Hi all,
I have an issue with my A3-31 regarding table flatness. This seems to be a repeating topic, but I could not really find a solution. I adjusted the machine following the various tutorials and could get the tables into good alignment. However there remains an issue with table flatness, specifically that both tables are concave near the cutter head, although they are rather straight further outside. Already about 20cm away from the cutter head, the tables are reasonably flat. I filled out David Best¡®s table flatness sheet and attached it below. Caution: all values are in mm.
I don't think the flatness of the table is a problem until it affects your result after jointing/planing. You don't mention why you started to investigate this. Do you get good results using the machine?
Regards,
Jonathan
