Re-setting dropouts wider is not without some risk. Back in the late 90's I had my hand built Bill Vetter touring frame re-set by a local frame builder from 120 to 126 mm to accommodate one of them new fangled 7 speed freewheels. A month later the chainstay snapped at the braze point to the dropout while I was climbing the hills to Booneville, KY on the TransAm route.
PS- A local garage welded it back together and I was on the road again, and I've been touring with 36 hole Campy and Phil Wood road hubs for over 40 years with no problems!
