This tweetroll covers more work with Tesla Turbines and turbines in general
Tesla Turbine prototype finished.π₯³

Lots of lessons-learned, and performance is far from adequate, but it does spin, and I designed it to be modular so I can drop in any rotor I want.
I'll post some clips later today.πhttps://t.co/Hksw2fKyfo pic.twitter.com/KRskGZWW5Y
Tesla turbine test this morning:https://t.co/gu9SYSKtas pic.twitter.com/4BgWS2AEHL

First lesson learned, looks like the nozzle has a huge impact on Tesla turbines.

I'm getting better performance blowing air straight into the rotor.https://t.co/FvM8ardvJl pic.twitter.com/GF9LUKbeod
I'm at a crossroads on what to work on next on the Tesla turbine.
— Hakasays (@Hakasays) August 17, 2020
I could build a steam boiler and turn it into a steam turbine,
rebuild the rotor for improved speed+power,
or try to add 'air bearings' to basically eliminate friction.
Thoughts?https://t.co/gu9SYSKtas
Yeah, this is WAY better for low-speed torque

Looks like I'll have to make a couple out of Aluminum this week pic.twitter.com/UTD6Rs5ZJA
Trying out a 3d-printed turbine rotorπhttps://t.co/hLn1YxCPut pic.twitter.com/d0CiUbPvW7

Tesla turbine project,

Picked up some hybrid ceramic bearings to reduce friction, but they are a different size so I needed to machine new bearing seats along with it. pic.twitter.com/0IS6ktrpDJ
The 3d-printed turbine rotor worked really well so I decided to CNC machine one from aluminum.

Looking good so far but it will probably need some balancing before I can spin it up pic.twitter.com/O8zBBLAbVd
BTW Tachometer shows rotor at somewhere around 12,000rpm peak with this configuration.

With the 3d-printed rotor and the hybrid ceramic bearings the turbine definitely has a better kick to itπ

At some point I'm gonna have to find a way to hook a generator to it, but may have to build one DIY because few are designed for >10krpm operation.https://t.co/pmfsqkIyBY pic.twitter.com/leGcpMSUkf
I think for the turbine project I need to start hook it up to a generator to start gauging the actual torque+power produced by it.

Gonna start with a spindle motor and an RC brushless to see how they perform.https://t.co/pmfsql0a0y pic.twitter.com/MnYtUepcr0

Well that was definitely a derp…
— Hakasays (@Hakasays) August 21, 2020
Just realized I machined the aluminum rotor facing the wrong direction from what I plannedπ
Maybe it'll still work good? pic.twitter.com/qxkEy6b8pL
3d-printed a few different sized nozzles to see how they perform on the turbine project.

It seems the tiniest sliver-nozzle works best, but it may not have as much torque once I put a load on it.https://t.co/Q73x6pvU3A pic.twitter.com/qDFupGtfN5
Lefthand turbine this timeπ§πhttps://t.co/28dXfl0qV1 pic.twitter.com/filCba9oHE

Got a box of old hard drives from a friend.
— Hakasays (@Hakasays) August 23, 2020
Gonna see if I can reuse the platters to make another Tesla Turbine rotor. Eventually pic.twitter.com/A2up4xIqqf
Machined some aluminum cans into another batch of ultra-thin washers.
— Hakasays (@Hakasays) August 23, 2020
Real handy to have around. Probably use them as Tesla turbine blade spacers pic.twitter.com/8FCQ0zdwZS
I had a shop waterjet some Tesla Turbine blades to test out sometime.
— Hakasays (@Hakasays) August 25, 2020
Also salvaged a bunch of old hard disk platters that might work as well..
Now I just need some free time to screw with 'emπ§π pic.twitter.com/KfTOahKH4t

I am become death, destroyer of hard-drives.π΄ββ οΈπ§
— Hakasays (@Hakasays) August 26, 2020
TL/DR I tore apart a lot of old disk drives for spare parts.
The platters I think I can use for Tesla Turbine blades…π pic.twitter.com/91qFshXaHe
Gluing together some rotor blades for Tesla Turbine.π§π

Unfortunately it looks like I'm gonna be busy with actual job work this next week so I won't have updates for a while. pic.twitter.com/X8uAjRLESR
