Jazz, looking at your base drawing what is the purpose of bolting the frame when only the connection between the rail support rhs and the frame will need adjusting to align the rails?

Bruce

Technically it doesn't need to Bruce but it does have a few benefits (Eh he Lee taught me to spell that correct last night. . :rofl:)

First the thing weighs a bloody ton so makes transporting and siteing that much easier. It also allows so much more adjustment in all area's and makes setting up that much easier.
If welded solid then your stuck with any errors without resorting to grinding or re-welding, it also very difficult making sure everything is square and without twist when welded solid and often the heat from welding can twist the frame. This doesn't tend to happen when done how I've done it and can easily be adjusted out or shimmed out when bolted together.

In the past I've done it both ways and this is by far the better way in my experience. Yes far more work but worth the effort IMO.

Junkie:

You need to add some triangle plates to the corner uprights where they meet the cross brace, like the pic below. (Take no notice of rest of frame it's not complete here, still needs corner braces amongst other things)
I can have mine going upwards because there's the adjustable bed which they don't come above but if your not having an adjustable bed then just flip them and take down towards bottom corners. They really stiffen the frame up and stop any sideways movement, they also make getting the sides square to the base very easy when initially setting up.
Don't be put off with bolting, the frame in the picture is unbelievably strong but yet very easy to setup due to all it's adjustment.
