internal door - Chippie question

 Hopefully there are some chippies here.

 

I have a couple on internal doors that I need to trim ~25mm from the height.  They are the stock standard Hume hollow doors.  Do you know what the thickness of the rail is.  I am hoping to plane 12mm from the top and 12mm from the bottom (if I cannot domm 25 from one end).  Do I have to be concened about the corners - where they joing the stiles?.  If that is the case planing 12mm from each side might be the go.

 

Thanks

Take 12 off top and bottom

Take 12 off top and bottom and you will be fine if  they are new doors? I’m assuming your taking it off due to new flooring? If they are original doors by taking it top and bottom  it will throw out your hinge positions,

Thanks heaps Chook.  I think that is the best approach.

Measure 3 times, cut once.

 

 

Tim.....yes that was my first choice. But only the overall dimensions were stated.

And don’t plane right through

And don’t plane right through from one side of door or you will chip out the other side, come from both sides

 25mm is the rail

 25mm is the rail thickness.Hume will only say to take 3mm off each side.Having said that plenty of doors that have been hung with 10mm taking off a side.

Have even seen the rail completly cut off and expanding foam put in.Not something i would do 

Also could remove the rail,cut door and reinstall/glue the rail

Could of got a 2020mm door as opposed to a 2040mm which is a standard door size for lift off hinges in wet areas.

If you do trim the 12mm off each side dont use a good plane blade as you will be guranteed to hit a staple.Circular saw with a straight edge other option.
