 :bow: :bow: Brilliant Rob  :thumbup: :thumbup: Thank You for showing that drill bit recycling!  :clap: :clap:

 :scratch: Must it be hydraulic oil to harden it, or will other oil do ? - I have a bucket full of used 20W40 motor oil that I use for hardening silver steel...

Next job  :dremel:


The cross slide nut ,,, milled up a block of bronze , bored and screw cut 8TPI ,,, remembering to make it left handed  ::)



Still a bit of machining to do  :dremel:  ,,,, you can see the wear on the old screw in this shot ,,,, the nut is in  even worse condition  :coffee:

Rob,

Very nice screw and matching nut.  :thumbup: Presume it's ACME? How did you grind your tool?

Cheers lads  :thumbup:


Spot on Nick ,, it is 5/8 ACME ,,,,,,,,, I use the bench grinder and a screw cutting tool gage ,,, it is easier to start with a length of tool steel first as this makes it easier to hold when grinding .... grinding one side at a time ,, with the tool steel not in the bar .
 

Then put the tool steel in the bar and lock it up , then you can use the bar as a reference .
 

Then grinned the other side ,, and cut off the bit you need ,,, i use the good old dremel  :dremel:


Thought i would stick this in ,,,,,,,, just because the HSS comes straight ,,,, it dose not have to stay that way , just heat it up and bend it to suit the job in hand  :med:


Had a leisurely hour in the shop tonight  and finished off me nut  :)
 


and made a new bush for the outer end of the screw

Again very nicely done! How did you treat the HSS when bending? Did you bend it first, then heat treat and quench?

Yer an inspiration Rob; I'm a'luvin' this thread! :beer:

I noticed in the pic of the finished 2-piece bronze nut that there are 2 allen setscrews and 2 SHCS's.  Is this how the backlash is adjusted?  The 2 setscrews are adjusted to spread the pieces apart to take out the slack then the SHCS's are locked down to hold it?

Nice looking bit of kit there Rob, very interesting stuff with the repairs.... Things to try to remember (or at least remember where I saw them!)

You really do have too many skills... I think you need to send some more of them over the airwaves!  :dremel:






Just a bit of an odd question..... You said it just needs some paint... Why are all these machines covered in that bloody awful colour (whatever it is???)


What's the matter with something a little more, well, lively?
