I know it is not an interesting question for many of yours but the information I found was messy and sometimes one against the other.
What about the curve the reed needs? Have I to bend the free end or the base of the reed?
What is theproper height between the free end of the reed and the slot?
Any visual help of this aspects?
Thank you boys in advance.

Im not an expert customizer..I like working on my harps and i can share what has given me the best results..
after flat sanding the comb , the draw reed plate and embossing the harp.
I do the gapping...I keep the reeds as straight as i can , taking out whatever curve there is.
I used a method which I read somewhere by Dick Sjoeberg and tht has worked very well for me ..Ill paste it below
"Close the gap by working at the the last 1/3 of the reed near the rivet until the reed chokes. From there open it gently up again by working at the same 1/3 near the rivet, but this time from the opposite side. This gives you full control over the opening and closing action of the reed. When the reed starts to sounds at the "whispering pressure", then its time to increase the blow/draw pressure to find out if it chokes with higher pressure. If it does, open the reed slightly until it just starts to sound at the new pressure. Repeat the process until you can apply normal pressure at the reed."

I appreciate your answer logan.
I received an email from Mr. Sjoeberg yesterday, who was so kind to answer my question, advising me to do the same you are saying.
I think the "secret" is to work near the rivet and not in the free end in order to keep the reed straight.
Thanks again.

The reed needs to be straight as it goes through the slot. That means that it will have a curve in it at rest.
The "secret" is to practice. Here is a good book to find out how to do it:
“Turbocharge Your Harmonica Volume 1- Straighten Up and Tune Right” - Richard Sleigh
