Quick pic of the rino geared steppers for the BC head. 30:1 gearing and apparently even though they are wormscrew very low backlash, which will do me for now. I just have to figure out the cross roller bearings and frame for these. I have three of these I bought from America a couple of years ago, one can certainly be used for a rotary 4th axis

Now painted orange.

Cross bracing steelwork still needs to go in and the detachable mount head various tools to go on the Z. Also realised I have to strengthen the x axis plate for the Z at the back with 30mm alu bars. At full 450mm extension of the z axis there is too much opperchancity for flex. Getting there!

As a 3 axis its working fine and its happily just cut out this large map in 18mm birch for a client. Phew

Haven't atached the cross bracing across the y axis but as I lower the bed height it'll need a spacer bar at the end of the Y rails to keep the linear guides true.

Once i've finished a few jobs i'll set it up to cut the aluminium parts for the B/C head and then get stuck into the 5 axis software side of things. Might go for a rotary axis first and build up to the B/C head.
