dangerousamateur Posted November 16, 2019 Share Posted November 16, 2019 Hi guys, I've got a large stash of tubes that was cut obviously with a not so sharp cutting device. All tubes have serious ridges at their ends, what impedes entry of tools. Now I'm locking for a suitable tool to fix that... Any ideas for the perfect solution?

Arthur Posted November 17, 2019 Share Posted November 17, 2019 Paper tubes can be gently opened a little with the taper of a plastic funnel, if you can find one the right size. Link to comment Share on other sites More sharing options...
memo Posted November 17, 2019 Share Posted November 17, 2019 if you have a moto tool use the sanding drum to lightly take the edges of. or get a tube cutter.... i use a saw and always have a burr Link to comment Share on other sites More sharing options...
davidh Posted November 17, 2019 Share Posted November 17, 2019 It shouldn't matter. Stick a smaller drift into the tube and twirl it around the give a little relief for your tooling. It's just pyro. Your going to burn it up or blow it up anyway. Link to comment Share on other sites More sharing options...
justvisiting Posted November 18, 2019 Share Posted November 18, 2019 Nooooo! That's like saying it doesn't matter if your gal looks good or not, she gonna leave you anyway For NEPT tubes, I use a rolled up piece of sanding cloth like plumbers use, and twirl it in the end.

Purdy I promise that if you're making hundreds of farfalle or tourbillions or drivers or Tultepec style rockets, at some point before you are finished you will quit caring about how the tube looks!

dangerousamateur Posted November 18, 2019 Author Share Posted November 18, 2019 (edited) You're right, it's just pyro, but I really prefer smooth ends for ease of further work. I thought maybe anyone here had a "perfect solution" for this. Using a stepped hole cutter might do the job, and since it's paper a cheapo chinese one might be up to the job. Few seconds for each tube, if it works that is. Edited November 18, 2019 by dangerousamateur Link to comment Share on other sites More sharing options...
NeighborJ Posted November 18, 2019 Share Posted November 18, 2019 I put the tube in a tube support just before puting it on the spindle and jam a rammer in each end and roll it around to crush the burr out of the way. Even the factory cut ends have a lip that needs opened up a bit for the tools to pass free. Link to comment Share on other sites More sharing options...
BetICouldMake1 Posted November 19, 2019 Share Posted November 19, 2019 Sand paper or even a file can knock off any "fuzzies" that bother you. A plumb bob, funnel, or similar conical device works well for flaring the ends if necessary. If you want to be real fancy I believe caleb sells tool for doing that as well.

dangerousamateur Posted November 24, 2019 Author Share Posted November 24, 2019 These are not fuzzies but rather resilient, hard bulges, hard to explain... A tube reamer wont do the job. I wish a had a lathe Link to comment Share on other sites More sharing options...
