Rear sight
These pics and videos show how I finished the rear sight.
The rear sight is a little more challenging then anything else on this build.
The size alone makes it tough!

 |
|
This is what I started with. Found a piece in the scrap bin that was close to the size that I needed plus would give me some extra if I needed it. |
The first step I took was to mill my block to the over all height the sight would be in the laid down position. |
The short distance tang
 |
|
| Getting ready to cut the profile for the short distance tang. |
Here you can see the tang for the sight when its in the lowed position |
The next step I machined the step and long distance tang
|
|
|
|
I don't have a very good pic of this step. Not sure what happend. |
Just another bad pic of this step. Sorry! |
Next I drilled and tapped the wind age adjustment hole
|
|
|
|
Getting ready to center drill. |
Drilled and tapped. 4-40 tap |
|
Here is a 45 sec video of this step for your viewing pleasure! |
Next step mill the long distance tang opening
|
|
|
|
I plunge drilled then cut the opening in one pass. |
All done |
Next step was to notch the short distance tang and then this portion of the sight
would be complete. No pics or vids of this step sorry!

|
Here's a close up of the of the completed part. |
Another close up |
Making elevation slider was next.

|
Why such a big chunk of metal for such a small part? you ask. I though I might need more then one shot at this part. As it turned out one was all I needed. |
Millin her done to the correct thickness |
Next step is to cut a slot down the center to make room for the key seat cutter.
|
|
|
|
1/4" end mill down the center |
First pass almost done. |
Next step was to cut the slot for the slider to fit over the sight tang.
|
|
|
|
Using a 1/4 X .0625 Woodruff cuter |
The slots are .040" deep. I did .010" a pass. I always go slow and take light cuts. Makes the tools last!! |
Next step I cut the dish for the rear sight groove.
|
|
|
|
Getting ready to make the cut |
It's cool how the flash makes the chips look like frost. You can see the completed cut in the background |
|
Sorry no video of this step |
Next I cut the slider off on the band saw and trued the edge
|
|
|
|
Getting ready to make the cut |
All done |
Next step was to drill and tap the 0-80 hole for the bolt that keeps the slider from falling off
|
|
|
|
Center drilled and ready to drill |
Hole drilled nad ready to tap |
