choosing the right anvil

Thanks for your input. What specific problems occur with use of a surface that is too high? Within the last few days I was given opportunity to use a small (55Lb) blacksmith anvil.  It seems to work well for a few familiar tasks However, I'm currently teaching myself use of the copper rivet and burr type rivets for the first time. As I practice on top of the anvil with scrap bundles  my skill’s are progressing, but the burrs slant off  level far too often for me to attempt  installing on a nearly completed bag.  Of course with this type of rivet I am working on the exterior of the bag. Would being on a lower surface help with the problem I describe?

Oh ok, you literally mean like a Wile E Coyote type of anvil. I was thinking you wanted something small to fit inside tight spots and pockets etc.

As far as bending off-centre instead of compressing, you may want to hit more delicately, or use a lighter hammer. It comes down to feel and experience really, but too much weight or heavy hits often result in wondering shafts.

Thank you Tarik for your response, im not fully picturing this and how it functions. Would you post a photograph. Thanks Janet
