The carriages
The Y axis cariage (Zcarrier) is below. it uses three 12mm V groove bearings which have an OD of a little over 45mm.
All three are mounted on eccentric bushes to allow adjustment
The material used in construction is 10mm aluminium. For these sorts of projects I like to tape the stock off with masking tape to draw on the design to be milled, drilled and tapped. That way any changes are easy to make and by removing the tape from places where material will be removed gives a better indication on what the final piece will look like.

This one shows an X axis support. It also shows a failed layout. As there is two of these identical parts, the measurements were referenced from this layout and re-marked on the opposing side. the two parts then placed on the mill and drilled/milled as one using the other plates' markings.
The rails are smaller on this axis to keep the cost down a little. it uses 3/8" V bearings which have an OD of a little over 30mm (just to mix up metric/inch measurements)
