Hi Everyone.. I was reading the Timber Wolf web site recently and it said that you should always “Detention” your blade at the end of every work day. It goes on to explain the reasons for this and they make perfect sense. Somewhere along the line I missed this and I have never detentioned my blade. I am just curious as to how many of you do this.

I know I’m supposed to but….

I usually forget.

I’ve seen somewhere, a quick tensioner/detensioner lever that looks like a good solution.

On my big bandsaw, I have a lever that releases the tension easily, so it just takes a second, on the smaller
shopsmith, I have to use the standard hex key to release tension, so I drilled a hole in the side of the cover
and made a small window in it to see the tension bar to make it easier to do and remember. I believe the
newer shopsmiths have added these features. I detension the blades after each usage, before I shove the
saws out of the road to put my pickup in the shop for the night.

I do it every time but it is a PITA because I do not have a quick release lever.

I only do it because all the books I read on the bandsaw told me to.

Thanks for the responses. I guess I had better start detensioning my saw blade.

Always. I have a quick release lever on my 17” Grizz which makes it easy. The hard part is remembering to tighten it before I turn the saw on! Don’t ask.

Always; and, usually right after I finish with it.

When I remember to I do it, usually I forget… i’m not sure how much it effects the blade, but I haven’t noticed any issues yet.

I didn’t de-tension for a long time…and a piece ended up breaking on my Jet bandsaw, when I started woodworking again. I was fortunate that they still had spare parts for my older saw and I have faithfully taken better care of it this time around. Bandsaws are not as cheap as they were 25 years ago! It’s just something I’ve made myself remember to do.

I learned mine the hard way. I started de-tensioning only after I have broken a blade by not doing it. I read from different forum sites and this band saw blog site about this but just ignored it. Now, I never leave the work area without de-tension!
