It's really a pretty simple and straight forward process. I made this one using nothing more than a drill press, a hack saw, a file, and some wet/dry sandpaper.The most difficult part was soldering the nut to the sight base. Had a hard time getting the solder to stick to the base portion. Ended up putting a very thin layer of solder on the nut portion, then C-clamping the two parts together with a coating of flux between them, thenhitting it with the torch (You need three hands and monkey fingers to do the C-clamp thing ).

If anyone wants to give it a try, shoot me an e-mail with a phone number and the best times to call, and I'll talk you through the process.
