Where do I get this RUBBER STOPPER dingus? None of the articles I've collected explain this.

I got mine at a hardware store (black rubber drain stoppers). I bought several sizes, I think a #11 or #12 is about 49mm on one side and ~55mm on the other side. I don't recall the dimensions of the bigger ones. I will measure the bigger ones at home tonight.

Jim Buchana says he uses a $30 spanner wrench, which is shockingly inexpensive. Jim, which one specifically do you have?

I think its the 1054B.

Thanks.

BTW - I found some extra help at the following site, and they also have a LARGE collection of member-submitted repair guides & manuals:

I would be careful with 2 of the tool items he mentioned:

1. Kleenex - I think it has wood particles in it. I wouldn't chance it to clean the lens glass with. The lens tissue is worth the investment.

2. Can of Air - You may introduce more moisture and/or oil to the surface. Get a big Pocket Rocket instead.

About the oven thing... check the working temp ranges for your lenses, especially the ones with electronics. I am sure something like 100*F for a short time is ok or else they wouldn't be able to sell any lenses to use in the deserts!!!

Thanks for the suggestion about the fungus cleaning on v700. I got one glass more or less cleaned; although was afraid of applying the Pond's cream without testing it first, so the cream is in the backburner for now.

i am wondering whether you might want to try a less invasive maneuver with some of the cheaper lenses you have and dip them into pure alcohol, then blow-dry. note that i have never tried that before, but am assuming that if you dip the lens into alcohol sideways, it will lift minor debris and as you lift the lens and let the alcohol drip from the lens, the debris will settle on the barrel wall, which means no effect on image quality. alcohol should also help get rid of the watery marks on the lens elements themselves. it will not clean any fungi, but will surely kill it. i don't know though how alcohol reacts with the cement used to seal the lens elements. again, i have never done this, so i wouldn't do this with any except the cheapest lens to try it out first...

Alcohol could dissolve the grease on the helical and then deposit it on the lens as the alcohol drains out.

I use annhydrous methanol, for lens cleaning. Low molecular weight for higher volatility and no water.

With the rubber lens rings, make SURE you get the ones with the hollewed out middle - I got the 'skin' coloured gum rubber ones from microtools which are flat at each end and had to spend several hours on each to remove enough rubber that it wouldnt touch the front element on many of my lenses - I did this by lighting a section in the middle of the rubber on fire and letting it burn for 20 seconds then scraping the soft rubber out. NOT a nice process - extremely toxic.

I had to do the same thing, hollow out the middle of the rubber rings. Only I used a 4" grinder. Messy, but it took way less than 2 hours.

I wonder if this PEC-12, or even the Eclipse or E2 will do the same thing.

The Eclipse or E2 are the only cleaning solutions that work on my Kaeseman polarizer. The rest of the lens cleaners, including Formula MC, just leave a lot of smudge.

p.2 #13 · Disassemble & Clean My Own Lenses?

I finally got my order in. Thought I'd post it here, with notes, in case it helps some one else just trying to figure this all out.

NOTES:

Spanner wrench: I decided to get the best. Heat-treated tips, 5 shapes, for safety & also for use with other things besides lenses. If I have to work on a large telephoto, I can just get the longer handles.

screwdrivers: For the JIS standard, I'm tpld that crosspoint is better than JIS. I ordered the handle & bits considered best by Micro Tools' owner. sizes 1.7 - 2.5 should do, but I got the 3.0 as well, just in case. The 2.0 is out of stock, so that's why it's not listed below.

For tiny flatblades, the best by far is the Starret set. Wiha is also good, but I ordered the Starret.

Helical grease: Hoo boy, what a subject. I ordered Nyogel #744 ( a medium-light damping grease) plus several types of high-end bicycle grease from another source.

Filter ring removers: Sure enough, the more expensive gum-rubber ones are NOT hollowed. How strange. I bought the cheaper, hollowed set.

I ordered 99% Alcohol, as that's hard to find locally, and should be good for a final rinse.

Tools not in stock, that might help:

25-135 DENT REMOVER (Hollowed-wood tapping kit.) (for fixing dents in curved parts)

TAP-135-50 Mini Tap and Die Set $26 (for the inevitable)

=============================

T-132-34567 Spanner Wrench Set, All 5 Blades $83.18

S555Z-6 Screwdriver Set, Slotted, Set Of 6 $60.00

XPT-HAN Screwdriver Handle, for XPT Blades (New Style) $6.95

XPT-1-7 1.7 X 40mm JIS/CrossPoint Screwdriver Blade $5.95

XPT-2-5 2.5 X 50mm JIS/CrossPoint Screwdriver Blade $5.25

XPT-3-0 3.0 X 50mm JIS/CrossPoint Screwdriver Blade $4.85

LRSET Lens Ring Tool Set $17.95

TWZ-799-00 Plastic Tweezer $1.10

TWZ-808-00 Screw Holding Tweezer $7.25

OPTI-KIT Optivisor w/Light Kit 2.5X at 8" $53.95

I have the Nyogel #744 for everything other than helicals. The magic lube is the #10, HG-10, very expensive but the best Japanese synthetic, for helical threads.

Jim,

I'm going to cross-post your reply myself. Hoping to get a little more discussion on that "best grease" thread. I really thought this issue would have generated more interest around these parts.
