Ordered BMS25 Sharpener

[firefighter ontheside]

I have a few 4deg blades, but I am not going to buy anymore.  I figured out I could put the blade on with the 10deg cam and just kiss the front of the tooth and then get a little gring on the deepest part of the gullet.  I send it around a second time and it is pretty much a 10deg blade now.  After I sharpen it again after use, it will be a full 10deg profile blade.

What fluid are you using?  

[firefighter ontheside]

The BMS25 is a dry grinder with a grinding wheel that has to be shaped to match the angle of the blade using a stone.

I thought you were talking about the BMS250, and had left off the "zero." :D :D

I looked it up, I see now!  

On my Cooks, the cam was only half the profile following strategy, the grind rock was the other half.  Once I got or bought the correct cam I would tailer the rock profile to get everything to match up, then I would get a piece of thick plastic card stock or similar, and press it into the rock and burn the correct profile into the plastic.  That way I always had a template to get an exact profile on the rock.

I got the 25 instead of the 250 because I left a zero off the price tag.   :D ;D

I understand!  Main thing is you'll never have to rely on someone else to keep your bands razor sharp!

Yes sir, its nice to be able to keep them sharp for myself.  I called WM this morning and they are being very helpful as usual in my experience.  They are sending me out the 7/34 cam.  I offered to send the 7/39 back to them and they said don't worry about it.  I'm gonna go out and at least mill one log today and see if I did any good at sharpening.  I feel like I was getting better at it as I went, so my first ones may not be as good.  I'm also looking into the setters so I can get one ordered soon.  I may go with the cooks cat claw.

Remember that the tooth corners need to be razor sharp and fully formed.  Just the tooth tip being ground isn't a sharp tooth.  I had several posts with pictures in the archives.

If you only hit the face, they will usually saw ok. If you want YH professional level feed rates, it has to get the back of the tooth, too, so that you have nice square chisel corners on your teeth.

I may have been guilty of that...not getting the whole tooth, especially on the ones that I re-ground from 4deg to 10deg.  I just milled a big cedar log with a 10deg that I sharpened yesterday.  It seemed to do pretty well.  It cut flat, but there were some inconsistent blade marks which I assume were because I did not re-set the teeth.  I will order the setter soon.

Has the blade in question been sharpened and/or set before?  I'm still on the factory sharpening for the balance of my blades and those ready to be sharpened either won't need to be set at all or might not be worth fussing with due to crashing into the back stops.  The second one barely skated off the top of the second back stop and still cut well, but not very straight as it knocked most or all of the set out of the bottom angled teeth.

[firefighter ontheside]

I'm sure it has.  This is one of my Woodmizer 10deg blades which I have not bought new ones in a few years, so it has likely been sharpened at least twice.  I think you could look at the teeth and see if one is damaged badly.  I usually sent my nail strike blades in for sharpening.  I don't know for sure which ones came back to me and which were replaced with new ones.  Ones that hit more substantial metal I just threw in the bottom of my outdoor cabinet.

I never send any foreign object hit blade to ReSharp.  Reason; the chances are very good that even though they may saw very well, they may also leave some irregular blade marks which is unacceptable to me.

I charge the customer for the strike and fling them on my damaged blade pile.

[firefighter ontheside]

Lynn, that's a good policy to have for quality control and you're not out anything since the customer paid for the blade.
