The cross feed screw on my HP 14" M-5 slab saw has some munched threads, causing sloppy cuts closest to the vise, so I need to remove & replace it. In this post I mention crossfeed screw & feed screw. They are 2 different things. The crossfeed screw moves the vise side-to-side. The feed screw moves the vise front-to-back. The crossfeed screw is too long to slide out without hitting the sides of the box. I was hoping I could get it out without removing the entire rail assembly. Notice the 3 bolts circled. I hoped that I could remove the 3 bolts and pivot the assembly so the crossfeed screw can be slid out. The trouble is that the feed screw is attached through the rail mount & won't let me pivot the assembly. So, can I remove the feed screw without removing the entire feed assembly? I removed the set screw holding the collar on the feed screw, hoping that the collar would slide toward the rear & allow the screw to slide out the front. The collar wouldn't move. I'm reluctant to put any force into it before knowing if it is supposed to slide back. Is anyone familiar enough with this design to tell me how to get the feed screw out? Or am I stuck with removing the entire carriage assembly? TIA Lynn

With a small allen wrench you can remove the set screw on the collar on the feed screw that is on the inside opposite of the gear. Once it is loose it will allow you to pull the feed screw out the front of the saw.

Did you turn it to make sure it only has one set screw? If so try heat to get it to free up. Probably should drain the oil first though. Whatever you do be gentle with the gear.

Thank You, Thank You, Thank You! Rockoonz - You are a genius. Yes, there were 2 set screws. I removed the second one, slid the collar towards the rear of the saw & pulled the feed screw out through the front. Then I rotated the carriage assembly counter clockwise and slid the crossfeed screw out the right side. Drain the oil? Clean the saw? Yeah, I guess I should be nice to my saw. It's been a long time since it got a good cleaning. There's a place where the plexiglas top is separating, so I'll get it all cleaned of oil & re-glue it. I hope this thread helps anyone else who needs to disassemble their Highland Park slab saw. Thanks again for a second set of eyes & another brain. Lynn
