If you looked at the older parts of his blog, you will see that he had the laser cutter do the work of cutting out all of the parts for the model from sheets of acrylic. It worked really well for that and everything fit together like a swiss watch. They can do wood but it burns the edges quite brown. I don't think they have the router setup. I know some folks who have built these things but none of them are here in Winnipeg so we did it the hard way. Thankfully, he is close to being done so I will be back to my own projects.
I have a new garage door plus opener to install when the weather warms a bit and it has one of those laser doodads too. My wife has really liked the tennis ball we put up a couple of years ago to tell her when she is in far enough but I find it a pain when working in the garage without the car present so am looking forward to that swap.

The school might have one? But interesting project whichever way you make it. An aside -- I bought some garage laser parking pointers at Lowes for cheap, they have a shake sensor that attaches to the door opener and when it starts up, the laser comes on for a minute or so. Anyway, I'm starting an addition to the house, a timber frame, and I have this idea to mount a bunch of little mirrors on the frame here and there, with the laser tripped by a door closing or something, that will then light up the space in the frame with laser lights. At night it would be pretty cool just from ambient dust, laser beams going every which way. Or it could be my earthquake sensor. --R R A Bennell wrote: > My elder son is doing his Masters in Architecture.
