There are plenty of accessories that can be made for the VDH, and some are required to make the head in the first place.  I've listed them here in the order they were made.

LA faceplate and Myford spindle adapter

A light alloy faceplate - this is an unmachined casting which can be obtained from Hemingway, and makes the job of drilling the plates much easier.  A steel section is glued into the front of the faceplate to allow work to be bolted through the centre of the plate.

Faceplate1 07-Apr-2005: The casting being trued up in the four jaw chuck.  It's in the chuck back to front, as this will allow the thread and recess for the register to be machined.
Faceplate2 The back of the plate and outside of the boss have been machined, and a boring bar run through to increase the diameter to a size suitable for cutting the 1-1/8" x 12TPI thread.
Faceplate3 After threading and finishing the recess to size, the faceplate can be removed from the chuck and screwed onto the lathe spindle.
Faceplate4 A recess has been machined in the front of the faceplate to accept a steel disc.  The disc has been turned down to 1.6" diameter from a small section of 1/4" steel plate - this will now be pressed into the recess and secured with Araldite.
Faceplate5 14-May-2005: This is the retainer which will pass through the centre of the plate and hold it onto the faceplate.  Before parting this off...
Faceplate6 it can be used in situ with a suitable spacer to trim up the plates to the same size.  The edge of the plates can be chamfered at this point too.
Faceplate7 Pictured here the Myford spindle adapter with the LA faceplate and the plate retainer.  The LA faceplate has had three holes drilled in it to take 1/2" x No.6 screws to hold the plywood sheet on.  Nothing special about the Myford spindle other than it was made from two sections of bar glued together to cut down the machining time.

Headstock dividing attachment

A very simple but effective attachment that allows headstock dividing to be carried out.  The gadget consists of three main parts - a 1/2" shaft with a 2MT end, a 3/4" sleeve with a chamfer on the end to fit the spindle, and a support bracket.

HDA1 18-May-2005: View of the attachment before the dividing head is coupled up.  The base of the support bracket is held to the quadrant using the pin from the Myford catchplate (5/8" diameter).  The sleeve could do with three 2BA grub screws near the lathe end to prevent eny slip.
HDA2 With the Versatile Dividing Head attached.  The assembly is fairly solid, and works well.  The only downside is the spindle locking lever is on the opposite side, although access is very good so it doesn't cause any major problems.

2MT sleeve

A simple sleeve that plugs into the 3/4" bore and accepts 2MT tooling.

Sleeve 28-Dec-2006: The sleeve pictured here with a 2MT / ER25 collet chuck.  I'm standardising on ER25, so the sleeve (and collet chuck) allow me to hold circular items up to 16mm in diameter.  The sleeves described by GHT are useful in that they allow materials through the bore, but this setup here will probably cover 99% of what I need to do.
