I have been writting this for years, but my machine shop guy finally told me Tuesday to bring one of my old water pumps by and he would take it apart, rebuild it and then put it all back together including the pulley. I let him know that I didn't need it, that I was just seeing if he could do it and for what cost. I explained the short supply and that it could turn into a 2 or 3 per month business for him. I told him $50-$70 was as high as he could go for a finished product. He said he would tear into it and see if they can justify the time and actually make money on it. I should here from him in a week or so.
By the way, his company rebuilds oilfield engines and pumps. They know what they are doing and do good work. I will keep updates coming as I find stuff out.
