Mdro don't sell an optical scale any more, all magnetic now unless by special orderRemember magnetic ones can be less bulky than optical
I've heard terrible things about newall recently both here and in the states.They must have got sick of the service from Newall. Shame, cos their encoders are excellent.
Already covered all these topics above i think.I have an Easson DRO on my Archdale, from M-DRO. Got the LCD console which gives graphics for PCDs and radius generation. Very very user friendly.
As to earlier question on oil, I'm using ISO88 slideway oil in the main wickfeed oiling stations (if you haven't cleaned these and replaced the wicks then you will need to) and ISO32 as spindle oil in the dripfeed oiler.
On these machines it is ESSENTIAL that they are perfectly level, otherwise oil from the big oil pot behind the back of the table won't reach the oilways for the front of the table.
Worth pointing out that The dripfeed is not for the spindle bearings it's just to lubricate the spindle in the housing.I have an Easson DRO on my Archdale, from M-DRO. Got the LCD console which gives graphics for PCDs and radius generation. Very very user friendly.
