Setting a planer???

Wonder if anyone can help...

 

Im trying to set up my planer on a combination machine; when attempting to plane one edge I am finding that the edge arcs inwards towards the middle... can anyone offer any advice to why this may be? I'm sure the blade is set correct however I am unsure with the alignment/ height difference between the feed and exit table tops... could this be the root cause???

 

Any advice welcomed....

A little more information about the planer may help with people coming forward with advice ie; what make and the model maybe a diagram of what it is doing to the wood.

To start with are the blades adjusted correctly to the outfeed table if not sure have a read of the instructions on how to set up correctly

 

Hope this will be a start

a picture speaks a thousand words....

 

Wood is touching at either end but theres is a gap in the middle.

 

Seems to bend the wood on when passing through the thicknesser, worse on small pieces like the ones shown above.

Planer is an awd' Luna 40. I can not find any documentation on the machine. The machine itself has had a full set of new belts and would be perfect if I could just sort the planer side of things.

 

Hope this helps....

 

Hi Drew,

Have a read of this post

no matter what the manufacturer says be prepared to experiment to get the best compromise.

Ah (no manual) so you don't know what is recommended, try what is in the above post.

 

Let us know how you get on.

That would more likely be the outfeed table is set wrong,

 

As the timber comes off the blades if the table drops off the timber will ark, check and adjust the table is parralel with the infeed table, parralel but obveously the thickness of the cut lower

also,you could try putting a suport under the wood before it gets to the infeed table,if it hasn`t got cast iron tables you can get warping of the tables themselves and extra suport either end for the wood can eliminate the problem you have,regards,

Hi Drew, as Bill has directed you to my post I had a variety of similar problems with my machine and setting the blades to the same height as the out feed table solved just about all of them.

One other thing to check is make sure your blades are nice and sharp.

Hi Drew, As has been previously said you need to ensure that when the planer is set to zero both the infeed and outfeed table are perfectly aligned. Do this with a straight edge, they also need to be perfectly flat (no warping). If there is a slight difference then you will need to pad out the misaligned unit. Once this has been done make sure that the blades are set level with the outfeed table. When you are planning don't put too much pressure on the infeed table, keep the pressure on the out feed table while pushing the work through from the infeed end. Hope this helps -- Julian

thanks all for your postings... think we could be on to a winner here, I have just been out to the workshop & put a straight edge from the outfeed table to the blade and it's set a lot higher!!!

 

Will let you know how I get on once thier reset.

 

 

Blades have now been set level with the out feed table and problem has been cured, however when using the thicknesser (underside of the table) the issues still persist....

 

 

You are not getting a bit of snipe on the ends are you Drew ? You generally need to alow a few inches on each end of the piece for where the wood leaves the machine, the middle bit being on a flat bed can't be anything but flat and parallel
