Metalworking and bracketeering
Enjoy following your mods, detailed posts and writing style. May I ask what tool did you use to cut the brackets you made and how did you bend them? Thanks
Thanks for the note. Depending on the application, I will use 1/16" thick steel or 1/8" aluminum, sourced from OSH or Ace Hardware. I first make the bracket in cardboard. Then, before any bending, I drill any holes with a simple, cheap drill press from Home Depot with some oil, to preserve the bit.
After that, I place the metal vertically in a bench vise with smooth angle iron on both vise jaws, to prevent the naked vise diamond pattern from marring/imprinting the bracket metal. I use a cheap hand-held hack saw with metal cutting blade to make the cuts. You can only cut so far in, about 5"-6" before the hacksaw top stops the cut from going further. I cut into the metal at certain angles, often using triangle relief cuts to allow the saw to keep cutting. After some experience, you figure out the cut angles in your mind before even starting. I'll use a DeWALT 12" double bevel miter saw with a ferrous metal cutting blade to cut smaller pieces more quickly than a hack saw.
Next is bending in the vise by hammering the metal with a rubber mallet or with wood against the metal and a heavy duty hammer or small sledge hammer. More rarely, for thick steel, I heat the metal up with a Map gass torch from OSH, which softens the metal to help prevent breaking and makes for cleaner bends.
Last, I'll grind the corners and the edges smooth on both sides with a cheap electric stone grinding wheel, followed up by more precise filing in the bench vise. Always file aluminum, don't use the stone grinding wheel because aluminum clumps up on the stone wheel, rendering it useless.
Media blast or sand and then paint or powder coat! Done!
