Mandrel Set of 28 Different Diameter Rods

28 DIFFERENT DIAMETER STEEL RODS IN INCREMENTS OF 1/64" FROM 3/32" TO 1/2" PLUS 17/32". 
This set comprises one of my favorite tools for working on pens. It's a great aid for burnishing dents out of metal caps and barrels; you can usually come close enough to the size you need to fit into your piece and roll or hammer dents out (using a soft hammer, of course). These rods also work well as the roller when burnishing. I've also used these with a little heat to straighten out plastic caps and barrels. Another thing they work great for is in the roll of a mandrel (clamped into a vice) for use when peening over the "U" shaped rivets used on a Waterman's clip. One end of each mandrel is flat and the other side has a small point, but the mandrels are not tapered; the sides are parallel. Mandrels are 4 3/4" long.
