I don't care about weight advantages, but if I did, I would pay a bit more for factory drillium. Crappy home made drillium ruins the part.

Being a retired machine shop owner ( CNC and conventional equipment ) I find this thread interesting . As far as a price for sure it would vary even if you could find a shop to do it . One thing you might not be considering is a fixture to hold the ring , to make that is time to make a program these days is no big deal but again time and then of course the actual machining remember you have to chamfer both sides more time . So lets just say three hours times the shop rate . When I closed my shop in 2010 my rate was $ 60 . a hour . You say you have access to a shop , so do it your self and if you have not much experience I'm sure your friend will help you get started . I have been thinking about a little drillium my self . I have been thinking about a jig holding fixture . First get a aluminum plate 1/4 thick should be ok and about the size of your chain ring . In the upper edge drill and press in two pins this will be your locating stop . The distance between the to pins will be the distance between two teeth on your ring . Now bolt this plate to a mill table put in the ring and locate where you want your first hole, lock the table.
You should be able to just hold the ring by hand but a clamp would be better drill a hole , remove ring and debur the backside repeat in till done . Next chamfer , this must be done precision no fair different diameter chamfers and no chatter marks . Sounds like some work .

Look very closely before insulting someone's work.

I tend to think factory drillium parts or chainrings are worth more, obviously considered a higher performance part. That said, some of the older vintage drillium 'factory' parts are not so finely done. Zeus comes to mind. You can even see flaws in chainrings depicted in the brochure.

He was more at least the work I saw and talking to him, about alternate materials and conceptions of the design of components. Besides the ti lugged framed track bike he paraded around the infield of the 1974 National Championships. The magnesium seat post was clunky, the drive line on the LH side smart for a steeply banked track but his was a pursuit bike..? hubs with radial spoking and the spokes double ended threaded, screwed into the hub, Mavic would do this decades later, the internal and external threaded spoke nipples to secure the spoke in compression as well as tension… I could go on, lots of creative details.

Fixtures and set up sometimes take longer than the machining it's self . You guys are inspiring me I think I will make that drilium fixture that I was talking about in my first post , although the shop is gone (good riddance) I do have my little "closet" shop with a nifty little drillium press and a vintage Craftsman lathe .

I do my own drillium with a benchtop Craftsman drill press and a small pin vise with a chamfer tool. I layout my pattern in AutoCad and print it at 1:1 ratio. I tape it to the chainring and mark each location with a single "ping" of a center punch. I then drill and chamfer. I have very good results.

That guy is consistently wrong about nearly everything, yet speaks with total confident smugness.

And after that, take a look at his chain ring page. Amazing work.

yeah, he fits right in, here!As to the question, what would I pay for [blah blah yada yada] drillium, consider that the average hobbyist painter can get a $10 canvas and spend several hours pouring $10 of paint on it, and end up with a painting that no one, even a relative, would pay $5 for at an estate sale.
I'm all for art projects. I'm all for almost all the reasons people take on crazy art projects. But money, no, that is not a good reason. If you want to drill, baby, then drill, baby, drill. If you have NR chainrings to sell, I'll take the undrilled one, please!

We picked up a few of them last year...hopefully they find new hobbies to be overnight experts about.

Back in the day (1970's) a couple of my friends that worked at other bike shops in my town (Cleveland) drilled their bikes. I just never got in to it. The shop I worked in during high school had the equipment for drilling but I never took the plunge. Never really liked the look and didn't think it saved enough weight to make it worth the effort, time, etc.
My hat goes off to folks that do it though. It's a big commitment and does take a lot of skill to do it right. I will admit that a fully-drilled classic bike does look pretty cool though.

A lot of holes can be cool looking. But I like a more subtle approach. Less is more.
And I like millium more than Drillium.
By the way, who came up with that name? It's silly.
