Old CNC Router Design
CNC Router Design showing extents of travel in Y
A rigid torsion box type gantry for CNC Router. I am fond of this design because if you build the frame from aluminium extrusion and then cover the faces with plate, you are essentially creating a cery rigid torsion box that increases the rigidity of an aluminium build significantly.
CNC Router design showing the extents of travel i X axis.
A bridge inspired gantry design for a CNC Router.
A design for a CNC Router than can be bolted to the work sheet or the stock material prior to machining.
A different style of CNC Router design that allows the Z axis to sit close and tight to the gantry. To achieve this the ballscrew is mounted on the back of the gantry through a gap in the Z fascia.
Exploring an alternate design for a CNC Router.
A Basic solution for a CNC Router Z axis design.
CNC Router Z Axis Concept Design

Concept rending of a CNC Router Design Proposal.
3D Concept Rendering for a CNC Router design including a rear mounted X Screw and the ability to machine stock clamped in a vertical position.
Extemely basic view of the back plate assembly of a simple Z Axis Design.
The finalised design I went with for my proposed CNC Router.

Surface Plate Delivery
The Base that came witht the granite surface plate. It was originally painted a green colour but I cleaned it up and gave it a nice coat of black paint to match the black granite.
The Crown Grade A Surface plate measuring 1200 x 900 x 150mm.
Granite surface plate with lifting straps ready to try and lift it with a mini digger.
When the Mini Digger proved insuffient we drove it round to a trailor yeard in the village to be lifted with an FLT.
Granite all mounted on the stand and loaded onto the trailer ready to take to its final reasting place.
The angle of this photograph make this setup look quite small and humble. It is however anything but!
Fork Lift Truck lifting of the Surface Plate ready to mount back onto the stand.
Temporary castors fixed to the base to make it easier to move around whilst work was being done on it.
The stand loaded up to be taken to the trailer yard. The stand on its own is surprisingly very very heavy. I am not sure if they fill the box section with sand, but it feels like it.
Home James! Please spare the horses!
Planned to position the build close to the garage door to be able to move it in and out easier if neccessary and next to the window for natural light during the majority of the build.
Time for the hard work to really begin on the DIY Granite CNC Build.
How the Surface Plate was delivered from an engineering company in Ireland to North Lincolnshire in England.
Sensible to package this with the granite on the bottom of the pallet, but leads to another challenge of getting it lifted up onto the stand. Even a few people, i don't think could have dreamed of lifting this one by hand.
M22 Bolts on five plates on the top of the stand for levelling adjustment and calibration.
Mandatory Child Labour utilisation.
This image highlights just how big this surface plate is as it almost covers the footprint of a standard CHEP Blue Pallet.
