Scores of carpenters met under the Interstate 5 Bridge in downtown Portland on Labor Day to raise money for the charity Oregon Tradeswomen Inc.

The so-called Dropbox Derby involved 27 teams of four carpenters who were given a theme a few hours before the start of the competition.

This year’s theme was “A seat at the table.”

The teams then had five hours to make something beautiful using wood and other recycled material from old buildings.

Organizer Der Lovett, of Lovett Deconstruction, said the event raised money this year to encourage more women to get involved in the building trade.

People set the stage for the Dropbox Derby auction. Dozens of handmade pieces of furniture are auctioned off to support Oregon's Tradeswomen Inc.

But there’s another reason more than 100 carpenters chose to work on Labor Day: “Chefs, fashion designers — everybody gets to compete and show how good they are, except carpenters,” Lovett said.

This is the second year the Dropbox Derby has taken place — and it’s twice as big this time around.

The pieces created Monday are scheduled to be auctioned off and given away to charities. Six pieces will go to OMSI for public enjoyment.
