#88181 UKPS 2017 AGM!

Posted by BlackCat on 07 May 2017 - 08:22 AM

I can only echo the sentiments of those above, it was a really good day and I also feel that there were some really good ideas for taking the Society forward. It was really good to meet you all and I hope to see you again in the future, not too distant though!

 

The fireworks were awesome! Thanks guys!




#88177 UKPS 2017 AGM!

Excellent day. Special mention for Rob L for organizing the food & Karl for a great display.

 

Been pretty despondent about UKPS lately, but this was a great AGM - lots of enthusiasm and great ideas. Hopefully a chance for us to put recent petty squabbles behind us and start building up the society agaiin.

 

Was great to see new faces as well as some familiar ones...




#88178 UKPS 2017 AGM!

Posted by Karl Mitchell-Shead on 07 May 2017 - 12:20 AM

I had a great afternoon too, it wasn't a huge turnout but those that attended were just the right people and it was a real pleasure. I feel UKPS has turned a corner and the discussion about where we as a community are going to start heading was extremely productive.

Steve - the award for best explosives infovideo goes to you and Billy Bass - 10/10!!

Glad you all enjoyed the display - the triple peanuts were nice!

Here's to the future :)


#87787 A&K Application problems review...

Posted by BlackCat on 08 December 2016 - 04:12 PM

Since posting the above, I've had a further E-mail from Andi Jamieson, who is the ELO for Northants, and copied to the enquiry officer handling my application. In it, he says that having seen my E-mail responding to their E-mail copied in my previous post and having a look at the updated UKPS Good Practice Guide via the link that I sent them, he now believes that the Police are responsible for issuing licences for pyrotechnics. Consequently, he's advised my case officer to go ahead and issue me with an appropriate certificate.

 

It seems that re-sending them the link to the GPG has done the trick and broken the stalemate so is, perhaps, something that future applicants should include with their application covering letter.

 

I'm not going to celebrate until I have the piece of paper in my hand but, a big thanks to all of you that posted advice and support for my endeavours and a special thanks to Wayne.

 

I'll let you know when it arrives.

Absolutely, it would be great to be involved.  I'll be in touch once I know more.

 

Also, just for every bodies reference, I've updated the good practise guidance to include UN MAN2 in explosive certificate applications:

I was recently sent this, not a great fan of pyro 'musicals' but this seemed pretty impressive. Particularly impressed with the flame bursts.

 




#79848 Black powder VS Flash powder

Posted by Deano 1 on 10 May 2013 - 09:31 PM

hi m8,,why dont u make some 3/4"id rammed black powder(75/15/10) thunderflashes...i did unintentionally when i started trying to make rockets... and you dont need a ball mill.the kn03 is ground to talc in a mp,the sulphur will just need the lumps kneaded out if its pyro grade i do this on a small sheet of plastic with a teaspoon and you will need airfloat charcoal,,i think it was vine i had then...now for the tooling...lol u will need,,,a 1" thick pice of wood,,4"sq is fine,, a 6" nail and a 3/4 piece of round dowel 7"long with a hole drilled 5.5" deep thru the centre the same dia as the nail and another length with no hole....i mix my bp shaking in a coffee can untill my arms are sore,,you will want to put tape round the lid so you can do this indoors without any dramas you can then open it outside to disloge all the powder trapped in gaps without making a mess....hammer the nail thru the centre of the wood,,by the time your doing this your 3/4 id 7" long cardboard pyro tubes will have arrived,,, place 1 over the top of the nail and centre then pour a teaspoon of bp in(a paper funnel is a must) insert the hollow rammer over the nail, slide down and bed firmly in the powder now your redy to ram (if you dont have a soft mallet pad a hammer with rags untill u do) 4 or five sharp smacks will do,you will feel the bp compressing with the first few hits,repeat this process untill your above the nail then switch to the solid rammer untill ur 1/4" from the top then twist off the nail and there you have it,,,now you may want to have another nail sawn in half so you can make smaller ones..a piece of visco is inserted well into the core taped up and the other end plugged..the 7" one will have 35g+ of rammed green meal and will make a lovely thump but halfsize is more doable in the garden...to give you an idea about flash,,,3g with a light confinement will be louder than the 7" bp thunderflash but its a sharp bamg not a lovely round thump and the smell of bp...aaahhhhhhh...u can also ram foutain compositions in ur tubes

