This week has been a bit busy on other things but I did manage to finish the upper patch....

I removed the top of the birdcage bow to get access to the welds for the T-Top longitudinal frame piece thingy. The bow has been acting as a collector for an awful lot of rust flakes - not surprising that there were so many holes.....

Next: to complete the lower patch which attaches to the underside of the birdcage bow...

... and then try it out for a welding dummy run although I probably won't use these weld clamps as the join is curved and the clamp is straight so the clamp pushes the pieces of metal further apart than they should.

It all seems to be going together ok at the moment (famous last words) so the next job is to unpick the spot welds on the birdcage bow and construct a new section to replace the rusty bit..... A 700mm square of 2mm steel arrived earlier this week so I think I have everything required to do this.
I also need to start thinking about how this all goes back together as the positioning and sequencing of the puddle welds is going to be important as I don't want to do any welding up side down....(is it even possible?)
