Fantastic work @moshiach77, many thanks for sharing this project with the Workshop community. We look forward to seeing the other two raised beds you are making.
Now I'm back from holidays, please let me also extend a very warm welcome to Workshop. We're really pleased you could join us and look forward to seeing more of your handiwork. Feel free to post whenever you have something to share or need a hand. And please let me know if you ever need help getting the most from the site or have any feedback about how we can make Workshop even more useful to you.
Thanks for joining in the discussion @fishingfan. I'm sure @moshiach77 will get back to you as soon as possible and answer your question about cutting the corrugated sheeting. I'll also tag some other handy Workshop members like @Brad, @ProjectPete and @redracer01 for you who also might have some advice.
Welcome to Workshop. Please post whenever you need assistance with a project or have something new to share. We look forward to reading all about your projects and plans.
Traditional way is to use niblers, I have a metal cutting circular saw and you could also use a multitool or a jigsaw. A cutting disk in an angle grinder will do it but you will have to live with the bur it leaves and either cover it or clean it up and keeping the cut straight can be a problem. Snips if you like a manual option.
Another useful thing is a guide clamp. https://www.bunnings.com.au/craftright-50-aluminium-clamp-and-cutting-guide_p5860136
Nice work @moshiach77 - given the fact the cut ends are covered/concealed, I'd probably just rip through it with an angle grinder and give yourself an opportunity to practice cutting straight lines on wonky material.
Otherwise @Brad's suggestions all work too
@fishingfan I used 1mm cutting disk on an angle grinder and clamped a piece of angle iron to the sheet as a guide.
Thanks again for sharing this project @moshiach77. It's already proved very popular.
