Th big ring is some of member Otis work (two-wheel-trip on Ebay right?). The small ring unknown. The painting was done by me.

Wow.

Out of curiosity, how much could reasonably be drilled out of a bike such as this--say with Campagnolo SR or NR groupo, saddle, bars, wheelset, and the whole kitchen sink--and still be ridden?

Love the way the conical-shaped drillium helps show off the paint fills.

I might be qualified to answer this

How about this much:













Yep, she's plenty rideable

Nice!

I picked up a bike a year ago that was sold as a Raleigh but its not. No clue as to what it really is. I will be stripping the paint soon and hopefully there is some clues under the repaint.
Has a nicely drilled Record seat post.



The bike is a mystery as to what it is but it is light and it has Campy drops as well as High flange Record hubs. Put a porteur rack on it recently thinking that's what I wanted to do with the bike but its a bit nice to make a truck (and I just came up with a old TREK 420 that work well as a Porteur). I am thinking of going with a Rando style build after spending a bit of time perusing J.P Weigle's Flicker over the last couple weeks. Maybe some 650's.

The Super Maxy cranks are begging to get the rings drilled and the star is fluted.

beautiful work. I have to get that Chorus RD Drillium did for me on a bike.

DD how do you like your Portcantena? unfortunately I have the wrong hanger they are for long dropoutsd

aslong are we are somewhat discussing drillium does any recal a thread from a some time ago (more than year) that had frame with holes and slots in them?

the holes looked like this but were all over the frame IIRC

Now that is one sexy seat post, I guess that's going on my list to try once I get back down to the machine shop. Did you use a milling machine or drill and file.

I'd actually like to "Mexico" the crank (I think that is the right term). Basically mill out the flutes in the spider and crank arms. There was one on Ebay a bit ago, don't remember from who, but it went for a bit more than I was willing to pay. Obviously this weakens things but this is not a heavy rider and I am not a real stomper on the cranks.

Sorry, I thought you were looking for a photographic reference.

Hmmm...I could weigh the parts before/after and add it all up - but who's to say I couldn't lighten it up even further? I think a definitive answer is going to be impossible to give.

BTW, chainrings do not seem to be affected by drillium in the slightest. I think it's one of the best places to remove material, and even Campy themselves got rid of the inner webbing of NR when they went to SR.

BG: You could still drill out the other Portacetena holder; I like the two-screw version a lot. Works great!

BD63: I believe the Mexico milled cranks were Otis' handiwork. From time to time you do see originals out there on the 'Bay, but you're correct in stating they go for a pretty penny. Ah, but rare and quality never have gone for cheap...

Glenn: Drilled and filed on the SR seatpost, just like all the rest of my stuff. A milling machine is going to have to wait until June 15th rolls around and sets me free again

ready to tackle a set of Chorus area levers?

The "Mexico" cranks are completely re-profiled as well as opening up the spiders. Here's my version. This does lighten them, quite a bit of material comes off the arms. It's a lot of labor!

Yep that was them. I really wanted them but they went over my price limit. I think you fluted the backs of the crank arms too didn't you?

Wow!!! That looks beautiful!!! Is that all done by hand (no power tools)? Do you actually file the angular edge off the side if the crank?

The spiders and fluting is done on a milling machine. Profiling the edges is mostly hand work, files, die-grinder, sandpaper, and a bit of machining.
