Great work, I check the forum every day to see the latest progress. Can you tell me about the center spider, is it a cast piece, a weldment, or what? Can you post the prints? Thanks, enjoying this very much.

Here you go, the spider is an assembly with three concentric rings or hoops, and radial axles.

Thanks! The spider wheels in the photo in the 2nd page of this thread appear to have a flange and to be running on a rail, is this correct and will you be doing the same?

Brendan,

Another set of great pix! I notice in the last one a pipe of some sort in the lower foreground. Is that the water line or the telephone/alarm line?

That was the water pipe to the shop. The phone and alarm lines to the house suffered a similar fate. We ran temporary phone and alarm lines to the house today. We will put in permanent telco lines and fix the water line when the concrete work is done.

That is some hole.
I bet you are glad it did not have to be done with pick & shovel and scraper pan with horse
like the old days.

Wow - Jeff does great work.  The exposed soil appears like it should give good bearing to the foundation. 

The edge of the turntable looks like it will just edge past the shop extension's wall; how close will it be?

Any chance we can save the fill for the wash outs on the mountain?

The bottom of the hole is approximately 5 ft bigger than the finished concrete work so we have room to work. The top of the hole has an additional step back to keep the hole from collapsing.

Most of the material removed from the excavation would not make good fill for the washouts. You have to dig down to about five feet to get to good hard clay. The contractor hauled about 280 yds of material off site and left the rest for backfill were we dont need to use gravel or sand.

I had asked for some to stay on site for use in water run-off control around Sheepscot. One load would probably do it. But there are ditches to dig yet so perhaps those will yield enough.

So, how deep is the turntable pit on the west side?

That hole is really big.  It's around 6 feet deep.  This afternoon Jeff was putting in a stone base. 

I really wish we'd held on the material - it would have been useful somewhere eventually.

Bill the bottom of the hole in the pictures is about 7 1/2 feet below the bottom of the siding on the shop building. We have a benchmark screwed onto the side shop at finished rail height. There is 12 inches of stone going in the bottom of the hole and the finished grade will end up at 87 inches below rail height.
