If you can afford drinks to get bottles to make your rockets, you should be able to buy some tornado tubes. If you can't afford those, how can you afford PL Premium? Water rockets are super inexpensive, so if your budget is that limited it is probably because you are splitting your resources among several hobbies. You may have to set priorities. Good luck!Water Rocket Expert wrote:Key words are "for me."

Re: Boring out Tornado Tubes
I know maybe I'll buy some but the reviews are bad and they seem to leak and crack.

Ever heard of rubber washers? For me that prevents them from over tightening and cracking.Water Rocket Expert wrote:I know maybe I'll buy some but the reviews are bad and they seem to leak and crack.

Re: Boring out Tornado Tubes
Hello All,
When it comes to widening Tornado tubes we use a Drill Press and a step drill piece. It works a treat, and you can then sand away the inside for a 18 mm internal diameter:
1) Above shows the older Tornado Tubes we used a while ago, these had a ~16mm internal diameter, but it also shows the Step Drill piece.
2) These are our present couplings using the same principle to widen them- except they have been sanded a bit more to give an 18mm internal diameter.
Hope that help!

The step drill idea looks like it really works great. That looks like a good tool to have in your toolbox. Thanks for sharing the pictures.

Re: Boring out Tornado Tubes
Since the bit only needs to drill plastic, you can probably get away with buying a cheap one. It won't need to be titanium or super hardened.bugwubber wrote:Hmm, another $30 tool to add to my things to buy list. Looks like it's worth it though.Team Seneca wrote:That's what I'm talkin' about!

Re: Boring out Tornado Tubes
I bought a step bit from Harbor Freight today. I plan on trying your method for boring the tornado tubes. It cost like $5
