Fix the LTAGA Sharpener or Buy a New CBN Sharpener?
« on: November 28, 2017, 12:46:14 PM »
I have been in the FF for a while now, but over in the Logging and Chainsaw forms.  I just purchased a new-to-me LT40HD (1995) and find this Sawmilling form very interesting!  A LTAGA sharpener came with the mill, but the previous owner said the auto-sharp control box is non functional.  Woodmizer gave me a replacement price for the box at $400 plus (Canadian).  Those of you that have sharpening experience, if you were me, would you fix the LTAGA or take the $400 and put it towards a new CBN sharpener?  If you think CBN is the way to go, would you get the BMST50 (manual) at $1800 Canadian or the BMS250 (automatic) at $2700 Canadian?  At this point I am mostly sawing for myself and would likely sharpen about 50 blades a year.  In a few years I plan to do some custom work.  I would be ok with the slower rate of sharpening the BMST50, but am curious if there is much difference in the quality of sharpening between the manual and automatic CBN sharpeners?  Are there other companies make sharpeners?  I see Cooks do, but I think they are not CBN wheels?  One more angle, I may be able to get a retired instrumentation tech to check the board for me, but I cannot find a schematic for the printed circuit board.  Woodmizer does not have it.  Anyone out there every repair the printed circuit board on the auto-sharp control box?  Maybe a resistor or something is bad and can be soldered in by someone with those talents - not me that is for sure!
Thanks and looking forward to hearing back.

I have been looking at those sharpeners, and if I understand it right, the manual is a combo, it comes with a setter, and the auto does not.
I have not heard any differences in the quality of their performance, but have no first hand experience.
Old LT40HD, old log truck, old MM forklift, and several huskies.

I've had a drag sharpener and now have a BMS250.  It's a fine machine, I wish I had bought it first.

For only 50 blades a year you may be better served to use a resharp service. That said, if you have a sharpener you will likely find that you sharpen more often and get better cuts. I can't speak to the CBN sharpener, don't have one. I do have an old LTAGA that I no longer use since getting a Cooks that came along with my mill when I bought it used several years ago.
