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.

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!

Done!

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!

50-shot spectacular!

        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.)
