Chipper Wood chipper knife clearance ?

[GrayBeard]

I've got a general question about knife clearance relative to unit performance.
I might add , it makes no difference to me what the chip size result is.
I've got a BX 40 Wallenstein with 3 rotary knives (540 rpm) and 1 stationary.
My question is as stated before , what is the optimum distance between the rotary and stationary knife ?
The chipper doesn't do badly now (1/8" clearance) but I don't know what the "rule" is.
I didn't get a manual and Wallenstein's customer support or lack of is another BIG post.
Thanks, GrayBeard

Can I see pictures of that unit? I have not seen a unit with a rotary and a stationary knife. If I saw, I'd make some comments. Can take a picture or give a link to a web page showing them?

nomad,
I can email you one if your add. is listed. It may be a day or so.
My re-sizing abilities are not good for posting here.
The stationary knife is located at the bottom (side) of the "drum" and the rotary blades on the flywheel just pass by.

Most chippers have rotary and one or more stationary knives (anvil, bed knife etc.) As for the bed knife clearence, .070 is pretty comon. Hope that helps.

Graybeard;
I agree with Chipperman. I have a Vermeer 620 chipper and the knife clearance is .080. So .070 sounds about right.
Good luck.

do a search for a program called EasyThumb on Yahoo or Google. It is a program that will take all pictures in a folder and change them to any size you want rather easily. Be carefull though if you don't select a different folder it will write over your originals.
