Top job. Re: your vibration getting to the work,you can make very effective isolating motor mounts using the heavy rubbers from the spindle of shock absorbers they are about 1 1/4 dia by 1/2 inch thick. get 8 .Use 4 to bolt motor to a plate and then seperate a second plate from the first using 4 rubbers and 4 bolts on the corners. It is this second plate that is bolted down. Also the drive pulley is a long way from the bearing ,that can cause problems also. All the best
Looks very good but it sounds like it runs pretty slow, more like a sander than a "grinder". You could change the pulleys and get more SFPM out of it.
@Thetruthishere11 Using the top of the belt means the dust comes right towards you, instead you would remove the platen and use the front. It's as big as it needs to be to allow for 72 inches of belt ;-)
Wow, impressive job, it looks like something factory made, not home made. I think if you isolated the motor with rubber busings it would do the trick, as far as reducing vibrations. I'm going to build a grinder like yours, I think your simple but effective design is excellent. Thanks for showing it.
Thanks for the comments, I still have some fine tuning to do on the drive mechanism, vibrations are getting up to the working surface. I need to find a way to dampen the vibrations, I'm thinking of re-designing the motor mount so it's not mounted to the vertical shaft of the stand.

@helicrashpro I had upgraded the motor and pulley system, please see my other video called "DIY grinder, now with more power!!!"

Hello! What do you think, could a washing machine's engine power such a kickass belt grinder? :D

Like J said, get the Fenner power twist belt. I had a vibration problem and that belt fixed it completely

Have you tried using a power twist belt made by Fenner drives to reduce the vibration?

unless you are a pro knife sharpner seems like an awful pricey machine to keep your pocket knife and a couple of kitchen kives sharp

It is more of an item for people that make the knife not sharpen.

Is there anywhere I could get plans for this? Its about as close to a KMG as i'll get without buying a KMG.

Very nice design, sorry about the vibration tho, that's a bummer but I bet you are right its the drivetrain/motor.
