Hocus Pocus book

This was by far my most ambitious project so far! A while ago, my wife asked me if I could make a replica of the spellbook from the movie "Hocus Pocus". If you haven't seen this movie, I definitely recommend it. Even though it's a family-friendly Halloween movie, it's not childish.
Anyway, I knew this would be a bit more challenging than the books I made so far (especially the ornaments), but nothing that couldn't be done. So let's get started!


I also documented the entire build process on video. Many hours of footage, many hours of editing, and I managed to process it into a 20-minute video! In case you're wondering, I recorded it using a Canon Legria HFR506 camcorder, edited the video in Lightworks and recorded the voice-over with a USB microphone and Audacity.



Materials

  • Sewn kraft paper sketchbook
  • 3 mm thick MDF
  • Cardboard
  • Air drying clay
  • Apoxie sculpt
  • 25 mm glass dome
  • Kraft paper
  • Unbleached hemp string
  • PVC foam plate
  • Super glue
  • Book binding glue
  • Epoxie glue
  • Hot glue gun
  • Thick needle
  • Molding silicone
  • Polyurethane resin
  • Foamcore board (for the mold)
  • Spray primer
  • Acrylic paints
  • Acrylic varnish
  • 8 mm neodymium magnets
  • Red felt
  • Gauze

The ornaments
Like I said, the ornaments would be quite a challenge. There are the four coiled-up snakes at the corners, the two snakes near the spine, the clasp on the front and a hand on the back. The hand isn't shown in detail anywhere in the movie, so I would have to improvise a bit.
I decided to make one of each ornament, and then mold them in silicone so I could cast multiple copies of them. I used a combination of PVC foam sheet and Apoxie clay, and took my time until I was satisfied with the sculpts.



Then, disaster almost struck. I made a silicone mold, and expected the silicone to be cured the next day. However, when I checked, the silicone was still a semi-liquid, sticky mess! I waited a few more days, but it simply didn't cure any further. What had happened? I suspect the catalyst for the silicone had expired. When I checked the bottle, I noticed some crystals on the bottom. I decided to wait a bit longer, but to no result.
So I ordered some new silicone and catalyst and started over. I removed the semi-cured silicone, and to get rid of any remaining liquid stuff, I brushed some catalyst over it and let it cure, so I could remove it easily. I made a new mold, and this time it worked fine. The next day, the silicone had cured as expected and I could start casting.



I used polyurethane resin for the ornaments. Four coiled-up snakes for the corners, two snakes for the spine, one clasp and one hand. When the resin had cured, I first cleaned the casts thoroughly and then sprayed them with a primer, followed by a dark gray acrylic basecoat. After the basecoat had dried, I applied a black wash, silver drybrushing and finally a satin clearcoat.



One ornament that required a special treatment was the clasp. To make it lock, I installed some neodymium magnets in it. Before painting, I carefully drilled some holes in the back, and glued the magnets in place with super glue. Magnets will be embedded in the book cover as well.

The book
My wife wanted a book with brown pages. This wasn't easy to find! There's plenty of sketchbooks made from brown kraft paper, but they are always either spiral bound or very thin. It took me some searching, but finally I found one on Ebay!
When the book arrived, I noticed the spine wasn't glued. The pages were stitched together, but no glue. To make sure the book would be strong enough, I applied a coat of book binding glue to the spine, followed by a strip of gauze, followed by another coat of glue.
One last thing needed to be done, and that was some sort of headband. I have tried making them myself in the past, but it didn't look too good. A great alternative was a strip of red felt, glued to the spine.
I didn't take any pictures of this, but it is shown in the Youtube video.

The cover
The book cover is made from 3mm thick MDF, and cardboard for the spine. The spine needed to be rounded a bit. I did this by glueing a few layers of thin cardboard together on a piece of PVC pipe, and letting it dry for a few days.
Another prominent feature of the book are the stitches, and the eye. The eye is a stock photo of an eye, printed on photo paper, and glued to a glass dome. The eyelids and stitches were sculpted directly on the cover.


I sculpted the stitches out of air drying clay. For the eyelids, I used Apoxie sculpt. After the clay had dried, I carefully drilled out the holes in the stitches with a 2 mm drill bit, and cleaned them up from the back of the cover.
I didn't take pictures of it (again), but there are six small magnets around the eye. I drilled 8 mm holes in the cover, and put the magnets in them, sandwiched between two sheet of paper on the front and back. These line up with the magnets I put in the clasp, so they keep it in place.
After glueing both cover boards and spine together, I used my wrinkled kraft paper technique for creating a faux leather effect. Usually, I try to use one single sheet of paper for the entire cover, but in this case it was easier to cut it into several pieces. The reason I try to use a single sheet is so you don't see the seams between the sheets. If this case, however, I could hide the seams in the stitches so they wouldn't be visible anyway.
And then it was time for the paint job! As usual, I started with a black basecoat, followed by a layer of brown. I used a mixture of burnt umber with a bit of pyrrole red to get a chocolate-like brown. After it had dried, I rubbed a very thin coat of yellow ochre over it, followed by a bronze drybrushing.
The final metallic drybrushing makes a huge difference! I have tried several colors (copper, bronze, gold, silver, ...) but bronze and copper look the best. I have also experimented with different color combinations the last few months, but that's something for a future post.



