I had someone contact me about covering a 9x12 wall with walnut.  It made me think about resawing 4/4 down to whatever it would be to double the use of the boards.  Of course she would have to pay me for doing the work of resawing.  I would probably need to invent something to allow the operation without sawing into side stops.  I'm also concerned about the wood cupping badly.  Anybody do this?

We resaw all the time with a dedicated horizontal resaw using Laguna Resaw King carbide tipped bands.  It works well and the band kerf is only .035.  The Resaw Kings - once resharpened and reset by Laguna - are the best that I've ever used.  Kerf marks are almost indistinguishable (.010 or less).

Typically we're starting with 5/4 thick stock though.  After drying we will skip plane it to around 1-1/16", then straight line rip and rip to width.  We then run it through the resaw to procude 1/2" thick boards.

Your biggest challenge is to be sure that the lumber has a very consistent MC% from core to shell.  If it's off by 1% or more the boards will cup or bow coming off of the resaw.  Also, using a normal band mill is not very precise and the kerr is thick.  You're probably going to net out around 3/8".

Thanks for the info.  I'm definitely concerned about cupping and the kerf.  I have a 17" bandsaw, but I'd be hard pressed to run 8" boards thru it.  She wants the boards to be roughsawn, so the mill would be fine as far as that goes.  I think I'm just gonna not offer that option.

You may be wise.  Sometimes what they want is not what they wanted when they get it.  I would prefer to decline rather than to risk having a dissatisfied customer.

You're probably right.  She wants to cover a large wall in rough sawn walnut.  I told her $750 would about do it.  It was my idea to resaw, but I never mentioned it to her.  I can't think of a worse way to use this beautiful walnut anyway.

Rough sawn sounds "romantic" but the fact is rough sawn collects dust, lint, and whatever else and is very difficult if not impossible to clean.

Oddly, hewn timbers are slicker and are not as difficult to keep clean.


 
A brush on the vacuum takes care of them.

We get lots of request for rough sawn and resawn roughsawn. Then they want it to be cheaper because it hasn't been planed, until I tell them it has to have at least one flat side, so it's got to at least go through a planer once.  
Typically, most people are pleased with a lightly sanded roughsawn or a "burnished" rough sawn that has some of the sharp edges taken off.

Sometimes I just point the customers to stack of roughsawn kiln dried and they take one look and make some comment that they thought it would look better than that. ::)

Hand hewn is a whole different animal, as Magic says, I even bought a good broadaxe and hand hew occasional beams and mantels when I'm bored.  Then I leave them in the sun and rain for a bit in the customer's eyeshot (I stack them by the Porta Potti) and before long they are sold.  
YellowHammerisms:

Take steps to save steps.

If it won't roll, its not a log; it's still a tree.  Sawmills cut logs, not trees.

Kiln drying wood: When the cookies are burned, they're burned, and you can't fix them.

Sawing is fun for the first couple million boards.

Flap sanded rough sawn looks very nice.


 
But then it isn't "rough sawn".  ;D
