Pearls Spear from Steven Universe.
First let me ask you to please view the following tutorials/. I found both of them incredibly helpful.
The above link made this spear very simple. His approach to the corkscrew and the end are beautiful.
Her approach to a translucent spear is excellent. I will say painting translucent colors is difficult and should not be rushed. Like I did. Their is a fine line between translucent and opaque.
Most of my design is based on the thinking that Pearl is wielding a Naganita. That is debatable. But I feel that is what she is using. Just a very fancy one, with a corkscrew.
But anyway. I started with the below image. I scaled Pearl up to 6 foot 4. because that is how tall I am. And yikes the spear is huge.
So below are my measurements. Is it going to be one big prop.
I am not good at free handing, so I designed the blade end on my computer. Printed it out, and used that as a pattern for the spear.
Below is a test spear I made. I used file folder because I have TONS of those. I think it looks ok. It is the wrong materials. But I was able to mock it up for free. I learned alot about doing the corkscrew.
For the main part of the tube I used an acrylic tube, 6 foot long, 1.5 inch outer diameter and .15 inches wall thickness. It was very sturdy. And very light. I really like this prop. It is very different then anything I have made.
So I am always nervous. I try to break things down into tests, or experiments. How much can I do, where if I fail, it is flexible. So I made a really long spiral pattern. I cut it out.
That patern along with the spear head ended up with this. I like it.
I realized the spiral I printed out was WAY too long. So I ended up with this long. I used PETG as the final material. A clear thermoplastic. Thermoplastic means you can heat it and shape it. AWESOME. Now this stuff isn't worbla, you can't do crazy bending. But you can do a corkscrew. Now just a heads up. The below pic. The spiral is going the wrong direction. I had to cut it off and flip it. Argh. I was hoping for no seams. But I had one. Drat.
The PETG is real easy to work with. You heat it up (with a heat gun). And shape it to what you want. I will recommend holding it once you have the correct shape. It will spring back to the wrong shape. Also when you make the corkscrew, I recommend adding a lip on the inside of the corkscrew to make for my gluing surface area.
I also had problems getting the spear head to be smooth. So I made a tool to go on the inside to smooth it out. Yes, behold, a sock on a stick.
Now on to the bottom of the spear. I built this very similar to Ozpin's cane. Everything is on one big screw. I am not good a freehanding things. So I took some foam. I cut the correct angle in the foam. I spray glued some sandpaper on it, 60 grit. And I spun a piece of foam around and around until, BAM cone. I am very happy with how the cone came out. I tried to hand carve a cone, yeah nope.
I then covered the cone in 3 layers of worbla to make a nice strong cone.
I then removed the foam. I would love to say it just popped out, but no. I used a fork and knife to get the foam out.
Below is the fun part. I wanted no visible fasteners. I took 2 coupler nut and put then on a long screw. I placed a piece of blue tape over the end. The tape was to try to keep the screw threads clean. I then made the little jig below to mount the couplers nuts inside the cone. I used a bucket, a bench clamp and some foam board. I spent a long time getting the nut as perpendicular to the cone as I could. I then filled the hollow cone with epoxy. And once that cured I filled the rest with fiberglass and more epoxy. I like epoxy.
The 'dish' was made the same way as the cone. I cut some foam, glued some sand paper. And used that to cut a nice little dish. I covered the entire thing with worbla. And drilled a hole through the dish. I took a piece of scrap dowel I drill a hole through the dowel. And bam. The end is done. A couple coats of wood glue. A little bit of sanding. And I had a nice smooth end.
I painted the screw part. I attempted for a translucent paint. I rushed it. I used too much. And BAM opaque.
I used pink spray paint for the bottom half of the tube. In the pic below you can see a few details I added. They are made of a PVC tube. I cut the appropriate shape. And using a rasp I smoothed it down.
I then screwed the cone onto the thread. I slide the dish down. I slide the dowel down. And I screwed the bottom assembly tight. I wrapper the dowel in a couple layers of duct tape. Well actually I put too many layers, so I had to take a few layers off. Probably for the best. I ended up with a very tight fit. And jammed it in the bottom of the tube. AND DONE.
