The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
awemawson:
And the good news keeps rolling in :ddb:
The nice chap who sold me the probe has been looking though his files and has emailed me with what appears to be a complete set of back up parameters from this machine for the 820T controller, the PLC, and all the various off set corrections and pitch corrections. He has even included one or two examples of programs.
Funnily enough today I was looking through his programming course notes hand out that he had sent with the probe, and noticed that in the very first example they give they had printed an error - simple positioning to turn a stepped profile - it had the set up bits like metric measurement, absolute positioning etc then went straight into a list of co-ordinates without issuing a G00 or G01 move command, so it could never have worked. I hope they found that on the course :clap:
At last I've found a weight for the machine - 6.25 tons :bugeye: and at vast expense have commissioned a professional machine moving company to collect and deliver using their enormous hi-ab equipped lorry - only problem now is that the seller is proving elusive and not answering phones or texts.
Meanwhile I've been offered another Beaver TC-20, slightly younger but in far worse condition cosmetically for less than it's costing to MOVE mine ! Shame to miss it, as obviously it would be an excellent spares 'Christmas Tree', but again I'd have to move it. Tempting as I have room for it and it has a full set of documentation. I'll try and liberate the documentation at least, or just maybe buy it and strip it on site though the removable chunks are pretty sizable on their own .
. . . any volunteers for a day out in Birmingham helping me pulling a machine apart in a controlled fashion !
It's not quite identical being fitted with a different tool turret and machine control panel but the Sinumerik controller is fundamentally the same. Picture to show it's not as nice as mine :ddb:

Was that on ebay last week ? if so they wanted £100 loading fee , I am not surprised it nod not sell .
awemawson:
Yes Jeff, and it's been re-listed. He is paying huge warehouse fees and is getting desperate poor chap.

A word to the wise....
...be extremely cautious with that seller.
I bought my first Interact 1 Mk2 machine from him. It was described as being in "good working order", having a TNC151 controller, and - since the photos on eBay showed it outdoors - I specifically asked if it was stored indoors, to which I received an affirmative.
When my man went to pick it up, it was still outside, and soaking wet (it's Birmingham, it rains almost as much there as in Manchester).
The tools, when I got them, were all full of water.
The controller was a TNC150, not the promised TNC151 (ok, I can maybe understand that mistake).
Once I'd given the machine a week in a warm place to dry out, it "mostly" worked. The motor cooling fan was seized (from the rain, probably) and the coolant pump didn't work.
Fortunately, I managed to acquire the machine I still use to this day, for less money, later on; and shifted the less good machine on for what I paid for it (to a chap who was happy to take it at the price even with the faults described).
It's highly unlikely it's costing Bilal anything in warehousing; chances are it's still at it's original owner's place, and he's screaming to get it out of the bl**dy way...
awemawson:
I speak as I find, and to be fair the chap has been very helpful to me - he made a special visit to the warehouse to photograph the documentation for me, and try and find a weight for the machine. If it doesn't sell on eBay this time round I've no problem getting back in touch with him, but obviously I will keep your caution in mind Ade.
There's good and bad in all of us I suspect :med:
