This video details the process of fixing a slow-timed Smith & Wesson revolver by replacing the factory hand with an oversized one. It covers diagnosing the issue, identifying the worn hand as the cause, fitting the new part, and refining its action with a bevel to ensure smooth lockup on every chamber. The repair results in perfect timing and a ready-to-use firearm.

Quick Summary

A slow-timed Smith & Wesson revolver often results from a worn 'hand' failing to rotate the cylinder sufficiently for lockup. The fix involves fitting an oversized hand, which is slightly wider, to ensure full rotation. Refining the hand's leading edge with a bevel can smooth the action.

Frequently Asked Questions

What causes a Smith & Wesson revolver to be slow-timed?

Slow timing in a Smith & Wesson revolver typically occurs due to wear on the 'hand' or its slot. This wear prevents the hand from rotating the cylinder far enough for the cylinder stop to engage the locking notch properly when the hammer is cocked.

How can I test if my revolver is out of time?

To test for slow timing, load snap caps into the cylinder. While cocking the hammer, apply light finger pressure to the cylinder. Observe if the cylinder stop moves into the locking notch just as the hammer reaches full cock.

What is the standard fix for a slow-timed revolver?

The most common solution for a slow-timed revolver is to fit an oversized hand. This replacement part is slightly wider than the original, ensuring it forces the cylinder to rotate further, thus achieving proper lockup on every chamber.

How do you smooth out the action after installing an oversized hand?

After fitting an oversized hand, the action might feel rough. You can smooth it by carefully beveling the leading edge of the hand using a fine India stone. This modification helps the hand glide over the cylinder ratchet more easily.
