Is it just me or is there really a coherent interference pattern on those bores they look SO TRUE!

I never seen rotary rat tool but it must be a chinese version of rotabroach? Seen plenty of those holes thoug.

Very nice. How did you centre that Y nut mount on rotab? Did you had a bespoken spacer that fitted inside the mount bore?

Fabulous work as always Rob - your hidden-away bits look better than my proudly-on-show bits 

I see you've craftily numbered all your clamps "3" - this must be some clever Geordie system?

[Rob.Wilson]

Thanks Lads 

maybe its the coolant - is it IrnBru I wonder ?

cheers / Dave

Hi Pekka ,,,,,,,,,, The finish in the bores is straight from the lathe , i used a tipped tool    ,,,,, To set up the job on the RT i just clocked the bore into the RT axis .

I see you've craftily numbered all your clamps "3" - this must be some clever Geordie system?

Cheers Ade   ,,,,,,,,,,  no Geordie system ,,,,,,,,,,they came like that 



Well i did a bit more tonight    set up the knee on the mill for boring .


Picked up new centre .


Used a hole saw to remove the bulk of the material , quickest way to do it .



Finished to size with a boring head .




It needed boring this size for the nut to pass through when fitted to the screw , also the bore will be used as a register for the Y axis bearing block .

What did you use to chamfer the edge Rob?

[John Stevenson]

What did you use to chamfer the edge Rob?

Knowing Rob, probably a plastic fork from KFC.

Bugger it, down to some serious Juju doll making, this is pissing me off....................

[Dean W]

Rob, you need to have the police provide protective custody for you each night.  Else, the Chinese are going to
kidnap you and torture you for info on how to do these machines right the first time!  Watch over your shoulder, mate!

[Stilldrillin]

Well Lads.......

It's 07.20, and I've just clocked in, before breakfast, at the start of an unsure day.

I just have to say, what a boost/ lift, this continually developing posting gives me........ 

Thanks Lads. Your humour/ friendship does more than you realise......

whats happening today David ?

[Divided he ad]

So I read the title of his tread and thought "Not really into CNC..... ahh, I'll take a look,"

So I did, I read through it and thought... "nothing special, just a few little repairs to an old machine"


Dunno what's wrong with some of this lot eh Rob?    Like no one had ever seen a machine repaired before 






Ralph.

I'm pretty sure he's got a robot in there John:



There's no way that's a human hand... 

[John Stevenson]

Probably is because they look like the gloves some bastard pinched out my workshop some while ago.   


Getting serious for a minute these gloves are what's know as PU gloves, do a search on Ebay. They are a light weight fabric glove that has been sprayed on the front with some thin plastic, the back remains open weave.

Now years ago in an earlier life i used to work on trucks, bloody hard and heavy work, we were supplied gloves but it was impossible to work in them other than for lifting and grunt work, even then it wasn't comfortable and i have always been against gloves.

Fast forward to 2 years ago and that bloody cold winter we had, one of the guys at the body shop across the road gave me some of the PU gloves and what a boon, warm hands and you can even work with small screws etc.
I am now fully converted and buy these all the while, they last ages anyway and I keep the dirty ones for dirty work, shop around and they cost about 80p a pair.
A pair lasts me probably the best end of a week and that's full time use.

If you get a chance to try a pair do so, I never regretted it and others I have put onto them also swear by them.

OK back to the normal program and keep taking the piss out of Rob. 

[HS93]

Mr Stephens  have you got a picture of the back of a pair what writing they have on the ones you use I have found so many types on the net and also a supplier up the road from me so it would be handy to make shore I get the right ones as the blue nitride ones I use when working brass make me sweat like a donkeys D***

Peter

[John Stevenson]

Peter,
Who's this Mr Stevens ? it's Stevo, John, dipshìt, or cretin to you.

Have a look at this picture.

http://www.ebay.co.uk/itm/150552556116

Don't buy the black ones, the grey or blue are better as they seem to be thinner on the coating, the black are more heavy duty.

[HS93]

thank you for that John, sorry about the Mr Stevenson , but I was always  told to respect my Elders I will call you John now

Pete

[AdeV]

Thanks John, I've been using white or blue nitrile ones like Peter, they are OK but make your hands sweat, and leave chalk all over your clothes...

I'll give the PU ones a go. If they last you a week, they should do me for about 6 months/pair...

[John Stevenson]

I can't get on with the nitrile ones, put a pair on and rip them off with 10 minutes, the PU ones I wear all day and it's now got to the stage where I feel lost without a pair on, even in summer.

If someone had told me two years ago i would be wearing gloves I'd have been the first to burst out laughing.

Ade, might only last you as long as me if you are working oily stuff, believe it or not my job is quite clean in that it's all new metal and most of the time cleaned components.

In hard conditions I wonder what nitrile over PU would be like ? the problem with nitrile is when it's next to your skin.

Might walk over the road to the body shop and scrounge some nitrile ones to try out.
Mind you thinking about why i don't like nitrile is they stick to handles when you are cranking away on the machines

  been there crank knee up ten turns ,,,, bastard hand stuck to hand wheel ,,,,, wined knee down ten turns

  Wish hey would Dean ,,,,,,,,,,i love noooooodles 

What did you use to chamfer the edge Rob?

Hi Ade ,,,,,,,,,, i used a chamfer bit i ground up from a bit HSS .





Enjoying the crack lads         PS me thinks JS has a rubber fetish     


Rob

[Dean W]

PS me thinks JS has a rubber fetish   

No doubt.  But then again, who doesn't...?

[doubleboost]

Hi
It is looking very good

Rob gave me some of those gloves
The next time i bore a hole i will wear them 
They may help me get it the correct size 
John

[Stilldrillin]

Those gloves? I've just ordered two pairs! 

Correct size holes don't attract me. I just want the shiny components.......

Phew, thanks mate that was close, can breath again now............................

[John Stevenson]

Anyway sod all this stuffing about with old lumps of metal converting into what not.

Had a brain fart today and ordered a new laser cutter, let see you make one of those Wilson.

Not a problem ,,,,,,,,,, A bit tape rapped around a laser pointer,for a precision fit , rammed up the mill spindle will do the job    ,,,,,,,,, that should do the trick ,,,, bet mine cost less 


How way then ,,,,,,,,,,,,,link to new toy

Rob

Nope, have to wait it's on the secret list 
If I posted the link now I'd have to kill you.................... 

[Rob.Wilson]

Or maybe ,John , just maybe ,,,,,,,,,,,,my laser pointer stuck up the mill spindle is better 


Spoil sport ,,,,,,,,,,,,,,
