When you bolt the motor on it will staighten up, the alum. beam is butt blued to the ply disc with epoxy and then bolted in place from the inside with a large round washer/spacer thing, looks kinda like a blind nut but not threaded and no spikes, it serves as a spacer to allow tightening of the screw without crushing the ply disc, some crushing does seem to happen and warps the ply a little causing the beem to lean, bolt it to the motor and let it sit a couple days to see if it hols its shape. Don't ask how I know what the inside of a hyde mnt. looks like.[&o] It may not hurt to give Meryle a call and ask what he thinks as the above is just my opinon.
