Removing safety detent ball

Post by MBiz » Tue Oct 20, 2015 5:36 pm

Hello everyone,
I am restoring a 1917 M8, S.N. 39291 and I have encountered a challenge. That is how to dismantle the safety detent ball and the front sight ramp on the barrel jacket. Does any one have experience with either of these parts. Thank you for your help

Great questions. I've had success removing the detent ball by the pictures below. I basically took a needle w/ a plastic head, broke the needle in half so it's shorter. Then grabbed it with a pair of pliers. I then inserted the needle into the receiver and down into the hole of the detent ball. Next take a hammer and begin tapping the pliers. You'll definitely want to put something under the detent to catch it when it comes out, otherwise you'll never find it!

As for the front sight, you'd need a front sight pusher to do it proper-like. The company Williams makes a nice one which prevents any damage to the sight base. Hope that helps.

If you are talking about the front sight ramp base It's brazed :shock: in place. The heat to remove can ruin a blue finish, and sometimes raise scale :oops: :cry: on the barrel sleeve and base. Remove at your peril..... :oops:

Thank you for your help. How about ''grinding'' the edge of the ramp or touching it with the zip cut.

If you will look inside the end of the barrel jacket, you should see the head of the rivet which attaches the front sight ramp. It is about at the end of the threads. That should line up with the center of the dovetail, and it can be easily drilled out.
The fore end lug is attached in the same manner, except it uses two rivets.
