Sydney Harbour Bridge B: New CNC Router / Laser Project Launch!

Jon Off CNCKing.com News,

I’ve documented across almost a dozen blog posts my conversion of the original Sydney Harbour Bridge I made a few years back from a laser cutting project into a CNC table router friendly project… it was quite a task but everything worked great!

As the old bridge is still structurally sound, I’ve decided to keep it on the site for people with smaller lasers or who want to cut something quick as this bridge is bigger! About 80cm long vs the original that was 2/3rds that. Some customers were having issues with the spacing of the spans – if your laser wasn’t in focus (or wasn’t capable of very precise cutting), you’d basically produce a bunch of ashes, in this model, I spaced them out quite a bit more to prevent this along with a few other optimizations across the board.

As this was meant to be CNC routed, it can of course also be laser cut – so I’ve included both the rounded t-boned version of this model and the non-t-boned straight 90 degree version for you guys out there with a laser… both camps will be happy!

Measurements of the completed 62 piece model dimensions @ 6 mm (1/4 inch) thick material are L: 800 W: 130 H: 180 (mm) or L: 31-1⁄2 W: 5-1⁄8 H: 7-3⁄32 (in).

I’ve included the 3D animation of the original bridge a little further below so you can easily contrast the slight changes I made.

You can get this project right now under CNC Laser Projects / Buildings on CNCKing.com – it’s labeled with a “B” so don’t confuse it with the original… which doesn’t have this extra designation. It’s close enough to the original as it is!
