Skill: Tangs of Wooden Gates
Skill level: 2
Gate Mechanics
Learning Objective
Learn how to carefully shorten the tangs (bottom ends) of wooden gates that are too long, without removing the gate from its hinges. This is a delicate job that requires precision, good judgement, and safe working practices.
1. Overview
Sometimes a wooden gate tang (the lower end of the leaf) sits too low or catches on the ground block. This can result from:
Incorrect initial fitting
Posts sagging over time
Ground movement raising the block
Instead of removing the gate, it is often quicker to trim the tang while the gate remains on its hinges. However, mistakes here are irreversible, so careful marking, measuring, and cutting are critical.
2. Tools & Materials Required
Sharp handsaw (preferred for control)
Square (for accurate marking)
Pencil or marking knife
Tape measure
Wedges or assistant to steady the gate
Reciprocating saw or circular saw (optional, only if confident and space allows)
Work gloves and eye protection
Small torch or inspection mirror (for underside visibility)
Block plane or sanding block (for tidying the cut)
3. Before You Start
Inspect the gate and identify exactly where and how much needs trimming.
Complete all hinge adjustments first — these may alter the clearance needed.
Check for nails, screws, or fixings in the timber before marking the cut.
Decide whether a hand saw (safer, more control) or power saw (faster but riskier) is best for the available space.
Secure the gate so it cannot move during cutting.
4. Procedure (Main Process)
A. Prepare the Gate
Swing the gate to a position where you have maximum access.
Wedge or block it securely so it cannot swing.
Ensure the work area is clear and stable.
B. Mark the Cut
Use a square to mark the cut line all the way around the tang.
Leave at least 5–8 mm clearance above the ground block to avoid future catching.
Leave at least 10mm to catch on the upstand of the ground block
Double-check measurements — measure twice, cut once.
C. Cut the Tang
Use a sharp handsaw for precise control.
If using a power saw: confirm clearance, stabilise the gate, and maintain full visibility.
Cut slowly, checking progress from different angles to stay straight.
Stop frequently to confirm accuracy — easier to correct small deviations early.
D. Finish the Cut
Use a block plane or sanding block to smooth the cut.
Touch up with preservative if the gate is untreated or stained.
5. Best Practices
Remove only the minimum necessary material.
Make several small trims if unsure, testing clearance each time.
Keep cuts square and neat for appearance and longevity.
Always tidy up exposed timber to reduce water absorption.
6. Common Mistakes to Avoid
🚫 Cutting before hinge adjustments are checked
🚫 Removing too much in one go (cannot be replaced)
🚫 Over-reliance on power tools in tight or awkward positions
🚫 Forgetting to check for nails or screws in the cut zone
🚫 Leaving a rough or untreated edge — invites rot and looks poor
7. Safety Information
Always wear eye protection and gloves.
Keep hands and body well away from the saw line.
Never attempt to cut a moving or unsecured gate.
Only use power saws if the workpiece is absolutely stable and space is sufficient.