Before the final clearcoat, I sewed the stitches. First, I opened up all the holes with a thick needle, and then I sewed them using unbleached hemp string. It wasn't easy, sewing relatively thick, rough thread through small holes, but the result looks pretty nice. I glued the stitches in place from the back with a hot glue gun, and then trimmed everything with a sharp knife.
Next, I sprayed the cover with matte acrylic varnish. In the past, I have used satin varnish, but I think matte looks a lot better.


Putting it all together
And now it's time for the final assembly! I first glued the cover to the book. I needed to take special care to make sure everything was lined up properly, because otherwise the book wouldn't open afterwards. I glued on one side at a time, and pressed everything in place firmly, making sure there weren't any air bubbles. I put the book between clamps to keep everything together as the glue dried.


Next, I put the ornaments in place with epoxy glue, one side at a time and waiting until the glue was fully cured before switching to the other side (about 1 hour).


And then finally, the clasp! I glued a strip of leather between the clasp and hand, glued some felt to the inside of the strap and the clasp (not the hand), and finally glued the hand to the back cover.


And here's the final result! It took me a lot of work, but I think it turned out very nice. My wife is very happy with the result.

My Prusa I3 MK3!

In March, I finally placed an order for a Prusa I3 MK3 3D printer. I had been planning to buy a 3D printer for a while. At first, I wanted to get one of those cheap I3 clones, but after reading a lot of user experiences I decided to spend the extra money and get an original Prusa I3. Bottom line is: the cheap clones are ok printers, but you have to spend a lot of time to get them to print more or less decently, and I didn't want to do that.

The waiting game
So, like I said, somewhere early March I placed the order, and the estimated shipping date was mid-April. That gave me plenty of time to study the assembly manual and read user feedback. I found out some people had some trouble getting the frame all straight and perpendicular, but luckily this wasn't a problem that couldn't be fixed.
In the meantime, the shipping date moved forward a few times. The flu season hadn't spared the people at Prusa Research, and late April I finally got a shipping notification. Woo hoo!

The build process
I have documented my entire build in a series of YouTube videos. The entire assembly manual has nine chapters, so I made it a nine part video series. Also, this is the first time I'm actually talking in front of the camera, something I haven't done before (my other videos in wich I talk are all voice-overs). I'm not exactly the best public speaker, but I think I did a decent job without sounding too much like a blabbering idiot.


The entire build went pretty smooth. The mentioned problem with the frame geometry didn't happen to me. One this that worried me a little bit at first were the linear bearings on the Y-axis. During assembly, they were quite noisy, and I was worries I had over tightened the screws to hold them in place. Nothing that was beyond fixing, but if I indeed damaged them it would mean ordering new bearings and waiting some more. Luckily, during printing the noise is gone. I managed to damage one part, though. When I tried to snap the spool holder in place, the bottom part that snaps around the aluminium frame broke, and it doesn't properly stay in place. Not a big issue, since I'm also building an enclosure with a separate spool holder anyway.

My experience so far
I've had the printer for a few months now. I've printed quite a bit, and here's what I've encountered so far.
First of all, 3D printing isn't plug and play. Sorry, it isn't. It often requires some experimenting and trial and error to get things right. I've already experienced a few jams that required me to disassemble the entire extruder, and I'm glad I bought the kit and not a preassembled printer.
I have also built and enclosure out of Ikea Lack tables, so I can print with ABS and HIPS. There are a few problems with this. First of all, Ikea Lack tables are very unstable; especially when printing small parts, where the extruder has to move back and forth rapidly, the entire enclosure shakes a lot. I managed to get this more or less under control my attaching some steel corner braces. Second, the printers jams easily inside an enclosure with the doors closed. Apparently, this has to do with the design of the extruder, it has insufficient cooling, wich causes something known as heat creep. I'm not gonna go into too much detail, but it's a bad thing.
Prusa has designed a new extruder body with improved cooling, so that's on my to do list: printing the new parts, and then rebuilding the extruder. Again, glad I bought the kit, because I basically have to take the entire extruder apart and reassemble it with the new parts.
Overall, I'm quite satisfied with the printer. I've had a few problems, but this also happens on printers that cost three, four times as much.

Oogie Boogie dice

This is going to be a short and simple one. With this prop, I introduced my wife to foamsmithing. She was working on an Oogie Boogie costume, from Tim Burton's "The nightmare before Christmas", and wanted a pair of dice to go with it. In the movie, Oogie Boogie rolls dice with skulls on the faces. A perfect beginner project!


