This unit is out of storage now and should be taken apart and serviced. You will need to fit it to your lathe by choosing or making a T-Slot nut and setting the elevation as you need.
Many online vendors sell T slots so just do your homework. This was used on a 16 Monarch and performed admirably. We removed & set aside an Aloris IV set up because it was a paint to use.To make a quick T slot, cut a 4 inch long x (thickness of choice) piece of flat iron & then drill & tap into its center a 3/4 x 16 TPI (UNF). Fashion a correct height piece of 3/4 x 16 threaded stock. Attach the threaded stock & weld it in place. Slide it into your compound's slot, set the turret holder in place, add a washer & nut & snug. The turret then rotates by opening the operator handle, position as needed & then close the handle.
With some practice you can rotate in or out a half dozen tools. Value: We bought this new, used it for years and it has performed flawlessly. Condition : As stated: used, very good to excellent. Needs servicing as it has been in storage.
It also needs a T-Slot and proper fitting to your lathe. The unit should be disassembled and the bearings cleaned, repacked with light grease and then put back together.
As I recall the bearings are a set of balls and I think they were on the order of 3/8 in diameter. When you release the operator handle, an internal spring pushes up allowing the turret to index left or right without the T-Slot post being touched. That's how the magic of accurate indexing works. Once you use one of these, you'll never do without it. The item "One ENCO Universal 4 Turret Tool Post Holder for medium to large lathe's" is in sale since Friday, March 29, 2019.
