For the items you mentioned like motor mounts and etc. the 4 1/2" angle grinder is absolutely the best, smallest, portable and powerful tool for small jobs. Get a good one. Cuts quickly thru anything. You can clamp any part in a vise and cut. These will also fit into places that a portable band saw will not if you are cutting something off in a tight space.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn |
