2 quick, cheap, and easy to use lead testers.
the first one i built i ground the point of a princess auto
spring center punch untill i had 1/8 in flat . i then ground
2 flat sides like a screwdriver blade ,1/16 thick blade on the end. this will go in soft lead .036 thou, .025 thou in
ww lead, .007 in quenched ww lead, and .005 thou in a 20
brinell hard lead bullet this is measured with dig vernier
calipers. this would be useful for a visual quick test without the calpers.
OBTW i bought 4 of theses spring center punches at
pricces auto yesterday, $8 bucks each.
the other tester i just built is more accurate .
i ground the point into a flat scewdriver blade, .030 thou
thick x .200 thou wide. then i ground the blade v shaped.
see pic. this tester will give a .212 wide slot in soft lead,
.184 in ww lead, .133 in quenched ww lead, and .108
in a 20 brinell hard bullet. u measure the slot width with
dig verniers of course. it don't come much easier and easier than this
