clamps are great for gluing bevels. Ulmia also offers a finger clip, which is great for small jobs and doesn't require a spreader. To the reviewer who was so annoyed with the glasses. In the past, when I needed to clamp something that I didn't need holes in, I used sacrificial boards (door boards or MDF) on the clamping surface. I've been using them for years and couldn't imagine not having them.
