Removing staff from vernier sight

I have a Pedersoli Sharps with a Pedersoli long range soule sight. You cannot put a ramrod down the barrel as the sight is in the way (I wipe with a delrin rod which does have enough flex). Thought I would remove the staff by taking out the screw and knurled nut, and that would do the job, but I could not get the staff back on the base without removing the staff adjusting spring and to get that back in alignment is a task in itself. 
How do you fellows approach this? I know I can turn the gun upside down and clean from the muzzle but there are times I would prefer to transport without the sight on the gun. 
Sort of the same question for my MVA vernier. I bought an extra base so I could swap the staff between guns. When I do this I am always afraid that I will bend something when trying to mount it. The lady I spoke to at MVA said to just push down on it so thats what I do. Are there any tricks or methods I am unaware of? 
I did try to find this topic in the search function but without success.

Thank you for any information.

You could install a Goodwin sight. Depending upon how much you "wanna" spend:

On any vernier tang sight it helps if the staff is in the upright notch, as that unloads the detent spring slightly. Then you can push down on the staff while maintaining the position, and the screw will come out.
Going back is the opposite. Put the staff in and locate the dent notch, and then push down as you insert the screw.

I take my MVA sight off every time and use it on a couple of rifles.  I follow the recommendation to have it vertical and push straight down to ease removal and installation. My Hellman sight requires that I loosen the upper screw to relieve the tension or I canít even turn the screw which has a much smaller head than the MVA

Not quite sure what you mean about the Delrin rod. I do all bore cleaning with Delrin rods. Bend around the staff easy, if they wonít bend enough use a smaller Diamater rod. Smaller than bore diameter bronze brush run on a flexible rod wrapped in a oiled patch cleans as good as necessary for me.

Am very fussy about the staff absolutely perpendicular to the front sight, if itís off just a bit rear arpeture appears fuzzy. I can remove and replace staffs by pushing against the spring but it takes some fiddling to get it right. Easier to not remove it.

My old arthritic hands are not steady enough to compress the spring and turn the knurled-screw at the same time.† 

Small piece on wood or plastic on top of the spring near the pivot point, compress the spring and voilŗ!

Thanks for all the replies. I will approach it with renewed energy today. 
Ray, I guess I don't want to buy another sight at this time but that is always a fallback. 
Marlinguy, I understand what you are saying. On this particular unit the fit of the staff into the base is so tight it is difficult to move it around and get to the position required. Thought about stoning the inside of the base where the staff fits but will leave that alone for now. Dont want a sloppy fit there either. 
Jack, thats what MVA said as well as Marlinguy. I think thats the way its supposed to work. 
Boats, I like to clean with a heavier rod that has a chamber protector (drilled out cartridge) on the end. My delrin rod has a milled jag on the end so I don't have the option of using diff jags or brushes etc. 
For general information,the Pedersoli sight I have, a 406 long range I believe, has notches on the base and spring so perfect adjustment is just not possible. In order to engage a notch, I am either a tiny bit forward or rearward of true perpendicular. Not so much that it effects viewing thru the eyepiece though. 
Cajun Rebel, Thanks. I still have some strength in my hands but will surely note the idea of using clamps. 
What a great forum. Thank you all.

I don't use a guide or any chamber insert with my delrin rod, so it easily gets past my tang sights. Mine had a brass end on both ends, so I keep a nylon bristle brush on one end, and a cotton swab on the other. Depending on what gun, or powder I'm using it can be just reversed for what I need. If I'm wiping after each shot with BP I take the nylon brush off and install a jag that I push my bore wipers through with. Then turn it around and follow with a dry patch over the cotton swab to remove any residual moisture from my bore wipers.

Can you slide the rod between the rails of the sight ladder? That's what I do, and it saves a lot of time. I found a plastic thing at a hardware store that protects the rod and the sight. Can post of photo if you would like. Joe S

A friend of mine told me he was having the same problem,  when I looked at it the base was on backwards having the staff higher up the tang, took it off turned the base around ,reattached the staff,voila ,fixed.

Marlinguy, I like that idea and think I will pursue it. 
Thanks,

Joe, There is just not enough room to clean going thru the staff. 
Hiwall, I will be looking again in the morning to see if that has anything to do with my situation. 
Thanks for all the ideas.

Hi John,,
I assume what you mean is that the opening between the vertical rails of the staff is too narrow for the cleaning rod. If that is the case, getting a different cleaning rod might be an inexpensive solution. I always use a Tipton for the highwall but a Dewey would work just as well. 
Just an idea.

Joe

I have made Delrin rods from. 1/4 inch to 1/2 inch, & could easily make larger, covers everything except .22   3/8 & up drilled and tapped for jags. 

Delrin takes threads well, no doubt lot of removing and replacing would wear the thread out. If so cut the threaded end off re-D &T . One I use for 38/55 Has a worn out 38/357 wire brush one end turned into the blank jag groves other end. Oiled patch wraps tight around the brush & gives the right patch fit.

Used to make fancy wood handles lately use 1 inch Delrin knurled & locked to the blank with a dowel pin. Quick and easy.

You could make a business out of cleaning rods except the shipping cost would be very high. Material is inexpensive 10 foot blank makes 3 rods.

If shooting smokeless I don't clean until I'm done for the day and leave the range. But with BP I wipe after each shot, and if I couldn't do that without removing the sight, I couldn't shoot at all. It would be far too convoluted, and slow, so I'd be out of any match I tried to shoot in.
