Rolland,
Very nice project and coming along nicely. I am very impressed that you took on the job of making your own mono block, it looks like you did a very nice job of shaping and working it down. What tools did you use while shaping it? I see that you have an air grinder in the backgound, did you use that for most of the shaping? Don't give up, you are well past the place that many would have quit. Sometimes the most difficult part is keeping up your enthusiasm for the job. Bob
