I've never made a reamer but have researched it. When making say a six flute reamer I have read one thing that can trip you up is cutting the flutes equidistant around the circumference of the reamer. Apparently doing this can easily lead to chatter when cutting a chamber. This can be avoided by offsetting some of the flutes a few degrees.
Speerchucker30x378 (Rod Henrickson) talked about this on Practical Machinist. He had a lot of good posts over there until he got tired of arguing with a couple of knuckleheads that thought they knew more than a gunsmith with 40+ years of experience. He has a very straightforward method of chambering using the steady rest and a lubricant flushing system. I reviewed it with my machinist friend who was a tool and die maker for IBM in Colorado for 30 years and he agreed with the method. Good enough for me and I'll try it one of these days. I'll be using a purchased/rental reamer though!
