I have spent years building a proper wood shop. With the addition of that big cabinet saw and a jointer recently I am in heaven. I will give you an example. That big humi. I rip and cut the ply to size on the table saw. I cut the box angles on the table. Make the rabbit cuts for the base on the router table I built into the table saw. Now for the liner, I have a ¾”x8”x3’ Spanish seeder board that needs to line that big box. So I rip it to two 4” planks, plane them to make sure they are square then resaw them into 4 3/16 inch boards from each section, then plain out the mill marks and make sure each is the exact thickness. Now that one board has become 8 4”tall, 3’ long boards. You cannot do that in a table saw and ripping a 4’x4’ board in a band saw, while possible, would be a major pain and your results would probably suck. But we are getting way OT.
To cut the rolling angles used in scales, you need a thin blade, be it band saw, scroll saw or coping saw. You can put a ½ inch blade on a band saw and resaw ebony, maple, bone, horn, antler, composite, etc… I have cut them all in my saw, and for just scale making a good band saw, 6 or 8 inch table belt sander and a spindle sander will do wonders. I have made a dozen sets of scales in one afternoon but I have it down to a science at this point. A word of wisdom, don’t go cheep. Yes you can get a band saw for $200 at the big box hardware store, but you will be disappointed. You cant do a big job with a small tool, but you can do a small job with a big tool.
