Lets see your drillium!! Post those holes.

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.

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!

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 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.

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

Thank you

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.

In the same way that most drillium parts were an attempt to crudely modify a production part that could have more effectively optimized by other methods, I think the "drilled" chainstays are not likely to be a serious solution to a problem. My guess is that the Ossobuco is simply a cool way to show off Roland's skills and to get people to stop at the booth. I'd say that Masi was also just looking for publicity with their "slotted" chainstays. If they (including Roland) were looking for lightness, they could have used a lighter gauge tube. If they were looking for stiffness, they could have used a heavier gauge tube or ovalized the tube.

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.

Hey, he might have loved it if they whistled, especially if it sounded good!
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....

My exact thought. Quick eyeball math led me to think the frame is actually slightly heavier with this treatment.

But damn, that looks awesome.

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!
