If you didn't know the right way, you would be wise to watch someone and learn how,
not experiment, and botch the job. I've hung some hand carved doors that cost $1600 each
so it is with many things in life including quitting smoking. Certain things work, others don't.
How many doors are you willing to ruin to do it your way?
BEWARE: As A Door Is One Of The Most Skilled Things A Carpenter Does, So, This May Run Long.
