Thanks to PalletPete, I have a new toy to play with. Looking forward to some sharp chains for my saws. The 441, 290, and 192 need some sharper chains before they go out on a date with me again.
I'm a little nervous to try this thing out on a $33 chain. I wish I had a chain near retirement to perfect my skills.
I still gotta' get one of those grinding discs. I am going to order some other things at the same time from Harbor Freight.
I hope to practice very carefully. I will start with my 25" chain as that's the one I use the most. I'm going to set the stop so that it barely makes contact and work it slowly.
It should have came with grinding stones. That is a lot different design than the one I got from Harbor Freight 3-4 years ago. Mine has a bicycle brake lever to operate the chain lock, squeeze & grind. The photo shows 2 holes toward the back to screw it down with. The front half is to stick out from the bench. I screwed mine to the end of piece of deck board fastened to a scrap of OSB. This makes it easy to clamp & helps to keep the surface under it clean of metal dust. The deck board was to increase the gap between the bench & the hanging chain loop making it easier to to reposition the chain without beating up my knuckles.
Mounted mine on a 2 by something, and then lock the 2x in the vice. I hate mine, good for really rough chains, other than that I hand file. I don't know if there are improvements to be made on it or if I just don't know how to use it. If you figure it out, please let me know!!
