New 30 shot hybrid rack video

[shrapnel]

Here is the first video, will try to get more up later. The rack is an aluminum/wood hybrid that weighs 6 pounds without tubes, 30 pounds with. it is a 30 shot 10 degree angle, I'v been working on it for a while, testing, abusing, redesigning and here it is, let me know what you think! I have a video of 3 cannisters loaded upside down that did nothing but slip the plugs in the tubes.http://www.pyroreview.com/gallery/data/507/1461ed_boom.WMV

Its alright, i would advise putting more stability on that rack though, it looked as if it was about to tip over.

[Spyder207]

Looks good, but I agree with Chris, I'd add some stabilizers to your base.

At least it was positioned properly so that if it did tip it would shoot toward the sides and not toward the Audience. Schrap, those type racks probably do need to be weighted down with something. I didnt think it moved very much but always better to be safe than sorry.:)

[shrapnel]

To see it in person, that racks not even close to tipping, if someone were concerned, there is a space in the corners for 3/8" rebar to be fed through and into the ground eliminating the possibility. In the world of physics if you try to contain an explosion you are asking for schrapnel, allow something to move and flex with the forces and chances of a blowout are much less likely.

[shrapnel]

Here is a clip of one of the upside down cannisters. This was just for testing, obviously not recommended, just wanted to make sure if someone makes a mistake the rack would do it's job in a controlled environment instead of in front of a crowd, this was the second shell you can see the first tube in the back raised up from the plug slipping, i tested the rack in 2 corners and a center-end with burst charges and was happy with it's performance. By the way the pyrogear mortars were outstanding, not one of them was even disfigured after testing, the tube with the slipped plug was repaired and still in use!http://www.pyroreview.com/gallery/data/500/1461upside_shell_vid.wmv

If adding stabilization is in the future for a rack, I prefer to have a swivel base rather than rebar eyelets. This way you can use the rack on solid surfaces (concrete etc.) too.

Schrapnel your a Pro! I love them. No one is doing consumer racks like this and at such a great price. I look forward to seeing them at the Hales Demo. Bring a bunch of them for I am sure if I don't buy them all the others will. Hey how about doing some with fiberglass?

Thanks for posting them!!

[Dan]

Yeah, I bet these babies would be super light and easy to carry if they were filled with Fiberglass tubes. I think that would be one hot consumer product.

[RudyG]

Schrapnel, I would be interested in them too. It's just what I was looking for.

[shrapnel]

Rudy, I'm gone for the weekend, i'll get in touch early next week to see what you would like or you can pm me.

[Spyder207]

I would also be interested in a rack for the fiberglass tubes if you are making any of those.

[shrapnel]

As I posted on Pyro Review, I will video one side all ten tubes fused to fire as fast as i can to test stability, anyone like to see it tested another way?

[SkiingPyro]

Quick question: Why do you call it a hybrid rack? Is it simply because it uses two different materials, or does it achieve some kind of dual function that I'm missing from the video/explanation?

[shrapnel]

It's as simple as that, when i set out to build my new racks I was looking for portability, something easy to store, light weight, low cost and effective. I spent a while playing with all aluminum like some of the 1.3 racks but could not get the rigidity i wanted and i think most if not all of them are single row racks that must be staked and realized the best i could come up with for my consumer racks was a combination of wood and aluminum. As for storage, these racks are 1'x2' and can easily be stacked 6 high taking up 2 square feet of floor space for 180 tubes! The wood used is not inexpensive pine either, it is a dense hardwood - poplar.

[shrapnel]

I am interested in hearing from those of you who prefer fiberglass over hdpe, is it a regional preference due to availability? In this case the hdpe actually helps to stabilize the rack with it's weight because the rack is so light, with fiberglass it would definately need to be staked. The pyrogear hdpe mortars are priced very competitive with fiberglass and hdpe is becoming an industry standard for a reason, they're the safest. I think that's why the strongest shell on the market, Excalibers (arguably) come with the strongest tube on the market, hdpe. You could easily make one of these for fiberglass, it would have to be resized for the smaller o.d. of fiberglass and staked during use. I am confident fiberglass would hold up to anything on the consumer market just fine.

here is some crappy video of the rack fused to go off 10 tubes all one side in less than 5 sec. in the second shoot only 8 shells lit but the first one all ten went in about 3 sec.

[climber]

Your right "Stability" I'll stick with HDPE.

Thanks, can't wait to see them. You need a name for the racks. Something that refers to the light weight. Like "Sky-Light Racks" or something like that.

And i think, "Light-Flight Racks" would be just fine too. Your ad could start like this,
Get it right, with "Light-Flight" and so on and so on. Many years ago i was in the advertising game.

And if I use that I'll be paying royalties for how long? :D

Schrap,
My man, you know i am easy to get along with. I'm sure we could work something out. I'll save you a copy of the Golden Bear catalog & demo video too, just because i am a nice guy.

Pyro Gear is going to test shoot one of these this weekend, can't wait to hear what they think!:cool:

[noel]

You have PM.

[shrapnel]

Eye candy!!! 240 tubes.

[Aric]

Is someone able to send me a Golden Bear Catalog and demonstration tape because I am interested on their products?


Thanks!

[shrapnel]

Aric, why don't you just call yourself and request one?

[Deweycoon]

Schrapnel, will the racks be sold in a kit form that requires the person that bought the rack to put it together.
It sure would save on the shipping cost.
The rack is bolted together right...I would make it fully assembled and in a kit form and the buyer can decide.

[shrapnel]

Dewey, no. There are no bolts or anything to come loose. The aluminum is riveted and drilled and screwed to the wood which is screwed and glued. The rack would be shipped with tubes ready to fire to cut down on user error. The over all size is about 12"x24" and weighs less than 30 lbs. shipping should not be much more than ordering the tubes alone. Two of these could be shipped in one box and still be under the max. shipping weight! That is a great idea and was considered (shipping in pieces)

[shrapnel]

[Deweycoon]

Oh yes user error, it's best to keep the liability to a minimum.
There are people that have problems with instructions, thats for sure.

[Aric]

Schrapnel,


I requested this information from Golden Bear Fireworks about one month ago!


Perhaps there were no more available? :confused: :confused:

[Dan]

Schrapnel, there is a WAY AROUND the whole liability issue. It is used ALL THE TIME in the ultralight and experimental aircraft industry when selling an aircraft, or other "flying" device.

WHen someone sells them, they dismantle a wing, or unbolt the engine, something very simple, YET effectively rendering the aircraft "unflyable". They then sell the aircraft in "non flying" condition, and as "scrap" It even states this in the "buyers contract" they usually have written up.

Now, you and I both know, that whomever buys it, can simply bolt the engine, wing, etc back onto the craft, and it's ready to go. However, since the aircraft was SOLD as unflyable, and non airtworthy, the selling party, assumes NO LIABILITY for what the buyer does or does not do to get it airworthy.

You could do the same with your aluminum mortar racks, if you wanted to sell them "knocked down" for easier shipping. You basically sell them as "unuseable" mortar rack "pieces"..then include a disclaimer, that this item was sold as unuseable "scrap", and if the buyer chooses to put them together and use them as a mortar rack, they do so at their own discretion. You assume no liability on how they use this pieces you sent them.

Could work for you too

Dan,

It's not the problem of loosing the lawsuit, it's spending $25k on lawyers to win the lawsuit that hurts.

[Fireworkslvr]

The video looks great, and it definately appears that you put some time into the making of that rack. very nice construction!
