Big Brands Downsizing to 3m x 2m build

Looking good, may as well weld the "pretty chunky steels for the main rails" after all, cant see them moving shape any more than they already have from the bed cross sections...

Good to see your sorting her out tho, thanks for sharing!

Im not too sure they are well fixed down to the base with m20 bolts any.

My worry wasnt the bed cross sections as they are all welded on the horizontal plane and then they are also all holding each other from moving too much. It was heat in the top and bottom of the rails that i was worried about the steels bending on the vertical plane.

I welded the side rails on to the big section and as it was bias towards the very bottom of the sections they took a little bit of the weight off the 2 end feet.. they went from not being able to rotate by hand in a million years to getting half a turn on them.

Yesterday i shuttered in down the side of the rails and built a moat on both ends by cutting a piece of box section in half. I just used some vhb tape, some stainless strips we have for letter building and loads of hot glue to fill any gaps.

I then poured the west system 105/209 in to level the rails together. I calculated about 5kgs+1.5kgs for an area about 11000mm x 50mm to a depth of about 10mm. i mixed and poured it in 2 batches.

The next 20 mins i watched im amazement as the plan all started to come together then panic set in as the mixture despite its viscosity was managing to weep between the rail section and the main sections. I tried to cover it up as best as possible and then accepted it would be fine as it was only very minor and would stop soon.

I went to sleep last night wondering if it was going to be all over the floor come today... and success it wasnt!...
