Finger Ejector-id=640.png 87.42KB
Here is an idea for a finger ejector. This is taken from Nightman's drawing. I do not have dimensions yet. I have not made one yet. There is enough space to make this. It should work.

Finger Ejector, another view-id=641.png 117.02KB
Hey Mr. P,
I left the remaining lips of the ejector on the drawing for several reasons. The discussion of blow out is still ongoing. The idea of not modifying the previous or following part. Matching this idea with others. No dimensions. No testing.
I know that the barrel ring will have to be modified to accept the finger ejector but it's finial shape needs to be determined. It would be easier if the finger end was round.
I am planning on making the test prototype of the bolt with added material so that the remaining lips would be much more substantial and then removing material instead of adding.
What do you think of the belleville spring idea? I think a combination of the two ideas will solve the ejection problem?
There is also the flat spring idea.
I am getting close to finishing my other project. Then I can work on the ggun again. I think I am going to use the parts I have made for experimenting and make a completely new gun. I am on a fixed income so material cost is a big consideration.
Good to have Sparky, Roller and others with their ideas.

If the chamber is nicely polished and the 'finger' has a nice crisp hook on it, I'd imagine the Belleville washer could be done without.
I'm hoping when I've got my receiver finished I won't have any problems. Lol. Machining grooves in the bolts to add this finger is an easy fix though!

I know it would be a PITA but the "proper" way to implement a extractor as drawn would be to get rid of the original DE extractor hook (if its not broke off already LOL) and just go with the new extractor. Unfortunately, the barrell ring would have to be redone and the groove in the barrells to restore chamber support, possibly another method .
My plan, which is more involved, is to make extractors as drawn above, just like nearly every gun commercial made uses. I used ruger 10-22 barrels on my gun, which are chambered for long rifles of course, so I can put the barrells back in the lathe and square off the end to remove the existing cutout for the original DE extractor hook, chamber will still long enough for 22 shorts. The finished barrels would be maybe 50 thou shorter but who is going to notice that? THEN... I plan on remaking the barrell ring and going to a wedge clamp arrangemet for holding the barrells that was detailed in another thread on here.
I know its more work, but the finished product would have a fully supported chamber, good extractors, interchangeable/removable barrels and............... WORK..... the most important thing LOL
The extractor drawn above is the best solution. It is what nearly every gun manufacturer uses, because it works well. The RG gun uses this method and does not have extraction issues. If done in a initial build I think its even easier than cutting the DE extractor hook.

I just made a drawing of the idea you and Nitewatchman posted. I do not have any dimensions. I left the remaining tips for now for the reasons mentioned.
I see a problem with the proportions of the drawing. I do not think there will be enough material on the bolt to accept the retaining pin as the D&E bolt is smaller than the RG&G. It will interfere with the firing pin. Need to make one and test it.
