Sight adjustment
The front sight on my new SGC definitely needs to be drifted. Don't have a brass punch, so tried with an oak dowel. Would not budge. Probably because of the light weight gun vise I have resulting in inadequate resistance when hitting the dowel. Started using a rawhide hammer just to be safe. No luck, then a regular hammer, again no luck. I'm sure all because of movement of the vise. Thought the dovetail would move more easily. Sure don't want to mar up a new rifle. How do you people secure yours safely enough to get that sight to drift? Don't want to have to go to the local gunsmith for what I think should be a simple task. Any advise would be greatly appreciated.

Re: Sight adjustment
Do get a brass punch. An oak dowel will absorb too much of the energy from your hammer. In a pinch, you can put a brass shell casing over a regular punch, but the brass punch is the way to go. Skinners will have one for you. While you're at it, getting a triangular file, too, for trimming dovetail sights when you change front or rear sights.

Re: Sight adjustment
You need a good bench block and a solid bench to rest the muzzle on while drifting the sight. If you don't have a good bench block you can use a roll of black electrician's tape on its side. NCG's suggestion of using a shell casing over a regular punch is good idea - I've used a spent 22 casing on a regular steel punch to drift sights before I got a good brass punch from Skinner. Sometimes you have to really hit it hard to get some first movement on those front sights, but eventually they move...

I'd have the rifle laying on it's side on top of a solid work bench with an appropriate thickness slab of wood to uniformly support the length of the barrel. Then punch as NCG shared.

Re: Sight adjustment
If a dovetail is particularly hard to drift, I've used a couple of drops of RemOil on it. Seems to help it move easier...

Re: Sight adjustment
Have been off line all day. Tab ran out of gas, had to fill-r-up. Thank you all so much for the very valuable advise. I'm going to apply methods learned here tomorrow. Just never " drifted " a sight before. Only mechanical, rear sights for windage and elevation. Even though I have shot off and on for over 50 years, I'm totally guilty of pretty much overlooking too many details. Great to have support. Big thanks to ALL!!

Re: Sight adjustment
Will do NCG, punch and file both. Is the angle of the dovetail and a standard triangular file the same? I think I have a small one out in the shop. Then all I need is the punch! Also, will lightly filing hurt anything? ( blueing, finish, promote rust etc.? )North Country Gal wrote:Do get a brass punch. An oak dowel will absorb too much of the energy from your hammer.

Will try the Rem Oil if needed. I'm gonna move that sucker one way or another.PT7 wrote:If a dovetail is particularly hard to drift, I've used a couple of drops of RemOil on it. Seems to help it move easier...

Re: Sight adjustment
Thank you Tractotad. A real good first tap/hit may just be the answer along with all other techniques offered so far.tractortad wrote:You need a good bench block and a solid bench to rest the muzzle on while drifting the sight.

Re: Sight adjustment
When drifting sights by pushing or tapping them, I place a piece or two of blue masking tape over the work I am going to contact with the sight tool or punch. As a matter of fact, I use blue masking tape to protect any finished metal work around the area where I am going to drive pins in our out.
