A possibly quicker way to remove old paint off steel parts is to hot-tub it in caustic soda solution
(sodium hydroxide)(drain cleaner).(NaOH).
I have a small plastic drum of it mixed up, and just boil it in an old electric kettle and then pour it into an old steel drum with the part in there. The old paint often sloughs right off.
Watch that hot caustic is - hot caustic !!
It will eat skin, flesh, clothes, eyes and low flying aircraft if it comes in contact.
So old clothes, safety glasses and gloves are not just a good idea...
Watch that alloy parts and hot caustic are deadly enemies too, so keep aluminium well away.
Hot tubbing is how the iron engine reconditioners clean up old engines.
Dissolves grease and oil too, although these are best gone before you begin.
Watch too that when you add the dry caustic into (cold) water, it can spit back,
so stay well clear. And into hot water is a no no, can be quite violent.
