Help, I'm in the middle of working on my 1949 sc but I can't unscrew the carrier screw. It is in there so tight. The screw is already buggered so that's not helping. I have a good lyman screwdriver but that's no help either. It soaked in breakfree and tri-flow for 24 hours and it won't budge.

What do I do?

I need to get it out, the carrier is filthy.

Jeff,
Try putting a screwdriver in the screw slot and tapping on the end of the screwdriver. give it a few good raps, bear down hard and try to loosen the screw. If that fails maybe a little heat from a propane torch will loosen it.
I also believe in Kroil oil it will work when others fail.

I would try Kroil oil for 24 hours b4 flaming it.

 

[ChefJeff1]

I don't know about blow torching it, it is the receiver and I don't want to ruin the whole gun. I read to put an extra bit in the screw and heat the bit. I need to get the kroil. I already ordered an almost cokplest screw set for this gun as a restoration so I don't care if it gets messed up more, I just want it outta there.

Apply some penetrating oil to the head of the screw and put a hair dryer on it until it gets real warm then more oil and hot air and then tap a screw driver like described by Greg.

When all else fails, take it to a gunsmith. He can drill it out without ruining anything else.

Kroil first. If you have seen the model 72 I took a part over in the rimfire section, it works real good on rusted screws and pins that had been left out in the weather for many years.

You can also go to Harbor Freight and buy a tool called an impact driver.
You will need to find a flat head bit that fits you screw and the driver.
One or two whacks, and it will come loose.

Soldering pencil on the screw on the opposite side may take a while but sometimes it does the trick.

Try prick punching the screw then drill a hole in it with a small drill then apply the heat.

I'm waiting for the auto parts store to get kroil in a few days. I"ll try that and heating before i have to take serious action. In the meantime, 1 coat a day of tung oil on the wood. I also ordered a bunch of new screws from numrich. It'll be like new when I'm done.
This sight has been an absoulote inspiration for me and a great place to hang out. thanks, Jeff

You know were going to need to see some pictures, preferably before and after. ;D ;D ;D

Well, I took my barrel and action to my LGS. He tried to unstick the screw and made it a bit worse. He recommended Brockmans Custom. I gave them a call and stopped by. They fixed it in about 5 minutes and set me up with a new factory sight for cheap. Great bunch of guys. I'm sure happy to get this project going again.

 

[swany]

Glad your making progress, good luck and don't forget the finished pictures.

 

[ChefJeff1]

I"ll take some pics for sure, ijust got my first non-phone digital camera.

The wood looks great, the screw is out, now I'm de-coppering the barrel and giving all the little parts a final cleaning.

FYI, the gunsmith gave the screw the "heat a bit with a torch" treatment and a few hard raps and it came out.

Don't know if I still have the link but the best penetrating oil for removing stuck screws found by a test done in the aviation industry is automatic transmission fluid thinned with acetone. Outperformed all commercial products.
