Grandson had his 6th form meeting at school last night and I'm working like crazy getting ready for the Warwick show so every thing is on hold until a week on Friday.
I didn't know about the meeting until too late.
Good news is the ball screws are in, not bad 9 days from China and under the radar as well :wave:

OK, catching up.
Tuesday was out this week because of the show so only Friday available.
Now got the drawing for the spindle from the previous sheets so lump of metal cut and front bit of the spindle machined.
Simple machining, bore the taper , thread for the nut. Next bit is the crucial bit and it's stood me in good stead making quite a few similar spindles.
Remove from the chuck and replace with a bit of Scrapbinium [TM ] turn this down, in this case to 16mm so the largest ER25 collet can grip on it.
Then carefully drill the tail centre hole, do this at low speed so the shaft doesn't whip, once the centre has been drilled and supported the shaft can be belted down to size.
I tend to turn everything down with 1/2 a mill left on for final cutting, the reason behind this is that the shaft is constantly getting hotter as you block the bulk out. Once cool then reset the tail centre as it will have moved moved under expansion and turn to finished size.
This is state of play at the moment.
I need to make the new end housing up, do a quick assemble, check for run out then send for Tuftriding, then final assemble and test run, hopefully by the end of this week and I can get back onto the main frame fitting screws etc.
