TR-1 MOTOR UPDATE



I'm making slow but steady progress.  I managed to get the nozzle ring close to final diameter last night.  I'm hoping to get this piece finished in the next day or two.   The other parts will be either 12L14 steel or 6061 t-6 aluminum, so fabrication should speed up once this part it finished. I mentioned the relative ease of machining 12L14 versus 1018 yesterday, the thing I forgot to mention was clean-up.  With 1018 I tend to get these long strands of barbed steel wool that sticks to everything.  It tends to shoot off the lathe in every direction, it gets in my hair, wound around the chuck, or onto the tool holder. With 12L14 I tend to get a neat pile of chips right under the cutting tool which is much easier to clean up.  It's the little things...

Where did you buy the 12L14? I've been making my nozzles from 1018 until I started using stainless but that's getting pricey in the larger diameters.
