are all sorts of ways and methods of polishing resin. Here is a very thorough instructional guide on how to polish the resin.

A pressure can is the opposite of a vacuum chamber, instead of pumping out the bubbles they squeeze them down until they are super small. Many swear by pots, but they are clever to set up initially so do your research.
