Some 150 years ago these Heart Pine beams were milled, and in the spirit of recycling they will now be reclaimed and repurposed. The rings were tight and the pitch was heavy but almost 100% clear. Rolled the mill right into the warehouse where a dozen workers with metal detectors, pry-bars, chisels, hammers, etc. removed the decades of hardware and debris.

The beams will be further machined and eventually used to build a lodge-sized timberframe home.
I have spent almost three days at it and there's a lot left to do.
I had a job simular to that a few years ago, swaed some river booms to be made into a post and beam house, did a whack and a half .... Had a few helping out, one on the metal detector, two on hammer and pry bar.
Nice lookin' wood
Gorgeous! :)
Hope there's not much hardware in there.
You must have nerves of steel to back the mill in like that! :o
I also had similar jobs but your guys were more successful at finding nails. Did you hit any? What blade lube did you use?
Bob
That looks mighty nice!!! That would look awesome in a home that used a country-outdoor-logging theme.

They where real good at getting the nails... detector did not fing the grit or stones and we did saw the odd metal incrusted peice, :-\
as per lube, I mostly use windshield washer, it has detergent and wont freeze. I will once in a while use water and dish soap!!!
In the 60-80 beams that made it onto the mill so far, I hit metal 6 times. The metal detectors do a good job but I think there was some operator error. Still not bad considering they had filled two 55 gallon drums with metal that had been removed. :o
I use water and Cascade, but keep a squirt bottle of diesel at hand. This stuff required me to address the blade after almost every cut. Think i will try a diesel drip next time.
I'm noticing that many times (on other occasions as well) metal doesn't always destroy the blade...
I seems to bond some onto the edge of the tooth and I'm sure throw off the set, but as long as it isn't a lag bolt(or backstop)::) ....
the teeth dont always bust off!
I use the Resharp service and wonder what they think when I send a dozen like that ???
I have found that hitting a nail at 90° angle the band will still cut straight but hit it at an oblique angle the band turns into an airplane wing, rising or diving (usually rising for me). A lag bolt and the band is toast.

The last picture is that nails you have sawed through?
I found working on old timbers for timber frame restoration that just because you pull the nail, doesn't mean there isn't a bunch of rust in the bottom of the hole waiting to ruin the band. I once hit a 1/2" lag in an old SYP beam I was resawing. I hit another with the new band, so I figured I would finish the cut and find the rest of them. I cut off a total of 7 1/2" lags with one band. :o It was cutting about an inch high when I got done. :D

No, those had been pulled by the de-nailing crew.
On one beam I hit a 1" piece of solid round stock steel, they dug it out while I changed the band. 4 feet further down(with a brand new band) I hit a bolt. Niether were visible to the naked eye.
I charge $25 each time I hit metal, whether it shears the teeth off or not. Sometimes I feel guilty about that.
Is that pretty standard practice among the rest of you?
I charge the cost of the band. If you are hourly, then you are still on the clock when changing it. If by the board foot, then I suppose you could add on a little bit to the cost of the band for the production lost while you are changing the band, but it wouldn't be much. Now, if you are loosing time waiting for a denailing procedure and you are by the board foot, then that would require a special agreement between you and the customer.

It is standard practice with me and I do not feel guilty.

I charge what ever it is the last blades cost me. Last time I sawed metal it was my own. ::) I had put screws to hold a tarp over my mill and was sure I had them all, famous last words.
