Re: Bike Bobber
After roughing in the pit repairs with a dremel tool I finished blending them in by hand with a crescent moon shaped bastard file. A die grinder with a sanding disc or barrel will do the job too, but in this case a file can work just as good or better, and cheaper too. A good quality file properly used can last for decade's or more. To blend in the pit repairs I used long rolling twisting strokes of the curved side of the file. I worked both sides of the entire arc at once not in sections. Always use a bastard file with forward stokes only. Dragging the file backwards against the work surface only serves to dull the file prematurely. Also use a file card to keep your files clean and you will produce better results and your files will last longer, oh and your tool box drawer will stay cleaner too.
