Reddit mentions of K&S Precision Metals 9862 Round Brass Rod, 1.5mm Diameter X 300mm Long, 5 Pieces per Pack, Made in The USA

The Chassis: Most of the handle is MHS v2 (where the leather wrap is), and then both ends adapt up to MHS v1. Because of this I ended up going with Goth 3D chassis parts that are 0.99 OD. But they are modular pieces, so you pick and choose which ones you want. I needed to use spacers between some of the parts so that I could route the cables through, so I put spacers between all of them to look cohesive. Other than the Goth 3D parts, there are a few Skywampa, TCSS, and other various hardware bits. Everything is linked below.

Goth 3D

• Crystal Chamber part 1 in polished nickel steel
  
• Crystal Chamber part 2 in polished gold steel There is 1 LED in the bottom of this piece
  
• Chassis part 1 in plastic white - Soundboard Was perfectly sized for the Warsabers board
  
• Chassis part 2 in plastic white - Battery
  
• Chassis part 3 in plastic white - Speaker Had to mod the speaker so this would fit inside the handle
  
• Chassis part 4 in plastic white - Recharge port
  
• Chassis part 5 in plastic white - Spacer disc
  
  
  Excluding the crystal chamber parts, the Goth 3D chassis parts were all white, which was a mistake. Should've done black. So I painted all of them in a few steps. 1st was paint them flat black. 2nd was paint them graphite. 3rd was a layer of silver leaf Rub'n Buff thinned with enamel thinner and applied to just the outside to help it look more like metal.
  
  Here are the other pieces of the chassis with explanations:
  
  
• Skywampa 1" chamber part These are used as spacers between the crystal chamber and the chassis. Also helped with providing a channel for the wires.
  
• Skywampa 35mm Graflex to MHS connector disc. This is the disc between the blade holder and the MHS Chassis disc below. You need it to connect the two pieces together. It's not on their Etsy page right now so I can't link to it.
  
• TCSS Chassis Disc Style 4 This is the part that threads into the handle and holds a 2nd LED for the crystal chamber.
  
  The Skywampa and TCSS discs are treated with a combination of Aluminum Black and Ebony Rub'n Buff to give them that "weathered" look.
  
  Here are the various hardware bits to connect all of it:
  
  
• Crystal for the crystal chamber Picked one that looked right but was a little big, then reshaped it some to fit properly
  
• Brass rods that run the length of the chassis These were treated with Aluminum Black to look old. I also tried carbon fiber and steel rids but like the brass ones the best
  
• Steel spacers These are between the the fins, crystal chamber, TCSS disc, Skywampa disc, & blade holder
  
• Screws to connect the TCSS disc, Skywampa disc, & blade holder
  
• Crimp Beads These are the spacers between the battery, soundboard, recharge port, & speaker chassis components.
  
• Brass tubes between the crystal chamber and the TCSS disc. Don't remember the size though. These provide a little extra stability for the brass rods because they flexed a little too much for my liking.
  
• 5mm LED bezel Two of these, one on each side of the crystal chamber.

I bought these brass rods and bent a handle on the end about half way down and just push it in from the top and don't have to remove anything.
