Agreed, but AFAIK aluminium isn't all that strong (unless you start talking about complex honeycomb structures and so on). On the same note, has anyone ever made a buggy from copper plumbing pipe? I reckon that 22mm pipe should be reasonably strong, and there are plenty of angles and joining type bits available to weld/braze together. After all, if someone can manage to build a buggy from PVC waste pipe (surely that must bend and flex an awful lot?) (as seen on a web page, sorry can't remember where), then copper pipe has to be worth a shot. -- Phil Dye | E-mail: pmd@tcp.net.uk Network Manager | Tel: +44 (0)1703 393392 Total Connectivity Providers Ltd | Consider myself properly disclaimed "To stop milk from turning sour, keep it in the cow" = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = From: mgibson@madge.com (Martin Gibson) Subject: Re: Aluminum for buggy's Date: Tue, 25 Jun 1996 07:19:05 -1000 Organization: Madge Networks Message-ID: <4qp759$deg@madge2.dev.madge.com> Phil Dye wrote: >Agreed, but AFAIK aluminium isn't all that strong (unless you start talking >about complex honeycomb structures and so on). Aluminium isn't very strong. Aluminium alloys can be; you can build a lighter buggy with the same stiffness using aluminium alloys than you can with steel. If you want to go the whole hog, use carbon composite tubing... Look at what the bike market is doing; steel is cheap, easy to produce, but heavy. Aluminium alloys are lighter, more difficult to work, and more expensive. Carbon fibre is lighter, stiffer, and a nightmare to work with.
