   GOI,
   If you are sawing a stack of 21/4 slabs on your bandmill,then rotating 90 degrees,that's probably the fasrest method without major equipment changes. Your next best option might be an edger with several fixed blades.This will work,and work well,problem is time,and handeling. You still have to cut your flitches,move them to a staging area by the edger ,then feed them through. Even with additional manpower,the time and effort involved is the same.If your flitches are wider than the setup on the edger,then they have to be returned,more time ,and handeling.
   It could be done,probably quite well with a coupla turnarounds,your 21/4 cuts going one way,and the flitch returning another,that way ,you could have several in motion at one time.Still it will take some mechanicals, and labor. Don't know what kind of volume,or how long you plan to do this. Would it justify the investment ,and effort.
   Depending on how your bandmill is set up ,a rack on the back side to push the strips into once the second cut was made seems like the fastest way to me,but I'm probably missing something important.

Brad

Most edgers have a set blade and an adjustable fence that should give you 1/2" increments.  That's how we do 2x2 for stakes.

It is looking like this will be a long term project and worth the investment. I just dont want to get carried away and go into debt to get started and then work the rest of my days trying to pay for the investment.

I have produced a bunch of these with the Peterson ATS sawmill, but tailing the boards and having some way to automate the log feed to the mill slows me down considerably.

Loading logs and turning them after being cut into slabs is a slow process on the bandmill also, especially turning the logs.

I am looking for solutions to increase the production rates so that I can make some money at this. It seems to me like cutting the logs into slabs and then feeding the slabs into a gang saw while cutting another slab with the bandmill would be the best way to produce a large amount of these in a hurry.

I'm a lumberjack and I'm ok, I work all night and sleep all day

If you have no way of moving the slabs other than the Armstrong method, you won't get much more done.  Wouldn't a double cut or a dimension mill be a better solution than a big gang saw?

It seems to me that a dimension mill would be able to cut one on each pass, for the most part.  Feed rates are better than the band mill and while the mill is cutting one, you are stacking a cut one.

I looked at my mill this morning with that question in mind.There are normally two 4" horizontal edgers on the dimension mills with a third edger blade that can be added in about 15 minutes.If set up this way,a person could saw out three 2 1/2" squares in every pass.(or three 2x4" or 4x4 etc  )

Since this has been brought back from the dead. What would a twin saw like a mobile dimension followed by a sash gang look like. Use the big edger blade and the drag back would do most of the moving. Push it straight into the sash and mill up the next can't while that one is going through

I think it'd look pretty silly..I dont think Mobile Dimensions are really cut out for cutting big cants and dragging them back but thats just

Like Doug says the dragback is going to be your weak link. You need a variable height belt offbear so that as soon as the flitch is off the log the belt is taking load off the dragback... and y'know its just easier to feed the same resaw with a carriage headrig.

I've looked for years at that kinda combination and I can definitely see the potential there if you had the right logs for it (because lets face it  - thats a big log system if ever there was). I'd suggest that rather than a MD you need to be looking at a Duncan Beam Saw though... MD's bigger uglier brother with a steroid abuse issue . You start playing with big flitches all day and believe me you're going to want it built heavy so things dont break. The biggest of the Turbosaws is another one that offers potential but same issue... you got a ½ ton mill dragging around ¼ton flitches all day and it wont hold together for long.

Yanno I hate the idea of band headrigs but if you dont want a conventional carriage type headrig for primary breakdown - say if you wanted to be more transportable - one of those Sanborn slant rigs might fix the problem.
The quickest way to make a million dollars with a sawmill is to start with two million.
