Looking nice! Love a good laser cut project.
If you’ve not seen them before these joints are cool..
If you overlap the top edge so the slot is closed it will make the whole thing much stronger and also way easier to assemble as it won’t fall apart when you’re trying to put the panels together! The slot for the nut is just tiny bit bigger than the bolt across its flats so it’s held captive.
Also check out living hinges for laser cutting, they really extend the possibilities of the projects you can create with 2D sheets.
Living hinges will definitely work with that material. For ultra tight radius’ cut out slots (~1.5mm width) with a radius at the ends, you’ll be able to get it to go round a 10p piece. I have some designs if you get stuck.
For that acrylic design above you’ll make life way easier if you have an overhang at the ends so you can make the edge slots closed rather than open. I can send a pic if that doesn’t make sense!
Nice work i like the racing seat.
I teach DT/engineering in a secondary school so we use the laser all the time, probably been using one for about 10yrs. 40w should be more than capable of 3mm ply, might be worth checking your mirrors and lens are clean and aligned to make sure the power isn’t being wasted. 3mm acrylic will usually cut better than ply. We’ve just got a new one from HPC that can cut through 15mm acrylic and 9mm ply in one pass. I’ve just bought the old one from the school to use at home and that is quite old but it will cut through 3mm ply and acrylic no problem, managed to get it for £100 as it overheats when you do a long job, hopefully I can have a play and improve it slightlyNice one! That’s good to know. Have you been lasering long?
I’m sure those can be incorporated into the design to make them less obvious too. Plus they have the benefit of being removable too. I still need to try acrylic. I have some sheets but still have reservations that my 40w laser will cut through it as I’m having to do multiple passes on 3mm plywood at the moment as it is! Really need to upgrade to a bigger machine at some point.

What sort of glue to you use with plastic/acrylic?
That’s cool. Not sure I could handle the kids though but that’s probably my three year olds fault. I guess the older ones might not be as bad. Haha! I did clean them when I fit the new psu a week or so ago. (Also changed the tube but the other seems doa which is annoying) i’ll give them another check later and check the head one as that’s always a pain to get to so could be a bit dirty. Do you have much experience of tube life? Could by existing tube be giving up if I’m still having problems? Wow that new one sounds like a beast! I was going to go HPC but chose these other guys instead and they’ve now gone under.. however my next one may come from them I think. That’s a bargain for you with the old one too! I take it it’s not water cooled? Mine uses the cw3000 which seems to be the standard for entry level water cooled lasers. Even on long photo engravings/cutting sections I only just about see 30 degrees I think. Hopefully you can get it fixed.
Should also have another update tonight. Ran out of paint and then had to use a different primer and now my colour matching is a bit rubbish. I’m hoping I’ve just fixed that but need to wait for it to dry.
Have you finished it now? any more photos? Build looks very good - them joints are perfect. Like others I have wondered about building in a drawer but others have had issues like with earthing - does yours work well.
