Taper Turning Attachment - Mk2
Taper Turning Attachment - Mk2
Ref: HK 1320
With a nominal 10" (250mm) working length, the Taper Turning Attachment Mk2 is conventional in so much as the design follows accepted practice. It does, however, have some design features which we believe have not been generally available. The attachment bolts to the rear of the lathe bed. Myford supply their 7 Series lathes with holes already drilled and tapped to accept such an accessory but adaptation of other beds may be practical.
The slotted link is bolted to the rear of the cross-slide. Please note that this link does not stand proud of the cross-slide surface in any way, thus the whole of the boring table area is free for use at all times. Once the attachment has been fitted to the lathe, it is left permanently in situ, and the lathe can be made ready for taper turning in a very short space of time. All that is needed is to release the cross-slide feed screw, bring the top-slide into a suitable cutting position, clamp the slotted link to the guide bar using the ball handle and, apart from placing a suitable tool in the tool post, setting up is now complete.
For general taper work the guide bar is easily adjusted by a fine pitch screw. Accurate tapers, as required for say Morse taper tooling, demand the exact position of the guide bar to be established. A revised precision setting micrometer, that enables quick, extremely accurate angular settings is detailed in the drawings.
The kit includes LM 25 Aluminium castings for the main bracket and slotted link and a phosphor bronze casting for the slide. Steel parts, including precision ground flats are provided, together with fasteners, drawings and instructions. The accessory costs well under half that of a conventional, off-the-shelf product, not having the advantages of this new design.
