Margaux Larg from The Crepe Shack contacted me because she wanted a new sign for her food truck. Like her friends at The Cheesy Toast Shack, she was taking her food van to the Edinburgh Festival and Margaux wanted a sign to show they sell drinks as well as crepes.
A long sign
Margaux wanted a long piece of oak that would span the width of the van’s serving hatch. I asked Margaux how long she wanted it to be as the laser bed is 1200 x 800mm. When she said 8” long, I asked whether she’d be happy to have it made in two parts so they would fit the machine. Initially, she said yes, but the more she thought about it, the more she knew that she really wanted it to be in one piece.
A bit of imagination
In the past, I have managed to set up the machine so that I can pass long things through the ‘letterboxes’ at the front and back of the laser. This works best if the items for engraving are up to 15mm thick, because I need vertical space to raise or lower the machine bed to maintain focus on the surface of the material. If I use the letterbox, I can’t lower the material as it’s sitting on the machine’s casing. If the material is thick, I can’t raise the bed much which makes it difficult to focus accurately.
When Margaux said that the oak was 15mm thick, I knew I could do it. Ben brought the oak round to the workshop and I got to work.
Splitting up the artwork
As the machine bed is 800mm wide, I checked the artwork from Hasta Inc to see how I could break it down neatly to engrave it in sections. The total engraved length was 2261mm with a logo at each end and five words in between. I worked out that I could engrave it in four sections – first, the left logo and ‘hot chocolate’, then ‘coffee tea’, then ‘soft drinks’, and finally ‘water’ and the logo on the right. It was going to be a fiddle and take longer than if it were done in two pieces, but it would be worth it.
Engraving in sections
First, I slid one end of the oak into the laser. I held it against the side of the machine so that I could change the position of the wood easily for the next engraving.
I deleted all the artwork except for the left logo and ‘hot chocolate’ and created a rectangle containing them. This included space from the end of the wood to the left edge of the logo for positioning. Then I set up the laser’s origin at the top right corner of the wood and started to engrave.
When the first section was finished (see picture above), I set up the second section of artwork. To get the right spacing between ‘chocolate’ and ‘coffee’, I created a rectangle that started from the edge of the last ‘e’ of ‘chocolate’ and ended at the right edge of ‘tea’. The artwork breakdown picture above shows this clearly. Before engraving, I moved the wood deeper into the machine so that it protruded through the back ‘letterbox’ and aligned the laser head with the last ‘e’ of ‘chocolate’. Then I engraved ‘coffee tea’.
Next, I had to remove the wood from the machine and turn it around, feeding the unengraved end into the machine. I continued to process the artwork as I did for the first two engravings. This time, I rotated the text and logos 180 degrees so that it wouldn’t appear upside down on the sign!
Margaux was delighted with her new sign. She posted a photo on Instagram when the van was set up in Edinburgh and tagged me in so I could see it. It’s such a lovely piece of oak and it looks beautiful in one piece.
