The LIGNO Heavy Duty Rotating Centres consists of a “rotating cup” centre that is carried by a very
strong double rowed angular bearing greased for life and will give good play free performance when
turning.
It has been designed to facilitate the use of a whole range of tool bits that can be quickly and easily
changed. Removal of the bits is also quick and easy by means of a knock out bar.
All bits have a MT3 taper and fit both in the spindle extension 815 (MT3) or 816 (MT2) as in the
revolving centres 8200 (MT3) or 8205 (MT2) Sketch 1; show the extension 815 and a 4-prong driver 821. Using the extension will give more room
for hand turning, or copy and sphere turning. The sketch also shows a ring centre 845 turning a
sphere.
Sketch 2 shows two cup centres holding pieces of wood that have been recessed to accept
The sphere when turned 90 deg.
Sketch 3 shows how a lamp foot can be drilled (long hole boring). The four prong driver 866 with the
insert 868 (peg nose) works as a counter bore/drive centre and 853 is a rotating pin centre with long
pins that allow the wood shavings to drop away before they can reach the revolving centre 8200.
Generally, long holes are bored half way, the work reversed, and the boring completed from the other
end.
Cup Centre 850 and the mini faceplate 851 can be used to make and hold home made supports for
bowls and goblets etc.
852 is an adapter with an external M33 thread and an inside thread M8 and this can be used to
support faceplates chucks etc.
The extension 815 in adapter 852 holding a chuck to turn a bowl from one side. For precise
rechecking remove the chuck together with the adapter 852 and put it in the revolving centre 8200. |
