All, I'm having real trouble wall mounting my JM Labs SIBS. Basicall the (sparse) instructions say use a 6mm masonry drill bit and push the plugs into the hole. However, concrete lintels aside, the holes I DID manage to drill (in breeze block by the look of it seem simply too small for the plugs. I cant get them more than 1/2 an inch in before they wont budge any further. Anyone else tried wall mounting these with the supplied plugs? If not, nayone got any tips on what the fork I'm doing wrong? (I'm a complete DIY muppet by the way).
