Problem with Jet thicknesser

[mpooley]

Hi all
My Jet thicknesser is getting very juddery when I adjust the thickness !
only on one side I think.

Is there anything I should look at first?
has anyone had/overcome this problem before?
I'm not a mechanic so any advice at all would be appreciated.

thanks

Mike

Mike, do you mean it's NOT juddery with a fine cut but becomes juddery with a heavy cut?

Do you mean when you wind up the handle?

If so it probably just need cleaning.

Has it ever been cleaned and lubricated?
Machines don't run forever without care and attention.

Mike,

I used to have a JPM13 and had a similar problem, basically when you would the height adjusting handle on the top one side would raise by a small amount and then would not go any further and the handle was very stiff.

Basically what had happened was the chain drive sprocket under the machine which links the two threaded rods had come loose and the allen key grub screw needed tightening. Make sure when you do tighten it though that the blades are parallel to the table otherwise your boards wont get thicknessed evenly across the boards.

Once I tightened mine it was perfect again
