The big major difference is blade speed. You will want to run a wood saw in the 4000FPM ( feet per min) range and slower for metal, as well as using a blade designed for metal. I dont recall the blade speed but it should be available froma metal bandsaw blade manufacturer. The bandsaw you have can be converted to cutting wood by changing pullley sizes to obtain the desired speed of the blade

What type of bandsaw is it? True metal cutting bandsaws have a weight mech on them to constantly keep pressure on the cutting surface, cutting cold rolled steal take about an hour an inch. Do you have any specs on the machine?

It is a Dayton 6Y942B blade speed 80 150and 200 FPM 1 hp motor 1725 rpm what other spec. are you looking for I was told by granger who makes the saw that indeed it is metal cutting only now whT I am trying to find out is if I can convert it by changing the pullys and I think I have to do something with the guides as well, I am having no luck on a couple of differant blogs in getting the info I need to make it a wood cutting saw. I am thinking of trying to sell it and just buy a wood cutting one.

So Iguess I would have to take the gear box off and find out how to mount a pully on the shaft for the lower wheel of the bandsaw

Jim,

According to the Grainger Catalog ( http://www.grainger.com/Grainger/items/6Y942 ) this BS will cut wood also, in fact they ship it with one wood cutting blade as well as the metal one.
You just need to set the speed too the highest setting of 3000 rpm choose a suitable cutting blade and you should be set.
By the way in case you have doubts how to select the highest speed, you choose the smallest diameter size on the motor pulley and the biggest diameter size on the driven pulley. From your photos it looks like you will need a bigger belt for that.
Have fun….

Jerry that is the newest bandsaw they make and it does cut wood and metal that saw although it doesent show on the web site has a E or D at the end of the # mine has a B and it defently only cuts metal the top speed is 200 FPM. I do wish it was that easy though

I would hesitate to spend time and money on this bandsaw. It will never be as versatile as a woodworking bandsaw. For example, on my bandsaw I can select blades from 1/8” to 5/8” wide. I have a fence that can be adjusted for blade drift, and I can resaw boards virtually to any width. The table can be tilted for bevel cuts and I can vary my cutting speed.

I called grainger and the place witch makes the bandsaw and it does not go higher then 200

8iowa it is as versatile as a woodworking saw . It was free and it takes blades from 3/16 to 1” it has a fence that does the same and the table tilts as well and with the right pulley I should be able to do the same. That is why I am trying to convert the saw new is about 2000.00 so even if I have to put a couple hundred into it it would be well worth it , If it is posably. I am trying to sell but I dont think I will be able to get enough to replace with a new 18” bandsaw. so I am really trying to figur it out

I wish I was where we could get together. I love this sort of project and while I sorta agree with 8iowa, I also disagree (but with some hesitance).

What makes a (woodworking) bandsaw into a (metal working) bandsaw. I think speed and the type of band and the ability of the machine to operate SAFELY at those speeds while accommodating the appropriate blade.

There is no doubt that I (you) can make those wheels turn as fast as you want them to but will it be safe.

As far as changing blades – that seems to me to be a no brainer (if you can find wood working blades of the appropriate length. Once you change the blade, will it track properly. What sort of tracking system does this band saw use and why might it not be appropriate to use at ‘higher’ speeds?

Sorry – there are no real answers to your questions. Just belief that you can make this happen if you want to but BE SAFE. The $2000 is not worth the cost of an accident while you are pushing the boundries of the machine.

Jim, I agree about safety, OTOH, you can use it as a wood cutting bandsaw now. Even if the blade is moving at 2000 fpm, the only thing that really matters is how fast you feed it. My thinking, though I could have it backwards from Jerry, set it on the biggest pulley on the motor, and smallest on the driven pulley nearest the bandsaw wheel and put on a good blade and feed slowly and see what you get. This calculator shows the rpm based on various sized pulleys http://www.csgnetwork.com/pulleybeltcalc.html, this one shows how to convert rpm into fpm http://i-logic.com/utilities/sfm.asp You will also need to figure out what the gearbox is doing to make a true calculation. Again, I wouldn’t get too concern, spm is an optimal – it will work fine at a slower speed so long as you reduce the feed rate.

dusty I wish you were close as well. I am not really cuncerned about safty with this bandsaw dayton also makes a wood/metal cutting saw that is basicly all the same except the wood one has a clutch that you pull a lever and it disingages the gear, S as long as I could come up with a way to get rid of the gear I will be good. The blade is the same length as other 18’ wood bandsaw blades. Barry It will not cut wood very well if even at al at the speed of 200 sfpm (not 2000)
