DIY Tesla Impulse Turbine

[The Ignoble Troll]

Well, that's not good,... as I suspect the stainless shaft will always rise to at least 100° C.

The next test run will be interesting,...I replaced the melted spider with quick-set epoxy, essentially making a replacement spider using epoxy. If this too fails, I will use either a high temp epoxy or high temp silicone.

I wonder if high temp rtv gasket maker might work?

I wonder if high temp rtv gasket maker might work?

We're singing the same song ,... high temp rtv gasket maker is what I meant when I said, high temp silicone. Either the Red or the Copper should work, but both will likely require a filler material as they both dry very flexible. Unless a solid powder is blended in, the final spider may be too squishy soft.

I've found that all off-the-shelf quick-set epoxies remain slightly flexible after they fully set, a bit like hard rubber, which is close to the original spider material. Even though I don't know their temperature limits, due to their similar flex properties as the original spider, this is my first choice.
