Carpenter Toby Swanson gives the collar tie a quick final sanding before assembly.
Working on the bed of the company's flatbed truck, Toby Swanson and Chris Krouse assemble the gable end rafter pair and collar tie. The truck makes a handy flat surface for assembling bents on a rough jobsite, notes company owner Richard Krouse.
The team lifts the completed gable end rafter and collar tie assembly off the truck using the crane.
With the rafter assembly suspended from the crane, Toby applies a quick coat of linseed oil to the timbers. Applying the oil at the last minute keeps the timbers from being soiled or marked by fingerprints during transport and assembly, says Richard Krouse.
Chris and Toby screw temporary bracing onto the gable ends before starting to set purlins.
The crew starts lifting purlins for completing the roof frame. For efficiency, they lift two purlins at a time. The company has placed as many as five purlins with one hoist, says Richard Krause.
With the frame complete, the crew starts to screw rough-sawn barn-board siding onto the walls.

After the show, Toby pounds a purlin back out of its mortise as the crew starts taking down the frame.

With the crane doing the heavy lifting, Chris and Toby re-stack the timbers onto the truck for transport back to the shop.
