I have a supermax ycm1 1/2 va and somehow the feed needs (2 nut design) came out of the bracket so I removed the table and lead screw to feed the assembly back into it but noticed there were no adjustment screws at all not even a tapped hole for an adjustment screw to go into. The bracket does however have a boss where it looks like the screw would normally go. Is there some other mean of adjusting the backlash on these machines?
