Precision 'Glue-Ready' S4S Lumber or On-Demand Milling Service for Woodworkers.

The user and commenters are frustrated that standard S4S lumber often doesn't meet 'glue-ready' standards, requiring a lot of extra jointing. This points to a clear need in the market for lumber that truly meets high precision standards for flatness and squareness, ready for immediate use.

Opportunities include:

  1. Product Opportunity: A premium S4S lumber line specifically marketed and guaranteed to be 'glue-ready.' This would involve stricter quality control and potentially different milling processes to ensure flatness and squareness within tight tolerances (e.g., +/- 0.005 inches over a certain length).

    • Expected Benefit: It would appeal to woodworkers who value convenience and precision and are willing to pay more for material that saves them significant prep time and reduces the need for expensive jointing equipment. This is especially valuable for hobbyists or those with limited workshop space and tools.
  2. Service Opportunity: A specialized "Precision Milling Service" for woodworkers. Customers could buy rough or S2S lumber and have it professionally jointed and planed to their exact specifications, ensuring it's perfectly flat, square, and ready for glue-up. This service could be offered by existing lumberyards or as a standalone service.

    • Expected Benefit: It caters to woodworkers who may not have the large, expensive machinery (like jointers and planers) or the time and skill to achieve perfect results. It offers a cost-effective way to get precision-milled lumber without investing in equipment. It also helps reduce material waste, as the service provider would be an expert in maximizing yield.

What’s the point of S4S boards if I still have to joint them?

I have NEVER purchased S4 boards that were even close to ready for glue up. I get that there would be minor variations, but the “jointed” edges are a joke. They always require a ton of furthe

Agreed, and this why s2s or rough sawn is better depending on your tools and how much time you want to put into a project
