Solved the binding, the idler on the end of the spindle for the lead screw drive was loose

Finally got the lead screw and reverse gear box working nicely, had to resort to using the Halifax gearbox with the atlas gears, 1st drive shaft and selector nob and plenty of grease.

I tried machining the small pieces of ball screw that Gary gave me but not much luck

I thought the tool post I had was very sturdy but seeing it move out of the way instead of cutting the screw proves otherwise.

So I'm going to put the tee slot table on, get a QCT and some new carbide tooling

The only problem is that I didnt get the gib. So my question is how can I get around this? will a small strip of brass be ok? something in the back of my mind tells me that only precision ground steel will do
