Exploring the Versatility of Slot Mortisers

The video “Why I don’t own a Domino Joiner (use a $120 Slot Mortiser instead)” is by Norman Pirollo of WoodSkills. In this informative presentation, Norman shares his insights on using slot mortisers as a cost-effective alternative to the expensive Domino joiner.

Understanding Slot Mortisers

In woodworking, achieving precise joinery can often require specialized tools. Norman’s approach showcases the use of a Jessem Mortise Mill, which he has adapted for horizontal use. This setup allows for the creation of loose tenon joinery, making it an excellent option for various woodworking projects.

Setup and Functionality

Norman discusses the two setups he has utilized. The first is an earlier version where he mounted the Jessem Mortise Mill horizontally, using the surface of a table for support. The second, a refurbished vintage dedicated horizontal mortiser, enhances the efficiency and accuracy of creating slots.

Micro-Adjust System

A key feature of Norman’s setup is the micro-adjust system he developed. This system allows for fine-tuning the position of the mortise, making it easier to achieve the desired depth and offset. By using a hand crank, the adjustments can be made smoothly, significantly improving the user experience.

Creating Mortises

When it comes to creating mortises, Norman emphasizes the importance of securely clamping the boards. He uses a deep throat clamp to ensure stability while drilling. The precision of the setup allows for accurate placements, which is crucial for creating strong joints.

Conclusion

Norman’s exploration of slot mortisers provides valuable insights for woodworkers seeking efficient and cost-effective alternatives to traditional joinery methods. The adaptations he has made to the Jessem Mortise Mill not only enhance its functionality but also highlight the potential of using more accessible tools in woodworking projects.
