I recently bought a used 14" Delta BS. I am happy with it but I have no experience with this type of saw. I currently have a 0.25" blade installed. How tight of a radius can I expect to cut with this blade. I used it to cut a 1.0" radius. It worked well but I did some back and forth moves that left some ridges to sand out. I'm no sure how far I can deflect the blade trying to force it into the desired arc.
I've seen a demo video on youtube where someone cuts a three dimensional reindeer. He was really deflecting the blade to make some small curves. Is this normal or was that overdoing it?
1'8" 14 tpi=3/8"D.
A 1/4" blade will cut 1/2" radius or 1" diameter.
1/2" 3tpi=2.1/2" D.
3/4" =5.1/2" D.
All this info came directly from Mark Duginske's "THE NEW & COMPLETE GUIDE TO THE BANDSAW" book.
I use the same chart that Ken cited. (that is a great reference for all things bandsaw)
The reindeer you saw were cut with a Carter Stabilizer which allows you to twist the blade further than conventional guides. It also allows you to back out of cuts with the saw running without pulling the blade off the wheels.
Another important point is that after cutting any wood with a band saw the cut surface will need to be sanded. How much sanding do you want to do? A scroll saw, on the other hand, will cut a radius as small as 1/8" radius or less and will require no sanding. The cut surface will be that good.
At one of the WoodWorking shows I watched a guy at the Carter booth cut many three dimensional reindeer as he was displaying the ability of a very thin blade to cut very, very tight radii using one of their stabilizers. Those reindeer must just about be trademarked by Carter as I've seen the same thing in many videos as well.
