I picked up a '46 truck banjo got the driver side drum off using my puller from vintage precision then went to the pass side.It got tight to turn the nut,so I took it off and got about 5-6 threads kinda stripped....Can the end be safely welded when/if I get it off.I'v only got a map bottle torch and wax-penetrating oil right now.Can the stripped threads be re-threaded after welding?

Some will tell you to find another axle.
When mine stripped I first took the axle out and had a smaller thread cut. I am sure it would have been fine but then I found a another axle and used that instead.
Install drum retainers after you fix it.

Post a pic of the damage. I have fixed a lot of perch bolts with the same thread.

As Andy says, it depends on the damage, but some have had luck with the split thread dies. You place the die ahead of the damage and back it off to repair the threads. The nearer the damage is to the end of the threads the better.

Texas Web If you have another rear end with a bad right axle you could use the good left axle and have a pair. they are interchangeable L&R.

I know people who have re-threaded axle shafts to a smaller size such as making a 9/16"- 12 SAE threaded shaft out of a 5/8"-11 SAE threaded shaft but when you do, a serious drop in the maximum torque value occurs with the smaller diameter. So much so, that the recommended axle torque of 200+ ft-pounds cannot be safely achieved. Again, some have done it without a problem but why roll the dice?
