Thread: What size Bandsaw Blade?

  1. What size Bandsaw Blade?

    I have a Delta 14 band saw with an extender. The distance between the two wheels is 31".

    My old blade bent and I threw it away, thinking I had some replacements, but they are all too short.

    So... I need some recommendations for where to buy a couple new blades, and how to figure out what size to buy? I guess I could just run the tape around and measure, but I figure you guys probably already know this answer...

    Thanks for the help

  2. ok... I think I figured it out... pi*D ( half a circumference on top, half on bottom) plus 2 of the 31's, one for each side...

    so 3.14*14=43.974 ... so make it 44 plus 62 = 106

    That sound about right?

    ok... so much for being lazy... sorry to bother you... Guess I will do some readin...

    I dealt with this with an old bandsaw and it was a bit of trial and error. Then you can bet I wrote that down many places! Do you have a model number anywhere? I believe most of the Delta's are essentially the same design for years, but I would imagine there is some variability and the riser makes it interesting. Sorry, not much help here, but I would see if you can find the exact model number and search from there.

    A chart like this doesn't really help when you consider your riser block!

    Depending on how old your saw is, this seems like a place to start:

    Generally, the Delta 14" cast saws and its clones with a riser block use a 105" blade so you are in the ballpark but I might get a 105" blade so you don't tun out of tension ability.

    Your blade will be 105" I have the same saw. I do a lot of resawing with mine. I use blade from highland hardware . The woodslicer is for resawing if you are doing that. Also do you do blade drift ?? If you don't what that is post back and i will explain good luck

  6. thanks for the help.

    Dan, it is a Rockwell Model 14 and not Delta. The serial plate has 25-203.

    Van, I really like your "Lets talk bandsaw" thread... it is great. I looked at my saw and the tensioner looks to have lots of room, as in several inches to get smaller.

    Del, I haven't used the saw much, although I have had it for quite a while. What is blade drift? as in for resawing? as in the thickness of the cut gets bigger or smaller? I haven't really tried any resawing... although I really want to
