First off i have heard that is illegal to pick up metal of the ROCK MOUNTS of RR lines. So let me say that is not were i got this metal. I picked it up at my work that happens to have its own set of tracks they use..........That said I have a box of scrap metal that ranges from spikes to 1" round bar about 8" long and a .5" thick round bar with a hooked end.......i plan to use this as my tool making ( tongs maybe even a small hammer) this is how i plan to practice all the basics..............but what else could i do to practice or should i say make to cut a rough edge in my skills be for i go and dive right in and get in over my head.
