Is a leading edge always necessary (when hanging a door) (Ed.)

[Seanevil]

I put on hinge side also because sometimes lining may be twisted or paint build up causing hinge bound. In fact I cut most doors with plunge saw on rail so set up slight tilt of 1.5 degrees on saw. This gives correct leading edge for doors as narrow as 686mm( any narrower may need a bit more).
When changing existing door sometimes necessary to cut all 4 edge of door to fit old linings and I don't reset the plunge saw as you cannot se the slight bevel anyway. (Removed)

Seanevil,
Thanks for your post - although as you probably know its an old thread but its still a good informative thread.
Glad you mention dealing with all four edges - sometimes its a toss up whether to re-do the lining or work on the door.
In older, Heritage/Conservation situations we always had to make the door fit - we couldn't touch the surrounds - with the Conservation officer stood watching.
I'd be interested in hearing more about your uses of the plunge saw & rail?
