Sharpened bands wander all over?

Hi,

Local Hdwr store is a drop off for a sharpening service that used to do ok on my bands but recently they cut ok but track all over.   I had some bands sharpened by another operation and they go good.  I plan to discuss this with the HDWR service, but want to make sure I give them feedback they can use.  My sense it they either do not set the teeth or do it before they sharpen.  What other advice can I give them?

I happen to have an old hand setter.  Can I set the teeth on these bands?

Thanks.

Sure you can set the teeth. I believe most here that sharpen set before sharpening. It was the way I was told to do it, and, it works well.
All truth passes through three stages:
   First, it is ridiculed;
   Second, it is violently opposed; and
   Third, it is accepted as self-evident.

Your example is the reason that I quit using a local sharpener and use WM ReSharp.  The sharpening cost is the same, but the quality is very different.

What do they charge to sharpen a blade?

Who are you asking?  WM is $10 which includes shipping both ways.

Just as a wild guess I would say they don't set. I get 2-3 sharpenings between setting. That could be the reason they used to do OK. The set just wore off.

Not enough set or set more on one side than the other could cause wandering.

I agree with Brian!

More set on one side than the other.

$8 a band for the hdwr store and  I suspect they don't set.   The other guy gets $9 a band but apparently does set.   I can just go to the other guy but if I can constructively criticize the local dude and have him improve his service we all benefit.   If he tells me to stick it ill just use the other guy. 
Last I knew,   Woodmizer only sharpened their own bands.

I think if he should have checked your set before he sharpened them.If he has no setter you need to find someone else.

you can look down the band and see if its set anywhere near correct at a glance. the teeth should be fairly close to half a tooth out each way, typically it is the cant side of the band that loses set first for me.

if i notice the band needs set i will set before sharpening, but i also get a few sharpenings before they need set again.

if i have a sharp band with less set that will not cut pine, it will cut good in oak... just another small tidbit i have no ;Dticed.

We cut a lot of cottonwood. Sometimes we have to up the set right out of the box. Depending on how fuzzy the cottonwood is. Lack of set will make the blade go crazy. Poor set will as well, as in one side set way higher than the other. You could probably make your own dial indicator by getting a cheap dial indicator from harbor freight, and fashion a bracket, and determine what your set is. My guess is Cooks, Timberking, suffolk machinery, already have them set up.

I sawed  my house out of white pine blowdown five years ago but haven't done much with the mill till recently when coincidently I was sawing white oak trailer decking.   I do so little sawing it doesn't make sense for me to sharpen. 

called local guy and got a big lecture on proper band tension, but he said he would take them back and "double check the set"

Now onto tension, my mill is just a threaded rod.   I put the band on loose,   Check the tracking and fire it up.   It will flop up and down and I tighten until i stop the flop.  This is unscientific I realize but seems to work fine and with most bands yields good results.

That does not sound like enough tension to me, if you only tighten until they don't flop.

     It doesn't sound like enough to me either.  But I think at least one band manufacturer recommends something like that as procedure.

Keep tightening till it starts to vibrate again aand then back off till it just smooths out.

My tension methods may be suspect, but in my defense, I have milled over 20,000 bdft of lumber doing this and have NEVER broken a band, not one.  The only time i have ever had any trouble with blade tracking (other than dull) was with these bands on their 5th resharp from a specific operation with a spotty reputation (as I am finding out locally) while other similar bands resharped from someone else is no problem.  Bottom line is I don't believe my tension is the issue, but I may try the LeeB's method next time Im out there....
