Topic tags/keywords: resawing resaw band saw bandsaw tension tpi hook tooth deflect craftsman 113243311

I just picked up a used ½hp, 12” Craftsman 113.243311 Band Saw for $100 so that I can finally do some re-sawing. I followed a Fine Woodworking article (#0189, Jan/Feb 2007, p.89) on how to setup your machine for best results. It guided me through creating the vertical fence and gave me some suggestions on belt tension.

I am completely new to the band saw. My blade delflects quite a bit when I press my finger into it, even when I have the tension dial set correctly for the blade’s width. It flexes TOO MUCH in fact (more than 1/4” as the FWW article points out). Even after taking the tension dial all the won’t let me go any further, it still deflects too much…

I’m not sure if the blade it’s using is an original. The machine’s owner’s manual calls for an 80” blade/sanding belt (it’s both a sander and a band saw). It currently uses a 6TPI 3/8” blade.

I’m looking to get a ½” 3tpi hook tooth blade (per the FWW article) but I want to know if it’s practical to have it made at 79” (rather than the 80”) just to increase tension.

Thanks, jocks!

I would grab a piece of string and install it on the machine instead of a blade, with the tensioner set around, or slightly below, the setting for the 3/8” blade, and see how long the distance actually is. If the blade came with it, and doesn’t tension properly, I wouldn’t trust that the previous owner purchased the right blade. You could also use the string to measure the length of the current blade. Having a machine’s manual state it needs an 80” blade, and then not be able to bring it to proper tension, sounds odd. Some blades, like my Timberwolf blades, come with tensioning instructions that put them just slightly more snug than fluttering. I don’t use the settings marked on my Delta’s tensioning system.

Before you try a shorter blade, try this method of tensioning.

In case you didn’t get the manual, here it is.

I own the same saw. Sounds like you need a new tension spring they are no longer available from sears
You might be able to get one at a hardware store
4” long 3/4” od 15/32” id 5/32” wire diameter

Thank you all for your informative replies. I have a list of things that I will be evaluating this evening after I get off work. I’m hoping it’s simply the spring and that Hartville Hardware (closeby) has one I can pick up. Thank you for providing those dimensions!

I recently replaced the blade on my 10” craftsman with
a 1406PC Timberwolf band saw blade from Suffolk.

It works so much better than the stock blade I recommend all stock blades be replaced!
The string idea sounds good, how much adjustment do you have on the tension?

@Deputy4989: I’ve looked and looked online. Even ereplacementparts.com does not carry the part. I will be making a trip to the hardware store to try and find one that compares. It sounded like you’ve been through this, where did you find your replacement?

@Farrout: I’m not really all that sure. My band saw nomenclature is virtually non-existent at this point. I plan to do some reading today to better understand how to measure the actual tension, etc. I’ll report back to everyone what I make out. Perhaps once I arm you all with accurate specifics to my situation, the culprit will be more apparent…

There should be a knob at the top of the saw that controls up down adjustment of the upper wheel.
You will need to lower the wheel to replace the blade then raise it back up to set tension.

@Deputy: I saw the one on ebay but refrained from purchase due to it being used. I could be buying one that is just as inoperable as the one I have now. I would much prefer to buy new and would only buy used as a last resort, BUT.. thank you all the same!

@Farrout: Yes, I am familiar with that. Once I remove the enclosure, there are embossed settings with an extension arm (dial), much like a clock face and hands. I have tried setting it to 3/8” blade, deflection remained. I also wound that knob all the way down (max tension) and I still have deflection (less but still too much).

I just wan’t sure how to answer your question about “How much adjustment I have on the tension”. I didn’t know if you were looking for some type of technical answer is all.

Sounds like your problem is with the blade. I suggest either a woodslicer 3 TPI or a Carbide blade 3 TPI. (what I use) Measure with the sting and get the right length blade.
