Q.
I am interested in purchasing a saw to mill mahogany and teak.
Which type of portable mill will be best for making large boards for shipment and resawing later at a stationary mill? Which mill is most durable and maintenance free? Which mill will easily produce 3000 to 5000 bf of lumber daily?

You could make larger cants with a band mill, but it would be easier to pack a swinger into the bush to cut the log where it lies. The swinger can handle a much larger log than the band mill, but recovery is better with a band mill (less sawdust). My choices would be a Wood-Mizer LT40hd for the band mill, as that is very easy to set up anywhere and not as finicky about leveling. For a swinger, I’d pick the Peterson. Much simpler mill than the Wood-Mizer, less to go wrong, sets up easy, cuts strait, sharpens quick, cuts smaller boards fast. Making 5000 bdft everyday will be a tall order with either of these mills. You will need support equipment (tractor, skid steer) and some grunts (strong backs) to help you. Can be done, though.
Those are very dense, heavy woods, so I would suggest either a very large swing or a Timber Harvester 36 HTE 25 or with the 40 horse diesel. You can be a lot harder on a TH than a WM without throwing it out of whack. I have had a couple WM owners watch me run mine, and I do things they wouldn't think of. 15-20 times a day, I slam the head into the stoppers on the end of the track. I do it accidentally, but it doesn't effect my adjustment. I check it once a month, if I remember, but have only adjusted 5-6 times in 2400 hours. Don't settle on a WM just because they have better fliers and trained salesmen. You might be better with a carbide tipped band, but if you go that route, you will definitely want larger than 19" band wheels. The larger TH have 25" wheels. That will extend your blade life. Most importantly, have fun and be safe.
If you go with a band saw, try a 1-1/2" cobalt band from Suffolk. With that dense wood, you will need a good band. That is another advantage the swinger would have.
I look forward to doing some of the operations myself, but I agree that I must employ experienced sawyers. At minimum, I need some serious training and my help will need the same training. Literature, research and comments have me believing I might be on the right track. Now I need to see these mills in action and find good used ones. Today, I am scheduled to view two operating Wood-Mizers.
After some experience with that, you will know much better what you need to add to your operation.
They cut teak, rosewood, and Sitka spruce for guitars. In the down time, they cut other types of wood. They even cut white oak in thin slices, and put back in log form with stickers in between the layers. Those went to the export market.
They used a conventional band mill.
Stickering and putting back into log form is something I haven't seen for a very long time, except in books. I understand it is still done particularly for musical instrument woods. I would be interested to know why, other than tradition.
