As well as being addicted to bright and shiny Italian things, I also love a nice bit of drillium to perv at
I'm thinking of taking the plunge and drilling my record chainrings
Fortunately, I can scan the chainrings and draw all the drill positions. We have a CNC router at work so I plan to drill a master template to use as a guide. Unfortunately, I can't use the CNC to actually drill the rings as I don't trust it to give a perfect fit on the ring, a fraction of a mil out and its not going to look right.
My plan is to use the master template, fix it to the ring and then use a pillar drill to drill the holes. Take off the template and countersink the holes.
Has anyone else tried doing their own drillium and are there any obvious pitfalls?
Or, some pics of good pervy drillium would be welcome
