G'day
I need to change the front sight cam in my 686. The front sites are secured by two different size pins. I would like to order the correct size cup head pin punches. Can anyone help with the diameter of the pins / punches.
Thanks in advance.
cheers

Someone here used a nail set.They are cupped and come in different sizes. Cheaper to.They said they worked well. Just my 2 cents.

Evening Patrick and thanks for your reply

Hopefully i'll be able to source the right tools for the job, as the punches are quoted as #1, #2 etc.

Brownell's sells the cupped pin punches.

I've found it fairly easy to make my own. Take a 1/16" pin punch, chuck it up in a drill press, and turn the last 1/2" down to the diameter you need with a file. Then use a Dremel with a round dental bit to put a concave surface on the end. It takes about 5 minutes, and it costs a lot less than buying the cupped punches from Brownell's.

Evening fellas
Still not sure exactly what size punches are required. I managed to source the standard sizes of punches that are available. Please see below for future reference.

Sizes of punches:
#1 is .057", 1.4mm, long length
#2 is .066", 1.7mm, long length
#3 is .072", 1.8mm, long length
#4 is .040", 1.0mm, short length

#6 is .050", 1.3mm, long length

Try telephoning Brownells - they have people that are knowledgeable about stuff like this.
