Hello, Crazy Bob!
First, let’s consider cast irons. Most cast irons can only be bent 1-2* and then only with considerable skill, as you’ve already learned. Others cannot be bent at all! Only a few can be bent more.
Here is a link for information on some irons where bending is not recommended – http://www.golfworks.com/images/art/Iron%20Models%20Not%20Rec.pdf.
If your irons are not on that list, they may be bendable. Still, it is very wise to check before having them done.
As far as fairway woods, most of them are not bendable. Adjustable drivers, on the other hand, can be adjusted by changing the settings on the adaptor, although those settings are limited. Most have an upright position as well as open, closed and neutral face angle positions.
Before I make lie (or loft) angle changes for my golfers, I have them hit balls off a lie angle board to determine what, if any, changes need to be made. One gentleman wanted me to bend his wedges more upright. I tested him and he needed them adjusted more upright 2 degrees, but his wedges were unbendable. (He ended up having me custom fit him for the Maltby M-Series wedges, which I did adjust upright. He loves them!)
Whomever you choose to test you for proper lie angle and to bend your clubs accordingly, be sure they have been trained and certified. I hope this long answer is of some help to you! Michael
