So one night I am running my hand over the existing layout switches and track joints, Gargraves and Tubular Track, Ross Switches and there are all sorts of sharp edges, probably not good for Traction tires. Homemade tool time --
I took a 1/8 “ inch Black Oxide twist drill bit, not sure of the significance of Black Oxide, I had some Black bits and it broke easy holding twist/cutting end it with a pair of pliers with the smooth end in the vice, I shaped both ends of the smooth remaining piece, one to a point (Not to pointy) and the other end rounded to a half of a ball . Shaped by putting it in the Dremel (use a speed that works for you) and hold it against a file to shape, I used a Mill ******* file ( a Fine cutting file) about 1” wide and 10 “ long. ( If you want to try it before you file the ends .. break the bit off and use the chuck end on some sharp edges )
I also use it on new track I cut with a Harbor Freight 6" Medal Cut Off , Chop Saw.
Put the finished Bit it in the good old variable speed Dremel and went at all the sharp edges track joints and it did a great job for me.
