The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)

Sea.dog:
Are you machining just the outer face, Andrew? If so, why not mount it onto a piece of 18 or 25mm ply? From the simulation there is a lot of meat left where you could sink in screws with large washers.

awemawson:
The final version needs both faces machining, so the holding arrangement needs to accommodate accurate reversal.

Was going to cast an aluminum blank today, but got distracted by discovering a rather serious data loss - when I updated computers several months back I seem to have lost all the post processors and tool cribs set up on FeatureCAM for the Beaver Lathe, Beaver Mill, and the Fanuc Tapecut Wire eroder. Quite a lot of work needed to re-create them. It seems somehow they didn't feature on the backup list but I thought I'd done a complete back up of everything including the kitchen sink :bang:

So this afternoon I need to create another Win7 machine and hope the HDD that I put in my safe has the data on it :scratch:

Sea.dog:
Ouch! :(

MetalMagus:
Create a post with a base, like a candle stick, that you can hold in the chuck and mold the wax / plastic around it. That way you can clamp properly and machine diameter and face. Might to be more like a mug tree with arms radiating from the centre spindle to give the plastic something to react against to resist slipping when turning it.

Sean, I think I'll go with an aluminium blank - time I actually cast something useful now the Induction Furnace is back up and running . . .

. . . . BUT I've spent a couple of very frustrating days tracking down back ups on various old PC's and stashed hard drives, but NONE of them have the post processors for the Partsmaster TNC355 CNC mill or the Beaver TC20 S Siemens 820T CNC lathe. The only good news is that I think I've recovered the post processor for the Fanuc Tape Cut Model L wire eroder with it's Fanuc 6 controller (but yet to test it)

What I HAVE learnt - which is very handy - is that the Windows Backup and Restore saves it's backup as a "VHD" file which Disk Management can 'Attach' as a virtual hard disk, so that you can view and access individual files without having to restore the backup onto a machine in it's entirety .
