House and Car Key Chain

[Paul Jones]

This is a great gift for friends and family.

Along the lines of my previous postings for "kitchen utensils" with knurled stainless steel handles (see e.g., http://www.homemadetools.net/forum/k...323#post107011 ), I made key chains that are allow the house key and car key to be separated (great for valet parking).



The key chain can be separated into two individual parts by unscrewing a stainless steel 8-32 threaded part. The main body of the key chain is made from 0.375" diameter stainless steel 303 rod turned-down to 0.364" for a very clean 21 pitch knurl application. I used a 8-32 SS all-thread rod attached with Loctite 620 rather than single point threading or cutting with a 8-32 die. Every way would work very well but by taping a 8-32 thread and gluing in the 8-32 threaded rod was a much easier operation.



I bought the stainless steel rings at Amazon and the combined small and large pair allow a very flexible key chain for being in your pocket or purse.



Thank you for looking,
