Tappet adjusters

[Allan WebsterParticipant @allanwebster78962]

In a recent thread Andrew Tinsley was enquiring as to how he might put a ball end on a screw. Can I respectfully suggest that he finds a ball bearing of the correct diameter and drills a hole in it. The end of the screw can be turned down to fit the drilled hole and retained with epoxy since the joint will be in compression. I have used this method often as it does save all of the time that would be expended in making a form tool, turning, polishing etc. etc.

Hello,

Thanks for the idea, The O/D of the thread is 1/4" UNF, The hemisphere on the tappet adjuster is actually the core diameter so a good bit smaller than !/4". By the time the thread has been turned off and a hole drilled in the ball bearing, you are talking of a very small spigot diameter. I am not sure I like the idea for such a small spigot I suppose JB weld may be OK as an adhesive, but the ends of tappet adjusters get a good hammering. I would be afraid that the small spigot would break and that could cause a fair bit of damage

Regards,

Andrew..
