You could countersink the inner side of the crankarm so the pedal thread comes through and use a lockring.

It'd be even more fun to machine the pedal shaft and the crankarm so one could insert a circlip at the end.

Because...why not?

That seems like a sorta crazy way to do it. I've made a few right-hand threaded cranks into left-hand, and vice-versa. The classic way is to use threaded cylinders, threaded inside and out, kinda reminiscent of HeliCoils except they aren't coils. (A lot of people talk about helicoiling a crank, but that's technically incorrect because but HeliCoil is a brand name, and they don't make them in pedal thread sizes). The ones I use are Eldi brand. They come in a kit with the RH & LH threaded inserts, and the oversized taps. Best done on a milling machine for precise alignment, possible on a drillpress if you're careful. Don't try it free-hand unless you don't care which way your pedal axles point.

My late-'80s tandem has Campy Record cranks that I made into a crossover drive by reverse-threading 3 of the 4 cranks. Has worked flawlessly for over 30 years including racing, long miles of "spirited riding", and loaded touring, under a heavy team. Well, Laurie is petite but I am a clydesdale+. I think cranks rethreaded this way are pretty much as good as "factory" pedal threads, if done precisely.

Oh and did you know this can be done with two different ratios? (Apologies if this has been mentioned already.) Jocelyn Lovell for example used it for the '82 World Championships kilometer time trial, which is done on a track bike from a standing start, so having a lower gear to start is an advantage.

There are a couple ways of doing it but Lovell's '82 Worlds bike used a single-speed freewheel on the right side, and the higher gear (smaller rear sprocket) on the left side. The smaller left one was a regular track cog, but with the lockring not threaded on all the way. That gave him an 87" gear to start, and a 95" gear that kicked in once the left-side cog unthreaded far enough to hit the lockring. After that point, about 70m into the 1000m total of the race, the lower gear on the right simply freewheeled.

Whether the extra weight of the second chain, chainring and freewheel was worth it for the lower "hole shot" gear is debatable. He didn't win; 4 seconds off the winning ride was only good enough for 7th place. The commisaires might have had something to say about it if he'd won. UCI commisaires have been known to disallow bike innovations after the fact, if the rider wins. Some say it's politics, business considerations or just good old fashioned bribes that determine whether a particular idea is allowed.

If you are ever in Gainesville Fl, late July-September, SwampHead puts out an IPA called Daytripping. Now I am a stout/amber ale person, but this stuff is awesome. They use 4 different kinds of hops. Still an IPA, but just somehow is actually good.

"In the real world", this would be known as ex post facto.

Personally I prefer to be even handed in all things, not to get two cranked up as it were.

I also have perfected the brutus force method of changing threading patterns but I found myself getting cross over it.

[For the record..... Kahunas is an Hawaiian word for a person with deep spiritual wisdom or a shaman. It is not referencing someones part in the procreative process.]

Spelling an old saying differently doesn't change the way people actually hear it. "You don't have the cojones" means what it means.

Usually the word Kahunna is preceded by big as in 'Big Kahunna' which refers to the more/most powerful priest. It was a popular saying back in the surfing days in Hawaii. I'm 67 so I remember that.

I honestly wasn't thinking about cohones as in Canada we don't learn Spanish, we learn French as a second language.

One can never post enough Python clips, thanks Al

I remember in high school Spanish learning that cajones meant drawers (like in a dresser) and thinking that somehow drawers was some sort of weird slang for balls. I couldn't figure out what the connection was.

Hey it's Mercury retrograde from June 17 to July 11. Miscommunication is rampant then, but the bottom line is that it always works out. Just don't get caught up in it thinking it's serious.