Was ya pi553d when ya typed this lot up dude :lol:




#79123 2013 AGM Announced

Posted by Guest on 26 January 2013 - 02:46 PM

Just a request but could the agm do some more hands on practical demonstrations, we have the 100g rule. let use it to our advantage.

 

we come to forum to learn safely a hobby we all enjoy. all could be done within 100g rule

 

star rolling

Comet making (using Resorcinol Resin so they dry within 10 min)

BP competition ( bring 10g of your best bp and have it tested and timed to other competitors)

Charcoal making demonstrations

Maybe vic could make a 100g rockets being made and tested.

 

All we would need is a small marquee.

#78135 Over inflated prices

Posted by phildunford on 25 October 2012 - 08:58 PM

As long as there is no simple way to prove your bona-fide to a retailer there will always be a premium on easy to buy fuse.

It seems that you have to be 'in the club' to buy fuse from a firework company, and it's not an easy club to join...

I've mentioned before that I would like to see UKPS membership as at least a nod in the right direction of proving good intent. Any retailers out there willing to get involved, please message me.

As to any individual providing a service it's caveat emptor (more Latin!) and if you don't like the price you dont have to buy it.

Keep calm and carry on chaps!

#88909 Proposed EU ban on Potassium Chlorate/Perchlorate for members of the public

Posted by BlackCat on 25 September 2018 - 06:08 PM

Like Arthur, I have been aware that continental webshops have added a statement to their websites regarding compliance with the EU directives on potassium perchlorate and potassium chlorate, however, I have not seen the same attached to ammonium perchlorate. I was also under the impression that the introduction of the EPPP was instead of UK compliance with these directives.

 

As far as how other countries are coping, I'm sure we all know that the Maltese have a very long tradition of celebrating saint's days with fireworks and that a good pro[portion of those set off are made by amateurs in firework clubs. I don't have any contacts over there but, somebody in the society might and, if so, it could be a good place to get a view. Mind you, I guess that any opt-out would require the countries government to get on side and negotiate on behalf of the interested parties. Call me cynical if you like but I can't see any of the UK parties wanting to do the right thing by us!




#88424 16" Shell of Shells The build and the shooting.

Posted by Arthur Brown on 27 September 2017 - 01:33 AM

After several years nurturing a friendship, an invitation was made available to me privately, to go o the USA, to a site licensed by BATFE and the local authorities there,  and build a shell!

 

This was something special of an invitation so it had to be something special of a product. PLUS I had to travel there totally inert, and return by air totally inert too. BUT ingredients could be ordered to be delivered at the site.

 

Here is the video, This is what a Brit did under a BATFE licence in the USA.

 

 

This was my first attempt at a shell! But a lot of design effort went into it. Probably 100 people from the USA were making things under the licence, some were recognised as being good builders and one UK builder made his mark.

 

I'm in a truckstop  on the way to LAX at the moment, so may not reply for some days.

 

I'll continue writing up the build with a couple of pictures from home, maybe next week. 

 

NO I will NOT share the invitation unless I know you well. No I will not advise you what to do. A 16" shell may be above 100gNEQ -I could barely carry that shell.

 

To all the ELO's watching, enjoy! It's pretty and it was all lawful in the BATFE licensed place. I have the skill to do it but the wisdom to NOT do it in the UK! I have to get through US and UK border protection yet!

 




#87587 Rocket tool sketcher

Posted by JamesB on 12 September 2016 - 11:29 AM

All working now, thanks again Vic,

 

I've got some 15mm Aluminium bar stock ordered and a design for 15mm ID stinger style rockets (I've got an abundance of 15mm tubes and always fancied trying the stinger design). I'll put some photos up as this progresses.




