Re: Need one-inch-wide pulley to run 6-v, postive ground alternator

I make a lot of parts for rare cars so I have some idea as to cost. Machining a pulley would cost hundreds of dollars and require a design for the machinist. I suggest you take the pulley you have that fits the alternator shaft and use that hub. Then find a 1" wide pulley of the correct diameter and give them both to a skilled fabricator. They can cut both pulleys apart and weld the 1" wide rim to the hub to give you what you need. Make sure the fabricator is skilled at welding and machining so you do not get something warped. The welded pulley needs to be held in a concentric position for initial tack welding. All this would cost more than a correct pulley but way cheaper than machining from a solid bar.
