For curvy cuts on a BS, I usually use a small BS (Shopsmith) and I use my 18” Jet for resawing and other straight cuts. I had a situation where I needed to cut a curve on a piece of oak that was 6” thick and, for the first time, I put a 1/4” blade on my 18” BS to cut a curve with it.
Some of you saw my topic yesterday when I indicated that I was getting sparks and some of you said I was probably trying too tight of a curve (The radius was 3.5”).
This raises the question in my mind – - How tight of a curve should you be able to cut with a BS under different conditions?
Obviously, this differs by the size of blade. It probably also differs by the quality of the blade (I use Timber Wolfe) Does it also differ due to the hardness or thickness of the wood? Does the grain orientation affect this?
In my opinion, a 3.5” radius should be able to be cut with a 1/4” blade on a piece of oak that is 6” thick. I could do it, but I was generating sparks and it felt like I was at the limit of what I should do. It’s also my opinion that grain orientation does not matter.
On another cut, I did a curve with a 4.5” radius and that was not a problem.
I welcome any advice based on your experiences with cutting curves in thick pieces of wood with a BS.
