50-Shot Fanned Mortar Tube Rack
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
- Screws:- 3, 2 and 1-inch lengths
- Power drill
- Liquid Nails -glue
- 50 12 inch x 1.91 ID Polypipe PE4710 tubes, available at plumbing stores. These MUST be polypipe, do not use PVC. PVC can shatter causing dangerous shrapnel. In the firework world, these are known as DR11.
- 50 wooden tube plugs (1.91 ID)
- Fuses (optional)
- 3 2x3x8 framing studs, (total of 5-2x3 at 2 ft long each)(10- 2x3 at 1ft long each)
- 20 1x4's at 27 inches long each
- 2 1x4's at 20 inches long each
- 2 1x4's at 25 inches long each
Wood for the rack
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.
Building Your Racks
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.
Completed 10-Shot Rack
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!
Almost Put Together
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!

Sadly we didn't make those or know how. We get the mortar rounds from Phantom fireworks. Hope that helps. Find a local firework dealer. :)

John- DR 11 tubes are used for 1.75" consumer reloadable mortar ball shells and cylinder shells.
They are available from your local consumer fieroweks retailer.
If you are shooting them 50 at a time you may like to find a wholesaler.

Just curious about what you put in the tubes and how, and where to get the stuff? Not trying to sound stupid, just covering all the bases! Thanks "you rock" great job!

Interesting, but where we live, ALL fireworks are illegal, even the "safe and sane" variety.
We aren't even supposed to use sparklers. The only fireworks we get to see are the professionally set ones sponsored by cities or festivals.
(Naturally, there are a good number of folks who don't think the law should apply to them, and we see fireworks popping off around us anyway.)
