Leveling Denford lathe - has no levelling screws?
loply:
Hi folks,
I'm trying to level (untwist) the bed on my Denford Viceroy lathe, but it turns out there are no leveling screws underneath the bed!
It's cutting quite a larger taper when I chucked up a 75mm x 200mm aluminum test bar. I haven't checked the head alignment but as I know the bed was removed from the cabinet by the previous owner, I'm assuming it's a twisted bed.
I lifted the bed off the steel cabinet today and found it was simply bolted down, one bolt in each corner, passing through a clearance hole in the chip pan. One of the bolts was missing altogether.
This is actually the second Viceroy I've owned and the previous one had a double-threaded widget in each corner which you used to jack the bed up and down.
Any idea what gives here? It looks to me like it was this way from the factory, because the chip pan holes aren't threaded. Should I just resort to using shims under one corner? Any idea why there are no leveling bolts?
Would appreciate any advice, would like to get this thing cutting straighter.
Here's the rubber washers which were squished between the chip pan and the bed:-

I do believe that the Denford Viceroy is mounted on two feet at the headstock and one at the tailstock. No way to adjust for twist.
loply:
Correct about the number of feet, but as I say my previous Viceroy had a "screw within a screw" system for twisting it, and the drawings and various bits of info on the internet all indicate this is the case too.
I'm just a bit mystified as to why it doesn't have any leveling feet, and if the designers somehow thought that it shouldn't need leveling.
I guess I'll just design & make some though? I suppose I only need one really... I can bolt three corners down tight and just use some kind of jack screw on the remaining corner?

I would have thought the bed was more rigid than the stand?
DMIOM:
No help for the twisting issue but those 'squished' washers look to me like those used to seal the heads of the nails used to secure corrugated iron or asbestos roofing sheets.
