New sight soldering jig

[Jonnyofalltrades]

For years I have thought about buying a sight soldering clamp like Brownell's sells. Not really that pricey, at $90USD, but from past experience I know it would cost around $200CAD by the time I got it to my place. Also, I don't like the idea of having a large block of aluminum mounted on the bottom of the barrel right where I'm trying to evenly apply heat.
I was running a few ideas around in my head, and came up with something that works ok so far, and I was able to fab from scrap on hand.

Sorry about the milling machine in the background that makes photo #1 confusing!

The rear part that clamps to the barrel is made from aluminum pipe. The thumbscrew has a blob of solder on the tip so that it won't mar.
The front part is steel, and the slim front extension of the aluminum acts as the spring to provide downforce as the front screw is tightened.
Worked excellent the first go-round, with one problem. It obstructs your line of sight between the rear sight and front sight, so you can't verify alignment very easily.

Excellent idea. Looks like a smart solution.

Better than the spring clamp and mechanic’s wire I used last time.

That's been my usual solution for way too long.

It works but your jig would work better.

I made a clamp from two pieces 1/2 inch square steel, each about 3 inches long. Close to each end - drilled and tapped one piece, the other with holes for the long screws joining this 'clamp'. I cut a section narrow enough in the middle of one piece so it would drop freely into the dovetail section of a front sight ramp.
Tightening the screws up and using a level you can get the ramp exactly where you want it. I would post a picture of it but it went with my tools.

I use my Forster scope mounting jig. I level the barreled action up, then line the guide up over the sight ramp. I made a weight which fits through the hole in the guide. Weighs about a pound. The pointed end locates the ramp or base and maintains pressure.

Mine is really high tech - a scrap piece of flat spring bent to fit and fastened to the barrel with a spring clamp. Fast, cheap and effective.

I think I get the idea.
I need to incorporate some sort of rotational adjustment like that into mine .
Otherwise I'm repeatedly clamping and unclamping in hopes that "one of these times it HAS to be straight!".
