The pickle pickers came off nicely and both magnets seem to be glued on okay. The alignment of the face magnets look pretty good, but we will only really know once we suspend the mirror, check the pitch balance, and put in the OSEM coils.

I brought the ETMY suspension tower + OSEM coils out of the vacuum chamber into the cleanroom. Given that the old wire had a pretty sharp kink in it, I removed it with the intention of suspending the optic with a new length of wire. I noticed a few potential problems:

Attachment #1 - ETMY tower is different from ETMX tower: 

• The ETMY suspension seems to be of an older generation - it does not have the the two secondary wire clamps. 
• The top piece was attached to the body of the tower using non-silver-plated screws. Steve tells me this is the wrong type, and we can switch these out when we put it back together.
• The wire clamp itself doesn't have much of a groove from the wire. But the wires have made asymmetric grooves in the tower itself (the left groove is deeper than the right as seen in Attachment #1), that are clearly visible. Should we get these grooves removed before attempting re-suspension? How do we want to remove it? Steve thinks the best option is to send it to the shop for milling, as there is hardly any room to rub sandpaper along the piece because of the pins, and these pins don't come out. 
• Or do we just not care about these grooves for now, if we are planning to use new wire anyways after air-baking the towers? 
• Steve thinks we should have a few spares of these top blocks handy (the latest version, with the secondary clamps), he wants to know if we should place an order for these (we already have 10 spare wire clamp pieces available for if/when we need them)

Attachment #2 - the base of the tower is significantly rusty:

• A few wipes with an acetone soaked rag yielded quite a lot of rust
• Steve thinks this is because the wrong type of stainless steel was used
• Does this have to do with the cage being of an older variety? After a few vigorous wipes, no more rust came off, but the rusting process will presumably keep generating new rust? Is this a concern? Do we want to change this piece before putting the tower back in?

I am holding off on attempting to re-suspend the optic for now, until we decide if the old wire grooves need to be removed or not. If we are okay with re-using the same piece as is, or if we are okay with using sandpaper and not the machine shop to remove the grooves, I will resume the re-suspension process. 

Eric suggested another alternative, which is to use the old ETMX tower. I don't recall it being rusted, but this has to be checked again. The other problem of the wire-grooves would possibly still be an issue.

Regarding the vacuum bake of the ETMs, Bob tells us that the best case scenario we are looking at is September.
