Hi
I recently moved into a 150 year old house. All the sash windows are original. However some of the windows have very bad rot and are actually badly bent.
I have removed all the bad windows, removed all the glass & have treated them for rot. However i am not sure how to rectify the problem of bent wood. I guess i could clamp them straight, but it would probably take many months before they would stay straight when i remove the clamps. Is steaming the wood a way of straighting them?
Anybody got any ideas? The wood is Pitch Pine.
Thanks

Any reason you don't want to make replacement pieces for the bent sections?

Hi colingsn,
Sounds just like the problem that I had in our 1865 building.
I used Abatron liquid wood to consolidate the rot and soft spots. The bent sash window I straightened by planing the high spots down an rebuilding up the low spots with abatron WoodEpox. Where the M&T joints meet I used a lot of liquid wood, so it's practically all epoxy there.
The results are strong the WoodEpox is light, but I believe that I will have to replace the sash as it's still not 100% flat and lets in much more draft that the others.
I would build a fresh one as it's probably a similar amount of work all said.
Hope this is helpful,
Best regards,
Paul
FYI. This guy makes bronze cushion weatherstripping.

They were very pleasant to deal with and not that expensive. I used the cushion V type along the inside of the casing where the sashes ride. That and a little paste wax every once in a while and your windows will slide up and down very easily.

Col,If you don't mind a little cosmetic touching up, I suggest laying the sash sections (or if taken apart )the bent individual rails..on a flat surface.
With the cupped side down(and the crowned side up), determine the high spots of the bend. Mark the OPPOSITE side directly below the high spots' Then (using a thin crosscut saw,) cut through the rail but ONLY about 3/4 to 7/8 ths of the way through the rail.toward the crown (High side )
By clamping the rail,(saw cuts up) to a table or plank, the wood will flatten out and the saw kerfs will spread open somewhat.
Make some thin tapered wedges from hard wood and apply glue to the kerf and wedge,then gently drive in the wedge with a hammer.
Check with a straight edge to ascertain flatness and adjust to fine tune,
After glue dries, cut off extra wood and sand smooth.
I use wood wedges made for axe handles (ACE HDWE)
Good luck Steinmetz
Hi
Thank you for answering my problem on the 150 year bent window. I think your suggestion is brilliant. I dont know why i did not think of it myself. The window is so bad that i will have to do a lot of cosmetic work anyway. I know that most people would throw the window away and buy or make a new one. If i had the money i think i would have got a new one. Anyway this project has turned into a real labour of love. I will be attempting your suggestion in about a weeks time and i will let you know how i get on.
Many Thanks Again

Colings, I've straightened out doors and sash many many times. I know you'll succeed with your project.I wish you luck I noticed that you reside in Dublin. I visited there back in 1951 and had a great time there I stayed at a small bed and breakfast very close to Trinity.I still recall (It was winter) and the house maid brought in and placed what I'd call charcoal foot warmers beneath the blanket at the foot of the bed.Being in uniform, quite a few Dubliners addressed me as "Yank" I met the lord Mayor and toured Guinness brewery
I arrived at a station on the Great Northern and two nice young boys offered to carry my bags.I thanked them, but,declined their offer. The next words they spoke remains in my memory ever since. "Ha ya gut anie goom av ya?" they said. Of course, they got a whole pack of chewing gum for their fine greeting' Both of my grandsons and my daughter have toured Ireland as well.

Hi Colingsn,I think that you have your solution. I wish i'd thought of that when I was doing my windows.You say it's a real labour of love. You're not kidding. It took me ages to strip 140 years of paint on ours and get it all consolidated. Still, after removing the glass on 24 panes and reglazing you've got another skill under your belt and Im sure that the results will be well worth the work.I'll see if I can dig out any before and after pictures from my 'labour of love'I'm not sure how you intend to finish. I painted, but the casings on ours are softwood (Hemlock I think) and the resin from the knots bleeds through regular oil based primer. I switched to shellac based primer midway though the project and don't see any bleed through with it.Best regards
Paul
