double marble puzzle  -  polycarbonate sheet cut to size
The goal of this classic marble puzzle is to be able to place the marble in the holes on both sides of the block.
In the first contact with the puzzle, many observers will try to tilt the square and deposit the marbles in the hole.
They will soon find that this is not allowed to happen at the slope of each hole.
Usually, there is a partition in the middle of this puzzle to prevent the marbles from touching.
I find that I like the sound of marbles when they are together, and without this partition it makes the puzzle more difficult.
Please read on and learn how to make your own double marble puzzle. You need something to make this puzzle.
Material: Tools: I glued two 3/4 pieces of oak larger than my template.
Once dry, align the edges on the table saw or joint.
Draw a registration mark in your wood space.
This will help you to stick everything together in the next steps.
Cut the pieces into three pieces with a table saw or band saw.
1/4, just over 5/8 (
This size is based on 5/8 marbles), and 1/4 inch.
Glue the connected template from step 1 to the internal slice.
Cut off this curved part.
Note: I have updated the template to show the additional 1/4 that is not removed here.
Follow the template and your will be like mine.
Track inside sand.
The spindle sander would be great here, but since I don't have a spindle sander, I polished it by hand.
Apply a small amount of glue on each surface to avoid squeezing out the track.
If you see any, remove as much as possible.
Use a saw or connector to square each face and trim it to the final size.
This is probably the most difficult step.
I center the holes on both sides of the puzzle with a 5/8 shovel drill.
You want these holes to be almost horizontal.
When I measured and marked the holes in the puzzle, I made an inner hole 7/16 below the top of the puzzle, and an outer hole 1/2 below the top.
This should cause about 4 ° angle from the horizontal direction.
Once each hole starts with your shovel drill, connect the holes with a smaller drill hole from the outside of the puzzle.
Once this pilot hole passes, the hole is connected using the shovel bit.
I used my Dremel tool to clean the holes with a small drum sander attachment.
Use a 5/8 pin to plug each hole.
Test the depth of each plug so that each marble can be placed in each hole.
Once you know the necessary depth for each hole, stick the pin in the appropriate position.
If your hole ends up being slightly larger than 5/8 as mine, mix some sawdust with glue to fill the hole.
After the glue is dry, remove the remaining plug with a band saw or a table saw.
Use a sander to flatten each end of the puzzle.
Bypass each edge of the block other than the top.
This is the place that will connect to the polyester.
Once the final size of the block is found, cut the polycarbonate sheet to fit.
Use the right size drill bit to finish the nails and drill the holes through your pc into your block.
Paint a few layers.
Use fine sand sandpaper between the coatings to get a shiny finish.
Use a window cleaner to remove all dust and dirt from your polycarbonate.
Before connecting your polycarboante, make sure all the dust is cleared from your puzzle.
You can do this with an air compressor or a simple air tank.
Once cleaned, insert your marbles and nail your polycarbonate in place.
If you haven't figured it out yet, all you need to do is put it on the desktop or on the floor and rotate it.
When you rotate the block, the inertia of the marble causes them to rise to each side of the block and stay in the hole.
