a decorative rainbow map ottoman tray

by:Changda     2020-06-14
I recently upgraded my life with a K40 laser.
Then I upgraded the laser so that I wouldn\'t be blind or get an electric shock.
One of the first projects I did was the laser engraving roller coaster near me.
Then, as I went through the various laser groups, I saw people using lasers to remove paint from tiles.
This inspiration plus I have an Ottoman instead of a coffee table and I know what I have to do.
Make a decorative Ottoman tray!
So if you want to celebrate the month of pride, put something on your ottoman or couch, or just want to see something cool and join me on a journey full of first and fun.
Here is a list of tools and materials used in this project tool materials software/website, considering my tile size and number of colors, I need enough maps to cover the area of 12 inch by 18 inch.
I\'m going to do some fancy map stitching in order to do this, but first I need the map.
I went to the map image of Snazzymaps. com.
On the snazzymaps website, select the build map option from the top bar.
After clicking, the toolbar pops up and it\'s time to click.
For the map style, I search for the laser and then for The Epilog Laser thin line option.
I think it looks like the best but is free to choose other options.
I always talk about exploring and experimenting.
After the size setting is complete, both options are 100% so that we can get the maximum capture on the screen.
All appearances set the time to select the location.
This can be done with specific latitude and longitude coordinates or by searching for your location.
Because I\'m doing S. F.
I searched the Bay Area of San Francisco.
With the gorgeous display of San Francisco, I \'ve been playing the zoom game until the map looks like what I want.
It\'s time to screen.
In order to prepare a map large enough for my Ottoman tray, I had to slice to take screen shots of several bay areas.
Next, we combine the map blocks with Inkscape to prepare for the laser.
If you do not want to do all the screen shots yourself, I will attach the screenshots I took in this step.
If I say goodbye to snazzymaps and say hello to Inkscape, the screenshot is in it.
Here is how I capture the svg file to the laser from the png screen.
The first step is to import each screenshot.
After importing them, I use the tracking bitmap tool to get the tracking vector version of the capture.
Play with settings until you get what you like and I find them to vary depending on screen capture.
When you convert a bitmap, if you have more than two scans, it will spit out some grouped vectors.
Ungroup them, select your favorite scans, or flatten different scans into one vector using the combination function.
I didn\'t do it until all my screen shots were vectorized.
With the vector in my hand, I carefully arranged them and made a large vector map with a combination function.
I then made six rectangles of the same size as my tile and six rectangles of the same height as my tile width and tile spacer.
With these rectangles, I arranged everything so I ended up with 6 virtual tiles with spacing.
I Group the rectangle and send it to the back so I can arrange my map on the tiles.
Once I felt it looked good, I copied six maps and made my tiles using the intersection function.
As the tiles are all separated, I made a save file for each color tile with the file name matching its color.
Now that my virtual work is done, it\'s time to prepare the tiles.
Now we can finally discuss physics.
They need to be very clean in order for the paint to attach well to the tiles.
To get to the point of cleaning, I never knew before I wiped the tiles with paper towels and some acetone.
I put on my gloves to make sure I don\'t have any oil on my fingers after I wipe them clean. (Don\'t judge me.
We all have oil fingers, and that\'s how the crime scene fingerprint search works. )
The tiles were all clean and I had to shake the spray cans and paint them in batches by color.
The goal of painting is to have a uniform coating that is not too thick.
If it\'s uneven, your laser might not get everything off, you might get a disaster tile, as I did on the first green tile.
My trick is to spray the spray onto one side of the tile and then pass it through the tile until I leave the other side.
I move back and forth along the tile until I have a uniform coating.
This prevents you from building up where you pause a little to change direction.
Once you have painted several tiles of different colors, you may want to stop and take an art photo of your fabric. I know I did.
When the tiles are dry, I start making frames for them.
I had to make the frame for the Ottoman tray when the paint was dry.
With my table saw, I cut a piece of Luaan for the size of the mountain.
From there, I cut off some scrap Red Oak on the Mitter saw with a 45 degree cut on both ends to make the exterior of my frame.
The blocks were all chopped and it was time to stick them together.
I used the glue, clip and a square to make sure my frame was right on the wood background.
I left the glue to dry at night.
In the dry time, I started to remove the paint from the tile using a laser.
Now that the tiles are dry enough to be used in the laser, it\'s time to get ready.
I took my ice bag from the fridge and put it in my laser water cooling bucket.
When the water cools. (
K40 laser is cheap for a reason)
I started my laser control software K40 whisperer.
In the software, I adjusted my image position.
It can be difficult to arrange things on K40, so I used a vector rectangle like the size of my tile, made a fixture with cardboard, and wrote down the x and y positions.
As the fixture was ready, I placed a tile in the laser and adjusted the power to 36%. (
The K40 can not control the power supply with software and can only control the speed. )
I set the laser speed to 200 mm/s (
I don\'t think it moves so fast. )
I opened the advanced settings for the raster control and the Half Tone jitter that was deselected (
Stock K40 can\'t do grayscale, so it uses half tone jitter like the old dot matrix printer)
Because what we do is black and white, there is no need.
Then I choose to engrave the grating from the bottom up.
I like to do this because the part I am going to burn will happen if there is smoke contamination, not the exposed tiles.
I repeated the process with each tile.
I had a problem with uneven paint on the green tile, so I had to do another one.
Photos of my failed tiles are included in your viewing fun.
Now, thanks to the power of the Internet, you are not like me and don\'t need to wait a day to dry the glue and laser etching.
So let\'s keep laying this tile.
I had never laid a tile myself before this project, so I watched a very short video on youtube and was happy to go.
The point of it is that you use the tooth side of your edge spatula to make lines in the mud that go evenly in the same direction behind your back.
So with this new knowledge, I followed the instructions on the mud box to mix the water into my mud until it was as consistent as a cake icing and follow the carton God.
After the break, I mixed again without water and applied my mud to the board as I saw in the video.
As the grouting progresses, I use the spacing cross to work the tiles in place to make sure my tiles are spaced evenly.
Upon completion, I removed the spacer and I had 24 hours to write this instruction before I finished the project. . .
After 24 hours, the mud dries and the tiles are fixed in place!
I then use a transparent high temperature engine block spray paint to seal everything and protect the paint operation from high temperature items.
Once the paint was dry and cured, I mixed more mud and used a sponge filled in all the gaps.
I follow the instructions on the box and leave the excess grout on the surface for 15 minutes, then wipe the excess grout with a damp non-wet sponge.
It\'s another 24 hour wait party.
This project is waiting for all sorts of things to dry but now it\'s done and I can use my Ottoman tray.
This tray can also be used as trivet due to high temperature gloss coating!
If you have gone so far with me, you now have a great Ottoman tray that can also be used as trivet.
When the tray is not in use, it can be wall art.
Thank you for taking the time to check out my Instructure and my Ottoman tray.
If you make it yourself, I \'d love to see it, or if you have any city suggestions for future map-based projects, feel free to share them with me.
Happy Pride!
