Homemade Fireworks Shell Wrapping Machine
Here is a my homemade firework shell wrapping machine.
A 12 volt computer power supply is used for the power source. I removed all the excess wires that were not needed and ony used the 12 volt outputs on the power supply. The motor that is used to turn the tape dispenser was purchased from Surplus Center. It is a 12 volt 500 rpm right angle gear motor that is used to power adjustable car seats. An adapter had to be machined to convert the 4mm square output of the gearmotor to accept the gear that is used to spin the assembly. The motor that slowly rotates the shell is a 12 volt 3.5 rpm gearmotor purchased from Amazon. The lazy susan bearing is a 200mm aluminum bearing purchased from amazon. This bearing works 100 times better than the stamped steel lazy susan bearing of the same size. The ring gear is from a Briggs and Stratton flywheel/starter assembly. This can be purchased from Amazon or Ebay. The sponge/water holder is a 4oz metal tin container from ebay. The revolution counter was purchased from Surplus Center along with a small micro switch. The motor speeds are controlled by two separate 12 volt pulse width modulation controllers from Amazon. The shell clamping "C-Clamp" uses a small 1.125' OD X .5" ID roller bearing. A bearing is needed to allow the c-clamp to rotate freely while the shell is clamped securely. The bearing was purchased from Mcmaster-Carr. The rotating shaft is 1/2"-20 thread rod. Two 9/16" hole saws are used to hold the shell and both are threaded on both ends of the shafts. A 1/2"flanged bearing is used to support the small gearmotor shaft. Without this beain the c-clamp assembly has a lot of flex. The support helped to secure it. A 1/2"-20 coupling nut is used to complete the assembly. The machine uses 1/2" wide gummed paper tape. Using a half width of tape overlap gives a even distribution of tape around the shell. I am using 60 revolutions to tape a 3" shell.
The estimated build cost is as follows:
500 RPM Motor $17
3.5 RMP Motor $12
200mm Bearing $18
9/16 hole saws $4 each
1/2-20 threaded rod $6
1.125" ball bearing $7
Briggs and Stratton Flywheel/starter Gear $22
Metal Tin container $4
Flanged Bearing $1
Revolution Counter $5
PWM Controllers $12ea
12 volt switch $2
Hardware $10
Computer Power Supply - Free
Steel frame Tubing - Free
Total = $136

Dude that is spectacular!!!
That is badass brotha. You should market these. Alot of diy pyros would love this
Adding a burnish run will flatten the edges down and give you a nice smooth finish ;) Gummed paper tape benefits from a little dwell time to soften it up and make it more pliable.
Awesome!!!
complimenti molto bella ed eficcente .......sino a calibro i gusci
That's awesome I need 10 of these

That makes 1360$
Yes the C-clamp bearing
Nice
Nicee!
Also what is the angle of the fixture holding the firework vs the tape?
Can you show us how to make one please
Hello, great device. I want to collect the same one for myself. Have you upgraded anything? How long does a large bearing last?
good

Can u give more info or better pics of the c- clap I have the bottom section done but I can't see how the C clamps done due to the power supply in the way
you did a great job! iam a fabricator by trade and when i seen this i thought, how in the heck can a wasp cost 2500 dollars!

What are the black rollers that the tape runs thru and where did you get them? I have most of the stuff to build but just need a few more things. What is the bearing on the nd of the bottom shaft? The one that hooks to the all thread?

The black pieces are 3d printed tape guides. You just need something to guide the tape. The bearing is a 1.125" od x .5" id roller bearing from mcmaster carr.
Where can I find the guide rollers used on the tape dispenser? The black and the white ones. Almost have all my parts
@fireworks1727

The white rollers are just nylon round stock that was cut to size. The black tape guides were pieces I 3D printed. You can come up with anything that you can use that will allow the tape to pass through it.
Flywheel works great almost done but I can not figure out the lower bearing I looked up the one listed but not sure how to make it work any help needed please

What is the ball fixture angle to the deck
@fireworks1727

Its adjustable. The c clamp assembly pivots on a bolt on the center axis. You need to have the height and the angle set correct or your open poles will be large. The shell needs to sit as high as you can get it so the tape goes around the center of the shell and not offset.
What gear is on the angle motor and how was it adapted to the square output

Make an adapter for the one that came with the ring gear from the motor. Or buy a gear. Boston gear manufacturer. The numbers on the box are 09746 and nd12b. Its a steel spur gear. U need to get a 4mm keyed shaft to go into the motor and tack weld it to whatever your going to use for the gear shaft. I used a 1/2" bolt.

It is a flimsy sheet metal backet. You need to make one out of thicker material. The mounting screw holes are metric i think.
How much money for a set up like that?

I don't understand the bearing on the bottom of the fixture that allows the ball to rotate.

Think of that whole c clamp assembly as a regular c-clamp you would use for anything you would need to clamp...if you used a regular c clamp the shell would not rotate because one end is a fixed pad. This is the reason you need a bearing on the opposite end of the motor. As the motor turns the other end also needs to turn. So how i made the bearing assembly. Take a 1.5" long 1/2-20 bolt and machine off the head until there is only about 1/8" of the head left. Take the bearing and put it on the bolt and then put a nut on the bolt. Sandwich everything together. Tighten as tight as you can. Now take a piece of 1.5" solid aluminium rod about 1.5" long and bore a hole in it the o.d. of the bearing and the depth of the bearing width plus the 1/8" depth of the bolt head plus a little more clearance. Proably need about 5/8" or so on the total depth. On the other end drill and tap that side to 1/2-20 thread. Once you got all that done. ..press the bearing into the hole. You sould have a aluminium rod in one hand and you should be able to spin the bolt with the other hand. Screw the hole saw on that bolt and then on the other end a short piece of threaded rod 1/2-20. You and then screw the whole bearing assembly onto the other side of the c-clamp assembly.
Or even make a video on how one is built

Someone commented on 400 for machine well check out the wasp for about 2500 and does the same thing

jimmy tiler ..i don't know what your calling a drive wheel but the motor that drives the taper dispenser is a 500 rpm motor and the motor that spins the shell is a 3.5 rpm motor. Read the description it has the details. Both rpms are adjustable.

Don't understand your comment. I put about 150$ worth of parts in the machine. Obviously I didn't count the cost of things u had laying around like the power supply and steel tubing.
