I will have to make a new nut mounting block as it looks naff as is  :coffee:


Rob

I agree  :poke:

Should be playing catchup in a couple of weeks with my VMB.
Got rid of that big TOS lathe [ well hiab truck comes in the morning 8:30 to drag it to the scrap yard ], problem is the debris left from the move.
There must have been ten big tins of "useful material - come in handy one day " under the lathe. Trouble is it's been there 10 years.
Started to sort it out and thought **** it, don't have time for this so threw a big Edgwick tool cupboard on its back and shovelled the bloody lot in, got to borrow a 3 tone fork truck in the morning, mine won't lift the bastard.

Got 40 metres of 2" box section coming tomorrow to make a new bench for the small CNC's to stand on, 4 CNC's on small production work will earn far more than this big old lathe and a lot easier.

Interesting John ,,,,,,,,,,,,,,and what will ye be making with 4 CNC'S ?  :dremel:

you will probably have your VMB ,,,,,,,,,,,,converted before I  :Doh: 



Made a start on the Z axis bearing mount ,,,,,, chopped a wee bit of one of my large lumps of scrapbinium .


Slapped it in the CUB lathe ,, for turning and boring ,,,,,,,,,,,,ruffing shot.


And a few hours later ,,,,,,,,,, all the turning and boring  done .



Enough for today ,,,,,,,,,,,,,i will stick it on the mill tomorrow .

Rob,
Don't waste your time on that CNC conversion. Start making and selling those chrome camera lenses on Ebay.
Gotta be a big market for them

Can we have a competition to guess what he is making ?  I bet he is going to make lenses like on your camera rob because he has always dreamed of having a finish like yours :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: or maybe he can already

I think Rob's secretly popping out and buying these bits. There's probably a massive pile of scrap behind his workshop...  :lol: :lol: :lol:

I did not get as much done to this today as i would have liked  ,, i had a few other small projects to get out of the way  :dremel: ,,,,,, milled up the edges of the block as i had just left them  ruff sawn as the job was gripped in the four jaw for turning .


now it fits into the knee.

turned up a gauge from a bit scrap bar , to gauge the fit between the lugs .

Grabbed a couple of hours in the shop this afternoon , machined the tenon (cant think of better word ) on the block . This is were i used my precision scrap gauge to get the distance between  the shoulders machined to the  correct size .

One shoulder machined finishing cut on second shoulder . set gauge on parallel ,same one first shoulder is sitting on , set hight gauge to zero.


Measure off second shoulder ........0.12mm to machine off .


Machine to size .


Jobs a good one .


Still more milling to do to the block ,,,,,,,,save that for another day .

Well done, a shame the block cant be seen on the finished machine. Maybe you should put a window in the machine, so it can be seen from the outside  :)

So, you're going to mount this machine on its side and lay down on the floor to use it, right Rob?
Else, how will anyone be able to see that block?

Aahh shoot,
No way I can compete with this, anyone want to buy a load of workshop bits and pieces that just look ordinary ?   :palm:

Decided to take up ju-ju doll making in bulk.

Holy fluff! Every machined piece looks like is going to end hung on rap artists neck and not hidden into depths of a lowly machines. I haven't seen such a nice silver plating on jewelery on long time.

I'll go fishing and if my machining does not improve I'll take up knitting or crafting garden fourniture ( I actually have to make two tables, four benches and such in a hurry). Envious mumbling, gruntting and sulkking.......replacing lawn with concrete slabs might be my calling from now on.

Thanks lads  :palm:,,,,,,,,, BLUSH   :beer:


Made a new Y AXIS nut mount today ,,,,,, as i jut could not leave/use the other one . :palm:

A bit RT work required  :ddb: :ddb:






Looks a bit better now.



Plenty of room for the pulley and bearing adjuster nut .


Now i will need to re-bore the hole for the leadscrew  to pass through the knee casting ,, as is looks like they used a rotary rat to chew  it out  .
