Title: Daisy 880 is Starting To Get Together !
Post by: wll2506 on November 28, 2018, 09:05:57 PM
Well, just got my Center Point 4x32 scope, and of all the Center Point scopes I have bought this one IS the lowest quality by far ... but .... for its intended purpose on this gun, it works ....
Why does it work IMHO... It is a very light scope and it is short, the physical dimensions fit the rifle very well. Yes the objective is not variable, but I can work with it. I would like to knock the parallax down from about 30yds to about 25. The scope cross hairs can be adjusted to be nicely in focus ... for me this scope works ... It also has a pretty good FOV ... MUCH better than the lesser expensive Tasco's for sure !

My Daisy parts arrive next week as does my GEO LDC and you will see a pic of that too. I will also take a pic of the piston head with the hole soldered up to make a flat head piston.

You can change the focus on most fixed scopes by unscrewing the front ring and then screwing the front lens in or out till you get it where you want it.  I have done several cheap scopes over the years.

Yes, I may give that a try, but the front end seems pretty cheap and I don't want to break anything ;' )

Got this for lubing the 880 and the other 880's I'm sure to get ;- ) ..... Under $4.00 ... Will probably last a few lifetimes ;- )

Your 880 looks great with that scope on it. As far as the “other 880’s your sure to get”.....
Yeah, I think 1 880 calls for another, or 2, or 3.....

They are very, very nice ...Will be putting one on my 880 very shortly as I'm waiting for my Daisy parts to come in so I can do all the things I want to do with one take down !

Trigger shim
Fill Piston Gap
901 mid barrel support

Got some stuff for my mods, decided soldering up the piston hole would be a PITA, so I'm going with the best JB Weld I could find.
Bottom pic is a 3/4" felt pad in the bottom of the cocking arm slot to help quiet down the arm slap when pumping.

Well I took this baby apart ... it is never as easy as watching the video of the guys that have done this 100's of times ;- ) Well  my 880 frame is not cut out like all the others I have seen ... a bummer for putting in the sear shim as I had to take the trigger out .. but I did it and it is a little better, but I needed more shim ... but I can live with what I did as it is about 15% better ;- )

I also took out the pump and put JB Weld in the piston head .... that will dry for about 20 hrs ---- Also added the 901 Barrel sleeve ;- )

I then attached GEO's LDC ...... Looks great ... you do nice work Geo ;-  )

Title: Daisy 880 is Together with Mods !
Post by: wll2506 on December 02, 2018, 12:07:09 PM
Well she is complete, but must get new safety from Daisy ;- (

1) Piston has hole filled with JB Weld.
2) Piston head has 2 layers of foil tape on head covering the JB Weld.
3) Trigger has been shimmed.
4) 901 barrel sleeve has been installed around straw barrel.
5) GEO LDC has been installed..

(https://photos.imageevent.com/wlleven/k10dtest/downloadphotos/880%20Shed%20sm.png)

I will Chrono it when I get home in about 2 hrs or so ... will do some preliminary sighting in also, just to get a feel. I'm hoping for around 575+fps with 7 pumps using Piranhas .... we will see ;- ) I did notice that pumping seemed to be harder, putting more air in chamber ;- )

I want this to be a usable, fast cocking (for a pump) HOSP, Starling, Pigeon, Rat gun at around the 25-35 yrd range. Assuming I do my part and hit the vitals !!

Title: Daisy 880 First Testing With Mods !
Post by: wll2506 on December 02, 2018, 04:01:38 PM

Well came home and started to chrno the build ... at first I was excited, but that quickly waned as speed dropped to ~475fps with 7-8 pumps ? I did not hear anything leaking but I still took the piston out ... the piston head was very corroded in goo .. which turned out to be the glue that is under the aluminum tape ... it was very bad .... I wiped it clean and put a few drops of 30wt-nd on the wiper and seals. I'm sure the stuff was in the barrel, valve and transfer ports as well. It took a while to "Blow it Out"

After about 20 shots it settled down ;- )

I'm getting about 30++fps more velocity then i was before. I'm still using 8 pumps as I did when I first got the gun. I was hoping for this speed with fewer pumps but so far that is not to be. I very well may limit the air volume in the chamber to increase pressure to see if that does anything .. I sure would like ~575-600 with 6 or seven pumps. I want a good velocity with the least amount of pumps available !!

