Complete Gate and Railing Construction: From Bar to Barrier
Gates and railings secure property and define boundaries. This campaign covers gate design, forging techniques, joinery, and installation.

Chapter 2: Gate Frame Construction
Basic gate frame: 1) Forge rectangular frame from 1 inch square bar. 2) Frame dimensions: gate width x gate height. 3) Join corners with forge-welded mortise-and-tenon or riveted lap joints. 4) Add diagonal brace (prevents racking/sagging). 5) Diagonal runs from bottom hinge corner to top latch corner. 6) Add vertical pickets or horizontal bars (infill). 7) Space pickets 4-6 inches apart (prevents livestock passage). 8) Forge weld or rivet pickets to frame. 9) Add hinge hardware (pintle and strap, or barrel hinge). 10) Add latch (thumb latch, slide bolt, or ring latch).

Railing assembly: 1) Set newel posts (anchor to floor with base plates and bolts). 2) Measure and cut top and bottom rails to fit between posts. 3) Mark picket locations on rails (4 inch maximum spacing). 4) Punch or drill holes in rails for picket ends. 5) Insert pickets through rail holes. 6) Secure pickets (weld, rivet, or set screw). 7) Attach rails to newel posts (weld, bolt, or tenon). 8) Add decorative elements (scrolls, leaves, finials).

Reference Card
The diagonal brace prevents sagging (a gate without a diagonal brace will rack and sag under its own weight; the brace must run from the bottom hinge corner to the top latch corner). 2. Hinge placement determines gate life (hinges must be strong enough for the gate weight and mounted to solid posts; weak hinges or rotting posts cause gate failure). 3. Four-inch maximum picket spacing (building codes require that a 4-inch sphere cannot pass between pickets; this prevents children from getting stuck). 4. Forge welding makes the strongest joints (a properly forge-welded joint is as strong as the parent metal; rivets and collars are alternatives when forge welding is not practical). 5. Scrolls add elegance with simple technique (heating bar and bending around a jig creates flowing scrolls; they are the most common decorative element in ironwork). 6. The collar hides the joint (a decorative collar, which is a band of thin metal wrapped around a joint, conceals rivets or welds and adds visual interest). 7. Paint is the best outdoor protection (bare iron rusts quickly outdoors; oil-based primer followed by a topcoat provides years of protection at low cost). 8. A well-made gate announces the property (the gate is the first thing visitors see; quality ironwork communicates craftsmanship, permanence, and pride).
