Details:
Hi all , ive not posted for a while as workshop time has been limited , but after getting back to some machining I decided that I'd had enough of the workout I get when using X Axis hand wheel .

I began investigating why the hand wheel is stiff , loosened the X Axis Gib screws and that helped but created another issue as I'm not sure how to set them back to normal ?

Anyway ended up removing X Axis screw completely to inspect it and its fine , though I realised that the lead screw has no bearings at the hand wheel other than thrusting up on the metal bracket . Id read somewhere they had tapered bearing but not the case.

Anyway I have had the idea to use 2 thrust bearings on either side of hand wheel to ease the force required to turn it as these have to improve a metal to metal friction fit .

The reason I need help is firstly I was hoping someone has removed this nut before as I've tried backing it off but it feels tight , thought id seek advice before snapping something and causing a major issue .

photo supplied highlights the nut I want to back off to create space for 2 thrust bearings .

second issue is the X Axis Gib screws , has anybody ever adjusted these on a Alex or a Deckel FP1 ?

There must be a method of adjustment though user manual does not cover Gibs , maybe someone has a Deckel manual with more detail ?

Hope someone out there has some positive advice
