And finally... I used hot glue and propoxy to plug the bb track to the breech to keep pellets from falling down the rabbit hole. I also used hot glue to fix the the bb loading door in place. How many times have you had to close this thing after pumping? We won't be putting any bbs in there anyways.

Put it all back together and I'm pretty impressed with the results. Gonna get back in and do a bit of tweaking on the trigger until the magic one from Stony arrives. Also, on both the 881 and Ted the pivot pin in the pump arm wants to wander back and forth causing it to rub when pumping. I'm gonna ping them in place or use a bit locktite or superglue to keep them in place.
Oh yeah, one other thing....
All three of these gun, including Betty Lou's M/M 880 seem to love the Winchester Dome pellets. The pellet opening in the breech on the Ted and 881 needs to be ground a bit larger for the Winnies to slip in without risking distortion of the pellet by forcing it in. I also pop the butt plates off and fill the stocks with silicon for weight and balance. I pumped a whole tube into each. Really gives them some heft and they feel like a quality rifle.

So there it is. New 880 guts in a couple worn out Metal/Metal Daisy pumpers. I'll get some chrony results and post them after the tweaking. I'm sure some of you have other ideas, mods and procedures. Please feel free to add to the thread. It's all about sharing knowledge and experience.

I did all of Stony's suggestions to a new 880. Taping the barrel, tweaking the trigger,filling the stock. It now has the little Tasco 2-7 on it from Wally world(something like $17 as I remember) and I am quite happy.
Those little fluorescent stickers you see at yard sales? about 5/8 " diameter. Nailing them easy 25-30 yards.
But what I really like to do... shoot a hole in a blank paper. Now use that hole for the bullseye.
Bigger bullseyes throw me a little so I like trying to stack pellets. These 880's will do it!

nice work the new/old 880. i owned mine for almost a year and have now made an all metal and wood 880 I love it. also looking to put wood furnishing on my 922 soon. metal receivers on an 880 are the dream add wood and it feels golden. I have several metal receivers and yes that are all different in how they need to fit in new internals. i see that you have done a few of these, is there a size difference in the valve chamber volume from new to old and what has seamed to work better for you.

Great thread Bill, thanks for taking the time to put this together!

Betty Lou is Brilliant!! Not to mention I would trade 5 turkeys for a Ham any day!

Now, when did they make wood 880's?
I ask because I thought I had one of the first ones... I've done my Gazindas and come up with 1975 when I got mine. It was plastic, I know this because the stock broke at the receiver after about 100,000,000 pumps and I was heart-broke, turned me against plastic guns for about 4 decades. Didn't want another until I read here on GTA they were made of wood at some point.
I am pretty sure of the dates because Dad had just built our house in the country in '76 and I know I had the Daisy towards the end when we lived in town...
The good thing about the 880 breaking was that's how I was able get my 342.

airgunner53 · « **Reply #25 on:** November 26, 2016, 05:01:18 PM »

they made a few runs of the wood stock 880's they only ran for about 3 years each time. i bought the parts and used them to mod a new 880 internals into old parts.

That's awesome.. some nice wood would make these old guns the complete package. The only clearing of metal I had to do on these two sample is what I mentioned above.
I went back into the Ted and did some trigger work. I took just a tad of metal off of the sear block and a touch off of the trigger where it hooks up to the sear block. Then I polished all contacting point with a brass wire attachment on the dremel. I put some moly paste on all these locations and packed some in the holes the pivot pins go thru. This moved the break right up to the front of the trigger pull just how I like my triggers. No creep at all yet the pull is strong enough not to feel unsafe. The safety still works.
Then I looked at the pump handle linkage where the connecting link that connects the handle to the pump piston connects to the pump handle. There is a hard plastic bushing in there that the pivot pin pushes into. It's supposed to fit tight enough not to let the pin work side to side. The plastic bushing was cracked allowing the pivot pin to drift in and out in both directions. I found a piece of nylon HP air line (red) with the ID really snug to the pivot pin diameter. I cut that to a snug length and replaced the plastic bushing. So far the pin hasn't drifted at all.
Then I opened the breech opening so a winnie dome pellet would chamber without any force that would distort the pellet.
I'm happy to report that paintballs at 35 - 40 yrds are automatic with 5 pumps. If you haven't ever hit a paintball with a pellet gun you don't know what your missing. They "SNAP" almost as loud as the crack of the gun firing and send a visual splatter in all directions. Different colors provide some pretty abstract art on the backdrop of choice. We took a 6' 2x4 and drilled 16 3/8" pockets in the 4" side so the paintballs sit without rolling if the wood is struck. Then we numbered the front edge with a sharpie from 1 to 8 and 8 back to 1. Many different game senarios can be played on this. I get my scuba tank filled at our local paintball field for our PCP guns. The owner always seems to have a bag or 2 of paintballs around that he says are no good to shoot because then break open in the guns. Too soft I guess, I'm not a paint baller. Anyhow he saves and gives them to me. The only problem now is forcing ourselves to stop shooting early enough to get enough sleep for the next workday.

