Profile storage tubes

We all know the cardboard tubes made to keep or mail rolls of plans. Some suppliers also use them to ship materials into long sections that could bend easily. But, once arrived in our workshop, where do we store these profiles?

First possible answer: in tubes with caps, made of translucent plastic to see the inside. Available in pack of five for a reasonable and decreasing price. Their diameter may, however, be somewhat small. It takes a lot to store many different profile references.

The same supplier also offers square section tubes that allow a more compact storage. They are however much more expensive and delivered without caps. It will be seen below that it is nevertheless possible to find caps at another supplier.

A Do It Yourself solution

This solution aims to use materials that are easily found next to your home, and if possible cheaper than the products seen above. As much say it right away, for the price, it is not done! The tube is inexpensive, it’s the electricians’ one, called IRL, which means Insulated Rigid Light (ex IRO for the ancients). The most useful (outer) diameters seem to be 20 and 25 mm. In the most widely known DIY stores, the 2 to 2.4 m long tube costs from 0.75 to 0.80 € in 20 mm diameter and 1.35 to 1.85 € in 25 mm diameter. Of course, it’s even cheaper in batches.

In a 2 m tube, four 50 cm storage tubes can be made, each costing approximately 20 to 35 eurocents depending on the diameter. It remains to find the caps that will fit. Or you can just tape one end, or even plug with a pellet of paper! But it's not very classy nor very safe…

Caps

There are two leads of search:

Bottle corks

Bottle replacement corks can be found in general stores for a moderate price. By experience, those equipped with a plastic capsule fit well on the ø 20 tubes, but break down quite easily. On the other hand, for the ø 25 tubes, no conventional stop is suitable (to my knowledge): the wine bottle cork — whether actual cork or synthetic — is a little too small, and does not hold. As for the champagne cork, it is way too big!

Furniture leg caps

Furniture leg caps are available in many diameters, and in two types: either internal, with an external diameter substantially equal to that of the tube, or external. For our application, I see a mixed use: an internal cap for a definitively closed end, and an external one, easier to remove, for the other end.

We see that the price of these caps has a very negative effect on the overall cost of our storage tubes. The interest remains to be able to choose the diameter and the length that suits our needs best.

Another source of caps for metal tubes

Here, it is no longer a question of finding next to one's home, but on the Internet. A dealer specializing in metallurgical products offers caps for tubes of round, square and even rectangular cross-section, in many dimensions, and considerably cheaper than in DIY stores. However, the shipping costs must be considered here. This will be interesting, for example, when ordering steel sheets or profiles - which I did when I bought stub to improve some tools (vise, drill stand).

Caps for metal tubes

There is also this other supplier, even cheaper, but apparently with disproportionate fees. I have not tested yet.

Examples

Here is first a ø 20 tube, 40 cm long, one end with internal cap, the other with cork stopper. Perfect for storing Evergreen polystyrene profiles.

20 mm diameter tube

Then, a ø 25 tube, 50 cm long, one end with internal cap, like the previous one, the other with an external cap. Rather suitable for metal profiles or tubes: piano string, nickel silver, brass.

25 mm diameter tube

These tubes are stored in a drawer (originally designed for kitchen elements of a well-known Swedish brand). They are kept superimposed in a kind of rack made with sections of salvage tubes, fixed by a screw passing through the bottom of the drawer.
