Resurrection of a CFEI 100 KVA Induction Furnace

Pete yes that’s my fear !
John, I’d not thought of fire as it’s a bit close to the goose fence , but I had considered my Karcher MPDS battlefield decontamination unit, as it’s a steam cleaner on steroids but it’s rather deeply buried at the back of the shed.
As I’ve solved the not starting issue with my small Chinese pressure washer (*) I’ll have a go with it this morning. After all it was a sensible suggestion from Pete some time ago to try and flush out the gap with a pressure washer.
(* why would it not start? Oil sensor switch saying low oil when dip stick says full! Importers suggestion: fill the oil until it runs out of the dip stick hole! I think they’ve had this issue before. It’s a copy of a Honda engine mounted in a wheeled frame and I suspect that it sits rather more tilted than the engine designer intended)

So with the finest (so highest pressure) nozzle fitted I gave the manhole cover an intensive session with the pressure washer. It was obviously doing 'something' as every now and again a great spurt of brown rusty water would came back at me in the face !
I blasted it vigorously for quite some time, then gave it more violence from the sledge hammer before again an intensive session with the pressure washer. Not easy to see what it's done with all the water about so I blew it off with an air gun.
As you can see from the pictures below the 'gap' is much more pronounced in some places but still totally jammed full in others - it MUST have helped I tell myself :clap:

How about another approach, Andrew? If you have plasticine or similar, plug the elongated holes around the edge, build a dam around the periphery and flood the whole area with a concentrated solution of vinegar/citric acid/phosphoric acid and put a lid on it to prevent evaporation?
awemawson:
Another good suggestion Graham that I will put on the list to try.
I have a recently retired and recently divorced Fireman who got stuck in isolation on the farm in his caravan by the virus when his arranged site closed and he'd already left his other half. This morning he's seen what I'm doing (from the prescribed 2 metres!) and is taking it as a personal challenge that he cannot open it.
Who am I to deny him his entertainment - it has to be better than just polishing his caravan, he'll have no paint left :clap:

Hmm, I've never heard it called that before! :lol: :coffee:
Can you get a pry bar into the slots at the edge? Maybe you could see some movement?
