Thanks so much and yes you are right different terminology but some of mine probably just plain wrong wherever I am!
So if I say that the sash is the bit the glass sits in we are talking about the sane thing.
There are no glaze bars / muntins. The sash is just the 4 pieces around the glass with no dividers.
In uk most of the off the shelf windows are made with a bigger version of rail and stile type bits I think.
For the project I'm on there is an oak subframe I made which now need the sashes made. For each subframe there are 6 separate sashes. Out of which only 1 is an opening sash. The other 5 are fixed in place.
As I've got to make 60 of these sashes I'm looking for a quick way of making the 50 fixed sashes. So is there a rail and stile type set that will do that?
I recognise the openers may need mortise and tenon but not the fixed ones.
If you know of such a thing that will cope with 58mm thick stock I'd be grateful for a link!
