A very nicely made George Thomas Versatile dividing head for sale. Hemingway set. Ideal for a milling machine or the Myford ML7, Super 7 and ML7R lathes. Has 3 collets and a collet nose. Spindle thread is the same as the Myford lathe spindle.

I also have the arm and centre that were not made by the maker of this dividing head. They are however nearly finished items availble to compliment this dividing head if required. Available as an addition if required.

The last two photos show a spindle drive unit and supporting bracket, for dividing through the lathe spindle. Spindle drive is for the Big Bore Myford however one could easliy make one for the standard bore Myford. Available as an addition if required.

This quality item was made by an excellent model engineer and not to be confused with the mass produced (far eastern) copies.

 

Designed by Mr. G. H. Thomas and described in the M.E. March 1979. All drawings and instructions are included in Mr. Thomas' book, "Workshop Techniques" and also in "Dividing And Graduating".

Commercial dividing heads often find disfavour among Model Engineers, because they do not always fulfill the varied needs of the smaller workshops.

In this design, consideration has been given not only to the wide range of possible uses of the Versatile Dividing Head but also to the simplification of construction. In this context it may be mentioned that this dividing head generates its own division plates to a very high order of accuracy.

Simple Dividing is by means of a spring loaded plunger engaging any of the 24 holes in the face of the main wheel. Squares, hexagons, keyway cutting and tap fluting will probably be done by this method.

Conventional Dividing is by means of the usual worm and division plate, which now replaces the spring loaded plunger. Both this and the plunger are mounted on a banjo which can be swung around the main casting to the most convenient operating position. The two division plates will allow most divisions used, including angular spacing, to be obtained.

Prime numbers or indeed any possible division outside the range of the two plates are indexed by means of the "Micro-Attachment" giving capabilities down to 1/100th of a degree! Thus a second worm and wheel are attached under the division plate, allowing calculated manual rotation of the division plate, by means of the calibrated knob at the end of the worm shaft. This rotation or correction is done at each step of the dividing.
