37:00 Kyle says he uses solder to tin his tip and says he doesn’t like using sponges to clean his tip.

38:35 Kyle desolders wire from switch and explains what the vinyl tubing on wires is for.

39:20 Imoto asks why we flipped the coil and Kyle tells us about vibration from coil stop and diode failure.

39:56 Kyle reminds us not to touch the iron to anything other than what we’re trying to heat up, watch out for wires.

40:20 Kyle solders the wire to the new switch

41:30 Kyle reminds us that dripping solder can cause problems

41:45 Kyle uses needle nose pliers to hold wire while soldering

42:30 Kyle slides vinyl tubing over the connection and suggests that it should be replaced if not present.

43:00 next wire removed and tells us about oxidized wires and ways to fix them.

45:55 Kyle shows that the EOS switch is now hooked and demonstrates its use

46:30 Kyle explains the use of the other side of the switch stack

46:56 Kyle desolders the last wire from the old switch

47:19 Kyle solders the coil wire using needle nose pliers to hold the wire 48:19 magic_ditto asks why Kyle has the playfield all the way up and not in the service position

49:30 Imoto asks what to do if you don’t have enough wire length, Kyle says you can extend the harness or don’t flip the coil around.

50:00 Use heat-shrink to extend short wires.

51:00 Kyle solders ground to switch then checks his adjustment

51:40 Kyle reminds us that he’s going to use heat shrink on the EOS actuator and why that’s important. (Pintip)

54:20 NetReamer’s tip about holding wire in place while solder is cooling. 54:50 Kyle examines switch adjustment

55:30 Kyle explains switch swipe and why it’s good (switch self-cleaning). 56:20 Kyle shows us the upper flipper and gets his tools.

57:00 Kyle begins upper flipper removal. (speed-run rebuild :))

58:50 Kyle removes crank and begins removing coil stop

1:00:00 Kyle removes the shaft and cleans dust from the flipper assembly.

1:00:20 Kyle removes Nyliner from the shaft and shows us the common wear on linear flipper cranks.

1:02:26 Kyle removes coil sleeve

1:02:50 Kyle replaces Nyliner

1:04:20 Kyle removes and replaces flipper bushing

1:05:18 Kyle explains that the flipper bushing screws are temperamental and shows us the correct way to align the threads (pintip)
