Now that we have perfectly shaped triangles with numbers on them it's time to put it all together into a d20! The first step is to wrap the edges of each triangle in the copper foil tape. This gives us something for the solder to adhere to.



At this point you may want to consult a d20 or get some really good pictures from the internet, because the location of the numbers is very important.



Choose the first five triangles you will be using and place them face-down in the jig making sure that they are evenly aligned and that the flat tops of them form a continuous flat plane. I’ve found it best to brush some flux in the bottom of the little bowl that the triangles make before aligning them, then melt some solder so it drips on the spot where all five points come together. That will hold them firmly in place while you solder the other seams. Once you have all the seams soldered on the inside for the first five pieces, rotate the glass in the jig and add additional triangles and solder them in place on the inside.



Solder all the triangles together except for the last five pieces. These pieces will make a “lid”, so once you are done you should have a 15 triangle bowl and a five triangle lid, both of which are soldered only on the inside. Now, flip them over and solder the seams on the outside keeping the bowl and the lid separate. Once you have all the outside seams soldered you can clean the pieces with soap and warm water to get the flux off the inside. The last step is to place the lid on the bowl and solder it in place, then clean it again with soap and warm water and you are done! Congratulations!

While soldering the pieces together be sure that you are putting the correct numbers next to each other!
