Thanks Ward
My lathe is an old Myford with no auto feed just a nice Bernerd chuck. I have a big single phase Chinese mill/drill with a round stock with plenty of tooling (just need a decent adjustable angle plate). Most of this has been done with hacksaw and files:-).

In the UK the x and y axis are the Horizontail axis and the Z is the vertical axis and as far as I am aware this is the excepted convention, I was a little confused at first as to what you were refering to with regards to axis orintation but now understand.

It is confusing....I think that the convention in naming an axis is that Z is in line with the cutting tool, which is in this case the wire.

Left XY and Right XY is how GMFC is set up which is what I have been using for years. I am not sure about other programmes. I have started to think about other programmes but will stay with GMFC as long as Gilles keeps supporting it.

Started on the bearing mounts for the X axis threaded rods. I decided to have bearings at both ends because the motor coupler is not true or very supportive.

Machined the ends of the threaded rods. In spite of the threads they true up fine in the 4 jaw chuck:-)

Nice.

You going to use a bow or spring setup for tensioning the wire?

Hi Ward I use bows of different lengths as I move the towers a fair bit depending on the panel size. I will make all new bows for this machine as I have a plan for integrating them better.

Got the first X axis done. I expect some fine tuning will need to be done once I get the motors turning but it seems to be nice and smooth at the moment. I've nearly used up a 200 piece jar of 4mm CS screws and 100 5mm bolts.

Wow! complex and careful work.
Seems like the Hobby is building machines not merely melting up Foam construction insulation

I love the wide range of skills this obsession requires. Design, woodwork, metalwork, composites, electronics, flying skill and probably a few more.

Got the second XY done today. Now for the bow mount and the wiring.

Made the bow holders today. One end will remain relatively fixed and the other end will slide to allow for thermal expansion and panel taper. Measured thermal expansion of my longest bow, 1670mm wire .25mm inconel. It was 6.5mm.

Got the bow stay on. I need to find some 5-6mm stainless rod for the bow legs which will slide in the slot.

When you get done I would be willing to do all the testing for you. Of course to do a proper testing job may take "several" years. At the completion of the testing period, I will submit a complete report on the operation and any improvements that will make it a better machine.

PS a typical report goes something like this.... It worked great.
