Hello All,
I have had the Vevor x y table for a year or two. I got tired of running out of travel in the shorter direction. So I decided to modify the table. It turned out to be a fun project. Here are some pictures after I finished.
Basically I removed the short acme threaded screw and replaced it with a standard 5/8 inch threaded rod. Then moved the bearing mechanism outside the cast iron frame and cut the ends of the casting out to allow the threaded portion through for longer travel. It the pictures you will see the 3.5 inch round aluminum rods I added in the front and 2 inch ones in the back. They were to shift the bearings outside the casting. I now have 8.5 inches of travel in the "Y" direct and 13.5 inches in the "X" direction by doing the same mod on the longer axis. (2.5 inch rods added). A standard 5/8 x 11 right hand threaded rod about 18-20 inches was what I used and it is a whole lot cheaper than trying to find a special acme threaded rod. Of course the inside nut had to be changed for the 5/8 threads. It Ttkes more turns than the acme threaded rod but that is minor compared to the frustration of drilling several holes only by moving the part after being clamped down. The aluminum knobs were replacing the wing nuts. On the shorter axis I drilled 3 more holes in the casting to shift the gib set screws and added another knob. That allows two set screws on the gibs at all times even at full extension either way. The center picture show the screws holding the nut. I had to change them to a flat top hex screw to allow the other acme rod to clear them.
