The attached photos are of a B&L Zephyr diopter. This unit has the worst hardened grease I've ever encountered. Freeing and separating the focus components was much tougher than for any green grease I've seen. This stuff is almost like a cement.
Alas, the diopter is defeating all of my attempts at disassembly. The inner and outer shell almost seem to be glued together. As you can see, the single set screw has been removed, but the fit between the two shells is so tight, and so blocked with old grease, that I cannot get any solvent in between (having tried acetone, WD-40, and Liquid Wrench.) I have heated it thoroughly with a hair dryer, but it still does not budge under two opposing strap wrenches.
Any further ideas? I hate to give up on this noble representative from Rochester.
Thanks for any and all suggestions!!
