Because engineers have a goal, to make a bike part as strong as possible using the least amount of material necessary, and we go and mess up the integrity with more holes, for grams and coolness factor.
I'll admit it, I think it looks cool.

I'm assuming that Jon Williams' work is mentioned in the other thread, but if you haven't seen his flickr pages and all of his goodies, please check it out!
An example is the crankset on Dale Brown's Baylis that he displayed at the 2018 Classic Rendezvous gathering.

Duo The belts are link belts . Very handy for determining the belt diameter , but not very grippy . I need to change over to a regular fan belt .

Sure, I've got pre-drilled or lightened stuff, but no one wants to see that. I'm also pretty sure nobody wants to see me take my little hand drill and massacre some parts, so maybe I can just share another bit of interesting work by one of our dear departed craftsmen?
I'm thinking of the esteemed Roland Della Santa. This is the guy who built frames for Greg LeMond (IIRC) and no doubt other great riders. All I know is that he had some great and interesting frames on display at the two NAHBS that I've attended. Here's a shot of him at the 2015 NAHBS in Louisville, KY... (he's on the left, facing us)
The frame that he is leaning on was there to display his novel "ossobuco" chainstay treatment. I never did hear whether this was a serious modification or just a showcase for some difficult work. I seem to recall stories about Pino Morroni using small rods or tubes in a similar fashion to brace or reinforce lightweight frame tubes.
Obviously, the chainstays had to be drilled, but then they also had to have tubes brazed into the holes afterwards. For some reason, it's the idea of having to paint the insides of those little tubes that strikes me as being the hardest part of the operation.
In any case, this seems to be a case of taking an idea and carrying it to the extreme, and doing it extremely well! Thank you Roland!

If I was in Roland's shoes, I would have kept saying to myself, "I hope this doesn't whistle when I'm done!"

So nice! I've seen a lot of those images from previous posts, but it was fun to scroll through the full album and revisit your work. Really nice close-up photography, too. With those brake calipers that got a lot of drillium treatment, I know it's hard to quantify, but how much more flex did you feel afterward?
I never ended up using either pair of drilled calipers, nor did either of the people who commissioned them AFAIK. They were more an exercise in aesthetics than a sincere attempt to lighten up a working pair.

I love the look of the Ossobuco and Masi Prestige treatment, but I do wonder if it was more show than effect. It clearly looks like more material is added than removed, so the purpose must be to increase stiffness, right? Surely there are easier ways to accomplish that end. I would think there has to be an wind resistance penalty, too.
In a similar vein, I own a Hetchins with curly stays. I don't detect any more flex from the curly stays, but they do look cool and attract attention. To give Hetchins credit, they don't hide the fact that many of their features are just there to look cool.
Practically, I think those tubes are too short to resonate at a frequency that humans can hear.

.. I feel obliged to offer a shot of my Hetchins now....

This early 600 crankset came attached to a 1980 Peugeot PXN10 I recently purchased.

At the 2018 Classic Rendezvous gathering, I noticed this drilled chainring in the swap meet area....
The pattern of different size holes almost makes it look like lace! There wasn't any obvious indication of who did this, but I'm certainly impressed!

The Stronglight crank is cool- it looks like there's 4 chainrings! The red RINO rings are stripped and on the Avocet crank.

ca 1974 Masi GC. In the original thread that was linked in this one, I mentioned I had plans for the drillium I shared. The rings are by Drillium Dude.
