Tool Centre Height

[John McNamaraParticipant @johnmcnamara74883]

Hi All

This simple centre height tool has served me well. Some will recognize the Red “Eclipse” button magnet at the base. An old fashioned Alnico magnet not strong compared to the new rare earth magnets but the right pull to hold the gauge upright and in place. If you use a rare earth magnet put it in a steel tube to reduce the pull, otherwise you will spend a lot of time trying to get the swarf off. A simple matter with the eclipse magnet

The eclipse magnet came screwed ¼ whitworth so it was an easy matter to thread a small piece of ¼ inch bar and make a small slider block from scrap.

I prefer to be able to see the alignment and found that I can feel any error with my finger; others may prefer to use the bottom surface of the gauge block.

Cheers
John
