I dont mind at all!
First thing would be for me to forward my work log:

That will show you a lot of the "how"
Main thing to remember when you are using a dremel or a jigsaw is to be patient. My rule whil I was cutting was "I can still take off, but I cant put back on."
I burned through a ton of reinforced cutting disks, and used some of the smaller disks that I'd worn down, to work in the smaller areas.
When I wanted a good, hard point, I tried to use lighter, more narrow cutting wheels. Worked to some extent.
Also, get a good set of metal files and watch those edges! I cant count the number of times I jabbed a sharp flame tip into (and in one case through) my finger.
My next bit of precision equipment will be a drill press. Hopefully in a few weeks after I clear a spot in the garage for it.
Get a good dremel (not battery powered), and watch the sales at Lowes or Home Depot for the multi bit rotary tool set sales. You can get some killer deals when you buy those kits of bits!
Hope this helps!
