Once installed with proper lash on the gears it works great. A few parts are junk but at this price you simply can't complain or really expect much more. Here are the issues I found when installing on my Bridgeport Series 1 2HP:
1. The gear comes pre-greased with some NASTY gooey stuff that you HAVE TO get off completely to properly set the lash... That's just dumb. They need to just put the goo in a little squeeze packet for the user to put on after setup or just skip it altogether and put a note for the user to be sure to grease the gear. How dumb is it to pre-install gelrease that you have to remove/waste?
2. The brass gear was 0.200" too tall for my machine so when I put the original handle back on there weren't enough threads for the nut.... Simple enough to machine it off and definitely better that it was too long than too short!
3. The limit stops are plastic and mine weren't molded "square" so the spring loaded stops were angled away from the table and barely made contact with the switch. Super easy part to make out of aluminum but something that simple should be correct out of the box.
4. No bolts are included to mount the limit switch to the machine.
5. The small bolt intended to attach the plastic cord holder clip under the table to route and secure the limit switch cord is the wrong size (too small diameter) and it already BARELY fits through the plastic clip. I had to get a new larger bolt and corresponding clip.
6. The bracket that mounts to the table has oval holes, presumably to make this more generic and fit more clones. The downside is that the socket head bolts don't have a full and solid seating surface and when tightening you can feel the aluminum giving way under the clamping force. The solution is to use a washer but off the shelf washers didn't fit into the recessed hole so I went to the specialty hardware store and grabbed 4 machine screw washers and they fit (barely). Sanding / turning down the perimeter of regular grade 8 washers would work too.
All in all, it is good for the price and the few inconveniences aren't what I would consider a deal breaker. The sad thing is that those inconveniences were 100% avoidable with perhaps a 5 to 10 cent cost increase to the manufacturer.... And if they DID implement those changes it would make this thing worth more simply for time and frustration saved! Heck, I probably wasted $5 worth of acetone and brake cleaner and added 30 minutes to the install getting all the Shmoo off the gearbjust so I could set the lash properly!
