I saw a video of someone using a shrinker for metal shaping to cup grinding wheels. benchmark abrasives sells all different types of sanding/ grinding shapes also

Why not chemical stripper? Then any sanding is just prep work, not very aggressive and could probably be done by hand with various shaped blocks.

All metal I assume? Would an IR paint stripper work? Or a siphon-feed bucket sandblaster?
Interesting. I'll check out Benchmark, thanks!
Had terrible luck with the new generation of "safe" strippers. Works o.k. on the top layers but does nothing to the good ol' factory paint. Not worth the mess. IMO
Drawing a blank on IR? sandblaster would be okay if I had a yard that I could do such a task.
I'll give my air powered angle grinder a go and report back.

Infrared. A coworker raves about his after stripping paint from a ton of trim in his house.

Maybe look into a mobile dry ice blaster?
I had a bike frame chemically stripped here in Phoenix by Xpress Metal cleaning and it literally looked brand new. They had numerous cars in line to be dipped, but I have no idea what it cost. Fork is 4130, frame is 6061 Aluminum, stem is unknown forged aluminum.

I’ll have to see if my detail sandblaster is within reach tomorrow. I built it decades ago but it’s something you could easily make out or parts from the local hardware store. Personally, I’d go get some aircraft stripper and call it a day.
That took some effort hog, nice job 
Btw I did look for my blaster today but it must be packed up in a bin. After moving to Az and not being in my forever shop, I’ve collected like 30+ storage bins. Chances are pretty slim of me finding it at this point anytime soon but picture this.
First off I used a PCV material for the container I machined out of 1” thick sheets bonded n bolted together. That’s right I plan on killing myself according to this place. But with this design you’ll never exceed more that 50% of your pressure output if even that.
Anyhow
Starting at the inlet. 1/8” npt 1/4 turn valve at the inlet. That feeds thru two t’s and then straight thru to the nozzle via brass tubing.
Both tails of the T then have 1/8” npt ball valves. The first t just taps into the container and pressurizes it. The second t has a pick up tube that goes maybe a 1/4” off the bottom (this now becomes a pressurized siphon tube for the sand. By adjusting the two ball valves you can really dial in the media flow. More or less the siphon valve is always WFO and the pressurized valve side, just cracked in order to ventilate the container and allow the media to flow.
The tricky part is sizing the nozzle. Im not honestly sure where a store bought one can be had.
As far as the container, I’d just use a 6” piece of 2 or 3” sch40 pvc with end caps or cap and a female adapter so you can use that for filling the media n then a metal plug.
Lol, finding a nozzle was a piece of cake.
