Eric. Posted June 27, 2012 Report Share Posted June 27, 2012 Changed my knives and now I've got slight twist in my jointed boards. Calibrated the same way as always. Can't figure it out. Point out the obvious thing I forgot to do real quick... Quote Link to comment Share on other sites More sharing options...
knotscott Posted June 27, 2012 Report Share Posted June 27, 2012 Are the beds coplaner with each other from front to back? Quote Link to comment Share on other sites More sharing options...
Vic Posted June 28, 2012 Report Share Posted June 28, 2012 I used a very long straight edge to adjust mine and had it going diagonally from the very front corners to the very back. 'Took a bit of messing with the cam adjustments, but was able to get it dead on coplaner. (null) Quote Link to comment Share on other sites More sharing options...
Eric. Posted June 28, 2012 Author Report Share Posted June 28, 2012 The longest straight edge I have is 38", and it shows that I'm coplaner every which way. Maybe I need to buy a longer one. Has never been a problem in the past. Quote Link to comment Share on other sites More sharing options...
Vic Posted June 29, 2012 Report Share Posted June 29, 2012 Well, I would say you're good on the tables. How are they to the cutter head? If that is dead on, I start to think it is technique. I've managed to make wedges in the past, but not to introduce twist. (null) Quote Link to comment Share on other sites More sharing options...
mlingenfelter Posted June 29, 2012 Report Share Posted June 29, 2012 How long a board are you trying to flatten? The longer the board, the harder it can be get flat. Your evaluation of the board and technique will play a big part in getting a board flat on a Jointer. If you are new to jointers and planers, Hendrik Varju has a great DVD set. I learned quite a bit from them. His DVDs aren't the cheapest, but nothing is left out. It's almost like taking a class from him. http://www.passionforwood.com/ Mike Quote Link to comment Share on other sites More sharing options...
Pbmaster11 Posted July 5, 2012 Report Share Posted July 5, 2012 I have attached the manual for my jointer... I cannot find any instructions on how to make the tables coplanar... from what I can see my outfeed is drooping causing my problems.

Your jointer is not a parallelogram jointer, so the technique to set the tables is different. What you need to do is set shims between the base casting and tables until they are coplanar. You'll want to set shim the outfeed table because you'll be adjusting the infeed table to change the depth of cut - the outfeed table doesn't move. Parallelogram jointers are much easier to adjust for coplanar. (ull) Quote Link to comment Share on other sites More sharing options...
telliottosceola Posted July 8, 2012 Report Share Posted July 8, 2012 Hey Folks, Im wondering if my jointer is coplanar or if a subtle dip in my outfeed table is causing the problem. I was jointing some pieces of African mahogany and ended up with rocking chairs trying to joint 1 edge. The more I run it over the jointer the more extreme the hump on the edge gets. My first thought was my outfeed table was sagging but I checked and infeed and outfeed seem coplanar. Then I sat the straight edge on the oufeed table and found a dip right in the middle about .0025", would that be enough to cause this problem?

flairwoodworks Posted July 8, 2012 Report Share Posted July 8, 2012 A low outfeed bed or a dip in the outfeed bed would cause a concave (hollow) section, not a hump. To remove a hump with a jointer requires careful technique. It would probably be easiest to cut it close to straight with a bandsaw or tablesaw before jointing.
