How did I ever live without this? In my little world, I have had
to mark and drill holes for bolts, threads and pins and have gotten
lucky and not so lucky. The mark of a good machinist is how well
he RECOVERS from little inaccuracies. My designs have always
included fudge-factors for eyeballed holes, as setting-up
edgefinders and using the BP for drilling every hole is just too
time consuming and relies on accurate edges, good math and
back-lash problems. My thanks to the person that came up with the
optical center punch, it sure fills a spectrum of jobs. I think
this should be one of the first tools in a machinist's box!

How 'bout a link, Tom?


I googled it and found a bunch. I bought one from one of my
customers, "Production Tool Supply" but, I would recommend
Fowler...just because Fred is such a good guy...and it's $10 cheaper!


This is the one I use

Hey Ken,

$31.50 US on your webpage, $39.50 Cdn in the 2005/2006 Canadian
catalogue which arrived with the Bull O' the Woods books yesterday.
Some other neat stuff there too.

Brian.