Enclosed are the charts showing the two pellets i tested The Crosman Piranhas and the Crosman Heavy Copper. The Piranhas are nice closer range pellets giving a tad over 4fpe at 45 yds and close to 5fpe at 35 yds ( not shown). The Crosman heavy Copper plated are giving me close to 5fpe at 45 yds .... very happy with that.

i think velocity will climb a bit after i clean the barrel from all the glue and stuff that I'm sure is still in it.

I will find a way to add shim without the glue leaking out in the chamber.

If you guys have a thought on what to use, or what you used and had success with, please let me know.

Did you sand your piston flat after filling the hole?  If not, you're losing a lot to that groove around the edge.

Out of curiosity I tested my 880 a few minutes ago. I used 7 pumps and the 10.5 gr Piranhas.

1. 575 fps
2. 573 fps
3. 546 fps
4. 574 fps

I don't know what happened with the third shot. Maybe I miscounted pumps, or picked an undersized or overweight pellet?

So, I think your goal is possible, but you are going to need some more mods.

575 FPS with 10.5 gr pellets and seven pumps is great.

How many aluminum shims did you use over the JB weld fix ?

You're very welcome.

I didn't use any shims. I sanded it flat and then added a stainless steel washer behind the piston.

That sounds like a must do ... What size washer did you use .. I like this as it ads a lot more support to the piston and reduces the flex so more air gets to where it needs to go !!!

Mac, it not only look good but it takes the bark out of the shot when you pump 8-10 times, you still hear the shot, but a lot of the snap is gone, well worth the money, not to mention the barrel goes in snug so there is no slop and the need for taping the barrel is gone ;-  ) ... Geo did a very nice job. To tell you the truth I may order a couple more for other 880 projects i have in the works.

Wll - I'm not sure what size the washer is. I think it's a 1/4" washer. If you look closely at the picture I posted, it is slightly thinner and a smaller O.D. than the black Daisy washers that hold the rubber bumper.

Went to the hardware store and bought some #12 screw stainless washers after taking caliper readings, that is the perfect washer size ... I will install it tomorrow at work ;- ) I hope it is not a PITA job, it doesn't look like it, but you never know ?

The ONLY issue I have is the glue under the tin foil cover on the piston head is still slightly oozing out .. I need to find another adhesion material .. a .010-.020 shim might be the answer, but what type of glue, or maybe VHB double face tape may be the answer ?

I don't use any foil tape. The piston head contacts the valve and the rubber bumper compresses. Pump it slowly with the valve open and you can feel the piston make contact.

I also remove that coil spring that contacts the pump handle. I've never had the pump handle pop back out, and pumping is smoother and quieter.

I use a wood-working clamp to compress the piston enough to install the roll pin.

Hi Wil, it looks like you're making that 880 into a nice shooter. I shot one about 40 years ago and was impressed with how easy it was to pump.
Maybe I'll get one...

Don't know much about the piston or the gun, but I've had some experience with piston shimming.... and foil tape has never worked for me. I think that the combination of piston lube and condensed moisture releases the adhesive.. under high the pressure.. don't really know but it hasn't worked for me. I've have had good luck with JB Weld as follows:

Texture the face with 220 grit so the epoxy has a better surface to grip:
(https://i.imgur.com/Mqvjv7b.jpg)

Thin the epoxy with acetone or lacquer thinner so it can be poured (it won't affect the strength):
(https://i.imgur.com/3Pbh8bf.jpg)

Face the shim to the desired thickness (this one is .010") and "paint" with cyanoacrylate to seal the surface:
(https://i.imgur.com/2vekNwa.jpg)

I've done a P17, HW75, and (2) Fas 6004 this way and haven't had a problem with any of them (knock on wood)  ;D

That's a nice looking shooter you have... I'm starting to think that I "need" one  :D

Gary,

Thank you for the advice ... I just may do that .. the adhesive under the foil is oozing out over time. I was thinking of a metal shim and using JB  Weld to hold the piston head to the shim. Your idea sounds easier.

I assume you have no problem with the oil dissolving the JB weld ?

Title: Washer in Piston filling gap.
Post by: wll2506 on December 05, 2018, 11:43:56 AM
Put a washer shim in the piston assembly to hopefully limit some elastic spring movement .. We will see.
(https://photos.imageevent.com/wlleven/k10dtest/downloadphotos/Pump%20Head%20With%20added%20Shim%20sm.png)
I very well may take out the elastic spring and make that entire area solid, so there is no give, giving the pump full compression. I'm hoping this will increase air volume and pressure with less pumps but pumps would be harder as there will be no give.

