Gents, I would appreciate any helpful feedback or links. I just purchased a used General jointer. I now realize that I didn't check everything before purchasing... my bad. Anyways, here are some of the issues.
1) Both tables are as flat as I can measure (length, width, diagonal). I can get a 0.0015" feeler gauge under the straight edge. Check.
2) Tables are coplanar as far as I can tell. I cannot get the 0.0015" feeler gauge under the straight edge except in one diagonal position. Check.
3) There are nicks on the blades. No big deal. I will change them.
4) Here is the problem. The fence is slightly concave I can get a 0.007 feeler gauge in the mid point of a 24" straight edge (ditto with the 50" str. edge). I think there is also a twist on the fence. I can get one side of the fence square with a table, but not with the other table. I can get the 0.002" feeler gauge between the fence and the square. Temporarily, I have set the outfeed side of the fence square.
I will recheck the tables to make sure that I didn't dream the coplanarity, and then run some test pieces. I'm fairly certain that I have a twist and a bow on the fence. I don't see issues face jointing, but definitely with edge jointing.
Does anyone know where I could get the fence regrinded?
I have also thought about adding a MDF subfence that can be shimmed square and flat. I can attached with bolts or magnets.
Your comments appreciated.
