So with the new cable here took the connectors apart. The ones on the Chiron were the screw version, so I was a lip bit disappointed when found out the these ones were crimped. After a quick research I found that screw inserts were cheaper than being new pins and fitting crimp tools. But I wanted to move on so I soldered the old pins to the new cable. It took a while but went quite well:






this it was it looked like after shrinking some tube over the soldered area:



and there was more than enough room in the connector so the thinner parts didn't give me troubles when I closed the connectors up.



so after three hours of soldering both 24 pin connectors were done:



This week the leveling feet fo the lathe arrived and a heavy duty skate board together withe some accessories which should help me wo get the lathe moved to her final resting place:

Did some preparation to move the machine. First I marked the position where I want the machine to be.

Next I drilled a hole in the concrete to glue in a towing point. The allthread is just there to keep the nut clean till the glue is dried.

File Attachment:


Last step for today was to rest the rear end of the machine on a 1to skate board. And adjust the pallet in the front. Now I need to wait for the glue to cure.

Thanks, today I got stuck. I just wanted to make some clanup when I saw that the gib of the cross slide needed some adjustments so I pulled it and it was quite gummed up, so I decided to remove the cross slide. So I removed the screws which hold the cross slide on the ballnut. But it didn’t move. So I removed the multifix. A few drilled out bolts later this bastard was off but no further bolts underneath. Then I found two tiny set screws which I removed and it turned out that they belonged to plugs which I pulled then and found two dowels underneath. I tried to pull them but gave up after ten broken allthreads. Which I used with a long nut to try to pull them out.

I also flooded everything with thin oil.

Anyone a good idea how to pull dowels?

Thanks Patrick

I feel for you. That sucks. My ideas be:
- drill right through, thread the end, screw in a grease nipple and use hydraulic pressure to press them out from behind?
- Weld a stud on and use a slide hammer?

usually this alignment pins get pulled with an "slide hammer"

www.contorion.de/handwerkzeug/kukko-stif...wfEpItgaAvNvEALw_wcB

I removed them with an long threated rod, double long nut, self turned ring and used an old SK50 Holder as slide ballast.
I've got them all out and my nef is fully rusted, because of standing outside for more than ten years....

Next try next fail:

File Attachment:


I guess I build my self a sliding hammer or see if I can get in there with my tig torch and see how much higher the m10 rod will launch compared to an m6

Thanks for you suggestions. I‘ll also will see if I can get a m6 grease nipple

Cheers Patrick
