what can I use for a steampunk tesla turbine?

I would like to know so I can make one smaller than the one on the previous instructable

Do you want your Tesla Turbine to actually work, or just look good?
If you want your Tesla Turbine to actually work, then you will have to decide:

1.) Will it be powered by compressed air, or water pressure, or rocket fuel, or what? Low pressure (<40 psi) or high pressure( 80-100 + psi) ?

2.) A case will need to be built to contain the above-mentioned pressure, and with a nozzle to speed up the flow into the turbine, and an outlet at the centre. The case size will depend on the size of the discs selected. You mentioned a smaller turbine, so perhaps 2 inch or 3 inch size would be good.

3.) You will need to use a shaft and bearings to get power out. It could be a shaft with skateboard bearings, or a CD player motor can act both as a generator, and has a shaft with a bearing. I made a bicycle generator work in a similar way as a generator for the turbine. Or, you can use a magnetic coupling, like in all of my Tesla turbine instructables.

Brass or copper pipe would look great for a steampunk Tesla turbine. End caps could screw on or be soldered on, with a big brass pipe outlet. ( check out the outlet on this TT instructable, https://www.instructables.com/id/Tesla-CD-Turbine-With-Scary-Steampunk-Laser-Pumpki/ 

You could use the smaller-sized Mini-CD's (2.4 to 3.1 in) as discs. I made stronger custom-sized 2 inch stainless discs by getting them cut out of .020 tool stainless by a water-jet place. They were about 3 to 5 bucks each to do. I made a clear polycarbonate case for them, again cut by water-jet.

Let me know if you want more advice!
