LiFePO4 conversion. Made brass strips to clamp the terminals. Messy wiring.
162: LiFePO4 conversion - lots of room left in battery cabinet.
161: This was $40 + $15 on ebay. Turns out is is some kind of reference - calibration sticker on the inside. Taft-Peirce MFG Co. - Company disloved in 1995 - some products moved to Suburban tool. Supposed to be precision. Rust damage..
160: Drilling rubber corks with brass tube. Makes pouring cream in my coffee Much more controlable.

165: Micrometer head from the 80s - hand laid out traces - looks like this board often shorted on the metal - needed thicker stand-offs. Early optical encoder - not repairable without spending a days redesigning.
166: Boring bars gifted from Art - cleaned and oiled.
167: Plenty of Lathe cutters - for a guy still without a lathe.. Some gifted from art.
168: Dome spring was stuck in the in position - a bit of bending fixed it up.
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.
170: Cut the bottom edge off.
171: Welded a bit on so if lifting from below it will push out to clear the end.
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.
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.
