Resurrection of a CFEI 100 KVA Induction Furnace

Why not drill a small hole in the lid and pass a borescope / plumb line through to have a look before going through the effort of opening it. It might have been filled up or gotten blocked up with debris.

24" is a heck of a bore hole!!!

The November 1939 document actually says diameter at top 5 foot 9 inches :bugeye:
But it’s the manhole that’s 24 inches !

Glad to say that the first half of the floor had mainly dried over night with the exception of a bit by the wall where I was probably a bit enthusiastic with the sodium silicate solution.
It has made a very noticeable difference to the previously rather dusty surface - you can draw a hand over it and no dust comes off at all :thumbup:
So it was a case of 'rinse and repeat' this morning - moving everything to the now sealed end using the pallet truck, vigorous sweeping and vacuuming and another session mopping 3:1 water / sodium silicate solution to the newly exposed floor. The wind has got up and this lot was drying much faster as I have doors both ends.
It's my intention to give it a coat of grey industrial floor paint when the seal is thoroughly dry, and although I have the paint I don't have sufficient white spirit to dilute the first coat, and I only have one 12" floor roller. In these Covid-19 isolated days it's not just a case of popping out to get them so I've orders in place - at least it'll give the seal longer to dry (sell the positive !)
Stay safe everyone.
