Liner Removal

Step one of getting the 1972 CB 500 back on the road was removal of the failed Caldwell tank liner installed by the previous owner. I started by rinsing it out with dawn dish detergent, then moved to Simple Green HD Pro. A lot of really large flakes came out but I could see that I needed something a little more powerful. I filled the tank with acetone then added some bolts and a 3 foot length of chain as an agitator. Every couple of hours I would shake the tank then shift its position so that the acetone soaked the entire tank. After 18 hours I rinsed the tank with the hose and huge chunks of liner came floating out. I then finished the clean out by modifying my shop vac with a smaller hose. I do not have an inspection camera but wanted to make sure all the liner was out before I started with Step 2 rust removal. I called Atlanta Motorcycle Works in Woodstock and they were kind enough to put the tank on a bench and scope it for me. Good to go. Next step is soaking in Evaporust.

Filter

Jen and I recently went to 967 Coffee, a fantastic Yemeni coffee house on Highway 9 near Alpharetta. Jen had a Yemeni lemonade, which after some googling we learned was actually limeade, and made by blending entire limes– peel and all- with sugar and powdered milk. Sounds questionable, tastes like liquid magic. I had a coffee spiced with cinnamon and cardamon – which I recreated this morning in the pour-over cone. It made the entire house smell like fall. I drank it while reading about how Sufi mystics in the mountainous highlands of Yemen first roasted and brewed coffee beans in the 15th century to aid their concentration during long night prayers and whirling meditative dances

Overtravel Adjustment

As promised, below is the video explaining how to set the overtravel screw on a Sig P226.

Required Tools/Supplies: 2mm Allen Key, Purple Loctite, Headlamp (Optional)

Steps: (1) Clear and field strip the weapon; (2) Use 2mm Allen wrench to remove screw and apply purple Loctite. I used a headlamp to better see the screw and a Q-Tip to apply the Loctite. A toothpick would also work; (3) Use 2mm Allen wrench to reinsert the screw; (4) Tighten screw by turning it clockwise with the Allen wrench until the hammer will not drop; (5) With the trigger pressed, turn the screw the other way (counterclockwise) until the trigger drops. (6) Then turn the screw one additional quarter turn counterclockwise; and (7) Reassemble weapon.

Notes: I was required to figure this out because my set screw came loose and lodged between the trigger and the pistol frame while dry firing. If you carry the weapon for duty I would recommend calendaring a date annually to check the screw (maybe the same date you change the batteries on all of your red dots).

Ignition

Looks like I am going to be able to avoid installing a new ignition on the 72 CB 500. Luke, the guy who sold me the bike found the key while he was moving and sent it to me (thanks Luke!). I have just the key chain to go with it. Resurrection of Brother Moto – at least in spirit.
