    do you have to spend alot of money on a blade grinder to sharpen blades correctly or can you use a regular bench grinder to do the same job.thanks for your help :waving:

    I use a simple 6 dollar file and do a perfect job sharpening my don't need to be able to shave with the blade, as they don't even come like that from the factory...

    Simply get a hand held 90 degree grinder, can't use bench grinders on most blades any way. The blade may not be perfect but it is good enough.

    I sharpen up to as many as 60 blades a week with a 1 HP bench grinder...been doing it for 11 years now too.

    The shop I used to work at uses a bench grinder and one of the guys uses an angle grinder. I haven't had any problems in 3 years with them.

    I bought a $29.00 bench grinder from Lowe's. This is not your typical bench grinder is especially designed for sharpening knives and lawn mower blades. The grinding wheel is about 1.25 or 1.5 inches wide, about 8 or 9 inches tall and has a water basin at the bottom to keep the wheel wet. The wheel rotates much slower than a regular bench grinder, and with the water basin filled, you don't have to worry about burning the metal. It has a guide on the front to rest the blade on for different grinding angles and to help keep the blade at or near parallel to the horizontal plane of the wheel. It puts a great cutting edge on the mower blades and definitely was worth the $29 in my opinion. It also will put a real good edge on those flat-tipped screw drivers and old Ginsu knives you might have in the bottom drawer of the kitchen cabinet. :D

    To answer the question "you ask", a regular bench grinder will sharpen a standard blade just as fast and as well as a $400/$600 dedicated machine.
    Anything else is up to you..........

    How long ago did you purchase the grinder, if lowes still has them I def will go pick one up and give it a try. Anything that will save the $40 a week I spend on having the blades sharpened at a shop is worth a try.

    If the wheel is wet it must be slinging water when you use it. Do you wear a raincoat and boots? For $29 it must be a tiny motor with no power. When you press the blade too hard against the wheel it probably will stop. Please post a picture and model number.