I'm not trying to turn this 880 into a 800fps gun with 10.5 gr pellets, all I want is a velocity with 10.5's that will give me 5+fpe at 45 yds with 6-7 pumps if I can do that (It may take 8 ) .... about 585-625fps is what I need. If I get more, that is a plus, but I don't want to be pumping 9 + times.

No problem with the oil but on second thought, there may be a problem with the piston contacting the valve face (bulkhead). Mine were done on SSPs and I left approx. 0.010" clearance from the shim to the bulkhead. Essentially, it just took up volume and made a higher compression ratio.

So I don't know how well it will hold up under mechanical compression... should have connected those dots earlier. I like what you and bhh are doing to add preload to the piston bumper.

Post by: wll2506 on December 05, 2018, 06:58:38 PM
Well the speed went up a bit, but it may take getting rid of the elastomer spring and replacing it with solid washers ?

All velocities were with 9 pumps :

Crosman Piranhas 10.5gr-595 FPS
Crosman 10.6gr Copper Heavies- 585 FPS
Crosman Premier HP 7.9gr - 668 FPS

I wish this was with 7-8 pumps, but I may be asking to much !!!

The Copper Heavies and the CPHP’s give me 5 fps at 45 yds :-)     The Piranhas are almost there :-)

I might add that with 7 pumps, my 177 cal lead Gamo round balls at 8.2gr are shooting between 585-590ish fps ... giving me ~5fpe at 12 yds ... more than enough for a "Coup de Grace."  50 rounds loaded at all times is a huge plus in a hunting scenario.

I will try replacing the innards tomorrow and see if that gives me another 10+ FPS ... We will see :-)

I replaced the rubber bumper with a solid stack of washers in my big bore 880 project. I found out that the rest of the parts can't take the stress and wear quickly. This increased headspace and power went down.

Given that, I'm a fan of the rubber bumper as a means to keep from over-stressing the system and wearing out parts prematurely. But maybe you can find the stack to give you the perfect balance between power and longevity. It's fun to try.

You really need to port the valve, drill the transfer port, make an extended slim probe, increase hammer travel, and install a stiffer hammer spring. And sand the piston head flat.  I did one mod at a time and measured the improvement. Some were only single digit improvements, but they all add up.

When you took out the elastic bumper, how many times did you pump up the gun ... I'm looking at pumping no more than 7-8 times ... would this put extra wear on the parts ?  I'm trying to get 10 pump velocity using 7-8 pumps ... how much did the stiffer hammer spring help in FPS   5 fps ?

Good point about the number of pumps. I was going for max power and used 20+ pumps. I think you should try it and see how it works in your case.

I don't remember how much the hammer spring helped. Without it I would sometimes get valve lock.

I'm going to try to use the washers in place of the elastic spring .. and if I don't like that I will use Belleville washers, so I have a little give but not much ;-  )

I will NEVER use more than 10 pumps for sure ... I would like to use 7 to get the speed I want but it may be 8 or 9 pumps as the magic.number of pumps to get the speed I want.

I also took out the pump and put JB Weld in the piston head .... that will dry for about 20 hrs ---- Also added the 901 Barrel sleeve ;- )

I then attached GEO's LDC ...... Looks great ... you do nice work Geo ;-  )

And now for the bad news .... Yes the safety spring and ball went flying to China ... man alive was I &^#%&* OFF !!! This means I will be calling Daisy Monday and ordering some springs and detents ... but I will order some more stuff too so I wont need anything else for many years if I live that long ; - ).

Interesting thread! I'd like to know the number of your gun that's stamped into the barrel shroud, if you don't mind. I'm not sure if it'll be a "S/N", or a "LOT NO." or will say nothing as all these were used in the later years. But I've only seen one other valve body that was imprinted with a number (it was 170307) but it has the "window". I'm curious where the imprinted vs. plain and new style windowed vs. no window valve bodies fit into the scheme of things.

I just looked at the barrel shroud and found no markings other than the Daisy Powerline name, caliber and made in China markings ;- (

I purchased this gun maybe 3ish weeks ago at Walmart

That's very odd- I've never seen or heard of an unmarked 880 before. Usually on the newer guns there'll be a number more to the underside of the barrel shroud than on the side like in the photo.

But thanks for trying!

Wait, I was wrong ..... I have looked for the ser # before but could not find it as I had no idea where to look and second, I'm blind as a bat ;- ) Looking at your photos i went downstairs with a good light and found it ;- )

Wow- what an excellent photo!

