SORRY - I took the photos down, just thought it best. Thanks for all the input. PM me if you're really curious. I'll post something when it's done.


Sup BG. Maybe not the right place for it but I have faith in the collective knowledge of the guide, and I want to hear your thoughts.

A few weeks ago my school was contacted to design a trophy for some Clean Technology business award. We had a few students taking part and some instructors and technician. After breaking off into smaller teams we went with 3 concepts, and of those 3 mine was chosen. I intended it to be wood with aluminium placards, but the program coordinator insisted we also include a render in chrome, despite my argument that it would be a bitch to make.

So as I planned to move home before Christmas I had made it clear that I'd be gone when it wrapped up, but since it was chosen I have to at least line up the fabricators and clarify design issues.

The base is nearly impossible to make, but I have some ideas of how a waterjet might cut it. (concentric rings at an angle) and for this we will either do it this way, only every other ring, or alternating metal and wood. Any thoughts welcome.

What I'm struggling with is how I will attach the 10 large metal plates to the central spindle. It's a big straight pipe with enough wall diameter for tapping, and the plates themselves may be around 1/4". Originally some brazing was going to be the ticket, but it would be too tight to get in there after half the plates.

About to tell the clients we will have to use countersunk connector bolts, but it does look shitty.
Anybody know of a simple, strong, good in tight spaces fastener? Or a stud bolt with RH and LH threads?

Any leads appreciated, and no leads appreciated too. Thanks

Couldnt a good machinist make you some RH&LH-thread studs/custom fasteners?

That was my thinking, pop a little knurl in the middle and just threading the tapped plank to the pins holding it. Likely the simplest solution, and clean too, thanks!
Any other wise-guyz?

where are you? are there any places around you that can 3d print metals?

Looks like a building out of Mass Effect.
