The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
awemawson:
Having started a bit of a cleaning spree, I thought that I'd clean up behind the tailstock before I wound it back out of the way. Just as well I did - it revealed another panel that just might . . .well you get the idea :ddb:
OK panel off and guess what - hex headed button cap screws revealed - OK a long way away . . .if only I had a 30" long x 4 mm hex allen key. Well go make one my man :clap:
A bit of 8 mm rod drilled 4.4 mm one end and a 4 mm stub of allen key silver soldered in, and a Tee handle formed on the other end - worked a treat and guess what - panels "A" and "B" are now OFF :clap:
Panel "C" just has one cap screw left and is supported on wooden blocks - BUT looking again at the tailstock end of the lathe, that sloping panel unbolts and will I'm sure let me get Panel "C" off at last - but just now it's far too hot and sticky to continue !
I have a feeling that I'm going to re-design how these panels fix - maybe something along the lines of keyhole slots or maybe rare earth magnets :scratch:

Keyholes, slots or such locating features gets my vote every time. Too much slop or vibration? O-rings, NBR sealing strip or two sided foam tape (particulary god stuff, holds parts well, but comes appart with a little yank).
Magnets are good for a location where you need a repeatable force to actuate, but they are magnets really for any swarf etc. and really a nuisance magnetizing tools, instruments etc.

I suggest Dzus quarter turn fasteners. They are spring loaded, easy to use, and vibration resistant.

Pekka, I agree about the swarf attracting properties of magnets !
Weldingrod - yes the Dzus fixing are good - not sure I'd be able to retrofit them but definitely one to bear in mind.
Well it was only another six cap heads to remove that sloping panel, so off it came revealing . . . . . well not a lot! A bit of square ducting, where is the cap head? No way I could see it, but groping about I could feel it, and just about get an allen key to it, and eventually off it came releasing panel "C"
. . . .now why did I want these panels off :scratch: :scratch:
WeldingRod:
Because you NEED to know what's behind it ;-)
