My new bike frame is starting to take shape. This is where I'm up to. Tube delivery from Reynolds. More tubes from Ceeway and some bits from Pragon Machine Works. First stage is to check to see if the tubes are striaght by rolling them on the surface table, any bend will be placed in plane where it will be least noticable. Main down tube being checked for bends. Next on the list is marking all the butt positions. I've made a simple gauge to measure the positions. Butt gauge.Dont snigger. Butt gauge in use on down tube.
