Sub 1 mm Paper Tubing

**Gil** · #1 05-30-2008, 10:46 PM

Hi All,

The following happened on the way to a tutorial on built-up ribs. It's around 0.75 mm in diameter and wasn't too difficult to do. I'm pretty happy that it turned out this way as doing scale chrome-moly tubing in paper was looking pretty dismal till now...,

Any guesses as to how it was done?

Wet tracing paper?
0.75 paper cut .075 wide and chamfered the corners? However its done, it is impressive

What has amazed me is that it says RULER on your steel rule. My metalwork tutor would have a fit if he saw that!

Kaz,

Mine too. It's made in China, so considering, they've come a long ways but some things still make it through.

No to wet tracing paper. It's plane card stock and not chamfered. It is actually rolled..., But something that's used in a specific category of metal working was used to get the roll...,

This I want to learn, eventually.

Meanwhile, my first guess would have been spaghetti (which is kind of papery, right?). I've been thinking of wetting down, or boiling, thin spaghetti stripes to the point when they are pliable, then bend & cut them to the shapes required, paint them, and glue them onto the paper parts where they belong.

I know they won't hold up as a structure by themselves, but glued to paper they would make quite at good impression of tubular steel, I thought.

Hi Leif,

No it's not spaghetti. Again, it's regular colored card stock. No water nor mandrel was used in forming it.

This may prove to be one of the more difficult methods to figure out. I'll give a hint, "the curve must be started before further forming is accomplished...,

The end result was hardened with Cyano Acrylate glue though....,

Nearest I can get

Start roll wind as tight as possible unroll cut to width reroll

I cheated on the paper thickness ............ hey ho !

Yours is brilliant

I have no idea, but am eager to find out how you did it, Gil.

Rolling paper tubes is a skill that I have yet to master.

I don't know how it is done with cardstock without it falling apart (maximum bend radius exceeded). A sheet metal process perhaps? The result is very impressive.

I await enlightenment

I'm thinking you lay the stock in a long v groove thingy then take a long steel spatula like thing and press it into that v groove? After the card stock had a starting curl of course?

C'mon, Gil, you're toying with us!

Give it up, man!
