What you get: joint sheet
Worked out by this tool from its default inputs. Its role plan lets you run your own numbers, print the sheet and save it.
24 joints (butt joint) in 3/4 in stock: 4.0 hours, $180.00 labor; suits interior, dry work
- What it is
- Two square ends or edges meet with no interlock; held by nails, screws or plates.
- Best used for
- Rough framing, quick boxes, hidden work, wall plates to studs.
- Strength
- Weak alone (end grain glues poorly); relies entirely on fasteners or metal connectors.
- Tools needed
- Saw, square, nailer or drill/driver; framing connectors.
- Common mistakes
- Gluing end grain and expecting strength; fasteners too close to the end splitting the board.

The plain-words read of this example
For 24 joints (butt joint) in 3/4 in stock, the key cut is cut: Square ends; check with a square before fastening. Where it goes (interior, dry): suits this work; strength: weak alone. Use interior wood glue (pva); end grain glues poorly, so fasteners carry any end-grain joint. The batch is about 4.0 hours of labor, $180.00 at $45.00 an hour. Make a test joint before cutting the batch.
