Thanks for your encouragement.
The stainless is supported from underneath along its full length with the angle iron, square section and plate sub-assembly shown. The stainless is pulled down onto that sub-assembly repeatedly along its length(on average one stainless bolt every 200mm).
Both x axis and y axis rails are constructed the same way.
Any stainless tube / mild steel expansion differential will be accommodated without weakening the assembly. Welding / glueing can occur throughout the sub-assembly with the exception of where the stainless tube is bolted down onto the mild steel sub-assembly.
Looking forward to you and Nigel having a looksee.