Materials
  • 10mm EVA foam floor mats
  • 2mm EVA foam sheets
  • Contact cement
  • Book binding glue
  • Acrylic paints
  • Satin varnish
  • Hobby knife
  • Band saw
  • Dremel with sanding drum, grinding bits and cutting wheel
Making a cube
To make a cube, you could just stack together sheets of foam until you get the right thickness, but that would require a lot of foam, and if you're using floor mats with a texture, you'd need to sand it away. I didn't want to do that. Instead, I cut six squares for each cube (I made two) and bevelled the edges at 45°. This is done easily with a band saw; if you don't have a band saw, it could also be done with a bench sander or, but that's a bit trickier to get it right, a Dremel.
The squares were then glue together with contact cement. No need to sand away any texture, and a perfect cube!


The faces
This is where my wife stepped in. She had downloaded a template for the faces and traced them all on 2 mm thick foam sheets. Next, she cut them all out and glued them on the cubes.


The next was done by me again (she doesn't like to use power tools). With a grinding bit on my Dremel, I cut out the eyes and smoothed the edges and corners a bit. I also added some scratches and cuts with a cutting wheel. Of course, I forgot to take a photo of that, but you can see it in the next step.


Painting
This was, again, done by my wife. First, the dice were primed with book binding glue, and then got a dark red base coat. After it had dried, the eyes and scratches were painted black. Finally, the entire prop got a coat of sating varnish.


And here's us, with our costumes and the dice, of course, at Elf Fantasy Fair Haarzuilens.

What's happening?

It's been a while since my last post (wich was right after Halloween), so I thought I might bring you all a bit up to date. I've posted some stuff on my Instagram page in the meantime to show some of the stuff I'm working on, so here's an overview of what I've been up to the last few months.

Workshop upgrade
The most important thing: I finally cleaned out the garage and did some necessary renovations and upgrades. Patched up holes in the walls and ceiling, painted everything, installed new lighting and extra power outlets and sorted my tools and supplies a bit (actually, I'm still in the process of doing that... It's a never ending story!).
I hope to keep everything more or less clean and tidy from now on, and especially avoid dust as much as possible. Before the upgrade, there was dust everywhere, and it was almost impossible to clean out! Besides dust from sanding and cutting, the bare plaster walls had holes in them everywhere and contributed their share to the mess.
And finally, the lighting and electricity were insufficient. An old fluorescent light, and only a single power outlet and lots of extension cables. The fluorescent light got replaced with LED light bars, and I installed a series of new power outlets, with their own circuit breaker. Bye bye fire hazard!

Etsy shop on hold
For now, I have put my Etsy shop on hold. This summer, I will attend three art markets, and I want to have enough stuff to put on display. Last year, I did one art market, and it was quite succesfull. I'll attend the same one this year, and two markets at fantasy events, both in the Netherlands. In August, my shop will reopen.

Books!
Those who follow me on Facebook or Instagram already know this, I'm working on more sketchbooks. I'm always trying to come up with new ideas, concepts and color combinations, and I'm trying to expand my themes beyond the Necronomicon/Lovecraft universe. For my faux leather technique, not all color combinations work, and it's a lot of trial and error. Although I made small test pieces to test something out, it still might turn out entirely different on a complete book.

Props!
Last year, when I did my first art market, I had one prop weapon on display, but it wasn't for sale. Some people were a bit disappointed, so I decided to build some prop weapons to sell. At the moment, I'm building a few maces, a hammers and a flail.
I did intend to do full build logs, with pictures and video, but the problem is, I always tend to underestimate how much time a project takes. You'd think I would have learned by now, but I didn't. I've got a lot of photos and video footage on my pc that needs processing, but I simply don't have the time.
So here's the plan. I won't be able to finish the build logs I had in mind. Sorry, not gonna happen. It would take me too much time to process all the images and video footage, and then write blog posts. After the hectic period I'm in right now is over, I'll post an overview of some of the stuff I built over the past few months, with some pictures, and I hope I'll be able to resume writing proper build logs after that.

New tools
A while ago, I bought a 3D printer, a Prusa I3 MK3. I've already got some videos of the assembly up on my Youtube channel, I hope to complete the remaining chapters soon. I'm glad I bought the kit; not only did I save 200 euros, it's very useful to know how to take it apart and put it together again. I've already had some issues with the extruder, and it's much easier to fix if you built it yourself.
In the future, I plan to build a simple laser cutter, partially with 3D printed parts. This will come in handy for cutting cardboard and thin craft foam. This won't be a tool that can cut acrylic or plywood, perhaps one day if I win the lottery...

Follow me
I know I'm not as active as I want to be on this blog, but writing posts and editing photos takes time, wich is something I'm already short on. If you want to keep up with my work, here's where you can follow me:
The next events ahead are Elfia Arcen and, of course, Halloween. I do have some cool new things in mind to build, and I hope to find the time to do complete build logs again.
