Old Slide - New Sights

[schmeky]

First pic is a Sine vise, which is used to establish ultra precise angles.  This customer had a very old 75 slide and wanted tritium night sights installed front and rear.  Problem is the rear is the old BRNO narrow cut of .348" (newer CZ's use a .384" cut).  Since it is much more expensive to cut the slide, we opted to cut the Mepro-Lite rear to approximate the BRNO cut, thus saving the customer some money.  Here is the sight set up with the proper angle prior to milling to make it fit perfectly in this old slide.


Here is the sight immediately after the cut, fitted in the slide.  Looks really good and is a super snug fit.


Another pic:

Now for the front.  This is a Dawson tritium front sight and we did the math to make certain the sights are properly regulated.  This uses our CGW method for positively retaining the front bushing.   This sight cut in perfectly, no light between the bottom of the sight blade and top of the slide.  Man, this is fun!!!

That sir,  is truly amazing precision work.
Sine,  as in sine-cosine?

Man! I really like this! I would love to see more details of how you are doing the front sight. This is the one thing that has kept me from buying any of the older guns. That is a great looking job! If it is not too much trouble please take some shots before the front sight is installed and especially if you are installing a 10X bushing with the sight.

1SOW,

Yes, as in:

sin = opposite
        hypotenuse

cos = adjacent
         hypotenuse

SP01SHADOW,

We'll take some pics on another project in the near future to detail the retention of the bushing.  It's really quite simple and effective.

David,

Are there other sights that can be adapted to the old dovetail cut? For example, your EZ/D sight?

afultz075,

Yes sir, can do quite a bit with the older slides.

This is something I would be interested in having done.  How do I contact you for further information. Thanks
