Didn't mean that at all Beth. I just meant to say that steel castings aren't usually as poor as aluminum castings. Both will benefit from lapping.

Lapping tool.

Watch the video. It'll give you the idea of the process. I don't go just forward and back, but left to right also. Kinda like a figure 8. On the 1st pass, just be sure to not tighten the rings so much that tool won't move. But it does need enough contact to make it work. Lightly snug? Once the tool moves freely in the rings, take the top rings off and wipe everything clean. You'll see just how outta square the castings are. Apply new paste and repeat. Do this until yer happy with the contact area. Keep an eye on the screws. You don't want to lap the rings to the point that they don't hold the scope tightly.

If ya don't want to buy the kit, PM me yer addy and I'll let ya borrow mine.