#81983 Smoke ring over Leamington Spa

Whoever it was was GOOD a nice round stable ring for long enough for someone to photograph it. If it wasn't one of us then there is a potential new member there!




#81013 Petrol Fireball Eeffects

Posted by bangkokpyro on 09 January 2014 - 10:58 AM

This is a good way to make a big loud and hot fireball that produces a great smoke ring every time.

 

Use a 3 or 4 inch mortar tube (fiberglass works fine for 3 and 4 inch, make sure first it is leakproof) Fill the first 2 inches with water then  fill to within 2 inches of the top of the tube with a mix of Petrol and Diesel  85/15 or 80/20 works just fine.

For lift charge approx 60 gms of 2FA for a 4 inch and 45gms for a 3 inch is placed in a double plastic bag along with 2 e matches ( test to make sure the e matches are good ).

Twist the neck of the bag around a few times and bend it over against the sides of the bag. Now wrap tightly with some good quality black PVC electrical tape. First cover the bag surface in one direction then again at right angles to the first wrap so none of the plastic bag is visible and it has 2 layers of tape all over. You now have a ball of B.P with 2 matches poking out. You don't need more tape the B.P does not need to be confined well to work

 

The bag can be placed into the mortar up to an hour before firing.....Putting the 2 inches of water in the mortar first ensures the tape is not softened by the Petrol/Diesel mix. Give yourself a good 30 foot of scabwire to connect to your firing device....you don't want to next to this if it goes off unexpectedly !

2 matches ensure ignition.....it's no fun having to empty out the mortar if it fails to fire.

2 inches of water and 2 inches empty at the top of the tube will ensure no petrol ends up burning on the ground.

If you're worried about the mix not igniting add a pinch of Titanium to the B.P.

#77753 Flash Powder Info

Posted by bangkokpyro on 17 September 2012 - 12:27 PM

I have to say that the diference between 33.3/66.6% FP and 70/30 is negliable and both are as sensative realistically.

Mgal Is more sensative and powefull as it has sharper edges than ali (like for like particle sizes) so swapping to ali would be better yep.

Bangs are part of the display but JUST bangs are just a recipie for trouble :-(


My God! talk about massacring the English language. :)

Mg/Al is not more sensitive and powerful than Aluminium because it has sharp edges. It is more sensitive because it is an alloy containing 50% Magnesium which is more sensitive than plain Aluminium.
Aluminiums used in flash powder are generally flake shaped particles and as such are not sharp unlike granular material. It is the large surface are of the particles that give it it's sensitivity.

Olly.
Is flash powder a 'high explosive ? No and as such does not detonate but this is academic really as even a few grams of any kind of flash will in the right circumstances remove your fingers with ease;
Just a hundred grams will kill you if ignited in an unconfined pile in front of you. No flash powder is safe. 70/30 Perchlorate and Aluminium is probably the 'least dangerous' and exotic mixtures containing
Magnesium, Sulphur, Permanganate, Antimony etc will one day lead you to disaster.

Making bangs is a small part of pyrotechnics and perhaps the easiest way to get hurt or bring unwanted attention to yourself. Far more gratifying and difficult is being able to make other devices
such as fountains wheels, shells, mines etc to a high standard.
My advise would be that if you have to ask the kind of questions that you did in your post you should not be even thinking about making flash powder.
Get some books or look up some information on the internet before you attempt anything else. When you can make a 'hot' Black Powder and put it to use in various devices then maybe
you would be ready to use flash powder wisely in a crossette shell or as a booster in a small shells etc.
A good place to find some safe reliable information would be somewhere like skylighter.com which has a wealth of step by step articles on how to make a multitude of devices safely.

Posted by Night Owl on 01 January 2012 - 10:58 PM

I thinks its more the fact he has run that company for 47 years, show me any companies accident book of 47 years and will they be able to say there has been NO accidents? I doubt it, If a younger company slates this accident rate of a 47 y/o company then that is very foolish in my opinion and jus invites karma to bite you on the A**
