Looking for advice about resawing beams

[Nomad]

     I've got a job coming up to resaw a bunch of SYP beams.  Old, old beams!  True 4x8 beams from a demo'd old building.  I've resawn old beams, but never old heart pine like this.  Any recommendations on blades?  How about lube? 
     These old timbers are just beautiful and I really don't want to mess this wood up.  Any advice is welcome.

Nomad I use tide for cold water as a lube with water. Its the only thing that I have found that works, about 1 cap full to 5 gal. 1 1/2 " 7deg .045 bands work great.

I've done a lot of that on old heart pine (SYP) beams. I used 0.042" Simonds bands, 0.025" set, diesel wipe top and bottom of band. Expect nails.

I resawed a SYP beam. Once. It was definitely pitchy. I used a WM DoubleHard .055"x10° It sawed well, even after I hit 7 1/2" lag bolts. Well, it was sawing about a 1/2" higher than it was supposed to at that point. :D I found that resawing big beams left a lot of checks in the boards.

We got some beautiful material from it.

Take plenty of blades with you. Even if you don't hit any metal the dust that is deep in the grain of the wood will take the sharp off pretty quick.

Pitch will be a real problem.  You will occasionally have to run the blade with the lube open to clear it off.

This will be interesting.   ;D

I'd say saw them, it should be good.    david

Keep the lube on and bring plenty of sharp blades and most of all scan all beams before sawing with a metal detector!The stuff is hard and gummy,I keep the build up off the band with ATF and a wire wheel attached to a 6" bolt and squirt with ATF and hold the wheel against the turning band. Tim

If you use soap and water, bring some diesel as back up lube and use a good drip of it. Those beams can by very sappy. I only use diesel on those, also I use a wiper like cooks sell instead of drip.

     Well, sawed those beams today.  Turned out to not be all that big a deal, but I think in part that's due to Gasawyer's suggestion to try Cold Water Tide.  There was a lot of pitch, and that stuff worked great!
     I only hit hardware twice.  Sliced both of 'em lengthwise.  Go figure. :
