Right, after finding out on this forum how hard it is to get welding/brazing gas in the UK, I've decided to switch to "plan B". Would it be possible to glue steel tubes into lugs using the sort of epoxy used for carbon fibre composites? I seem to recall hearing about aluminium tubing being used to build frames in this way before the advent of TIG welding. I can't think of any reason why it wouldn't work with steel as well (providing I'm not misremembering something), but I have a history of thinking things will work when actually there's a glaringly obvious reason why they won't, so I figured a second opinion would be useful.
Thanks in advance
