Steering columns
« on: 31 October 2021, 09:34:04 pm »
Hi,

As I get deeper I to the detail of a build I'm starting to bump up against a load of things that I can't find an obvious answer to in the files, (unless I've missed it).

First unknown is safety related, I have a detachable steering column boss which needs a 3/4" or 19mm steering column. Logic tells me that 1.5mm wall tube is the thing to ho for over solid rod. It's lighter, but is it safe? I think so, but I've never built a kart before!

Thanks,

Peter

Hi Peter, I use tube on my steering columns to keep weight down. On the CK i used 20mm conduit because I had some.

Thanks Jim, when they delivered the rear axle it became apparent how heavy solid  bar is!  so tube seemed the logical route  and I wasn't aware of any massive forces acting on the column, but always best to check first.

Formula Ford always used 1.6 mm tube, usually 19mm/ 3/4" so I reckon plenty for a CK!
