The math is sound :-)
I found that my box section 1850x120x80x4 mm was + 2 mm bend in the middle by welding heat.
I had a +/- 1mm error in spirit level. over 1850 mm...
It all add up. so 6mm thickness... i am not sure.. i did not have the best of spirit levels
So on the ends i have 8 and 7 mm thickness now.. 5.5 or so in centre.
I had some leaks while pouring.
Mostly because of heat from the shop heater on the channel sides.
Wood dried and bended.
Can see through under the square rails through the epoxy now
Make sure to use packing tape on the sides ... best tip ever.
Ok hope this helps.
I have steel gantry so more pouring on there for me.
Get the A pack.. it is 50 gbp or so.
Grtz Bert.
