Today seems to be the day for fiddly jobs. I got all inspired to make up the new front sights for the .44 and .36.

The brass rod is 3/16 round that I've had for ages. But I've seen such rod at Home Depot as well.

I still don't have my lathe set up so the 1/8 size stubs were turned down in my hand drill using a small flat file with a safe edge. It's easier than it sounds.

The holes in the barrels were drilled out from the slightly smaller metric size to 1/8 to the original depth. I then squared up the bottom with a flat ended drill bit that was custom sharpened by eyeball. It's easier than it sounds as long as you have a keen eye or powerful reading glasses... :D

The first picture shows all the bits for the .36 laying ready for soldering. The .44 stub is already soldered in place. The second picture shows the hi tech soldering jig that I spent many hours milling from billet.... :D

Sharp eyes may note the silvery ring around the hole in the .36 barrel. I actually used one stub as a lapping form with some fine compound to lap the blueing away. Turns out I didn't need to bother. The flux I'm using seems to do a fine job of removing the blueing or the solder is quite happy to stick to it just fine. I ended up with a slight fillet on the low side of the soldering job. So now I've got a little cleanup and some blue touching to do.

I'll post up another picture of the finished blades once they are done.

The idea of using the larger size rod is to

I know what you mean BC, the 51' Colt is the standard, sleek lines and perfect balance, but I just can't see that small bead front sight and it does need a bigger front sight. I like what you're doing there. :)

Crawdad, if you're blessed with "old guy eyes" like many of us it may not be the size of the front post. Instead it might be the ridiculously small "v" on the hammer. Wait until I post pictures of how I open out the rear notch. It really makes the gun far more "old guy eyes" friendly.
 
I opened up the rear sight on a mill, and dovetailed a new sight in an 1851.

I can't find the photo, but the dovetail got cut and polished with the side flats after centering the blade. And of course, reblued.

Rc' I like your style!

On my .36 barrel this would be a very good way to go. On the .44 the wall is only around .090" thick. I'd have to limit the dovetail to around .040 or so to ensure I didn't begin to risk the metal bulging out. So for now the soldered in post is OK.

Here's the finished shots of the new sight and the rear sight notch mod. Note that I chose to bevel off the nose of the hammer to get a head start on lowering the sight line so I end up with the minimum of front blade and a minimum possible fragility issues.

Although the soft soldering did hold up just fine to milling off the sides of the post with a 1/4 ball nose four flute mill. This one is a little more messy. After the front post sight is tuned for aim I'll likely clean up around the base to remove the solder and then polish it and touch up any damage to the bluing.

Pictures! Note that the notch looks really big only because the camera is between my face and the gun. The actual view from my face's vantage is that the post fills the notch from side to side at the moment. I'll leave it like for now until test shooting so I've got some fudge room for windage adjustments.

BC, I 'V' notch my rear hammer sight using a small triangular file. I cut it deeper to take up elevation and move it to either the left or right to adjust for windage.

I like what you're doing there and showing how the Colt's sights even though primitive can be adjusted. Just one more reason to love the Colts!!! :)

Here's my post here showing how NOT to adjust the Colt's sights. I jumped the gun a little but I think I now have it corrected. I should have included a pic of my 'V' notched hammer sight however.

I've used a #4X3/4 brass phillips head screw reshaped and epoxied where the front sight used to be.

I have a small hobby mill and cut a dovetail in the barrel. Used a spare barrel to cut and sand down the edges smooth. I have since flattened the top of the brass sight by a small amount and the Colt hits point of aim at 7 to 10 yards.

Installing a proper front sight makes them a pleasure to shoot. I hate guessing point of impact.
