I am finally ready to make my first lightsaber, and I want some people with experience to look over my parts list before I order. So my plan is to have the main body of my lightsaber be MHS parts and then I am going to make the back couple inches of the lightsaber on my own along with the blade holder, (ordering MHS parts if I end up not being able to make that work). So aside from the fact that there are parts missing to make a complete lightsaber body, do I have everything that I need to make a lightsaber?

-Acrylic Chassis Disk for NB/18500 1.15 ID parts
-Luxeon Rebel Star
-Star thermal tape pad
-Collimator Lense 8.7 deg viewing angle
-Luxeon Rebel Lense Holder
-.5ohm 3w resistor
-Premium 28mm Speaker
-TrustFire Protected 3.7V 2400Ah 18650 Lithium Battery
-Charger for the Trust Fire
-1/16, 1/8/, and 3/18 Heatshrink
-MHS ribbed extension
-A retention Screw (8/32)
-Nano Biscoti V2
-A Momentary Switch (no idea which one to get)
-MHS Extension Bland Style 1
-(I also don't know what heatsink to get)
-(I have hoby wire, but do I have to use a certain kind, same goes for the solder)

Thank you for reading and any help you could give would be greatly appereciated.
