Hello to all
Feel confident enough to start a build log with the certainty I have that this is the way forward for me.
I’m interested mostly in creative CNC, probably a lot of plywood based design and build. With that, I’m keenly interested in exploring the possibility of going large to accommodate the full 8×4 sheet. Currently researching all the solutions out there that might make this doable. In the end, I see myself having a few of these, perhaps a very small, super rigid one for cutting aluminium.
I’ve been dreaming of drag knives and laser cutters (and airbrushes, plotters, cake icing, etc) for quite a while now, but discovering this project has brought it all back with a bang. I have been calibrating and refining my old 3d printer with a new zeal to prepare for the mammoth task of printing the required parts.
BIG, BIG THANKS to Ryan. One hell of a design, you absolutely smashed it. You can be sure I’ll be supporting you by purchasing/donating. Since I’ll be printing the PLA bits, re-using the electronics I have, and getting the conduit here in the UK, all I need is the hardware. It would be good if there was a hardware kit available via your shop.

Hope it all goes smooth!
There is starting to be a lot of interest in a full sheet machine. I guess I will start jotting down some ideas and see what comes up.
Plywood is kind of a bummer to work with careful bit selection helps splintering and such but it also dulls them pretty fast from the glue apparently. At the hardware stores around here we have a lot of prefabbed panels available that aren’t actually much more expensive then ply, If you can give those a try.September 4, 2016 at 3:07 pm #17192
I couldn’t Google any links for these prefabbed panels you reference. When it comes to engineered wood, I know of OSB, MDF, particle board/chip board and plywood. Plywood is the most expensive in the UK. Is there something I’m missing?
Going through bits is not a worry – there is budget for my hobby 😀 +1 here on you pitching in on the full sheet design. Please do put your proven skills to work on this!September 4, 2016 at 3:55 pm #17195
Pre made edge glued stuff, this search shows some but my local lumber store has a bunch and it cuts so nice. Not the same as plywood but if you can get away from it this stuff is cheap and convenient.September 5, 2016 at 2:31 am #17209
Aha, edge glued panels. I had never considered cutting these as an alternative to ply. Very interesting idea.
I wonder how much they move seasonally. Somewhere between solid wood and ply? I suppose you do get cupping on some edge glued kitchen work tops.
I know you can super strong structure with this form of engineering – glulam beams for example. But for a relatively thin panel, I wonder if they might be weaker than solid or ply.September 5, 2016 at 5:24 am #17213
I made a desk out of those about 15 years ago. The top is very stable and doesn’t move. One of the doors on the desk though has no other support and it does flex between summer and winter and mostly from abuse. I’d think as long as it has other support it will be just fine. I haven’t noticed any movement at the edge. It’s more flexible than ply is.September 6, 2016 at 2:08 am #17254
Good to hear. This has got me thinking about getting set up to rip down reclaimed timber to create edge glued panels.
Lots of advantages it seems. Reclaimed, looks good, cheap, reasonable structural integrity, good to work with.
Just sold my table saw, but moving to a new house with a huge workshop space in the garden.
