Solid

You can make RBS beam from cutting 1/2" sheet with a laser cutter.

Hollow

You can make hollow square beams 1"x1" beams or 2"x2" beams from thin plywood sheet. Just cut long thin, dovetail-edged strips, 1" or 2" wide and glue them together.

Dexion Speedframe

This is a high-strength shelving system made from cheap steel square tubes and unimportant but elegant interconnectors.

The tubes are a lovely 1" (25.4mm) square x 10 ft (3048mm aka '3m') long.

  • Speedframe (1" square x 3048mm long) x 1 length

£20.00 per 3m length http://www.tradesystems.co.uk/acatalog/Dexion-SpeedFrame-25mm-Square-Tube-System.html?gclid=CO20puGvvJ4CFQQMDQodVCn5Cg

  • Buy Used! Shelving outlives many a business plan, so check your telephone directory under 'shelving/racking'.

You may get lucky, and pay £10/3m rather than £20/3m. http://shop.instant-shop.com/stodec/category740226.html

Wood

Warning

In North America, wood which is called '1x1' or '2x2' is actually smaller than 1 inch or 2 inches in cross section. This is unfortunate but legal. Speak to a lumber yard or other supplier about getting 'wood which is actually sized 1 inch by 1 inch or 2 inches by 2 inches'. They will be able to help you, possibly by setting up a small order correctly sized material with a local mill, which may be a quick job. (If you are a woodworker, this paragraph is obvious, and we apologize. And you have a table saw.)

Imperial

  • 1"x1" or 2"x2"

Metric

18mm x 18mm or 44mm x 44mm (Metric)

Construction Debris

It's plausible that we can use Eiffel or similar to mill construction debris wood down to 1"x1".

Notes

  • Nails - After checking carefully with a nail finder.
  • Grit - Use a stiff plastic brush to clean off your wood. Stone pebbles will chip your saw blade.

Working Notes, ignore below this line

  • Eiffel should be able to drill the beams for daughter machines.
