Drillium images - page Two

Drillium images - Page three

Pages to show some examples of Drillium but extended to cover milling, routing and a few examples of pantograph work, the latter is mainly factory produced showing the maker's name but some people do have a go themselves. Please feel free to submit unusual examples of Drillium for insertion on these pages.

For a start, Chris Hutchinson (obviously, not a man to do things by halves!) relates that - "In the mid-‘70’s when Engers was King, reports of his bikes and time-trial  successes filled ‘Cycling’- the well-known weekly cycling magazine in the UK known affectionately as 'the Comic'.   Drilling holes in bikes became popular and lead to a little friendly rivalry.   I managed to get more holes in this Weinmann lever than a clubmate’s entire bike. In more recent times it was fitted to my wife’s bike! "

By contrast Stuart Henderson's Weinmann  brakes below are almost understated although he does drill the levers:

Here are some images of Drillium taken in or near the jumble at this year's (2012) L'Eroica. Some is home-done and amateurish and some factory production. My guess is that, for a starter, this seatpin is a home job as only three holes are in line.

Below is a neatly lightened Campagnolo gear lever which can be.....

........compared with these on a Mattollini which are more extreme - I have heard of levers drilled
in this way snapping across the narrow sides.

I have never seen this pattern on a Campagnolo chainring before so I guess it post-production.......

......as are the drillings around the fixing bolts on this one?

This Mattollini below has the hallmarks of a one-off job

This must be a 'one-off' job for the team captain

Images from Peter Kohler's 1978 Raleigh SDBU Time Trial Special (Reynolds 753) with a selection of drillium components in addition to the factory drilled out drop-outs. Total build weight 16.4 lbs!

Weinmann stirrup was bought with lever shown above and shows signs of being done by an amateur.
The double curves of the stirrup surface make this a very tricky operation.
The drilled rear-end was 'factory drilled' as standard on this model.

Peter had this 56T TA ring custom-drilled by Jon Williams to complete this build

Jon Williams also worked the components shown in the three images below
