Daisy 880 etc. Oil Wiper

[Ronno6]

As Daisy's parts woes continue, I am searching for a replacement for the foam oil wiper used in the 880 and many other rifles.
I have been punching them out of polyurethane foam. but the concentricity and squareness have been inconsistent.
I need these for my Old Style 880 seal conversion kits.

These wipers used to be made out of felt.......I have seen some which have lasted for years.....
The felt does not disintegrate like the foam washers.
Daisy probably changed material for cost reasons.
I am exploring furnishing felt washers intended for use with oil.

Does anybody have opinions on whether felt would be better or worse for this application?

I don't have personal experience nor do I have scientific backing to my opinion, but I would guess your assumption regarding the older style felt wipers being exchanged for foam in pursuit of lowering costs is probably not far off. If you've seen old felt wipers hold up over time, I see no reason they could not be used again as long as you find the same material, or at lease a suitable modern equivalent.

I guess my only concern would be fibers coming off the wiper and crossing the piston sealing surfaces, or getting to the valve or something to that affect. I don't know if this is a realistic concern, just my initial thoughts.

[Ronno6]

Stray fiber contamination had crossed my mind, but I guess we'll just have to try them and see.
I nave not located washers with the proper ID and OD needed; I can find 1 or the other.
So, I am trying both.
Punching a larger hole in ones with the proper OD will give a cleaner, more lint-free edge, but will be harder to keep concentric.
Resizing an OD will be easier, but may have more stray fibers.
I won't know til I try, and the search continues...........

 I had suggested this to Stony a long while ago, and it worked for him! 
 If you have an old pair of felt liners that you are replacing in your winter boots, cut felt washers from the tops of those liners before tossing.
 The tops are usually in great shape, and the "washers" are about the right thickness.



for foam, buy a cheap foam roller paint brush and you may be able to make one from that material. Needs to be porous.

Winter boots??? What are those??
In South Mississippi, winter boots means wearing socks with our flip-flops.........

I have found felt was hers of the proper thickness from McMaster Carr.
They are intended for oil absorbing/lubricating purposes.......material should be fine, if I can get the holes right.
And the felt shouldn't easily tear....

Wool felt wipers/oilers can last practically forever. Don’t think I’d worry about loose fibers. Don’t think they’ll get past the o-rings. I’d be inclined to buy F-5 sheet felt in the proper thickness and use a couple piloted punches to ensure concentricity.

[Ronno6]

I'll see how these washers work out.
I will buy the sheet felt if things look good.
I have the correct size punches and I made a concentricity button, which usually
yields one side pretty good, but the material can drift a bit on the other side.
Sharpening the punches didn't seem to help.
I am cautioning customers to install with the concentric side towards the piston.
As long as the wiper enters the pump tube without snagging on the tube lip, it won't much matter what the trailing edge does.

Haha! Did not consider that....    up here we have Sorel Pack Boots... rubber bottoms, leather tops, with a removable felt liner. Wool soles always wear out before the tops..
 socks and flip flops.. can't unsee that!
