Mophorn 5 Inch Dividing Head Set 3-Jaw Chuck BS-0 Precision Semi Universal Dividing Head Indexing Head with Tailstocks Dividing Head for Milling Machine Rotary Table Tailstock Milling Set

Very well built, smooth operation, fast delivery, but have yet to put it through it’s paces.

This is a very nice dividing head for the money. Pretty well finished and smooth operating, very little lash in the gearing.If you were thinking to use an ER32 chuck in the headstock taper note that the taper is #2 Morse not #7B&S as stated in the specifications. That is really good news given that the ER32 chuck adapter for #2 Morse is much cheaper than the #7 B&S. They are also available with 10mm drawbar threads so you can eliminate the chance of slipping in the taper.I checked the run-out specifications and found the following: Radial run-out of the spindle nose spec 0.0006" Actual <0.0002" Radial run-out of spindle taper nose spec 0.0008" Actual was about 0.001" Radial run-out of spindle taper hole 4" distant 0.0014" Actual was 0.0025" Radial run-out of test bar with 3-jaw chuck 0.0031" Actual was 0.003"So the specs were pretty close and my measurements might not be perfect. The run-out with the 3-jaw chuck was due the the chuck back-plate (spindle nose locating diameter had <0.0002 TIR). The locating diameter for the chuck had a run-out of 0.0025". That could be corrected by taking a few thousandths off the locating diameter, center the chuck and use the mounting screws to lock it in.

It is well machined have used this dividing head heaps and haven't had a problem all run outs are spot on.Could not be happier Great product for a great priceColin

It looks fine under the three plates I got two of them same plates

I haven't actually used this for anything yet. I did however disassemble and check everything. Initial run-out was 7-10 thousandths and I was disappointed. I then installed the dead center and checked run-out and it was .0005 in. OK. that is great! I then re-installed the chuck and chucked in some ground drill rod and now run-out is .00025 in. WOW! Backlash is adjustable and was nearly perfect. The index plates look accurate so dividing should be accurate as well. I couldn't be happier with the value and the quality far exceeds my expectations. I was surprised there is no lock on the face plate to the spindle, not having used an dividing head before, I have no idea if this is normal. so while it's is possible to drive this up to 2400 rpm (its in the manual) there is no lock to keep the chuck on the face plate so turning something in reverse could unscrew the chuck. I'm not driving it so I don't care. I've paid nearly the same price for my MT-2 JT3 Jacobs chuck (super ball bearing chuck and arbor) for my drill and it has more run-out than this table.
