# Help with Jointer

• posted on May 24, 2004, 9:45 pm
I am trying to joint some 72" long Ash planks. I have a 6" Craftsman jointer (their benchtop model). I have jointed short pieces of hardwood, but these longer pieces are not working out so well. In fact I have ruined a very nice piece of wood.
Can someone explain the best way of jointing these longer boards to me? Buying a larger jointer is not an option at this point and I really want to use this beautiful Ash wood.
Thanks,

Assuming you really need your final pieces to be nearly 72" long and you are jointing for glueup and not flattening, a router with a straight bit run between the two pieces to be glued up will produce a perfect glue joint. Of course, you must clamp the two pieces to scrap so that they are about 1/8" to 1/4" less apart than the router bit width at the widest gap and use a straight edge clamped to the whole mess to guide the router so that 1/16" to 1/8" will be taken from each edge in one pass.
If your final dimensions are much less than 72", rough cut the work slightly longer than the final dimension before jointing.

1) Sight the edge to be joined and determine high spots.
2) Remove high spots to approximate straight edge. I prefer to take the concave edge, remove the ends by straddling the knives near the middle, then joining out both ends. You can do convex edges, too, but they demand a bit of forbearance, You take short passes JUST over the middle, lifting before the ends.
3) Join the full edge.

First, it isn't going to happen on a bench top jointer unless you get extremely lucky. So forget that. Rule of thumb for length of stock is 1 1/2 times the length of the bed.
The best way to accomplish the job if you do not have a jointer with sufficient bed length is to use a hand plane.

With a "bed" length of 24" ?
Work a bit on theory, and you can pick up the practice on the jointer.

Ok, what ever the hell that means.

jointer
I also have a toy jointer. No way it will ever do 72". What I have done successfully with 50" (never tried longer) is to rip a edge, and then run it on the jointer set to 1/32nd. It works fine, assuming you have a table saw that cuts straight.

I've done this many a time on a 4' long, 6" jointer.
Use some sort of support at each end, like a roller stand. Remove the obvious high parts from either the convex or concave end by jointing only those areas, with the jointer or a hand plane. The last step is to joint the whole board.
Be very careful attempting to rip a curved board on the tablesaw. As different parts of the board touch the fence, ugly things can happen, in a hurry.

Good for you. If he had a 4' long jointer, he wouldn't need to ask advice.

How short is this thing? By 4', I mean total, not each bed.
I thought I did provide some advice.

I believe the OP said he had a Craftsman benchtop model. If it's the one I'm thinking of it's even shorter than the Delta J160, which is 30" overall.
