Resurrection of a CFEI 100 KVA Induction Furnace

Waiting for concrete sealant to dry is rather like waiting for paint to dry - boring :clap:
So I had another go at the manhole cover. I'd intended to pressure wash the joints as suggested by Pete. but my brand new portable petrol washer that's only run for one day refused to start - no spark :bang: And it's far too much of a fag to dig the big steam cleaner out from the Tractor Shed as it's buried again at the back.
So I went round the joint between the frame the the cover with a small cold chisel clearing as much rust as I could, then giving it a good talking too with a sledge hammer - I assume it's malleable iron not just ordinary cast iron ! Still no movement so I've started a program of squirting Plus-Gas into the crack - it is soaking in so may do some good. When I've done that for a day or two I'll gently vibrate it with my Kango concrete breaker.
At the moment I'm loath to drill holes in it as undoubtedly there will be strengthening webs in it underneath that I don't want to hit, and the light on my endoscope camera is not too bright.
Re-reading the borehole survey report there are a few contradictions and I think, looking at page 6 it may be referring to 6 bores made in the period 1922 to 1962.There is also a reference to 'Back Filled it to 90 Down' however there is also a reference to 'Filled in Information from visit 16/10/62' - so who knows - certainly not me :scratch:
Anyone know how I can print a copy of the 9 pages of that report ?
awemawson:
This looks to be the same specification so I better be careful!
Pete.:
Bit more fragile than the 60-tonners outside out site :D
What I would do is measure the hole diameter in the key slots. Get a bolt about 150mm long with a shank that fits closely in the hole and cut the sides off the head so it can drop in and turn through 90 deg. Get a piece of box section steel maybe 6 foot long and drill it over-sized for the bolt to allow a bit of wiggle. Measure the distance from the key slot to the edge frame and weld a chunk of flat bar on the box section such that the bar acts as a fulcrum bearing on the frame. Now pop the box section over the bolt and run a nut down it, and start bouncing on the far end to lever the cover up.

You could save each page as an image and then print it to PDF (at least, in windows)

I can only get about half a page to a screen for some reason :bang:
