About a year ago a friend of mine saw a very nice Sonic Screwdriver Wand made by Maranda Li aka Praeclarus Wands.
Due to those being sold out she asked me if it would be possible for me to make her one, which is what I'll be attempting to do. Having talked to her about possible manufacturing processes, materials, designs and more, we decided to go with a slightly more detailed design consisting of the Tenth Doctor's (aka David Tennant) Mark VI Screwdriver as the handle and Romana's Screwdriver as the wand part.
Design and make a Sonic Screwdriver Wand with a decent amount of detail.
This instructable makes use of (power) tools, knives and other scary stuff.
These tools can cut or otherwise hurt you, potentially causing serious harm.
Always wear eye protection and be extra careful where your fingers/hands are at any given moment. In general, before doing each step, think about what you're doing, which tools you're using and what potential dangers are involved. If you are not experienced with the use of the tools, get help from someone who is.
Additionally, as a lot of sawdust and spray paint is involved at certain stages, using a filtering facepiece (painter's mask or similar) is advised. Your lungs do not take very kindly to lots of sawdust and paint particles.
And while at it I would like to give you a very nice description/quote by Adam Savage from Mythbusters on this subject:
"The table saw is unique among all tools in that it terrifies me more than any other. I never use a table saw without picturing my fingers flying across the shop. I am not exaggerating even a little bit. I picture -no joke- somebody walking in the door unexpectedly and tripping and spilling a bucket full of marbles and grease, and all of a sudden I lose my footing and land my chest first on the table saw blade. Every time my hands are within a foot, every time my body is near a running table saw, I am constantly checking my center of gravity, my balance, and keeping both feet on the floor. I am moving so that I can get myself out of the way. I think about kickback. All of those things are running through my head. So because I have never lost that terror of the table saw - and I never want to lose it; The moment I feel comfortable in front of one is the day I am going to lose a pinky." - The Adam Savage Project - Shop Safety - 2/26/2013
Be genuinely afraid of your tools and you will very likely think twice about what you are doing, drastically reducing the chances of injuring yourself. By the way, the video is a very nice video on shop safety, it's really worth a watch. The shop safety part starts pretty much where my link says it does, so you can just let it run and listen to it.
