2026-01-19 – Weekly Woodworking News : Mortise vs. Tenon Troubles

Last week in our woodworking community, members shared insights into the nuanced challenges of joinery, from mortise and tenon fits to identifying mysterious wood grains. There was a lively exchange on troubleshooting common woodworking issues, with experienced woodworkers offering guidance to those facing persistent problems. We also enjoyed a lighter moment with members sharing humorous anecdotes from the woodshop, reminding everyone that even the best plans sometimes go awry.

Looking forward to seeing more of your projects and discussions. Keep the sawdust flying and the ideas flowing.

I lightly hollow the tenon cheeks with two passes of a router plane so it bears at the edges and avoids hydraulic lock — if I hear a soft ‘pfft’ on dry fit instead of a squeak, it’s right. In humid weeks I leave a hair more clearance; anyone else do this?

Had the same “squeak” fights last week — tiny vent helps more than thinning the tenon. I pop a 1/16" hole in the mortise bottom or score a quick glue groove down the tenon with a marking gauge; two-minute fix, no more hydraulic lock. @dannyK92’s edge-bearing trick is solid, but if the joint’s visible, skip the through-hole and stick to the groove.

I scribe a shallow “glue trench” around the tenon shoulders with a marking gauge, plus a tiny chamfer on the tenon end; it gives squeeze-out a home and lets the shoulders close cleanly without fighting pressure. It won’t rescue an over-fat tenon, but paired with liquid hide glue it’s been dead simple for me on tight fits.
