Buying Guide
Key purchase considerations for a mortise and tenon jig:
- Table saw compatibility: Check groove size (most standard jigs use 3/4″ x 3/8″ grooves or 19.05 mm T-slots) and whether the jig fits your saw’s throat and fence configuration.
- Clamping and hold-down: Look for quick-clamp features, solid back stops, and adjustable pallets to ensure workpieces stay secure during cuts.
- Adjustability: Consider range of motion for the back and rear pallets (0–45 degrees typically) to enable varied joinery angles and joints.
- Mortise and tenon options: Verify supported mortise lengths, tenon widths (common options include 1/4″, 3/8″, and 1/2″), and compatibility with stock thicknesses you commonly use.
- Build quality and materials: Metal constructions offer durability and repeatability, while plastics may reduce weight and cost but could wear over time.
- Ease of setup: Look for clear alignment references, scale marks, and included guides or bits to shorten setup time for repetitive jobs.
- Shop context: For hobbyists, lighter, easier-to-use jigs may be ideal; for production or cabinet work, heavier, more precise jigs with repeatable positioning are beneficial.
- Safety considerations: Ensure the jig design minimizes cut risk, supports proper clamping, and keeps hands away from blades during operation.
