Festool + Titebond window fix
Experienced woodworkers are recommending a Festool Domino jointer paired with Titebond III glue for repairing mullions, muntins and opening‑stays on windows. [](https://x.com/i/status/2031962408118280441) The combo is being shared as a reliable way to preserve and restore original window frames. [](https://x.com/i/status/2031962408118280441)
A Festool Owners Group thread documents a shop-made jig workflow that used two alignment jigs and "8×50" Domino tenons at each corner to rebuild narrow mullions and muntins with repeatable accuracy. festoolownersgroup.com Titebond III is specified by the manufacturer as a Type I, waterproof adhesive and the product literature lists an open assembly time of about 8–10 minutes and a total assembly time of roughly 20–25 minutes at 70°F/50% RH. titebond.com Some restorers compare adhesives in practice: one Festool forum poster reported gluing half a project with Titebond III and half with two‑part epoxy, and added stainless steel screws through tenons for extra security after gluing. festoolownersgroup.com Domino tenons and cutters are widely available in sizes used for sash work (examples include 5×19×30mm and 8×22×50mm packs), and community modding—like 3D‑printed glue‑nozzles sized for 16oz Titebond bottles—has circulated to speed glue application for multiple small Domino joints. amazon.com
