Build at your own risk. This article accepts NO responsibility for errors you make, injury, fire, explosions, legal ramifications, or failure to use the correct materials for construction.

Always use care and supervision when lighting any kind of explosive or firework, and check your local laws regarding what is legal for you to light in your area.

Always have on hand:

  • A fire extinguisher
  • A first aid kit
  • Access to a hose or water
  • A plan for emergency injuries
  • NEVER allow children to ignite fuses or explosives
  • Always make sure fireworks have burned out completely before touching or cleaning up


Do you do home firework displays?

  • Yes! We have plenty of land and always plan well and keep safe.
  • No! We watch local displays in the community,and burn sparklers at most.

Step 1: Gather Your Supplies

Go to Home Depot and your local plumbing store and get all your supplies together. Home Depot will cut everything you need, all you have to do is ask! Plan on spending about $120.00 USD on what you need.

Step 2: Build Your Racks

Attach (1) 1-ft piece of 2x3's to each end of (1) 2ft 2x3 piece, with (4) 3 inch screws

Then take (4) pieces of the 27 inch 1x4, and screw those to the side of what you just built, (1) across the bottom, (1) across the top on each side, using 2 inch screws.

Now you have a 10-shot mortar rack. Combine as many or as little as you'd like. For our project, we obviously have 50 shots, or 5 racks combined.

Wood Plugs

Step 3: Prepare Your Plugs

One at a time, take a tube and line the inside of one end with a small bead of Liquid Nails. Hammer the wooden plug into the glued end of the tube.

Once the plugs are in, secure them even further with (2) 1 inch screws on each side.

Repeat for each tube.

Place your tubes into your racks!

Step 4: Fan or Angle Your Racks for the Final Step

Set the racks next to each other standing straight up, using the scrap 1x4 pieces placed between the tops of each of the racks, to make your spacing.

Next, attach the 20-inch length of 1x4 to the bottom of each side, starting in the center. Secure the piece with (1) screw into each rack on both sides of the entire project.

Next, attach the 2-inch length of 1x4 to the top of each side, with (5) screws, do this for both sides as well.

Remove the spacers. You now have a fanned or angled mortar tube launcher!


When your rack is finished, enjoy its durability. We blasted it off with 50 shots right off the rip with no problems. Seriously, this thing will take a beating and give you years of enjoyment. Fuse it with different burning fuses and create your own magical display!

This is an easy project that can be completed on a Saturday (provided you have all your supplies).

Happy Fourth of July!

Fused Up and Ready to Blow!
