Here’s an interesting snag I’ve never run into before. .
"The pedal threads of the crank were so corroded that I couldn’t install the new pedals. The old POS pedals came off ok. But the new left one fought me all the way on, and I couldn’t get the right one started at all. So I took the bike to my LBS to have them tapped. The left side cleaned up fine and the pedal went on smooth. But he couldn’t even start the right one. So I attacked it from the inside. He got 3/4 of the way through and it felt like he hit a wall. You can see where the clean threads end at the corroded threads"

"So I came up with the idea of giving it an evaporust soak. So I brought it home to soak it"

I keep two sets of old spindles from discarded pedals to use as thread chasers.
"When pedals don't fit the 'right' way, nail them from the opposite direction. Have not ruined the tools or the crank arms yet."

Great work, guys.

It would be nice to have a left-hand tap for that. I’ll bet they are widely available. I have lots of taps and dies, but I don’t have a single left hand tap or left hand drill bit.

Whipped up this handy little gadget because I don't like workbench clean-up. Nothing more than a yogurt container, broken spoke, a strong magnet from a dead hard drive, and a dab of JB Weld.

I have a Park Tools set from the 80s when I modded a set of Ofmega cranks from 172.5 to 145mm length for roller racing.

A Wald 13/16 inch replacement 15 1/2 inch long seat post. These suckers are light and bend. I believe it’s 3/8 inch galvanized plumbing pipe I use to reinforce it. Cut off threads on one end, remove burs, slather the galvanized pipe with JB Weld to act as a lubricant, place the seat post on a wood block and spend about 10 minutes hammering the galvanized pipe into the seat post. Cut off what you can’t hammer in. I got about 12 inches in. Alternately you can bench grind a little off the plumbing pipe.
