I have seen it done a few times. You have to find a way to slow the blade speed; normally an intermediate shaft is added. Have you googled the conversion?

All i do is change the blades on mine for wood or metal. I even freeze deer quarters and saw them up. A little messy with the meat cutting, but it all cleans up

Popular Machinist & Home Shop Machinist forums have many threads on the topic. Most rig up an extra pulley & jack shaft but I remember one fellow put the biggest possible pulley on the saw and the smallest possible one on the motor and claimed it worked OK.

I converted one over by using a right angle gear reducer. I don't have it anymore or I would get you some pics of it.

I have a 10" delta band saw that I converted using a 100 rpm, 1/4 hp gearmotor that I got at a surplus house in about 1970. On this band saw, the 1725 rpm motor that drives the saw fo woodcutting is mounted on the bottom shelf of the saw's stand and has a pulley that's about 2 or 3 inches iin diameter. To get the saw blade speed down to about 100 sfm for steel, I put a pulley of about 1 1/2" in diameter on the gearmotor's shaft. The pulley on the saw's lower drive wheel is about 6" in diameter. I mounted the gearmotor on a second shelf of the stand that I made so I could pivot it to add a belt tighteneing feature.
To cut wood, I install the nomal belt between the saw's lowe drive wheel and the 1725 rpm motor.
To cut steel, I remove that belt and replace it with a shorter belt that runs from the gearmotor to the lower dirve wheel.
The on/off switch for the saw is mounted on the top shelf, upon which the saw itself sits. I rewired the machine so the switch output wires terminate in a receptacle. Each motor has a short power cord that can plug into that switch receptacle. That way, when I switch belts to change from wood to steel and vice-versa, I also switch motor power. In this way, the same switch is always used to turn the machine motor on and off.

I have often used metal cutting blades to cut wood, but recently started buying coarse wood cutting blades and I find that it's well worth the time to change in most cases.
Obviously, I hope, one would be smart enough to NEVER use a wood cutting blade on steel.

I changed my Delta over with a DC vari drive and controller, now it can cut anything wood, plastic, steel, copper, etc. Have to keep a variety of different blades, as to be expected.

I used a gear reducer and a set of chain sprockets to get from 60 fpm to about 600 the pulley belt thing eats up alot of power about 50% eff. compared to chain being up wards of 90%
I sawed up a deer but the blade smelled horrible when sawing metal latter on kinda rancid smell

hi john,
thanks, i also have a vari drive that i've tried but it seems to have a not so desirable effect on power when you slow the rpm down. maybe the drive is not right for this app. thanks again, gene
