lapping project Profiling edge

175: Lapping machine project - motor mount plate, and skid plate.
174: Chinese ER collets - not EDM - full of burs - needs hand finishing work. I found a old rusty feeler gage blade - roughened up the edge on the grinder - worked pretty well to file out some burs.
173: Surface roughness tester Surftest 211 Disassembled Not the greatest design for the time - 4PCBs too many connectors. No need for two uP. All it needs to do is preamp, motor voltage, A/D UI. Don't recommend Mitutoyo - they go after people sharing manuals, no parts support on older units.
172: Surface roughness tester Surftest 211 Disassembled Batteries are toast Machining Schmoo got inside. Don't recommend Mitutoyo - they go after people sharing manuals, no parts support. There are better people to work with.
171: Welded a bit on so if lifting from below it will push out to clear the end.
170: Cut the bottom edge off.
169: This peg holds the weight bar for doing squats - it can get tangled up on the bottom side if you are not careful - leading to bad things happening.
168: Dome spring was stuck in the in position - a bit of bending fixed it up.
167: Plenty of Lathe cutters - for a guy still without a lathe.. Some gifted from art.
166: Boring bars gifted from Art - cleaned and oiled.
