Unior Pedal Tap and Thread Insert Set 9/16" Review
I wanted some 180 mm for the captain on the tandem and 165 for the stoker (my spin rate is much higher than the stokers). Good luck finding these size cranks inexpensively! By purchasing inexpensive standard cranks and using this Kit, I was able to put correct left hand thread on the left side cranks (yes in meantime I did have to use some right hand pedals from road bike, and yes the Wright Brothers were correct, the pedals do unwind and work their way out !) . I could have thread-locked right hand pedals into the cranks, but what if it still works loose or if I use the super strong threadlock then it might need heat when ever need to remove? So yes I decided it would be much better just to do right, and also I figure it never hurts to invest in tools.So far I have converted 3 or 4 cranks. I was little concerned about get the new thread insert in perfectly perpendicular, but this tool is designed with good lead in taper to make this fairly fool proof. I had no issues. Typically I don't go all the way through with the tap but leave a thread or two so that the insert will jam onto. I also use the loctite cylindrical retaining compound. After it cures, with 45 deg chamfer tool, I remove what ever insert that is not in the crank.
I find the taps to be high quality and the left tap still looks like new after 4 or 5 uses. (be liberal with cutting oil !). I think I did use the right tap as well to convert some 170 or 175 left tandem cranks into normal cranks.
