Congratulations on the purchase of your ONEWAY Drum Chuck!
The TaperLock Adaptor
Packaged Separately you will find one Taperlock Adaptor. Once installed, this adaptor provides the interface between the drum
chuck and the spindle.
Adaptors are made to fit practically any spindle size. If you change lathes, all you need to do is buy a new adaptor, not a whole
new Drum Chuck. The taperlock design eliminates the possibility of the adaptor loosening or separating from the chuck body
in normal use or when reversing the lathe.
The first step to use your drum chuck is to install the adaptor.
Step 1 - Mounting the Adaptor
1.
Wipe the inside of the taper of the drum chuck body as well as the outside of the adaptor to be sure all grit and dirt is
removed.
2.
Slide the adaptor into the chuck body with the holes in the adaptor lined up with the holes in the drum chuck body. (two
holes will line up, and two will not)
3.
Thread in the M5 * 16 socket head cap screw and with the 4mm hex key, tighten them alternately. Alternate tightening
ensures that the adaptor is pulled into the taper straight.
Removing the Adaptor
1.
Remove the two tightening screws and thread them into the two tapped holes of the adaptor. They now become jack
screws.
2.
Carefully tighten alternately until the adaptor pops loose from the taper.
Step 2 - Mounting the Drum Chuck to your Lathe
You are now ready to mount the Drum chuck assembly to your lathe. It is important that your drum chuck is put on your lathe
properly. Proceed as follows:
1.
After mounting the adaptor to the drum chuck, carefully screw the assembly onto your lathe spindle. It should go on
smoothly without excessive play or binding.
2.
Screw it all the way on until the adaptor face contacts the spindle shoulder.
3.
Next, lock your spindle, and unscrew the chuck just slightly so you can give it a firm swift spin, consequently snapping the
chuck home. Alternatively use the removal lever to bump the chuck home.
What are the two set screws for?
Two set screws are provided which go in the adaptor, and when tightened, attach the Drum Chuck to the spindle.

1.
These set screws should only be used if your lathe has a hardened spindle.
If you can mark your spindle with a file, then it is softer than the set screws and these screws should
not
be tightened
down on the spindle.
2.
The set screws must be inserted in the adaptor to create a seal.
We highly recommend that if you do not have a hardened spindle, these set screws be glued in. This will ensure they do not
come out after prolonged use. If you chose not to glue them in, check they are secure on a regular basis.
Step 3 - Attach the Neoprene
The next step is to attach the neoprene to the Drum Chuck body. The neoprene is used to give a superior seal between the
drum chuck and your work piece.
1.
Carefully peel the backing from the neoprene.
2.
Centre the neoprene ring over the rim of the drum chuck (making sure the sticky side is towards the drum chuck).
3.
Next, center the former on the neoprene rubber and chuck, and press together with your tailstock. Optionally, use your
vacuum pump to apply pressure by sucking the former on. Adhesion will be instant whether using contact cement or the
adhesive present on the neoprene supplied.
