New Anchors How To Remove The Old

New anchors on QuickDraw McGraw at the Central Scrutinizer Wall Potrero Chico.

The old ones are cold shuts and very worn. I have some photos at the link.

Any suggestions on how to remove the old anchors? Sawzall maybe?

The new anchors are 1/2 inch stainless 5 piece bolts from ASCA and Mark Grundon. The chain is galvanized but it has a stainless screwlink between it and the hangar.

Oh yeah.... I was thinking about going back up with something longer like a "cheater bar" for more leverage.

CORDLESS GRINDER!
