Hey Texas,

I have always just trashed brass once it has been scarred. But I had a brainstorm just now while pondering your problem. Well, brainstorm might be a bit strong; more like a synaptic squall. ;-)

I don't know if this will work or not but is inexpensive. Chuck the brass in the vise (just snug; don't squeeze it). Make a flare on a piece of line about a foot long. Wrap the other end of the line with duct tape to make a handle. Put some lapping compound on the seat of the brass. Use the flared line just like you would a lapping tool to lap the seat. Clean it off and see if you made any headway on the scarring. If you are successful go ahead and clean up all the ports in the same manner. Be sure to clean ALL the lapping compound out of the brass block. Rinse with brake fluid before installing it.

Just in case; you use a lapping tool by holding it between the flattened palms of your hands and making a motion like a Boy Scout trying to create fire with a stick; back-and-forth rapidly.

Let us know if this works. I have never heard of anyone doing this but I think our grandfathers would have tried it before walking to the parts store to get more brass. You do what you have to do.

BTW, on that front block -- if you count the switch port, that is a five way junction block.
