Building an observatory. Construction #14

The steel for my rolling roof finally arrived this week: sixteen three metre lengths of 25mm square section tube with a 2.5mm wall. The wait has allowed me to change the roof design several times 😀

This morning I wrote a cutting list and this afternoon set to with the cut-off saw, reducing all but four of the sixteen lengths to correctly-sized pieces ready for welding.

I do still have a few cuts to make, mostly where I’d like to get the main structure assembled to allow me to cut the extra pieces to fit. The remainder are the horizontal braces for the “rafters” which need a 30 degree cut on the end. My cut-off saw won’t do that without some modification. I’ll work that out this week or decide that it’s just easier to put a metal-cutting blade in the angle grinder and cut them that way.
