I was wondering if anyone knew of a company or anyone in Adelaide that does surface grinding / could flatted my jet jpt-410hh (not a 310hh) beds. Bed dimensions are 810(l) x 415(w). Over the past couple years they have been getting worse with time due to the casting moving and has now developed a twist and dish (dish was already there) in both infeed and outfeed tables. Where as the thicknesser bed is fine. This has gotten to the point where it is significantly having an affect when jointing boards.

I went down to Apex Engineering and got quoted $1000 for both beds which I cant afford and thought it was a bit over priced.
Any help is welcome. Thanks.
