Friction jeweling tools


Friction jeweling tools
This tool is used to ream, press in and make adjustments to friction jewels. If the jewel to be replaced is a friction jewel, you need only press out the cracked or otherwise damaged jewel, determine the size of the hole (if the hole is not damaged), press in a friction jewel of the proper diameter and pivot hole size and adjust for proper end-shake. If the hole has been damaged, you should ream it with the next size reamer and then press in the proper size jewel.
In replacing other types of jewels with friction jewels, a more thorough knowledge of jewels and jewel settings is needed.
