The workshop is very small, basically a corner of the prop shop. I am only using the tools that a regional theater prop shop would have in their possession. No machine shop here!!! Sword construction is essentially additive and subtractive sculpture in metal. I purchase my blades, do research and design my hilts, then purchase mild steel stock and set to work. Most of my shaping is done with 4 1/2 inch grinders with different wheels on them. I use these great fast grind Blue Fire grinding wheels from McMaster Carr, and sanding 120 disk flapwheels from Lowes. I have a porter cable random orbital sander with adhesive pads and 120 sandpaper, and a power drill with different types of Klingspor flapwheels. I also use piles of metal files and a carbide cutting tool for chiseling.
For the additive part, I am using a small ESAB MIG welder, The Oxy acetylene rig for bending and shaping and the occasional welding. I also have a small plasma cutter and metal cutting band saw and the trusty hack saw for trimming the metal to the right size. I have an anvil and a variety of hammers I have collected over the years, plus different forms I have made to shape armor.
My handles are made of wood, and I use the lathe most of the time to rough shape them and finish the designs with files and a dremel cutter. The only purely sword building tool I own is a Baldor polisher which has a 120 grit flapwheel on one side and a muslin polishing wheel on the other.
