How about mounting a cutter bar to the axle spindle and powering it with an electric drill, lots of very fine passes should give you a good surface and no lathe required. You could even mount a die grinder to the spindle and rotate the spindle by hand as you slide it in and out.
I used that method years ago on a 69 bonnie and it worked perfectly, so I'll second Mr Shox on that one.

I saw a drum in wheel being ground in a mates grandads workshop years ago.
He had fixed some sort of bracket to the headstock and the wheel was bolted to it, thru the bearings.
The lathe chuck and rim had a belt around them, and I think he had his bench grinder mounted on something
bolted to the carriage and he was making passes with the carriage.
The workshop was upstairs in a house and all the power came from a light socket;-)

if you are going to try something like this you will need something very rigid that will stay true to the surface you want to skim and ideally the full width of it, also do it with very light passes so that you don't remove more material then is necassary

If properly supported this would work. Could even get away with a demel type tool, with light passes [most important]
However I would be indicating the runout first and checking that it hasn't been caused by galvanic corrosion, buckling the sleeve, and the the casting. If so you're wasting your time IMO.
If it was me I'd spend the time painting another wheel in better condition. It will probably take less time as well

As I've already said distortion COULD be due to corrosion between the steel liner and the alloy wheel. This needs to be carefully checked before any machining.
Think about it - what has actually caused something that was originally perfect to become distorted ? Steel brake drum lining don't normally become distorted for no reason
Sourcing a better wheel, and repainting, gets my vote as action to take.

it is a very real possibility that corrosion is to blame, it is also very possible depending on how oval it is that any machining will go through the steel liner rendering it scrapAs I've already said distortion COULD be due to corrosion between the steel liner and the alloy wheel.

Did you check to see if the rim runs true? I know someone that did all the above and powder coating with a pair of wheels that were out of true!
Do you know if they are a shrink fit sleeve or the wheel is cast around the iron drum as a core? Smashing up a spare scrap wheel would be the way to find out.

Generally the drum surface is cast into the wheel. They can be machined out and replaced on spoked wheels, but I would think the wheel is scrap if its cast, as this will cost more than a good used wheel.

Have you checked with dial gauge the concentricity of the actual drum to determine how bad ? That would also highlight any "high" spots so you can then see if a crack or possible corrosion in that area. I suppose in theory you could use the swinging arm and spindle without the brake mechanism as a "stand".

It would probably be possible to machine out and make a new insert, oven, freezer, press, etc. but if your paying way way cheaper to find another wheel.
My well have been miles out from new, some old stuff is horrendous from a quality point of view

The LC wheels are known for this problem so getting a good second hand one will be hard! It's got to be worth a try skimming it. As mentioned above about new oval castings, I've just machined a XS 650 spoked hub for my cafe racer and although the drum is true the alloy casting was well out! It'll balance much better now though.
What's the diameter of the wheel without the tyre?
