If you do it yourself, you need a saw to cut metal, you need glue to fix the shaft and head together. You'll need tape and petrol to put the grip on. You'll need some cleaning materials as well. Gloves (like surgical gloves) are also useful. You need lead to weight it correctly, hosel plugs and a ram rod.
The type of shaft you use depends on the head you select. Some have different bores, some have different recommended shafts. Some heads require specific shafts and tips. You also have to careful that the butt width of the shaft will fit the grip you select.
I suggest you select the components and then send the "shop" an e-mail for them to check your order that the components are compatible.

www.dynacraftgolf.com. I use their
irons and I sometimes carry thier wedges and I custom fit their equipment at the Studio. If you buy your components from them and send them an e-mail, they will make sure everything is correct without a problem.
