Joining 20x40 rails (strengthen under waste board )

Not sure if this will work. I was wondering had anyone tried it. I’m finally getting round to building my x-carve. all the parts have sat in the spare room for over 10 months. However looking online lots of people seem to put more 20x20 rail in the frame under the waste board. I have some sections of 20x40 on the way but didn’t want to use a lot of 90 degree corner connectors to attach it all. So I was messing with tinker cad today and though about joining the 20x40 rails together to make one continuous sheet. Do you think this would work to connect them together ?



Looks reasonable. Print one out and see how it works.

Probably get chance to print later this week. My printer is in bits at the moment as I’m upgrading some of the parts
