I have some hollow core doors that are 80" in height that I need
to cut
down to 78 3/4". They seem to have a 2" frame on the top and bottom. I
am going to install by-pass roller hardware on the top so I think I
should only remove wood from the bottom. Do you think I will degrade
the integrity of the door if that much is removed from one end.

I apologize for the multiple posts. I posted the question and never saw
it appear in the newsgroup; so I changed something in my newsreader
configuration and tried again. I tried again... Then, the third try
worked. Then, the first two appeared hours later. Confusing. I though
I had something setup wrong. Sorry.

It happens Michael, don't worry about it (grin).

On the door, we have similar. You may be happier just getting another door
and the reason is if yours are like ours, the thin veneer wood covering will
splinter if you try to cut it down.

That said, if you want to try it, by all means work from the direction you
list and be prepared to have to add a new thin wood at the bottom up inside,
basically 'moving up' the wood that is there now or replacing with a new
piece. That piece now is probably only 1 inch or so thick even if it seems
more before you open the door up. So you cant just take it out and leave
the bottom 'floppy' or it will get damaged fast.
