Hello.
I'm having trouble squaring fence to tabletop.
If I square outfeed table ,infeed not square.Same in reverse.
Tables seem to be parallel with each other.
Fence does not lok as if it's twisted.Any ideas?

Thanks,Bill

I'll have to take a look at a display floor bench jointer to confirm this.

But, it sounds like the Gib units, associated with the moveable table's slides may be adjusted incorrectly.

I'm assuming you have a current model bench jointer (integral motor).

I'll post back with my findings.

If you DON'T have a current display floor model machine, please post your unit's "long model number", found on its data plate.

Hi Adam.
I think I found the problem. As I put a straight edge across the fence on a diagonal
it is not flat. I'll try to get a new fence on order.

If your fence is not "too far" out of square, you may wish to lap the cast iron fence flat yourself.

I do this to tune the soles of metal bench planes from time to time.

I get a large flat surface, such a a table saw's cast iron extension table or a thick sheet of glass and attach 60 grit aluminum oxide abrasive paper to it, using spray adhesive.

Once the twist is taken out of fence, it's just a matter of working down the grits, until the desired surface finish is reached.

Look!

I can see myself!

Trivia: They sell 10,000 grit wet/dry abrasive paper.

I checked out the Bench Jointer at the local Sears store.

That's a big ol' fence on that cast iron machine!

Maybe get the twist "in range" with a portable belt sander (all wood dust having been blown out), before starting the lapping procedure, mentioned in an earlier post.

Nice machine...

They used to let large cast iron foundry pieces sit around the yard to "normalize" before machining them to tight tolerances.

Alas... much like the practice of "deburring", normalizing takes too-much time now a days.

:(
