Making a good pair from two bad ones?

[mdstuart]

I was wondering if you could buy one of those not good zoom 100mm bins and then replace the eyepieces from another pair of bins and make a decent 100mm pair of bins..

Is that possible....as a fun project?

It would be a possible project, but whether it would be fun is doubtful. Ripping zoom EPs out of binoculars is an act of mercy, to help the bins out of peoples' misery . Adding ordinary EPs could perhaps be done, but I doubt it would be easy to get collimation right.

Probably possible as the objectives are usually the best bit of those bins but in general the build quality is a bit plasticy on and so the end result may very well be just a pile of junk with some superglue mess all over. Could experience some difficuly in get decnt focusing as the Zoom arrangement will have to go and will mess with the focal length. (ie. put the eyepiece in the wrong place)

but if the bits were cheap enough be worth a go.

You could always build a couple of MASSIVE finders out of them
