Cost mainly, the bulk of the strength comes from the paper so its better to spend the cash on quality (non recycled) kraft paper than expensive glue.

Use pure virgin kraft paper and a high solids glue for the strongest tube.

Yes but use dextrin as aditional glue.It make hard tubes

It's gypsum or plaster.. The thing you wear on your leg or arm when you break it. The stuff that hardens fast. People use it when decorating home interior... Some call it White magic mud. In my country we call it gips. You can buy this stuff pretty cheap some place where they sell wall paints and cement. Some place for home improvement.

Gypsum

It's gypsum, the thing that docs put in broken arms , pretty cheap and it dries quite fast, in my country u can find it at construction material stores

its actually better to roll them one after another because when you have 2+ sheets of paper being rolled around something, the further you roll the wider it gets so its diameter is bigger with every turn so when you have the 2 sheets rolling in the same turn, the bottom sheet will be trying to match the length of top sheet but cant so it scrunches up leaving air pockets. it basically ruins the tube

@@HomeGrownPyrotechnics thats right bud

@@accipiternisus649 Commercial tube makers vary the paper length and thickness to achieve the desired wall thickness, they never use more than 1 sheet ;) If HGP`s theory was true, rolling with a single sheet of thick paper would result in the top half shearing off as its being rolled ;) The thickest paper i use is for 6lb (1.5" id) motor tubes. The individual sheets are made up of 7 sheets of pure kraft paper 4ft long. This is the method i use to make the sheets. ua-cam.com/video/WBYzVPEmg2Q/v-deo.html

@@colspyro i follow your channel for a long time.Let make video how you make tubes with that roller

@@accipiternisus649 The machine in the link just makes the multilayer kraft sheets. The sheet is gravity fed into a hand cranked, tube rolling machine which takes care of the rest including the tricky first turn. I will upload a vid of the tube rolling machine but it`ll be pretty boring. Here`s a paper alignment/tracking check. The only difference when rolling the tubes is the paper doesnt come back out ;) ua-cam.com/video/mAK0PVqVz2A/v-deo.html The alignment and tracking is correctly set when the machine can endlessly loop a sheet of kraft without any intervention ua-cam.com/video/7XEC6eTC6E8/v-deo.html

I've made some tests and it seems dat 60/40 KClO4/Al sounds better. It have more deeper sound instead of sharp sound

no if you want to do it perfectly you need to take mole weight of potassium perchlorate add it in a paper cup and add mole weight of aluminium
