Ronno's Daisy Trigger Mod Install "Pic Heavy"

[Back_Roads]

 This is big for Daisy shooters for sure, hope this proceeds along with out many more snags. Ronno put me down for one you get to MFG.

Here's a short video of the trigger pull with the mod. I'm going to install a fresh trigger with it, instead of sanded down one, and I think it should give me a little more travel.

Parts on order for trial run.............

It has been determined that this mod, in its current form, is not suitable for those super-early
880/881's  that did NOT have the flat spring.
The cavity in which the wedge and spring are placed is way too shallow ........
This will not permit the original spring to be installed without binding.
However, as this is an extreme minority of 880's etc. out there, i am not overly concerned.

 My old ones do just fine, must be years of shooting, and I would not want to do this to a rarer model for reasons of originality.
 Is there a specific year to draw the line for those wanting a great trigger ?

I am not up on what years used the round exhaust valve and no flat spring.
Probably the same ones that used the real funky chamber seal and the plastic pump handle retainer....
From the inception of the 880 (1971 ??) til ....

I got a fresh trigger installed yesterday with Ronno's mod.

To recap, previously I was using my modified trigger with Ronno's mod, and it was way too light. My trigger had been sanded down, so when that was combined with Ronno's mod it was really delicate. Some might prefer that, but I wanted to have a little more travel.

I'm getting pretty fast at the swaps, I can get things changed over and re-assembled in a few minutes now.

So I installed the unmodified trigger and gave it another shot. It's great, I like having more travel. I think I want a slightly stronger spring, so I might play around with some different options from McMaster-Carr. Once I find the right spring, I'm going to prefer this setup over the sanded down trigger mod. I want something that's lighter than the stock trigger spring but heavier than the current one I have installed. Maybe like halfway between.

 Did some digging came up with

 My guess is 1985 and newer

Well, the clamp-on barrel ended in '82, and I have several of those w/flat springs.
My guess is more like 1975 when the lever retention changed to the rear spring-loaded latch.
Mark (cobalt327) may have a better handle on things.....

That's a good situation to be in.
It will be easy to make the pull a bit heavier.
Either a heavier spring, or a longer one of the same construction.

Kinda like making a board shorter...easier than making it longer........

Anyway, it will possibly be an installer-selected option.

[martis880]

That's a good situation to be in.

I agree!

Ragboat's Daisy 880 sear pix.
Sharkfin is most noticeable difference.
Top sear in pic 1 is old style;
Right sear in photo 2 is old style

The fin prohibits the sear from opening the valve completely.
Notching the sear to allow better opening renders cocking difficult.

The difference is between U.S.made sears and those made overseas.
THey have the same part #, but are NOT interchangeable.........

I was able to modify a IU.S.made sear by grinding off the little platform just ahead of the shark fin.
That allowed an increase in travel to open the exhaust valve.
Worked flawlessly in a Model 35.

I have just took delivery of (4) Ronno6 Daisy trigger kits! Have a flock of Daisy pampers that need GOOD triggers...and hopefully a Daisy 901 on the way soon.

First to get a "kit" is my Daisy 35, it's less than 6 weeks old. The kit was easy to install, and I got it installed on the same evening the kits came in the mail.

   Results:..... Amazing!!
I have borrowed my brothers RCBS trigger guage the day After I did the trigger, so I did not get a "before" weight, but it is now only a 10 OUNCE trigger! Every thing else is stock and this Daisy 35 has about 300 rounds thru it so it is starting to smooth up some, but the only thing I did while I was inside besides the kit install is I found a little drop of clean Daisy grease (stuck to inside of receiver) and I scooped that up with a toothpick and added it to the trigger sear engagement, but it was not dry from the factory. Also I did the "tape mod" to the barrel while I was in there.
   I need to zero my new AO scope and do some shooting, but I did test fire after kit install with both 10 and 15 pumps, and the 35 is dumping 100% of its air, so it seems the kits are rock solid on a Daisy 35.
   I will put a bunch of rounds thru it Sunday if it's not raining here.
   The Next gun to get a kit is my 880, I will report back as all the Daisy triggers get fixed by Ronno's kit.

Side Note:

I did absolutely believe the 10oz number the RCBS gauge gave me, however as this is not my personal trigger gauge, I did measure my stock 880 trigger and got 6.25lb and my New 1977xs measured 7.2 lb

Here is a photo of the trigger gauge I used.
   I think this kit more typically gives a 1 to 1.5 lb trigger pull, not sure why my 35 gave me 10 ounces, but you sure will not catch me complaining!

Trigger kits are now available in the Hobbyist Classifieds Gate

 My lucky day , ordered 2, as I have a couple more 880s to sweeten up with this trigger.

There are 2 important points which I must touch upon:

1. Installation of the 880 Trigger Mod pretty much necessitates the elimination of the flat spring.
    That shouldn't be a big deal as it is always the first thing to be removed when attempting to improve the trigger.
    I just thought I had better mention it...

2. VERY EARLY 880's that do NOT have the flat springs cannot use the Mod Kit in its present form.
    If original, these will have round screw in exhaust valves. There is not sufficient depth in the cavity in the
    valve body for the new sear valve spring.

Hopefully, these things don't interfere with anyone's plans to improve their triggers.....

This kit will work on: Daisy 880,881,822,882,901,917,920,970,922,920,177X,22X, 22SG,35 and I believe on the 1910 BSA rifle.
                               Winchester 977XS and 1977XS

There may be others..............

[Ronno6]

Here are the 2 valves with regard to the flat spring:


The one on the left had the flat spring; the trigger mod fits this style
The valve on the right never had the flat spring; the mod will mot work on this valve.

[Hunterdude]

I strongly suspect the kit will also fit the Daisy 2840, from my understanding the 2840 IS a 1910 BSA with a camo stock and the BSA emblem removed.
   I was inside a 1910 BSA and it looks exactly like a Daisy 35....only a (single-pump) model.
   That's quite a list of Daisy airguns, I am going to have to Google some of those other models to see what they are.
