Being satisfied with what we already have is a magical golden key
to being alive in a full, unrestricted and inspired way " -- P.Chodrön
My small astronomy tools:
Classic refractors; visual observer, old school.

Quote:clamping it in a large vise
Quote: I've decided to go ahead with the vice as a first approach.Seems like the most gentle, incremental and yet controlled way of straightening out the bend.

Quote:Put it on an anvil and tap the bend with an engineer's hammer. As the bend straightens out, roll the shaft on the anvil, tapping the shaft to get the bend (presumably straight) you want. Don't use heat as it will melt the plastic handle.
What some may view as an argument I view as a different perspective.
Quote:vise vis-à-vis vice versa
Quote:The vice will allow you to slowly and evenly apply compressive stress to the metal without as much chance of metal fatigue. Repeated blows with a hammer will possibly cause fatigue, metal crystallization and fracturing.

Quote:Be very careful. You can see in the following photo, posted by one of our CN Classics members, the point of weakness where the threaded portion meets the unthreaded portion. You can see in the photo that the shaft was bent prior to fracture. Don't know if the fracture occurred at the time of bending or during an attempt to straighten it.
