Paul talked to me about getting my grinder with a cutting disc and my Sawsall two days before we went there but then he told me it wouldn't be necessary as the washer was supposed to have already been uninstalled!
When I saw that Paul was disconnecting the hoses that were still connected to the huge laundry sink, I began to seriously doubt that it had been unbolted from the concrete floor and moved recently as Paul was told! Didn't take long after that to see it was still bolted and that we had nothing to remove the bolts! (and I doubt I could have plugged a non-battery operated power tool anywhere in that basement as the two outlets (on the ceiling and not accessible without a stool!) dated from around 1910 and didn't look like modern ones at all! There was still a rotary switch on a porcelain fixture on the wall and a socket hanging from a similar fixture on the ceiling but no light bulb in it! The washer's power cord was disconnected but I guess it used to be connected somewhere on the ceiling with an extension cord.
We went with the seller to the local hardware store to buy a saw and wrenches but the wrenches were too small (I didn't notice that the bolts had large square-shaped heads before we went there), then we tried to manually saw the bolts with the new saw as there was enough space left under the machine to do that but it didn't work at all. I went a second time with the seller to the hardware store to get some larger wrenches while I think Paul removed the ground cable and continued to try to saw the first bolt but I think the saw got more wear than the bolt itself! Then, with the larger wrenches we removed both bolts, 1/8th of a turn at a time as the access on the side of the Bendix didn't allow to turn the bolt a full 1/4 turn with the wrench. So we had to reverse the wrench each time...
Too bad we didn't take pictures at this moment!
