The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
charadam:
Andrew,
I bought one of these a couple of years back. It feeds to a laptop, so although resolution is not exactly crisp, it has done eveything from tracing cable routes in the house to reading labels on my Chipmaster lathe motor. It also reassured me about the condition of the bore of my Brown Bess.
And, its only a few squid!

Thanks for the suggestion. I do have one of those somewhere, but I was somewhat unimpressed - maybe they have improved but mine gives horrid 'fish eye' distortion and is rather low resolution.
awemawson:
Bit busy with other things today, so I set myself a nice simple objective - remove the tail stock end panels so that I can clean up round there and inspect the ways for rust and debris.
Well I totally FAILED :bang:
If you look at the first picture, the big panel "A" is flapping about unfixed at it's right hand (outer) edge, and is fixed to panel "B" and panel "C" with socket head cap screws into welded in nuts on the flange, screws having entered from the front of the lathe.
Panel "B" that looks as though it should just come out, has no fixings up or down, but is fixed to panel "A" as mentioned and to the cream main body of the machine similarly.
Panel "C" is L shaped with a return angle - again no up fixings only fixed to panel A and the cream body of the machine.
Now all these cap headed screw are totally inaccessible unless your arms are quadruple jointed and ten foot long - mine aren't !
I tried hand cranking the main carriage by turning the ball screw pulley as far as I dared (look how close that drill is to the wall of the enclosure :bugeye:) hoping something would be revealed - well it wasn't :bang:
Taking the pictures and studying them is slowly drawing me to the conclusion that the only way to get at them, is to somehow release the way covers at the tail stock end - slide them to the left and then just perhaps it might be possible to reach through, though I suspect I'm going to have to find how to move the tail stock itself out of the way - no idea how that happens - there's a crank handle, some locking cylinders and a big ram (but I think that the ram only moves the quill :scratch:)
Anyway the good thing to come out of this, is that the box ways and ballscrew on the far side of the carriage are in good shape as are the swarf covers :thumbup:
awemawson:
Well the tail stock movement question was easily resolved. I couldn't crank the handle because it has a locking detente - pull the handle out and crank away. But even moving the tail stock fully towards the headstock it is very much in the way for access to those screws behind the way covers :scratch:
awemawson:
Determined to get at the bolts to remove those panels, I started investigating inside the tailstock hydraulic cabinet below the controller. There is a wiring duct with a bolt on cover that just might give access to one screw on panel "C". So off it came - sure enough I can see the rear of the hank bush that the bolt goes into, but no way can I undo the bolt itself. OK duct cover replaced, and a clean up inside the cabinet was in order.
