We needed to tip over an end cube onto a side so that we can replace the base flange with one with a breadboard pattern so that we can internally mount optics. We also need to do this to put on a custom base so the end cube can go on an optics table. To tilt the cube this, we attached eye bolts and shackels to two of the end cube lifting points and lifted the cube. We used 5 washers on each eyebolt so that the flared end made solid contact. After lifting the cube, we tipped it over onto its side by lifting the 5" long reducing flange (10" CFF to 8" CFF). It's now resting on a piece of foam that can support the cube and is long enough that the 14.5" diameter base isn't hitting the table.

We then unbolted the base, wrapped it in clean foil, and attached my custom base (with a copper gasket of course). We had some trouble getting the gasket in, but I eventaully got it by putting the gasket in the flange and some trial and error. We then added the 12 point silver coated 1.75" long 5/16-24 screws from duniway. There were three problems.

1. I forgot to add washers to the screws. Kurt J Lesker says its optional, but I think this is best practice and we have them.

2. The heads of the 12 point screws stick out just past the custom base.

3. The copper gasket was still visable after tightening to a 180 inch-lbs spec. I don't think this spec is correct and we should tighten more.

I ordered some zinc coated hex bolts from McMaster that should arrive tomorrow (I couldn't find silver coated hex bolts after looking at a few suppliers). We can solve all of these issues then.
