Straightened a 45 year old hardwood window board using a home made steamer box (wall paper stripper as steam supply) and clamps as part of a room renovation.
I was going to fit all new window boards but when I removed years of paint and varnish and found the existing ones are all hardwood I decided to keep them as they're better than softwood and a big cost saving on new hardwood.
Most are flat but a couple have been fitted on out of line wedges so have got some bowing after all these years forced out of shape and dry clamping didn't do the trick after several days. I could have forced them flat with fittings but an hour steaming and a couple of days clamped and they're surprisingly flat even now fully dry!