after looking over your mod i looked back into my pellet gun and realized that I had not properly cleared all the metal and it was causing a snag on the bb load port and I removed it just as you did. while I was in there I redid my trigger to be short and break easy. I had to install a bot to make it work as my safety would not engage the new style trigger for some reason. also if you use the transfer port seal from the old valve and install it on the new valve, it will allow for the air to exit faster and reduce the resistance to flow. in addition the old transfer port seal has a weaker spring that will allow for a less resistance on the hammer spring. so a combination of old and new creates the perfect 880.

good work on your modification, i learned where i went wrong on my two halves and will be more attentive on my future daisy builds.

Great job and good info Oscar. One other thing I forgot. There are two nibs on each of the clamshells that line up with the two pivot pins in the trigger group. On the Ted I had a choice. I could either take a bit of length off of the nibs or use the pivot pins from the original trigger group as they must be a bit shorter. I didn't do this with the 881. The more I found out about the Ted, the more I think I need to get back into the the 881 and recheck a few of these things.

airgunner53 · « **Reply #29 on:** November 27, 2016, 08:11:17 PM »

good point bill, I also noticed the shorter pins and simply ground down the newer ones to match the ones that were in my 922. looking foreword to building my own wood stocks maybe a thumb hole stock, always wanted one of those.

Thanks for posting this. A while back I asked about doing such a surgery and no one seemed to know anything about it. Next time we head north I'll have to pick up an 880 to bring back. They're well north of US $100 down here. There are a couple of old 880's laying around wishing they had the guts to get to work again.

My first "rifle" was an old 880 (new at the time) that I wore out, rebuilt and wore out again. I could hit what about anything I could see with that gun, with anything from 2 pumps up to 10.

Every time I think about getting a 397, I poke around in the Daisy gate. Yup, pretty stoked about this thread. When I was a young teen, I graduated from a 760 to the 880- all metal- but it got tossed by my folks sometime while I was in the Navy.

This thread made up my mind.

There's room for both in a well stocked air gun locker.

Right now I've got the bare bones 880, but lack the 397 in any form or the 760 either. But it's the 880 that keeps singing to me from the past. There are a lot of memories wrapped up in that old bundle of parts. A lot of time spent roaming the wilds of the Amazon basin and the outskirts of town. Time spent with my brother and cousin. Birds and other critters that fell to a well placed shot. Yep, will DEFINITELY have to try one of these frankenbuilds.

After the Ted Williams was finished, I went back into the 881 to change a few things that I learned with the TW. Monday evening Betty Lou and I gathered in the outdoor 35yd range to continue our routine competition. We shot 5 rounds of 5 each beer cans off the 3" drywall screws, 3 each flippers plus the knockdown and 8 each paintballs. I'm happy to report, the 881 beat her M/M 880 5 out of 5 games. Betty Lou? Not so happy. She insisted that she was having a bad night. I've had those too but hers was REALLY bad. My wins were very marginal. It was so worth having McDonalds for dinner. I guess she just didn't feel like cooking. I do hope she feels better soon.

Naaa.... I still got Hardees, Zaxby's, Burger King, Pizza Hut and various others to go thru before I get real hungry. Do you know how good Ramen Noodles taste with the right seasoning and hot sauce? Some of them little round crackers and a PB&J. I am living proof that man can survive on peanut butter and Miller Lite.
