I removed the seperations from the outside sections of one of the manifolds today. I had to do it all with the mill because we are still without an air compressor. It took forever. I really need to be doing a combination of cutting out pieces with an abrassive wheel and milling out the rest. The air compressor I want is on back order and apparantly is going to remain on back order for a few more weeks so I guess I'll buy one in town that I can settle for.
