Playing around with tungsten bits

got some cubes and putty from a Pinewood Derby supply site, weighed them before and after on a few if my small engines. I got my critter from 214g to as high as 302g. I brought my 0-4-2 Porter from 297g up to 362g. Now they should be more stable and pull a little better. submitted by /u/yeehaw13774 [link] [comments]
