Haven't checked in here in a long time. Greetings to all the
regulars. I've got a Vivitar cicular polarizer (77 mm) stuck to a
Firecrest IRND 18 sunfilter (77 mm). They seem to have become welded
together. Any advise on how to get them apart? Tried putting on some
heavy duty latex surgical gloves and seeing if that would give me a
better grip, but no use. Any suggestions?.

It sounds as if you are in need of a filter wrench of the appropriate
size.
Available at B&H, or Amazon.

I think I'm going to invest in one. Finally got them unstuck. After
I had them inside for a couple of hours warming they loosened up.
Arthritis in my fingers, particularly my thumbs, makes these things
much harder than they used to be.

I once used a plumber's pipe wrench on a filter stuck on a lens. I
mounted the lens in the workshop bench vise.
Fortunately it was a filter I didn't care about. And while I cared about
the lens, it was a common one and not too expensive.

Interesting approach!

the real thing is less than usd 2:

Right, and if you want to wait for a few weeks for it to arrive from
China, it's a good deal. Estimated delivery is between November 21st
and December 26th.

Adorama will get it to you faster, but they add shipping charges so
the total price is about $6.00.

I'd try the "hare-brained" methods first, though. I have one of those
rubber strap wrenches that does not harm what it's used on, and it
applies even pressure. First, though, heat it up with my wife's hair
dryer.

While I wouldn't begrudge the $2 or $6 expense, or even the delay in
getting the item if I had other lenses to work with, I don't need
another one-time tool around. I doubt if a second filter will turn
out to need wrenching.

I do not believe any of the hare-brained schemes are a good idea, unless you
have no regard for the filters, and/or lens.

Even though my strongest recommendation was to buy the filter wrenches from
B&H, Adorama, Amazon, or the photo store of your choosing. I have not yet had
the need to do that, as I have always had nylon cable ties handy, and I have
only had the problem twice some years ago. In both cases the improvised cable
tie wrench has worked perfectly, and those are available at all hardware, and
auto parts stores, and Walmart.

These days I take care in attaching filters making sure I don’t over
tighten, but if I do screw up, I always have those cable ties handy.

Soo... You'd risk them rubber gaskets in a USD 1K+ weather sealed lense
by overheating them just to save a few bucks... :-)) Should go into lens
MF. Cathingcathing!

If I had a UD $1,000 lens, I wouldn't be using a Vivitar filter on it.

I was thinking the same thing. Budget quality, aluminum frame filters are the
most susceptible to binding. That said not all aluminum construction filters
have the problem. It is a case of paying for that little extra bit of
quality, in materials, and construction. It is worth noting that even with
the better filter brands there are different quality grades.

If they get stuck once then they will probably get stuck again... You
could use some lube on the threads but be careful though not to overdo it
so that you get smear all over your gear every time you get near the
front of said lense!

the solution is to buy quality filters.

not only do they not bind, but they don't ruin the quality of the
photos.

Brass is better than aluminum but high quality composite would not stuck
that easy either. Could be a good alternative if they hold shape. Any
ring can get stuck though:

Got them unstuck. I think they simply warmed up after a while after
brining them inside and finally let go. Arthritis in my fingers make
these things more difficult that they used to be.

Well, I thought to add in my original post that the vivitar filter was
probably the first mistake, so point taken.

3 point grip helps, sometimes. Thumb and two fingers. That way thr
filter doesn't distort so baddly.

Thanks. Good to know.

Just go with a filter wrench, that is what they are designed for, and forget
the hare-brained schemes.


Noted.

Yep.
The only filters I now use a ND; variable ND; CP; and a variable fog.
I carry filter wrenches in my bag at all times, although I haven't had a
stuck filter in over ten years.

When it comes to screw on filters I have ND, CPF, and only one Variable ND. I
have not been impressed with the variable ND, and it doesn’t get that much
use. Most recently I bought a few of the Hoya Solas IRND filters.

I use the screw on filters for those times it is inconvenient to use the Lee
ND and ND Grad system. The Lee system also includes a pretty good CPF. I use
the Lee Seven5 system with my Fujifilm X-cameras.

Thanks for the tips. I'm going to look into these.

The variable ND allows me to compose without having to attach the filter
later. I only use the fixed ND when it is very bright. It is a ten stop.
In another post I mentioned that I was advised by B&H not to purchase an
item. It was any of the Lee type filters. I had wanted to get a
graduated ND filter. Watchagonnado.
