Largest brake discs

[MissTaniaThomas]

I’m trying to commission a company to turn a crankshaft into a dining table, and ideally I’m seeking advice on a oversized brake disc as a foot.

Now I’m aware some of the larger ones at 400 and 450mm, but how big do they ever get?

[stevieturbo]

As big as you want someone to make them.

But perhaps some heavy vehicles, machinery etc etc might be something already in production in a large size.

But factor in you probably want to be able to move the table too.

Ideally, I’d be seeking a scrap or used disc, keeping the costs low...

This may not be the biggest now, but at least recently the largest discs fitted to any car were the fronts on a Continental GT or Flying Spur.

Dead cheap and easy to find once unusable. £20 from a Bentley dealer or specialist I'd have thought. Take a packet of biscuits to sweeten your offer.

Why don't you use a flywheel instead of a brake disc? It will bolt straight onto the crankshaft....

And why do you want your dining room full of old car bits?

Each to their own I guess, but I have a strict rule, no car parts whatever in the house. It's a slippery slope. I don't mind working in a scrapyard but I draw the line at living in one.

How much will this weigh, should be wonderful all polished up but hope the floorboards are in good nick.

^ This.
Flywheels sit on cranks not brake discs and it's a bit council anyhow.

Brake disc will rust quickly too, i'd have thought

480mm http://www.efletcher.co.uk/off-highway-brake-rotor...

The Terex Titan (massive truck used in open cast mines etc.) uses 660mm discs (26")

ETA its close rival the Caterpillar 797 uses even bigger 1067mm (42") jobs. These may exceed the SWL of your floor.
