Brilliant Rob

Thank You for showing that drill bit recycling!

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...

Again? Yes I think you have 'done it again'.

I would never have thought to 'touch' a drill bit with a lathe... looks great..thanks mate...

Next job

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

,,,, you can see the wear on the old screw in this shot ,,,, the nut is in even worse condition

Rob,

Very nice screw and matching nut.

Presume it's ACME? How did you grind your tool?

Nick

Rob.Wilson · « **Reply #111 on:** February 28, 2011, 04:27:40 PM »

Cheers lads

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

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

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

Very nice Rob.

Trion · « **Reply #113 on:** March 01, 2011, 11:02:24 AM »

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

NickG · « **Reply #114 on:** March 01, 2011, 01:36:35 PM »

Great, appreciate you taking the time to show me that. Thanks.

Hi Trion

Just heat it up and bend it , then i dumped it in water

,,, NOT THE CORRECT WAY but it works

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

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?

Well she is up and running

job done

well all bar some paint and a bit fine tuning

Knocked up a bracket to get the phase converter up off the floor and up on the wall

the wiring still needs running in

I will have to fined a new home for my hydraulic rivet closer

And i will have to make a splash back for the lathe to

Very nice bit of Kit Rob looks like you've given that lathe a new life.

Well done that man

Great Job Rob

I see you didn't waste time making some blue chips with it

Kind regards, Arnold

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!

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?

Ralph.
