New Dome Observatory Build
Posted 14 April 2014 - 07:36 PM
A technical college not too far from me has industrial laser-cutting workshops that get almost no use because these days their students do most of their learning on job sites. The tutors and staff use the workshops for their personal projects now, and are willing to cut ply arcs for me at a very low cost.
The computer-controlled cutters are fast and efficient, with absolutely minimal wastage. And of course it means I'm not fooling around with jigsaws and routers and making a huge mess of it all. Any off-cuts can be accurately shaped to fit between the arcs, or for anything else, because the computer has no problems cutting figures, where I definitely would!
On top of that, ply prices in the area have collapsed due to the vast quantity imported into the region as a result of the Christhurch earthquakes and the subsequent repair jobs. It's still way more expensive than it is in the US, but much cheaper than anywhere else in NZ.
Maybe contacting your local technical colleges could be worthwhile for anyone planning to cut dome arcs. The cost would likely be low and the savings in time, labour and wastage would be immense. (Well, certainly in my case, anyway! )

While I appreciated the video I was honestly blown away by the room you have in that shop..
I have to move my drill press to use my joiner and have to use my outfeed table on my cabinet saw as a workbench ...

And the big question, have you picked a name for your observatory yet?
