Brass Safety for 1377 and others

[FuzzyGrub]

I hate the plastic safety on my Prod and 1377.   So, after watching this video:



Decided to give it a shot.  I used a hack saw and file vs the dremel, and slighty different order of operations.

Here is the first one that went into the 1377:



Here is the original plastic with the new brass one:



If there is interest, I'll provide more details on the steps I used.

Let's see it!

I'm assuming the Crosman safety is the same across different models? I have a 2240 and Prod that I'd like to do the same to.

Here are the steps I did:

1- Cut brass rod to a little more than twice the length needed


2 - Chuck it in the drill and place drill in vice.


3 - Round the end with flat file.



4 - Mark the three grooves with sharpie.


5 - Using hack saw, holding steady, start each of the three groves.


6 - Continue cutting groves to correct depth, measuring with calipers. (think it was 0.150")


7 - Using the corner edge of the file, cut slight "V" in each of the three grooves.



8 - Mark with sharpie, the cut off length.

9 - With hacksaw, cut a groove for the cut-off.  Only a groove.

10 - Remove rod from drill, put in vice.


11- With sharpie, mark the deep flat position.


12 - Using the edge of the file, cut the deep flat.  Go slow until the groove is started.


13 - Use calipers to get depth correct.  It goes more than halfway thru rod.


14 - Mark the upper flat with sharpie.

15 - Using the edge of the file, cut the upper flat.  Go slow until the groove is started.


16 - Use calipers to get depth correct.  It's about the same depth as the grooves.

17 - Using flat file, cut the angle from the deep flat to the upper flat.


18 - Polish the flat areas by wrapping emery paper around file, use increasing grit to 600.


19 - Remount in drill, polish safety with 600 emery.



20 - Remove and place in vice.  Cut off the safety to length (groove from before).

21 - Remount in drill with protective tape.

22 - Round the end with flat file.


23 - Polish with 600 emery.

I found this on another forum. For those of you with machining skills, this may be helpful.

Updated with pictures from making the second one.  Probably too many pics! 

I apologize for some of the one handed pics, and that is not how you use a set of calipers!


Michael, thanks for the mechanical drawing.

or you can buy one for $10 on ebay: http://www.ebay.com/itm/Brass-Safety-pin-crosman-1377-1322-2240-2250-2289-2300-/330891435253?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D6314696216892922004%26pid%3D100011%26prg%3D1005%26rk%3D1%26sd%3D171001582508%26

Thanks for the great write-up, pics, and video. You added to my bag of tricks, and my shopping list (better calipers).

Very nice tutorial and good pics too.

if you like those metal barrel bands for 1377's and marauder pistol triggers too
i can find the machinist drawings for them too

You will find a multitude of things to measure with them, in the airgun hobby!  Mine is just a "value" one from Harbor Frieght.

Yes, I would.

Nice job and thanks for the write up with photos.

Yes Please!

Thanks for posting.

After reading this thread I ran out to the shop and whipped one up.
It is a nice improvement both in looks and the way it feels more positive when engaging/ disengaging the safety.

Glad it inspired you.  I installed the 2nd one in the Prod last night.  Works great, and looks even better!

Thanks for the write up and pictures. I was able to make a few for my guns this weekend and they turned out well. I modified them for left hand use by reversing the order of the shelves (grooves stayed the same), and added an additional groove on the "fire" side that I'll eventually paint white (or green?) for safety on.