Now, "16" shows up a lot. It is seen as the first 2 numbers on the model 880 as early as 2012 and quite possibly earlier. I've seen 16 on a model 25 pump gun and also on a model 35.

16 is followed by the year the gun was made, in your case 2017. The rest of the numbers probably break the date down further and no doubt the production sequence is in there too but so far I don't know what the code to it all is.

Thanks again, Mark

Thank you,Mark!
 You just told me how old my little 35 is, that my buddy got me from a yard sale. 2013!
  It now sports a "rifled" barrel. ;D 8)

A rifled model 35 sounds like a great combination, I have to say.

I'm still trying to sort out the dating schemed Daisy used. There's one document that tells part of the story of the convoluted Daisy numbering "system" but it was compiled sometime in the early '90s, I'm guessing. It's HERE (http://www.network54.com/Forum/576299/message/1379141967/The+Daisy+Numbering+system). Also the Daisy museum has a form you can fill out and mail to them to get info (form HERE (http://www.daisymuseum.com/knowmore.aspx)).

The number Daisy first used was the Register Number, or “REG. NO.”. The REG. NO. was a letter followed by six numbers on most guns (the No. 25 briefly used a number without any letter prefix).

Beginning late 1972 the REG. NO. was formatted to let anyone knowing how, to decipher the year and month the gun was "made" (actually it was the date the gun was stamped, actual production could lag behind when it was stamped). Letters A through M (less “I”) was the month, the first number was the last number of the year, he remaining five numbers were the production sequence. The REG. NO. stayed in use until sometime in the mid-'70s when it was changed to a “LOT NO.” which started out using the same "One letter prefix followed by Six numbers" date/production sequence number as before. This code lasted until approximately 1982 when it was changed to One digit (year)>One letter (month)>Five digits (production sequence). Then in about 1993 it was changed again, this time to Two digits (year)>One letter (month)>Five digits (production sequence). Since then it has changed several more times but I haven't pinned down the dates as closely on the late model guns as I have the earlier guns. At first glance all these changes seem to make no sense, but considering the 880 has been in production since 1972, if they didn't change things at least about once every ten years it would get hard to tell the years apart.

I often read that "I" wasn't used by Daisy as a LOT or REG. NO. prefix. The way I'm seeing it shake out is, "I" WAS used as a prefix before Daisy changed the numbers along about 1972 to allow anyone knowing the 'code' to decipher the year and month the gun was made. No doubt the thought was that “I” could be mistaken for the number “1”. So up until 1972 “I” was used, after ’72 “I” was not used.

The following is what I have on the Daisy 880. I suspect other models will be close to this but the exact changeover dates may well be different. From 1993 on, I need a lot more samples.

•   One letter>Six digits changed to One digit>One letter>Five digits
  o   1982 Sept. LOT NO. J202705
  o   1984 April  LOT NO 4D08949 (this should eventually be shown to have begun late 1982)
•   One digit>One letter>Five digits changed to Two digits>One letter>Five digits
  o   1992 Aug., 20th Anniversary 880 LOT NO. 2H03196
  o   1992 Dec. LOT NO. 92M15985 (NOT a 20th Anniversary model)
•   Two digits>One letter>Five digits changed to Four digits>Space>Five digits
  o   1993 Oct., LOT NO. 93K02596
  o   1995 Aug. LOT NO. 0895 03612 (this should eventually be shown to have begun 0194 xxxxx)
•   LOT NO. Four digits>Space>Five digits changed to S/N Twelve digits>One letter
  o   2006 Oct. LOT NO. 1006 12227
  o   2013 April S/N 162012430204Q

ETA- Thanks to all the fine folks here who volunteered info on their 880s. Sometime soon I hope to post a lot more info on the various changes made to the 880 and when the changes were made. Without their help none of this would be possible so again- thank you!

They should make that last post a "Sticky".

While this gun is getting together I'm buying a few used 880 parts off ebay cheap !! ... just bought a bunch of new style 880 parts for ~$14.00 shipped. Includes the heart and lung parts and extras .. can definitely come in handy if I buy a beat up 880 that is not working !

Not buying off the ripoff rats, but folks that are just selling old stuff to get rid of. I bid supper low as I know and they know there are very few folks that want this stuff, and they may not sell it. I offer super low bottom, if I want to come up if they turn me down I can, but if the price comes anywhere near what Daisy sells parts for, they can pound sand !!
