Bats, Bats and More Bats! The Halloween Type!

by Skip…

Inspired by David Picciuto’s Rockler-sponsored video on making puzzles using a laser, we decided to download his puzzle template, fire up the Full Spectrum laser and make a puzzle. In the past couple of years, we have produced holiday-themed puzzles using the laser (2016 Ghoul,  2015 Christmas Tree, Thanksgiving 2016, Halloween 2015  ).  So with Halloween approaching, it was time to put out another puzzle.

Bat puzzle

 

I searched the internet and found a Halloween image with some bats, and sized it to fit in a 10 inch by 7 inch space. Then, using the laser in raster mode I burned a light image of the subject on a piece of 1/8 inch thick Baltic plywood.  I then loaded up the puzzle template, sized it to fill the 7 inch by 10 inch space, and in vector mode with 100% power and 60% speed, cut out the puzzle. Oh, before laser cutting, I covered the raster image with painters’ tape to reduce burn residue from collecting directly on the wood surface.  I peeled the tape off after the puzzle was cut.

So why did I pick bats this year?  I like bats. They are high tech, insect-eating machines.  If you get up close and personal, they are really kind of cute.  We have several bat houses on our UF campus and it is really fun to watch them come out at dusk to do their thing…. eat insects!

In a September 2016 blog post by Christina Wang, Spooky Symbolism: The History and Meaning Behind Iconic Halloween Images, Christina writes

“Bats have long been associated with mystery, evil, death, and the supernatural. They’re only active at night, plus they live in caves (which evokes the underworld). Vampires are also often said to transform into bats, a connection popularized by Stoker’s novel and the many Dracula films.  One theory for the link between bats and Halloween has to do with the festival of Samhain. When the Celts celebrated the end of the harvest on October 31, they would light bonfires to keep evil spirits at bay. This practice would attract insects and, in turn, bats.

For some great Bat Facts (and to see baby bats in blankets) go to Brandon Keim’s Wired article, October 31, 2012 entitled: Tricks and Treats: 12 Amazing Things About Bats.”

Back to the puzzle: after removing all the tape and cleaning up the parts, I turned the puzzle pieces over to my wife for PLPPP (POST LASER PUZZLE PIECE PROCESSING).  I thought the image I laser-printed on the puzzle would make it easy to put the puzzle back together before painting…NO! It took my wife a couple of hours [days, actually…J]  to reconstruct the puzzle. The image was too light and the puzzle pieces are so uniform that it made it really difficult to put the puzzle together.

Once it was together, I sandwiched it between two boards and flipped it over. I covered the back side with painters’ tape to hold it together while my wife painted it, using acrylic paints and glitter. I followed this up with a couple clear coats of acrylic spray.  My wife decided to extend the challenge she had undergone, and painted the puzzle in a fashion to keep the difficulty at a high level.  Nobody is going to quickly solve this puzzle like a bat out of you know where!!

 

Halloween Woodworking

An inspiration from one of the You Tube woodworkers: Mitch Peacock’s Hallowood 15 challenge. We haven’t risen to the level where we are confident to take on You Tube challenges yet; maybe next year. But perhaps we can participate through a blog post.
We are still learning how to use some of this new technology, so we set out to see if we could make another tray puzzle, this time with a Halloween theme.

My wife drew a jack-o-lantern outline for me to vectorize and input to the laser software, so I could try cutting out a puzzle with a Full Spectrum laser. My ineptitude in dealing with all the software left me high and dry. I could get the drawing scanned and saved in an XPS format, but when I pulled it into the software all I could do was get a raster file, which I could use to burn an image on the wood but not cut the wood. Evidently you need to use drawing software that lets you save your file in a vector format. So I used the drawing software that came with the laser, albeit pretty simple, and I was able to hammer out what looks like a jack-o-lantern outline with lines added for the puzzle cutouts. My wife can then add embellishments to make it look like a real jack-o-lantern.

A little history to equate this project to the past:
According to the History.com website

“The practice of decorating jack-o’-lanterns [the name comes from an Irish folktale about a man named Stingy Jack] originated in Ireland, where large turnips and potatoes served as an early canvas. Irish immigrants brought the tradition to America, home of the pumpkin, and it became an integral part of Halloween festivities.”

The History.com website has the story of “Stingy Jack” and many other great current and historical content related to Halloween including a video by a master pumpkin carver. The carving of these jack-o-lanterns thus finds its beginnings in Ireland and Britain in the early 19th century. Lighted gourds may date back over 700 years, but not as a Halloween practice.

So here was the procedure for making the Hallowood puzzle:

• Produce a drawing using a vector format. I used the drawing software that came with the laser engraver. It didn’t give us a lot of avenues for creativity, so the pumpkin is pretty simple. My wife embellished it, which made up for the simplicity.

• Laser cut the pattern. I used 7 passes for a laser setting which was perfect for cutting through the 1/8 inch hobby plywood piece. The pattern was about 8 inches by 8 inches. If I had a better grasp of drawing this pattern I would not have cut out each tooth separately. The teeth were too small to be effective puzzle pieces. We left out the teeth and my wife ultimately painted a yellow background on the tray surface. The laser produces such a fine cut that the puzzle pieces fit very tightly in the tray. I had to do some sanding to loosen them up a little.

• Remove the puzzle pieces from the frame and lightly sand the pieces. Cut the frame to size and cut another piece of 1/8 inch plywood to form the back of the tray. Glue the tray back on the frame. Round over the corners, sand and apply a sanding sealer, in this case spray lacquer. Apply a sanding sealer to the puzzle pieces.

• Put the puzzle together and paint. This was the tricky part. The triangles for the eyes and nose were not exactly the same; another result of not knowing what I was doing when I drew the puzzle in the vector format. So once the pieces were arranged properly, my wife came up with a way to paint the pieces so their orientation would be obvious.

• Sign, date and apply a clear coat and give it to some deserving child of appropriate age.
