if your friend is any good at what he does he can measure the mini and its components himself and know with 100% certainty how much material he should be removing
also I dont want to rain on a parade but making the body out of stainless would not really accomplish anything other than make the marker more durable and heavier
aluminum is plenty durable for paintball though so I would just stick with the stock body
the last thing you would want is to make the walls too thin or even worse actually breech any sort of pressurized chamber as that would essentially scrap your body, unless you feel like tig welding a plug in and re-annoing it, even then the colors always look mismatched where the weld is
I know it may seem like everyone here is critisizing you but dont take it that way. We are mostly trying to save you the headache of doing something you may regret
one more thing
I went to school for 2 years to get my machinist cert. and we didnt touch CNC until the 2nd year. I am finishing my third year now to wrap up my associates in MET (last two classes actually)
I will say unless your friend is on that cnc machine daily for several months and has access to what ammounts to a well equipped job shop with a vast array of tools and fixturing, he most likely will not be giving you a fancy mill job.
The first semester he even see's a cnc machine will likely be spent writing his initials out in simple code on a 5x3 plate and doing other mundane manual coding just to familiarize himself with program generation.
If you do end up with some fancy crazy milled one off axe though definitely post that **** up.
and believe me I program and run cnc machines daily but I am still so far from the expert I really want to be
