Absolutely, card mortars are fairly common in professional displays for use with shells, I've got 12 racks of them I use for exactly that. There's always a debate on whether card or fibreglass is better, I personally believe card is stronger, if heavier and in need of extra waterproofing. The Essex winding ones are spec'd as mortar tubes with bung pre installed etc. Best of luck!

Awesome, can you reccomend me the wall thickness and height for the paper mortar tubes? i asked for a quote of 8mm wall 3inch id and 15inch length(height).. do you think the wall is too thin? if so please let me know how thick a good paper mortar wall should be. thanks alot 

There's always my site too for grp if needed :-)

wow cool website man the mortar tubes arent that expencive either i was expecting grp to be around 10-15 each.. but then again last time i bought a mortar tube was about 4 years ago. and you have a ton of chemz on their too which is awesome! 

-edit- gah hit post accidentally meant to say thanks!

Thanks James! do you know if the card based tubes would be suitable for a shell launch aswel? Will have a look at some of those others too! thanks again

i have ordered chems from ebay a couple of times and then found someone who sent me an item list with prices, i used this person for about 3 or 4 years afterwards and then stopped making fireworks because of health issues unrelated to fireworks haha but for anyone reading this and doesnt really know where to get some chems for the first time buys then just have a browse on ebay for something minor like potassium nitrate or maybe even aluminum powders then before you buy it just send the seller a message asking if he has any other chems for sale and to get an item list good luck hunting!
