For example, our local Home Despot store sells at least 3 kinds: General Purpose (contains fairly large pebbles and will clog your sandblaster right away), "Kiddie Sandbox" (contains some fairly large grains and may clog even worse than GP); and "30 mesh", which is what you want. I'll betcha that I could blast a Reynolds or Columbus frame with 30 mesh pretty quickly without damaging it, but I've never tried to. I have, however, blasted a lot of auto body parts made from 19 gauge steel without doing any discernible damage. Mess is not a problem because I have a little blasting area away from buildings and lawn, where I can just rake the sand into the ground afterward.

I have had 5 frames cleaned and powder coated in the last 10 years and while I don't know HOW they got that paint off, it wasn't with sand blasting because I returned to see how they were doing and saw absolutely no paint and not a mark on the frame or threads that would suggest sandblasting which they did do on cars and car parts. Jay's comments about using walnut shells may have been how it was done but not with sand of any kind since it leave obvious marks.

I saw a drawing of a Two-speed rear hub where you pedaled backwards for low
gear and forwards for high gear....did not save the link....sigh.

But, there seems to be a new Rohloff competitor out there now....

https://www.cyclingabout.com/kindernay-xiv-hub-14-speed-internally-geared-hub/

I have not read the site yet.

Asto my earlier thought of a Pinion with a Rohloff, I don't think that would
be allowed since I think Rohloff specifies a minimum tooth count on the
chainring for mechanical torque reasons. Was it 46 or 42?....something like
that.

Several, the Bendix Automatic in three versions (two with
shoes, one with ND type discs), Sachs Duomatic, etc.

The mechanism is much like a Parket Jotter. Each iteration
of backpedaling increments the index set- high, low, high,
low...

p.s. cable-actuated two speed planetary hubs go back the the
Sturmey Archer Type X of 1902.

There are obvious advantages to the Sturmy-Archer hubs. But efficiency of an internal gear drive is not one of them. Though a watertight drive train surely is. Fully enclosed chain and full fenders and the ability to speak Dutch would make you a real cyclist..
