Clamp Time

Depends on the torque of the piece or that the piece has on it, but I’d say one hour is minimum to get things to stay put with TBII.

If you didn’t joint well and are using the clamps to help tighten the joint then leave them till tomorrow, if the clamps are just to align the wood then 1hr.

Don’t know what you’re gluing , but my cutting boards range from 5/8” to 1.5” thick and an hour is usually sufficient for them. Haven’t had a joint failure to date : )

-- When did quiet and quite become the same word ? I'm guessing about the same time as your and you're did.

It depends also fo me if it a tray divider or box mitre joints. Two hours will probably hold. I try to leave bigger joints 24 hours. Just me.

I guess it’s going to depend on how warm it is in your shop Bondo and what your gluing. large panels I like to leave in overnight but things without a lot of stress on them 2-3 hrs in 65 degrees.

2 hrs should be fine for most joints, given a decent temp, long grain to long grain joint. You may not want to run the joint through a planer or jointer for a while longer.

This past week I glued up over 1200 lf, 6 in wide poplar for base moulding, 30 min rotation, took close to 10 hrs to get it all glued up 30 min through the moulder. no glue failures….

I’m gluing some smaller panels 12”x32”, 2 boards in each panel, species is poplar. Shop temp 60°, but will drop to 50° overnight.

I was told to leave wood in the clamp for 4 hours. Now days I keep reading that people are using less time in the clamps. I still try for the 4 hours and longer if it is cold.
