When I said I can't weld it wasn't meant I won't or can't learn just that, at the moment, I can't. Part of trying to avoid learning how was a desire to get cracking but as Jazz said it doesn't need to be pretty so I'll add welding to the list of things to learn.

Oooh the machine size question. I've not said anything so far because I suspect I'm making a newcomers mistake of biting off more than I can chew. I'd like a cutting bed of about 1500x1000. One of thing things I want to do is carve / pierce panels for the fronts and sides of cabinets. I could probably get away with a smaller bed but I think that's a good size to aim for.

Can't wait to get drawing some plans but I'm a bit short of time at the moment so you might be in for a bit of a wait until I can post some here. I can't realistically start building the CNC until we've had the workshop built, a process which is really dragging on.
