Straighten Oak plank
« on: December 23, 2016, 01:50 PM »
I’m making mirror frame in oak. Long parts (stiles?) are 165 cm (5’4’), plank is bit bowed, say 3 mm (1/8 inch) in that length. There is not enough material to plane it straight.

Is there any chance to straighten that plank?
- maybe force it in other direction for few weeks and hope
- route a long recess and fill it with another part of that same plank (like inlay, but thick one)
- steam it and somehow put it straight
- ..

For me oak is a relatively costly option, hence the question.

Do a Google search for 'relief cuts' and you will see what may help in this case. Also on YouTube 'hffcom' has a few video's where he shows this technique.

You could try ripping it in half, flipping one piece around and gluing them together so the curves cancel each other out.

I have been in flu for couple of weeks, so haven't done anything..

That Frankenstain method (relief cut) is not for me. Knowing that backside of mirror is ruined ..  :o

Maybe couple of new planks are not that expensive, compared  the extra work with sawing, glueing and planing and trying to get pieces straight.
