Any interest in "big eyes" plates?

[snopro176]

I made a simple plate for my Kowa 664 30x spotters that works pretty well. Isn't nearly as elaborate as the adams adapters plate but its functional. I'm taking mine to a cnc shop this week to have it modeled and a precision one cut(i did mine on a manual milling machine) and I was wondering if there's a need to make more. Seems to me the adams adapters for the kowa 664's is discontinued. This should also be adjusted for a different size "foot" or base for a wide range of spotters like the compact vortex and who knows what else.

How do you accomplish collimation and retain the adjustments?

That looks like it’d get knocked out of collimation way too easy without some sort of objective support and how do you collimate effectively without it?

Ill have to take better pictures once its finalized. Theres 2) 1/4-20 set screws, one at the front of the mounting bolt and one at the back. That allows you to adjust the vertical pitch. The slot they sit in is a few thousandths over the size of the foot so you can angle them in and out until your picture is aligned, then you snug the 6-32 set screws on front and back to keep the foot in position. I understand the adams adapter is practically a vice for them but this design works and is much easier to make, which will make it much cheaper. No you won't be able to drop them on the ground and retain collimation(at least i doubt it) but if you take care of them like you would any other piece of glass, it'll be sufficient. I realize this isn't as solid as it could be, but it is simple, lighter and cheap enough for me to dabble in the big eyes world, and that's all I was after.

Interested in the pictures. I have thought the Adams was over engineered, which is what most people want.

Sounds like it suits your goals. Probably fine for a truck type glass. I'd lean towards the Adams or Wells for day in day out for in the pack, in the field use though. The Wells is pretty lean and simple.
