Retired journeyman machinist / QA Manager here. (i know it's long and detailed SORRY)
nice dream, machine my own guns. looking at the price sheets you had attached those are very affordable.
my guess would be if those parts were not available, and you just happen to have a detailed enough blue print for someone to make you one it would cost 3x's or more those amounts. if a print needed to be created reverse engineering from the old part add another 2 or 3 x's. those would no doubt be hand machined.
to get into the cnc world ....
you need a cnc mill 50K - tooling 10K - a place to put it all ? - measuring / inspection equipment 10K
now the time consuming stuff comes in and you need more equipment.
now you need a good blue print or sketch or old part
then that has to be drawn in some type of auto cad computer (more $$ computer / software)
that spits out a basic G-code of the tool path to cut the part. (tool path only)
below is a sample g-code path to mill a round pocket using a circular path ( sorry its long, i put at end) that's just one feature of the part you need something like that for each pocket - ear - rib-etc
then depending on how much $$ equipment you have the g-code can be run through a processor to add the M-code (machine code) that code runs the machine changing tools, setting speeds and feeds clamp avoidance (please don't mill the vice) and has all the other information the cnc mill needs to use the tool path the g-code provides then
before a 1st article part came be made someone must create a clamping set up and set tools in tool holders, end mills, drills, taps, reamers etc. then run and debug the process.
granted once this is all done using cnc technology is awesome, unfortunately you really need lots of sales and $$ coming in because it cost a lot to play in the game. and the cost of materials has gone through the roof just in the past 5 years (before i retired (BR)
the other thing i noticed the last 10 or 15 years BR those cnc machines that run full blast all day long and often a 2nd shift and ya hope even a 3ed or part of a 3ed shift get the snot beat out of them, it cost a lot to keep them running the you have to replace them. i have seen brand new cnc mill only last 10 years.
at the moment i'm rebuilding an old 1970's John Deere 300 Industrial backhoe, about half done
but such an awesome idea, something i have always wanted to do, just let me know when ya want to get started i would be happy to have a new project to work on. if you do happen to know someone with the cnc code already worked out and an old working machine just sitting around seems like such a waste not to put it back to work.
this mill would do your job
