I use a small Delta every day to cut brass, german silver and steel. It ran too fast when I started this job, I thought. What I did was slow it down. I took a piece of al. I bored a hole . Next I made a shaft with a step pulley on it and pressed the shaft into the bored hole. At the other end of the al I put another bored hole with an old bearing in it with another shaft. I milled a flat on the end sticking out and drilled a couple of holes at this end and mounted to the frame of machine. got a coupple belts and I had slowed down the thing by about 50%. This was just a guess as to the right speed by me but the amount of blades the company used on this machine went down from about $1000/yr to 200/yr. The cost was two v belts, old bearing, two bolts and some al that was laying around. When were doing steel and I don't do much on this i,m only cutting .060 thick at the max. I was planning on doing something similar with two of my step pulley al. pieces to slow down another bandsaw for doing greater dia steel but never hae time but its the same principle
