Very good video showing mistake and correction. You have made a lot of progress! Thanks for the video.

[weld_dat_fakah]

These look great 👍 I'm glad to see you making video again. Your shells look great! Maybe you could make a video on how to paste the shell so it looks like the commercial ones... or maybe for to improvise the wrapping machine 🤔....
Just a thought.. love your show! God bless from USA 🇺🇸

Great job. I think your hemispheres will be fine and you can make from them outstandind fireworks. The commercial paper hemispheres for 4" have 93mm outside diameter and walls are 4mm thickness.

I can't seem to find an answer anywhere.... What is the paste you use for forming the Kraft paper into shells?

Nowadays you also could just 3D print a mold

[karllaun]

Great tutorial. Do you have to put anything on the plaster mold to keep glue/moisture off of it?

BTW C6 stars usually go into spider shells, they are fast burning stars. For shells like yours, i believe tiger tail stars are better.

Helo bạn có thể cho tôi xin công thức làm hạt star được không thank you!

[madsfleetwood]

I have to ask what do you see for paper and glue and where do you get it

[gianco]

But i have to dry the hemis on the plaster?

[radzzlumabong]

What's the name of the dement you use?

[jamisonlm]

Am I the only one that thinks the uncut hemispheres look like little hats?

it might be worth your time to buy a 3d printer. you can 3d print 2 inch ball shells for $0.12 USD per set. You can also 3d print the mold to press your hemis. Ive pressed hundreds with no signs of wear.
